Broadband – A European Issue

Fast broadband is digital oxygen, essential for Europe’s prosperity, said Neelie Kroes, European Commissioner for Digital Agenda.

 

It’s already published in a paper by the European Commission. The strategy “Europe 2020 for smart, suitable and inclusive growth” states that broadband infrastructure for growth and jobs in Europe are essential. The digital dividend could be estimated that the European economic are gain an additional market value of 63 to 165 billion Euros.

 

Following the economic and financial crisis, the EU sees the expansion of fast Internet connection is one of the growth areas that will be important for the economic recovery of Europe. The cross-linking of the 27 EU member states has proved itself in the financial crisis. It also shows that no nation-state in Europe deal with problems and challenges alone.

 

Outwardly, the EU is more and more with one device. With the Treaty of Lisbon 2009, there is a European foreign minister who represents the interests of the EU in the world. With this strong external effect to the will of the EU must e accompanied by improved internal coordination.

 

Europe is to Fragmented

 

The temptation to lapse after the crisis in economic nationalism wants to counter the EU to the European growth on its feet by world. But a strong internal market is necessary. It exists at the moments, although legally, but EU companies and workers often reach practical limits it comes to act across national boundaries. While you have to struggle with a fragmented market in Europe, they can be competitors from the USA, and china, which rely on their large domestic markets.

 

The strategy paper of the European commission stresses the willingness of the EU to express to create an open service market. Through the implementation of the EU Services Guidelines, trade in private service could increase by 45% while direct investment increased by 25%, thus leading to a rise in GDP of between 0.5% and 1.5%. It is the strategy “Europe 2020”.

 

 

Smart Growth Thanks to Broadband Technology

 

The three pillars, which should be on the recovery of the European Economic Area, smart, sustainable and inclusive growth, include goals such as climate change and employment. Smart growth is also part of the digital society, which target the EU: initiative” A digital Agenda for Europe”.

 

The above-described internal market should be supported among others by the strong digital networking. For this purpose, the 800 MHz frequency band to be used in all EU countries for the development of mobile broadband connections. By 2013, all Europeans have access to broadband Internet. By 2020, every EU citizen can surf with at least 30Mbit/s. Half of Europeans should be able to go at this time of up to 100Mbit/s online.

 

To avoid interference, it is the will of the EU, the member states in the development closely. The Only way to ensure is that you can surf in Europe limitless. This is an important requirement for online services, which are offered as part of a single European market. To get closer to this goal, the EU aims to create improved conditions. These include the promotion of multi-territorial licenses, adequate protection and fair compensation for rights holders and active support for the digitization of Europe-s rich cultural heritage, as well as refinement of the global governance of the Internet — the strategy “Europe 2020”. Specially, the European investment Bank (EIB) increase loans, which it presents annually for the development of broadband available. Currently, there are two billion euros annually.

LTE Smartphones

The first LTE Smartphone brough the Korean company Samsung with model “Craft” on the market, it is from the regional provider MetroPCS LTE in its LTE network in Las Vegas and currently offered in many other urban regions.

 

The Craft dominated the radion data technology LTE and common in the US technology of the third generation mobile CDMA 2000. The latter is also urgently needed, as is still the problem of voice transmission through LTE unresolved. Must the “Craft”, when a phone call is made, switch to the CDMA network. Then abort the current download and it can simultaneously send and receive in two technologies and the unit now not even. In short: if you surf and there is a phone call, you can fly from the Internet.

 

According to the manufacturers and mobile operators 2011 is the year of LTE smartphones. This applies first of all to the market in the U.S. Here is the LTE rollout in the area so far advanced that there are enough customers for such devices.

 

Besides the already mentioned Craft by Samsung, there are no Metro PCS, a second LTE smartphone of the Korean Samsung “Galaxy Indulge”.

 

The “Thunderbolt”, were announced as the new LTE Smartphone by the Taiwanese company HTC, and the US. Mobile phone manufacture Motorola model “Bionic” and the Korean LG model “Revolution”.

 

Tips for LTE Smartphones

 

And LTE Smartphone should be proficient in addition to the latest and fastest data transfer technology, the transmission in UMTS networks including HSPA(and possibly HSPA+) with GPRS and EDGE and GSM networks in the second generation mobile. It must be as quickly as possible. Finally, it will take years for the LTE networks everywhere. And many customers want apart from the major urban centers to the mobile internet.

 

When purchasing a LTE Smartphone, an important point is to know the telephone solution. This equipment is recommended to perform without net change, when you call out. However, currently, it’s not yet clear when devices will have this capability on the market.

LTE Netbooks Guides

An LTE netbook is a small, portable computer with a built-in wireless modem that can send and receive with the LTE technology.

Networks usually have a screen with a screen size less than twelve inches, and the keyboard is much smaller. They are designed as a device with which it mainly goes mobile to the Internet. For other functions, such as writing or creating graphics are much less suitable.

Currently there are three LTE netbooks, which have already been presented to the public. All three are not on the market. The first netbook has been released for the LTE network of U.S. LTE operator Verizon Wireless.

 

The LTE Modems

The built-in LTE Modem into the netbook is a small wireless transmitter that is located inside the computer, and not visible from the outside. While sticks, routers an modems are connected in card form from the outside through a slot to the device, they are hidden under the hood here. The advantage of slots, such as the USB ports free for the other functions such as USB memory sticks.

These LTE modems to be installed in portable computers offer the chipmaker to already. They will be installed by netbook manufacturers buy only in more devices, if a sufficiently large market for such LTE netbooks has formed. First choice as a modem first LTE surf sticks will be, with which existing mobile computers for the new wireless data technology to be retrofitted.

 

Three Netbooks in the race

 

There are currently three LTE netbooks, which were presented to the publice. All three have been upgraded on the basis of existing models with an LTE radio modem. It is already clear that this will be the path of development, based on the most mobile LTE computer company, a successful model is upgraded with the new technology and is possibly still in the area for camera or hard disk.

South Korea’s Samsung showed the first LTE netbook at the beginning of 2010, the Samsung N150 LTE. It has been long on the market and according to experts, it’s a netbook with many others features such as LTE-enabled version with built-in wireless modem.

The first LTE netbook you will probably be able to buy is in the USA, since the Apple New iPad released, many PC manufacturers follow the trend, but there are many factors under worry. First, the 4G LTE band compatibility is big problem, because in different areas, the deployed 4G LTE spectrums are completely different, so there will be many brand models for even a single netbook. If one manufacturer want to produce on model to compatible with all the 4g LTE networks, it’s obvious unpractical. With higher price, the customer may not give a shit. Second, the power supply is a big headache in 3G netbook. The operation system Android and IOS both consumes power in large volumes; the battery with the device is not enough. When running on 4G, netbooks need more power, then it’s also a problem for manufacturers.

But with mobile power bank, the netbook could find a acceptable solution for power. HUAWEI E5756 is a device with power bank and WiFi router functions 2 in 1. It’s a good solution during this time, but it support HSPA+ 42Mbps download speed ,which seems for 3G Advanced network, not 4G.

 

How Can We Benefit from 4G LTE Network?

Firstly, LTE provides average download (30 Megabits) and peak (100 Megabits) speeds, which are much higher than the current ones. Also, a substantial increase in the speed of ascent (50 Megabits), so important especially for customers of the business segments, and for all information related to the use of cloud computing.

And let us not forget that it also means lower latencies (35 m/sec) network, which is essential for new services (network games, enterprise applications…)

Frequency bands
It is important to know about which bands will be operated. The first, 2600 Mhz is intended for coverage in areas of high population density, it has less penetration indoors, but acquired bandwidth will provide maximum speeds (surpassing the 100 Mbps of download).

The second acquired band is located on 800 Mhz, frequency that will allow much better penetration indoors and cover larger surfaces, so it will probably go to coverage in rural areas. The size of the band acquired will allow a maximum speed offered by less than 50 Mbps service. The availability to radiate this band probably has to wait until 2015.

The first LTE device on the market
To access services over LTE, operator had selected the modem Huawei E589 (also named HUAWEI E589u-12), which is also compatible with the current network 3G.

 

New services and applications of 4G LTE

1. The explosion of ‘the cloud’
Cloud storage: for work or make back-ups at the same speed as if it were on your local disk. Documents, videos, music… shared or for personal use, with the information always accessible from anywhere and type of connection.

Applications in the cloud: high speed and low latency of the LTE connections make reality the concept of working in the cloud, allowing working with applications resident in the ‘cloud’ as if they were on your own computer.
2. HD videoconferencing
Real-time chat via video conference with the highest quality, without delays and latencies. It is necessary to have the appropriate devices: HD cameras and the application, , to start enjoying it on the LTE connection.
In addition to the enormous contribution of this type of services for private clients by putting them in a communication and closeness with family and friends, these services are important facilitators for professional offering speed and economy on the needs of coordination at a distance, by incorporating a quality and naturalness that almost replaces the “face-to-face” meetings.
3 eHealth
Services as “Side by Side” Telephone based on the LTE network, allow the patient to stay in quiet surroundings and without offsets, while kept in communication and being cared for by specialists.

 

The LTE connection allowed, in real time, numerous diagnostic or control tests made in his house and instantly send information about their State of health at the Medical Center for its monitoring: high quality images in real time, result control of sugar or stress tests, talk to a doctor with video conferencing high definition, etc.

4 e-Gamming
It is no longer needed at home game or the game console. The high speed offered by LTE along with low latency makes this technology very attractive to enjoy the online games. It binds to the new dynamics of game servers in network, free to customers of the need to have video consoles and games, entering mode subscription to these services in the cloud.

5. Services in high definition TV and 3D Videos

In the LTE environment, TV and video services reaches its greatest exponent. The powerful low latencies and bandwidth allow video club services, video streaming and high-definition and 3D TV broadcasting develop their potential to the maximum.

6 Immersive Communications
This category refers to completely virtual Telephone services. Solutions that facilitating labor mobility, management of meetings among multi-country teams, with a realism that contributes to the good results and good relations between persons of the team. This solution, completely virtual, allows you to delegate the management of the application in order to work with it from any computer in the network: laptop, tablet, from any place where a high performance network, such as the LTE network is available.

 

 

We hope that all these details serve for you to hereafter, when the term 4G or LTE will begin to be extensively mentioned, have a much clearer vision of this new step in mobile communications.

 

LTE Antennas—You will always need double

Those who wants to surf with LTE really fast, which can improve the reception of the radio signal by additional antenna.

 

But beware: while the UMTS radio technology usually received via an antenna, LTE always uses the multi-antenna technology. It’s on two antennas to send and receive data. So you have to always connect two antennas to be receiver. Suitable antennas are double it commercially as a total package; they sometimes look like a tool. If in doubt, ask if there is a dual antenna.

 

Before you buy the antenna that your receiver is ready for connection to a pair of antennas. Receivers are modems such as routers, surf stick modems in card form or radio modems that are built already in tablet, notebook or netbook. If you do not know it yourself, ask the dealer or the seller, whether your device has such a connection for a dual antenna.

 

 

Types of Antennas and antenna purchase

 

There are two types of antenna for LTE: The Omni-directional antennas can be placed up and receive the signal from any direction. However, there are also good and bad places for the erection of the antenna.

 

The directional antennas generally provide a much better result; they have to be aligned with the respective LTE mast. You should know, however, where are the nearest towers. This information provides the agency on a separate card. Simply enter the city, and then you will be presented in a easy map to set of transmission towers around your home or office.

 

The seller of LTE antennas often offer a complete package in which is already containing everything they need. The antenna pair, the associated connection cables, often even a holder for parallel installation of two antennas. Suitable antenna packages are also on LTE mobile operators sometimes offers, in addition to the receiving equipment such as a modem or router.

 

Our tips for easy installation

 

During the assembly, proceed as follows: first, find the right location, either inside the home or outside. You connect the antenna to your computer, and check the signal strength at various locations. You can see the signal strength on the modem. Some vendors offer LTE signal strength measurements via Internet. If you want to do the test, you have to measure computer and a speedometer, the transmission speed at different locations.

 

Where the reception is strongest, you should place the antenna. When you place the antenna inside your own house, then close to or directly on the window, from which you get the best reception. In this case, make sure the antenna distance from the modem or other electronic devices, such as television, radio, PC, electric fields interfere with the signal.

 

The second way to set up the antenna outside of the home, is therefore at the top of the attice, on the roof or on an outside wall. Whichever course choose, you should keep at least one meter away from poles, pipes or railings. Under no circumstances should you screw the antenna on a metal plate or wall. If you need to put the antenna on a mast, then you must sit above the top of the mast, where possible, over the roof edge. The principle is around the antenna, there will be no metal—metal shields radio signals.

 

When you buy yourself a pair of directional antennas, in addition to make two points: First, then antennas are mounted at the same height, and secondly, they are aligned parallel to each standing, to the nearest mast. It’s best to consult it in stores.

Video Telephone over LTE

High data rates, low latency (delay): LTE is technically well suited for video calls.

For video telephone, when receiving a certain data transmission, it also need sending data out to the other side. The slight delay in LTE network also facilitate video calling but the new communication to take place in real time.

LTE: In theory, well suited

The connection should also be subject to no greater variations because this can lead to problems in understanding and distorted images. The data rates of 100Mbps downstream and 50 Mbps upload in LTE offer many possibilities. While the theoretical maximum values, however, is likely to come with LTE usually have the necessary 200Kbit/s.

Short response times (latency) are also necessary for video calling, not too long to wait for the response of the other person, who then may intersect with what you’re sending.

There are obstacles

Currently, video telephone over LTE has certain difficulties. The voice transmission is carried over the internet, which is called Voice over IP (VoIP). At steady-LTE tariff Vodafone VoIP is not allowed; thus here is video calling possible.

 

What a hindrance is the sales data added. The LTE tariffs have a monthly data limit. This is achieved, the speed is reduced, usually to 384Kbit/s, so video calling is possible, but the connection is faster, then the limit is available for other applications, only partially available. Per hour, video calling 100-200 megabytes incur data traffic. In the current LTE tariffs for people who like to chat and much, relatively soon is closing, especially if they have other multimedia applications run on the LTE line.

 

Telephoning With LTE—VoLTE or Volga

There are surf sticks, router or data cards for computers, but Smartphone owners will not only surf but also calling and texting. There are different technical ways to offer besides faster data transfer and telephony. Which path to choose LTE network operator, is meanwhile not clear, there are some uncertainties. It’s also unclear whether the new LTE Smartphone currently really offer what you would expect from such a device into a super fast network. The usual headache of first users is that they usually report functions that the networks are running slowly or with batteries that are empty after a few hours of use.

 

One thing is clear that the upgrading of the networks on additional functions such as the one hand calls for the network operator is not free; it will cost a lot of money. On the other hand, the users want surf and even better with new expensive LTE Smartphone, the expensive rates at least as good as the old UMTS model.

 

The Rustic Method: Back to GSM and UMTS

 

The simplest theoretical method to offer telephone is reliance on older networks. When the LTE Smartphone to surf the LTE network, a call comes, it comes out of the LTE network and into the GSM or UMTS network calls. In other words, you can surf the LTE network or the GSM/UMTS network calls. It would be theoretically possible. However, the simultaneous operation of two transceivers will bring some problems to a mobile device, such as lousy battery life. The second disadvantage of having recourse to old networks apart from the interruption of the data link: it takes significantly longer for a voice connection is established.

For the rustic solution, that recourse to an old wireless network and call interruptions limited data usage via LTE, has been the American mobile operator Metro PCS decided. Metro PCS offered worldwide in the first LTE Smartphone in its new LTE network, and how many customers you could win it, concealing the company. But apparently saw Metro action, it now wants to upgrade the telephony technology to VoLTE shortly.

The Majority Solution: Voice over LTE, VoLTE

Voice over LTE ( VoLTE ) describes a new technology for the transfer of mobile phone calls in LTE network. The change from GSM and UMTS phone technology to VoLTE is – in simple terms, the shift from analog or ISDN lines to IP telephony comparable.

 

With the old telephony technology, a separate line for conversation is provided, the data on a different transmission run secreted. With the new networks, everything runs on Internet technologies and the talks are treated as data packets that are transmitted along with other data packets. Therefore one must of course int eh LTE core network set up an additional new location, this is called the IP Multimedia Subsystem. With the system, calls are treated like simple Internet files.

 

This solution is called VoLTE, it is currently being sought by many network operators worldwide, the U.S. now wants to implement next to Metro PCS LTE is also the largest provider Verizon Wireless. It is the technical solution that will end all use LTE operators, unless they agree. But it is costly – the mobile network operators have to adapt their IT infrastructure to the new system.

 

The Outsider: Volga

Therefore we have devised a further intermediate step that once does not cost as much and also gives good results in terms of the speed of a connection setup or the voice quality. The technology is called Volga, which is the abbreviation for anything cumbersome expression Voice over LTE via Generic Access.

 

Using this technology, an additional point will be created through which the calls go, but this time not inside, it’s outside the LTE network. This new board is the VANC, which stands for Volga Access Network Controller. About him, so to speak, the phone calls are funneled into the LTE core network, without having to change anything in the core network itself or adapt.  That is, they say, Volga, is faster and more cost-effective than the introduction of VoLTE.

 

 

 

SMS in LTE—Only use the time-proven Technology

With new LTE Smartphones, which are available in many markets now, users want to get exactly the same services as the old UMTS smartphones, the service includes SMS.

 

The SMS is, in evolutionary, actually a waste product. In GSM and UMTS networks, there is so-called signaling channel, which is used for user to display the signal strength of its cellular network. There was in the early days of mobile phones still free space and so they came up with the idea of sending short text messages via this radio channel. The success surprised the inventor. Developed to today, some phones seems to become the second function of a mobile phone, and this function should continue under LTE netwoks.

 

SMS is also continued on the old networks

 

At the point under the LTE network, which is responsible for signaling data, SMS is then processed over GSM or UMTS networks forwarded. Thus, even a lot of SMS services continue to be used, which have proven themselves – such as the configuration of mobile phones via SMS – without having to make major changes. The technical term for this SMS technology in LTE networks “ Circuit Switched Fallback for SMS”.

 

The Future: SMS as a simple Internet File

 

The alternative is to completely treat the SMS in LTE network. This will eventually be made. But for this you have to build an entirely new element in LTE networks – the so-called IP multimedia Subsystem. This element is everything – to put it simply – as an Internet file treats – from voice call up just to SMS.

 

This is complex, as the example shows SMS:  If you want to existing services – such as smartphone SMS configuration – switch to the new mode of transmission, you need to build these services virtually from scratch – with the provider as the terminal of the customer. This costs time and money.

LTE Mobile TV

The new wireless data technology LTE offers such high speeds, so that users could continue watching television on laptop or tablet PC when walking.

 

Mobile TV has long been touted, but could not yet penetrated the mass market. Well, perhaps the mobile operators offer this service via LTE later future. But one thing is clear: there will not be in vain for mobile TV. For good reception, only if the operators assure a TV subscribers in the LTE network at a certain minimum speed of transmission, in other words allocating a portion of the transmission capacity of its LTE networks for broadcasting, the customer could watch mobile TV.

 

The LTE Technology is Already There

 

With such equipment on board, a tablet PC could be upgraded into a mobile multimedia center, so it could receive sound and picture with good quality from any location via the Internet. Provided there is fast data connection at the site, either via HSPA+, which offers maximum 42 megabits per second, or if over LTE, it creates the radio channel at 50 to 100 Mbit/s speed.

 

Lack of Radio Capacity

 

If you want to transfer movies in real time over the Internet, you need at least one current transmission speed of 2.5 megabits per second, it should be high-resolution strip 10 megabits per second. These are the technical requirements for proper live broadcast. So if you want to offer television or high-definition television in this way, the operator must guarantee the customer under minimum speeds.

 

Here, TV images are also used as data packets over the Internet, however, via a DSL line and not over the air. Because IPTV is the telecom connected with further additional servies such as phone and Internet, known as a DSL 16000 connection is required – ie a line which in practice creates constant around 13 mbit/s.

 

Meanwhile, it is mobile television- and especially high-definition mobile television or even 3D TV- enter via LTE not so popular for mass market: the current wireless capacity are probably hardly enough of a large number of customers with these minimum speeds. Because it’s not enough, such a tariff is only interesting when it offered in all major cities and conurbations.

 

 

Mobile TV: Current Situation and Prospects

 

Currently, there are some deals on mobile television on smartphones. But that’s so far not overwhelming TV experience: In the early days there were frequent interruptions in sound and image, as a football fan, you might not like that. Then after the problem is fixed, you have to dodge sometimes even to the GSM network, the image and sound worse, said the testers.

 

If mobile TV has much better experience than home TV, there is only one way: A laptop with a 4G surfstick or wireless modem that can receive via DVB-T, The regular broadcast television signals. This kind of television is largely expanded coverage, but you can get in many regions of only a few publice channels and onl in the urban areas, there are also private problem.

 

It’s possible that mobile TV comes only with LTE-advanced. One this is that anyone who is watching television will have to pay an additional fare.

Mobile Gaming Over LTE

The mobile technology Long Term Evolution (LTE) provides for gaming on the go.

 

Not only high data rates contribute to an improved gaming experience and more sophisticated applications. Even low response times ensure smooth gameplay fun.

 

Netbooks, Smartphones, Tablets and Consoles

 

Netbooks and notebooks are based on your home PC when it comes to games, so single-player or multiplayer title, or even online games. Portable consoles like Nintendo DSi or the playstation Portable (PSP) was a few years ago exclusive consoles for mobile players. Meanwhile, however, they are beset by smartphones. As far as processing power and screen size to bring smartphones to more and more. Also controlling approaches to partially: Sony has released a smartphone that has a rather classic QWERTY keyboard and directional pad buttons for video games.

 

Many games today require an Internet connection, but generally very little bandwidth. The data for the game are stored on your PC, laptop, tablet or smartphone. Between the game server and the computer of the player need only a few data are exchanged. Depending on the genre are the position data of the character, their actions and their impact on the game environment and the player. There need not a combination of a few hundred kilobits per second(Kbit/s). A stable connection via HSDPA also do this.

 

 

Latencies must fall

 

What’s important than the data rate is the reaction time. And input of the player must match the server of the online game will be transmitted. The response, which indicates the change in the game environment or to other players must be sent again on the way to the player. This delay is known as latency. The higher the latency, the more difficult the game is control. For games that require quick reactions, a high latency often means the difference between winning and losing, between fun and frustration.

 

LTE comes into play here. The mobile technology offers not only high data rates but also low latency that will finally compete with stationary terminals. During a DSL connection has 20-50 millisecond delay, it is the case of UMTS and HSDPA 170-200 still 60-80 millisecond. A lag of one or two tenths of a second sound like much, but in games quite noticeable and measurable impact.

 

With LTE latency to 20 milliseconds are possible. In this way, the delays between the input and reaction are hardly recognizable. Even for players who move into professional gaming leagues, LTE is a real option for Sun.

 

Onlive – An alternative

 

Another way of mobile gaming for LTE users could open in the future: the games-on-demand service onlive. This project from the USA is based on streaming as a method for uncomplicated video games. The game data is stored on high-performance computers in the server park of onlive. The hardware of the player must support the demands of the game not once, just for mobile surfers an argument, they are not usually traveling with technically upgraded PCS.

 

The game comes to video stream rather than on the device, where it is acoording to data from onlive in about one millisecond decompressed. The inpurts of the player as playing online games submitted to the online server and returns the result of interaction. To represent games in HD 720p resolution, you need at least 5-megabit connection, which also remains stable. And HSDPA connection not afford it. As with other games that take place online, with games on onlive the latency is a critical factor. The low latency and LTE are again an argument. Heading to play the latest, sophisticated graphic title on the netbook over an LTE connection, then perhaps is the way for mobile players.
