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.

With LTE—Playing Games in the cloud

One possible application for the mobile LTE technology is playing in the cloud. One must install or download the appropriate games; just the inputs are transmitted by radio.

Is LTE cloud gaming ready?

For the user, it has several advantages: as with other cloud offerings from the software domain (Saas – Software as a Service), the users don’t need upload data to the computer – no long installation time and space problems. If you want to start a game, you click on it just so perfect for vacations. Furthermore, users could elaborate new games and don’t need to upgraded the gamer on PC. They could just do it on the cloud server.

LTE makes cloud gaming mobile

In conjunction with the LTE Mobile Technology, this idea can now think ahead for mobile. Namely, cloud gaming don’t have great demands on the terminal – to play on smartphones and tablets is therefore technically possible. But the internet connection is the main problem now. With wireless LTE gadgets, to keep it in stable connection, it’s still a trouble.

TO transfer the input is not a problem because here are a few data sent. Consuming is the stream of the game itself, because even though no program data is transmitted, a video stream is always a data-intensive business. With data rates in UMTS networks, the sink in some cased significantly less than 1 Mbit/s, it may skip. Most will satisfy even short interruptions to hinder the fun. LTE offers higher data rates, which promised more stability on the one hand and on the other hand, LTE also allows streams of higher quality in HD or 3D.

Another problem is that the cloud gaming previously tied to fixed lines, is now changing to wireless. The delay between the input and a visible reaction is critical for game playing and experience. If I press a button and the character sets on my screen at the command after a half-second, no fun and does in gmaes that focus on responsiveness, certain defeat. UMTS had adapted a latency of 300 to 500 milliseconds, for gaming on the cloud so little. LTE can only come close here to landlines, as well as LTE are the 20 TO MILLISECONDS. Such delays are hardly noticeable and allow a smooth gaming experience.

Ubitus and telecoms work

Connect to LTE and cloud gaming, that was the objective set as the cloud provider Ubitus. Together with the telecom vendors exhibited at IFA 2011, a cloud gaming service that is designed for LTE users:

“As LTE become the leading, next generation mobile communications technology, we have at Ubitus worked hard extensive provide multimedia and gaming content on LTE networks.” Said Wesley kuo, CEO of Ubitus. The Games are controllable in the browser, so no installation of a particular program is nesscessary.

LTE in 2013: The Top 5 predictions

While it first appeared as a live commercial network technology at the tail end of 2009, it really wasn’t until 2011 that LTE could really be called a mainstream technology. It really hit the ground in 2012 but as it stands it is only really widely deployed in North America, South Korea and Japan. In 2013 however, we expect it to truly become mainstream proposition in many countries around the world, particularly in Europe.

Here then are our Top 5 predictions for LTE in 2013.

1. LTE handsets:

With more LTE networks will inevitably come more LTE handsets. It’s fairly sound logic, but the analyst figures are there to back that up. According to Boston’s Strategy Analytics global sales of LTE smartphones will triple to 275 million handsets in 2013, up from 90 million sold in 2012. It might just be numbers but in many ways it’s quite exciting. With LTE networks and LTE handsets in people’s hands the rise of cloud services can really start to accelerate and encourage innovation as companies begin to compete for dominance in this rising space.

2. Emergence of LTE in Africa:

One of most interesting areas for LTE in 2013 will be the emergence of the standard in Africa. That’s not to say it will hit the mainstream – anything but, but the technology will start to impact the continent. Vodacom is currently the only live service has launched in South Africa, with 70 active base stations at launch, while MTN is readying a limited launch service in Durban, Pretoria and Johannesburg, while Cell C has been making plans to. There are concerns such as high CAPEX costs, a lack of devices and a lack of spectrum to contend with. Nevertheless Informa Telecoms & Media is predicting 350,000 LTE subscriptions in Africa by the end of 2012. These issues and more, will be address at the LTE Africa conference, taking place on the 16^th-17^th July 2013 in Cape Town, South Africa.

3. TD-LTE: Big in China

China was well known for furrowing its own path for 3G, using the TD-SCDMA standard so it would not have to be beholden to western technology standards. It’s sticking with TD for 4G, but crucially it looks as though this Time Division thing is going to be pretty popular worldwide. Sprint in the US is using it, as it P1 is Malaysia and of course as the world’s largest operator in terms of subscribers, anything the China Mobile uses it going to have a huge impact of economies of scale. With well over a 100 TD-LTE at the moment 2013 could be a breakthrough year for TD-LTE.

4. VoLTE: Only fools rush in

Using Circuit switched Fallback for voice calls when you have an LTE network is horrible from a technical purist viewpoint, but with no negative customer feedback operators are not going to hurry to introduce new technology. Just ask Verizon Wireless and EE, who have already announced that they are pushing out their timelines for the commercial deployment of VoLTE. SK Telecom and Metro PCS may have deployed but we don’t see many joining them in 2013. To quote Mark Newman, Chief Research Officer at Informa Telecoms & Media, “A business case that looks to be based solely on spectrum efficiency will struggle to gain enough executive support to justify a rushed investment plan”.

5. LTE Small-Cell Backhaul:

Some comment from wireless infrastructure vendor Ruckus Wireless summed this up well with the following comment:

The launch of commercial 4G services from EE in October saw the UK join the LTE race. In order to achieve the network capacity required by increasing mobile data traffic, it will be necessary to augment these LTE macrocell build-outs with an underlay of small cells. This represents a new, and very significant, backhaul challenge because the mounting locations for these small cells (typically street lamps and traffic signals) are not a natural fit for fibre or microwave backhaul solutions. The optimum solution to this challenge is to use Wi-Fi in the 5GHz band to backhaul this traffic to a place where Ethernet is available. We will see lots of activity here as small cells are integrated in Wi-Fi APs, so that one unit can provide both small cells access and Wi-Fi backhaul.

LTE Tips for Beginners

LTE is a new technology that allows you to enjoy very high speed of sending and receiving data wirelessly. To receive LTE via a laptop, a tablet or PC at home, you need a separate receiver, called a radio modem.

This can be a LTE surf stick, a LTE Router or be a different modem. In some tablets, LTE Modems are already built into the units. In most of countries, including Germany, Austria, Sweden and Norway, LTE is not yet used for phone calls, but only for a fast Internet connection. Telephoning with LTE is technically possible now. It will work as telephone calls over the internet, in technical English Voice over IP or VoIP for short call.

LTE Brings Benefits to You

First, if you live in the countryside and currently do not have fast internet connection via a cable—television cable or DSL, then LTE are the best solution for you. However, the price-performance ratio is not as good as a DSL connection. On the other hand, if you live really far out, then to rent will cost very likely much less.

If you live in a big city and you regularly need large amounts of data of both send and receive, then LTE is a good idea. In comparison with current DSL connection, the LTE speed is the the fastest mobile technology available and much faster than DSL. If you ever, for example, as a press photographer sent photos, which can need a such connection.

Finally, due to low response time of the network, colloquially called ping, LTE is a good solution for some special functions: video telephony or online games work with this data radio technology very well.

Purchase of LTE-Enabled Devices

Currently, the LTE tariffs are offered with devices that LTE Mobile operators selling bundled with the tariff for almost all the network providers. 4GLTEMall.com provides unlocked LTE-enabled gadgets to help users freely choose the operators they want and no contract, no tariff.

If you don’t know how to choose, you can check our previous blog how to choose a 4G LTE USB Modem.

LTE Reception-Need Two MIMO antennas

For LTE, the data come from the air via radio. This is good if you sit in the park in the summer and with a laptop surfing. But the new redio technology subject to the laws of physicas.

The reception inside building tends to be worse than the outdoor reception. This is shown by a glance at the map of Vodafone for LTE availability. There is difference between areas where you can go with LTE inside buildings to the Internet (indoor) and areas where there is only outside of buildings receiving a sufficiently strong there (outdoor).

We give you a few tips on how to speed up your wireless data, no matter if you live in an area where Vodafone is available indoors or in some place where LTE is available out.

LTE inside buildings

Even those who LTE users within buildings, can do one or the other in order to improve the reception. Walls can generally weaken the reception of mobile signals, particularly buildings that has been processed in some way reinforced concrete, here are real killjoys.

Simply, the receiving device in a window on, preferably at a window, which lie in the direction of the nearest transmission LTE tower where in your area mobile phone masts are, you can see it. You can also ask your LTE vendors are radioed from which transmission tower from you.

LTE outside buildings

Is there only LTE outside of buildings, you do not surf, shivering in long winter nights in snow and ice: here to help you perhaps an outdoor antenna. Such antennas are in free trade to buy, offer as a complete solution with everything you need to connect. Thus it comes to be a double antenna cables and connectors. If you a great handy man, who always puts together everything yourself. For LTE, you need a pair of antennas or a dual-antenna for wireless technology, they sends and receives simultaneously.

ZTE MF823 4G LTE Datacard- World’s Smallest 4G USB Surfstick

ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly traded, global provider of telecommunications equipment, network solutions and mobile devices, announced the market launch of the ZTE MF823 known, the smallest 4G LTE data card in the world.

With its driver-less functionality ZTE MF823 4G LTE Datacard offers consumers a quick and easy internet access. It uses Qualcomm’s LTE chip platform of the second generation and has a thickness of only 13mm, which is nearly a third of the size of LTE data cards and the first generation makes it the smallest LTE map of the world.

The MF823 works with Web UI, supports IPv6 and is compatible with all major operating systems and Win8/XP/Mac. Since they LTE FDD DL / UL 100/50Mbps and UMTS HSPA +: support DL / UL 42/5.76Mbps and backward compatible with GPRS / GSM, it offers users wherever they are, high-speed access to the Internet without landline or public hotspot.

Moreover, it is succeeded ZTE, reduce the power consumption in comparison with the MF823 LTE cards of the first generation by a third. Their emission properties were improved and because it has the industry’s lowest operating temperature, it heats itself not on prolonged use.

The MF823 has been in terms of high bandwidth, low latency and high communication rates optimized (the failure rate of the data and to reduce voice transmission), so that users can enjoy a new generation of mobile internet access with high bandwidth.

The ZTE MF823 is already available in Kazakhstan and will soon arrive in Europe and Asia-Pacific countries to the market.

Since 2008, ZTE has focused its research and development and investments on its LTE products and received several core technology patents for LTE devices. This year brought the ZTE MF820S2 the world’s first multi-standard USB modem and to the MF91S the first UFI device in the world to market. In addition, ZTE was the first Chinese manufacturer to introduce a 4G LTE smartphone, the Grand X LTE (T82). Among global telecom vendors ZTE currently has seven per cent of the basic patents for 4G LTE.

What is Surfstick?

If you’re traveling with your laptop and any e-mails, send files online, or would like to work can do so with a so-called surf stick.

A surf stick is also called Webstick, can be thought of as a small “mobile modem”. Installation is straightforward, usually just plugging the stick into the USB port of the laptop is sufficient for operation.

Surfsticks work on existing wireless networks of mobile operators. When registering, you will hold the stick from the well known mobile phone SIM card. Making telephone calls over the surf stick is not possible for most providers.

When selecting the appropriate Surfstick Tariff, you should consider how often you’ll use the Surfstick month and for how long you plan to use the surf sticks. Fall in many Surfstick providers in addition to the
Fees for the operation of surfsticks even for one-off costs of the acquisition and installation of the surf sticks to.
