LTE – Up to 172.6Mbit/s

The 3^rd Generation Partnership Project (3GPP) standardized wireless technology Long Term Evolution (LTE). 3GPP is a consortium of several institutes.

The project also defines standards for other mobile technologies such as HSPA. In Release 8 of the 3GPP LTE in 2008 for the first time defined. Here, speed and technology used were committed.

Different Technologies for Increasing the Data Rate

With Release 8, the theoretical top speed with LTE on 172.8 Mbit/s when receiving data (download) and up to 57.6 Mbit/s is limited to send data.

The speeds are made possible by a number of technical parameters. First, a 16 fold quadrature amplitude modulation (QAM) is used, a technology that enables more data to be carried on a shaft.

By a plurality of antennas at both transmitters on the receiver side as the speed is increased in both directions as well. This technology is called MIMO (Multiple Input Multiple Output). On LTE Release 8, two independent antennas are used (2 x 2 MIMO). Essential for the increase in speed is also the frequency bandwidth of the connection. In this case, up to 20 MHz, in order to transmit data.

In reality, the network operators are indeed technology such as MIMO and QAM are available, but there is a lack of sufficient bandwidth. This is spread across multiple network operators, so that in practice 50 to 75Mbit/s are technically feasible in the download.

LTE Standardization

3GPP is initiative responsible for the standardization of LTE mobile technology. 3GPP Stands for Third Generation Partnership project.

The initiative focuses on the standardization of LTE and third generation wireless technologies such as UMTS.

Technical specifications of LTE

In various releases since 1999, the 3GPP initiative has published technical specifications for different areas of mobile communications technology. The release 8 focuses on the standardization of LTE technology and is the most recently completed. In releases 9 AND 10 further standardization of LTE technology are made.

Release 9 is concerned with improvements and enhancements of HSPA and LTE Release 10 defines the technical specifications of LTE-Advanced. For Release 9, the development of the remaining issues to be completed in March 2011. Release 10 is still under development, a completion data is unknown.

About 3GPP

3GPP was created in 1988 with the goal of creating a global mobile applicable third generation system. Practically to the standardization by 3GPP to enable the users to get in as many networks worldwide with the same equipment, the same services as in his home network. The detailed technical specifications are intended to describe all aspects of mobile technology so precise that the mobile devices of all manufacturers without errors on all cellular functions.

The initiative consists of 3GPP Organizational Partners (OPs) and Market Representation Partner (MRP). OP’s are the world’s defining standards bodies in the IT industry: the Association of Radio Industries and Business, Japan (ARIB), the European Telecommunications Standards Institute (ETSI), the Alliance for Telecommunications Industry Solutions, USA (ATIS), the Telecommunications Technology Associations Korea (TTA), the Telecommunications Technology Committee, Japan (TTC) and the China Communications Standards Association (CCSA). About this Organizational Partners worldwide a majority of all mobile operators, manufacturers and regulators is organized in the 3GPP initiative.

HUAWEI E5151 Mobile WAN LAN 3G WiFI Router Review

HUAWEI E5151 3G Mobile WiFi Hotspot (also named HUAWEI E5151s-2) is one of the new mobile 3G router from HUAWEI. Focus on the application of businessmen, HUAWEI design this new model with one Ethernet port to input HUAWEI E5151 and transfer data to WiFi signal so that users could access internet. This is the special and key features of HUAWEI E5151 Pocket WiFi Hotspot.

Today, let us have a look at HUAWEI E5151 mobile WiFi and it’s specifications.

HUAWEI E5151 is in pocket size, like other HUAWEI E5 pocket WiFi models, which makes it very easy to take in hand or pocket. For most of users, it could be taken outdoors or with a trip, however it would not take much space in luggage. To meet the Ethernet connector, HUAWEI E5151 is thicker than other HUAWEI E5 mobile WiFi hotspots.

On the face, there is a LED screen which is to indicate the working status of this mobile WiFi. At the left side, it’s the HUAWEI logo. When it’s working, it will show the connection users, signal strength of 3G, battery status and SMS. At the right side, it’s the power button.

On the back, it’s a logo of HUAWEI mobile WiFi. With changeable battery, it could keep working 4 -5 hours and almost one week standby time. Below the battery, it’s the slot for 3G SIM card.

The SSID and WiFi key is on the back cover of HUAWEI E5151. Through this, you will connect the WiFi and surf internet.

At the below side of HUAWEI E5151, it’s the Ethernet port to connect the cable. This is the most attractive features of HUAWEI E5151. For most users who usually go to different countries or areas, if they buy a mobile WiFi, there may be the compatibility problem, because the 3G network bands vary in different areas. But if there is Ethernet cable, this problem would be easily solved.

To recharge the battery, in the package, there is one USB cable to help recharge the power.

LTE – Investments, Costs and Profits

Mobile operators have pulled out of the expensive purchase of UMTS licenses, the expensive construction of UMTS networks and the subsequent price of their teachings battle for customers.

But with LTE, users pay only a fraction of the transmission frequencies. For network construction, the price is the decisive criterion in selecting among the network equipment. And customers for data services in LTE networks will have to pay significantly more than what they have been accustomed to from UMTS networks.

UMTS: The more data, the more cheaper

The mobile plan has a problem; you need to inject more data into ever cheaper prices through their wireless networks. Since the new technology LTE is just right, the cost of production for fast data transmission in mobile communications should be lower. The cost per bit is lower for the network operators from four to ten times more than in HSDPA. This is also related to the fact that through new applied in LTE radio technologies, such as multiple-antenna method MIMO or the new modulation schemes OFDMA, with ten times more. LTE phones can be provided at a location with high speed internet than with UMTS. With LTE, so the profit margin is the mobile data tends to increase and the number of potential customers multiplied at one location.

LTE Expansion Cheaper than UMTS

The cost of the LTE expansion circulates different numbers. The bidding for the frequencies is already certain.

Expenditure incurred in the bidding for the frequencies, the cost for network deployment. The US firm Aircom, a network specialist, estimates that a mobile operator in Central Europe needs to spend about 670 million euros for the LTE network construction in the first year.

Lot of costs should come together after all, it must not only upgraded base stations to LTE or LTE base stations will be built, it must be a new IP-based core network to be created. And finally, the data lines must be upgraded from the base stations to the new core network to process the large amounts of data, because what good is fast wireless network if it only blcks the access to the core network. This looks like a high investment.

Pressure on network equipment

In order to make sense economically, the LTE expansion should cost only a fraction of what was spent on the construction of UMTS network, so the experts explain the Finnnish IT consultancy Rewheel. My solution to this dilemma: The network equipment should rethink their pricing somewhat.

New tariffs: LTE’s are not as bargain

After the business model was not a UMTS rousing success for many years, the mobile operators want LTE would not have to wait due to the investment pays.

And that probably means that they do not just invest less than in the UMTS networks, but they will charge higher prices at the retail level.

LTE is surely not only once at a bargain price.

Three Huawei B183 Webcube Home Broadband General Review

The UK’s operator Three had recently released two new broadband routers for home, the model numbers are HUAWEI B183 and HUAWEI B153. They are fixed line broadband and is the perfect companion for Students who need a broadband connection in there diggs, and the most important feature is (you don’t need a landline to use it) just plug into your mains and Three will do the rest.

Today, let’s have a review what’s the features of the Webcube White HUAWEI B183 home broadband Router and what it can do for us.

Appearance

Webcube HUAWEI B183 is in a very classic design, looks like an hour glass, but has a sudden glance; you may think it’s a humidifier. In simple white, the cube shape is very attractive, different any other home router, which make it looks more like a home white goods, not just a network router.

On the top side, there is signal strength indicator, if it’s not working, you may not be able to see it. And with the single strength indicator, you will see the Power and WPS button. And there is logo on this face, sometime it’s “3”. 4GLTEmall.com provider unlocked HUAWEI B183 with HUAWEI logo, no contract and no limit. The top cover could be departed from the below part, at the side of the top cover, there is external antenna port and reset button covered by a slip.

Another side of the top cover, USIM card slot and network indicators are also configured. What’s more, there is USB port around, which is for test purposes only, not for users. So for most of the users who had get it first, they may don’t know how to use, where to plug SIM card, where to power it on. From above image, you will find details part of HUAWEI B183. Now it’s easy to operate to connect network.

HSPA+ Technology

HUAWEI B183 Home Broadband from Three with the latest HSPA+ offering up to 21.1Mbps download and up to 2 -5Mbps uploads, but you can expect to receive download speeds in excess of 10Mbps which without a landline is exceptionally good. This is also an exceptional deal for renters too who only wish to use the internet occasionally or are moderate users, also great for customers in rural areas of the UK where accessing the internet is hard to acquire.

Entry Level Broadband

The B183 Webcube offers up to 5 different connections at the same time enabling other family members to be online simultaneously, with a good wireless range extended up to 30 meters away from the cube and you still get a perfect signal anywhere around your home.

Go Anywhere Broadband

The great thing with the Webcube B183 is how easy it is to carry to a friend’s home and set up in next to no time so you can share a connection with them, when you receive your B183 Webcube from Three you have a (pre-defined SSID and Network Key) that only belongs to you, in the box you will have your password and info to input, then you are able to use your new Webcube for the first time.

You may ask there is HUAWEI B153, what is it? Actually, HUAWEI Webcube B153 has almost the same appearance and size of HUAWEI B183. The main difference between HUAWEI B183 and HUAWEI B153 is that B153 supports HSDPA 7.2Mbps while B183 support peak HSPA+ 21Mbps download speed. So if to get better network link, HUAWEI B183 is a good option, but if HSDPA 7.2Mbps can meet your requirement, HUAWEI B153 is a cost budget one for home router.

What is WiMAX?

WiMAX stands for Worldwide Interoperability for Microwave Access – an international system compatibility for access to microwave frequencies. It is in a sense competes with LTE – the technology, which we wrote about earlier, for the title of the next generation of mobile networks 4G. The reason is that both technologies provide a connection for mobile terminals (smartphone, laptop) with a sufficiently large radius of action. At the same time, there are similarities with the traditional Wi-Fi.

WiMAX is the wireless technology that provides theoretical data rates up to 1 Gb/s. Designed to solve the problem of the “last mile” access to the Internet.

The problem of the “last mile”, is a link from the equipment provider to the customer directly, by phone or Internet. For example, in Europe the most common channel is DSL, using ordinary telephone line with all its shortcomings. The idea to replace the wire telephone line radio channel with sufficient speed is very tempting – a minimum of inconvenience to the user and less dependence on fragile cables.

The name WiMAX «for nerds» is IEEE 802.16, which puts it on par with other telecommunications standards. And fixed WiMAX (includes communication with the fixed customer) applies standard 802.16d, while mobile WiMAX (communicate with client in motion) uses a modification of 802.16e.

The key difference stationary (fixed) and mobile versions – in the absence of a first opportunity to “transfer” of a customer from one base station to another. Naturally, some of the mobility of customer equipment within range of the base station (10 km) is possible. Mobile version of the report provides a current revision speeds up to 30 MB/s, while the fixed – up to 75 MB/s. The theoretical limit is around 1 gigabit.

Unlike Wi-Fi (IEEE 802.11), WiMAX not only uses the license free, and licensed frequency bands – from 2 to 11 GHz. WiMAX range is much more than the Wi-Fi network, except for the transfer of the antenna. For the fixed network, as we have said, it is up to 10 km, while the mobile network is within a radius of 5 km.

The large scatter of operating frequencies creates serious problems of compatibility. For example, the optimal properties for the frequency range 2300 – 2700 MHz in most of the world is a licensed and used by intelligence services, which means that service provider will have to invest a lot of time and effort into getting permission. The range is 3400 – 3600 MHz is less problems with permissions, but penetrating power drops sharply, for example, for indoor reception may not be possible.

Finally, the cut-off frequencies of 6 GHz and above all can be used only in the line of sight due to the low penetration. For comparison, a rival LTE technology, which operates in the usual range of cellular communication in the area of 1800 MHz, has not these problems of penetration

The principle of the subscriber device (modem, phone) with WiMAX is similar both to work in the network, and to work with Wi-Fi access point. The device sends the request to the UE on the bandwidth allocation, and then logs in and gets your own channel. Then the authentication procedure and the device are issued IP-address: four-or six-digit (in a future release.) Calls to the WiMAX network will also implement IP-based, as in Skype – another similarity with the Wi-Fi-networks.

A Brief History of LTE

The short history of LTE shows only five years it took from the start until the introduction. This follows the mobile a trend that can be observed in new technologies: What is now on the market, may have a million customers in near future.

Digital Mobile Radio: from GSM to LTE

The first phone last 28 years to crack 10 million mark of users. The cable television made it in 25 years to get the phone in 9 years, the wireless data transmission in 6 years, from zero to ten million customers. Faster new technologies are accepted by the mass market.

The new LTE technologies were developed as fast as any other telecommunications technology. For comparison: In 1982, the development of GSM by “Groupie Special Mobile”. It was launched by the European Conference of Postal and Telecommunications Administrations. In 1991, the first GSM network in Finland went on the air. In 1992, GSM set internationally by the market. In 1987, the UMTS Basic Research, 1992, the frequencies stipulated for 2001 launched the first commercial UMTS network, followed by the Standards for the additional technology to quickly send HSDPA(2002) and HSUPA (2005).

The UMTS technology was initially developed hesitant, we had already a digital mobile radio standard and the number of applications for faster wireless data transfer was still very manageable. Later, the networks were constructed reluctant, partly because they had to pay high license fees and the lack of money for investment, partly because the applications bring quick profits, were not in sight.

In LTE, it goes very fast

LTE everything goes much faster. For those applications that need more and more data faster by radio are finally been on UMTS market.

LTE is considered the birth of 2004, when in Toronto, held a workshop on wireless networks and LTE. About forty mobile operators were represented, to research institutes and universities. As a result, created a study on how to rapidly develop and build a fast data network, has short response times and nearly bring the performance of a wired network.

In June 2007, the standard for new mobile technology is being committed. In 2008, Ericsson unveils the Mobile World Congress in Barcelona, the first time establishes a connection between two compact LTE terminals, there will be a transfer rate of 25 mbps per second achieved. End of 2008, the Korean company LG to introduce the first-install LTE chip, it could reach peak speed at 60Mbps.

Finally, in December 2009, the first commercial LTE network in Sweden is put into operation, in late summer and fall of 2010 in Germany, the first LTE phone masts ready.

LTE: The Fastest Developed Technology

For the Global Supplier Association, a global trade association for the mobile industry, LTE is now “ the most rapidly developing technology in the history of telecommunications.”

Meanwhile, large-scale commercial LTE networks available in many countries and areas.

Digital Dividend

The switchover to digital terrestrial television wide frequency ranges were free, the so-called digital dividend.

Only ten per cent of the original required frequencies are now claimed by the television. The rest can now be used for other functional areas such as mobile communications. The frequency bands 790-862 MHz was auctioned in May 2010 by the Federal Network Agency to reach the rural area with high speed internet. Since the development of the wired broadband in many sparsely populated areas unprofitable for network operators, the frequencies are now used as the digital dividend as so to reach all citizens.

Greater Range of 800 MHz Bands

The Federal government has to set up a broadband initiative, to every Germany citizen to enable broadband access to the Internet. Only when the rural areas are supplied in this manner, may the expansion of LTE in major cities and metropolitan areas begin.

The digital dividend frequencies are extremely popular with the network operators. Transmitters in the frequency range to 800 MHz have a longer range than the sender, for example, 2600 Mhz range. According to experts, an LTE radio cell operating at 800 MHz has an average diameter of six kilometers, an LTE radio cell with 2600 MHz average diameter 600 meters. This is due to the physical propagation characteristics of radio waves.

The Expansion can Begin

The Federal Network Agency auctioned in May 2010, the digital dividend spectrum. The three major German network operators German Telekom, Vodafone and Telefonica O2 were able to bid on two blocks. End of August 2010 until the blocks assigned to concrete. In the spectrum auction in May, the operators had only offered on capacities.

Only a concrete black was auctioned. The first black, which lies in close proximity to TV channels, was acquired by Telefonica O2. Now the company is the nearest black was released. Telekom and Vodafone both received two blacks assigned by lottery.

Now that all of auctioned spectrum blacks are assigned to fast broadband is also on the land now in the hands of the company. Network operators can now have a more focused network planning and expand their networks quickly and on, “said Matthias Kurth, President of the Federal Network Agency over the Internet magazine.

Fast Mobile Internet In Europe

The exploitation of the digital dividend is not only a concern of the Federal Government. The European Union sees this as an important step towards the universal coverage of broadband internet. Not only access for all Europeans to fast, mobile Internet will be achieved through the coordinated use of the digital dividend. In this way, even a single European market will be created. Currently, the European market is still fragmented and crisscrossed by borders. If it is possible to synchronize the wireless networks, EU citizens in coming year’s cross-border access mobile media content and mobile services.

Will you choose HUAWEI E5756 or HUAWEI E5151 for Mobile WiFi?

Around the end of 2012, HUAWEI released two new 3G HSPA+ Mobile WiFi Hotspot, someone may ask, why not 4G LTE HUAWEI E5776 or HUAWEI E589? Yes, the two 4G LTE Pocket WiFi are definitely hot with fast development of 4G networks.

Today, we will not talk about the 4G mobile hotspot because for most of users, the 4G Gadgets are in high price range; they cost too much to enjoy something new. Only technology geeks are trying to follow new products. We choose HUAWEI E5756 and HUAWEI E5151 as our today’s topic because there is something special with the two models.

First, let’s look at HUAWEI E5756 42Mbps Mobile WiFi Hotspot. It’s like its predecessor HUAWEI E587, E586, E560, has the functions as E5, but supports 10 users to share WiFi network. With USB cable, one more device could access internet. And its peak speed reach up to 42Mbps under Dual cell HSPA+ technology. These features looks much like HUAWEI E587 42Mbps Mobile Hotspot, but HUAWEI E5756 have some special features such as it would work as a mobile power bank, which incorporates battery capacity of lasting 10 hours online usage. And it could output power to many devices such as iPhone, iPad, Android tablets or Smart phones. In case, if you are lucky to get HUAWEI E5756, you will get gadget with power bank and 3G WiFi router functions 2 in 1. What amazing!

By the way, we found HUAWEI E5756 could support IPV 6, which are not compatible with by most existed network devices. So with this powerful function and practical application functions, HUAWEI E5756 would be HUAWEI new flagship model in near future.

Then let’s look at HUAWEI E5151 WAN LAN 3G WiFi Router, it has the basic function as 3G Pocket WiFi to supports 5 users to access internet, keeping working at 4 to 5 hours with changeable battery. Peak download speed via 3G is 21Mbps. The main difference and also its key features is that there is a Ethernet port at the side this device, which means, if you are outdoors, you could take it around to let it work as a portable router; when you back home or in office, it could get connected with the Ethernet cable, then it becomes a stationary router to offer wireless signal.

With Ethernet cable, HUAWEI E5151 could support peak download speed at 100Mbps. If you are abroad for business trip, it would be better to take this one, because you don’t need to find the shop to buy SIM card, if there is Ethernet cable for network, your multiple electronics could share network simultaneously.

They are both in simple design and easy operation, and released for different application, but they are user friendly. Customer could choose the preferred one and enjoy the easy experience of surfing internet. In our opinion, if you have many electronics or gadgets demanding continuous power supply, it’s better to take HUAWEI E5756 Mobile Power Bank Router, but if you are a businessman who usually goes to different countries or areas, it’s better to take HUAWEI E5151 WAN LAN WiFi Router.

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.
