4G is the latest wireless internet connection service succeeding the earlier versions of 2 and 3G, it was first launched in March 2011 and offers users improved data speeds for downloading music, video streaming and navigational directions. This cutting-edge technology incorporates sole IP-based networking systems with OFDMA digital modulation schemes, users are provided with a safe Web Protocol solution, WiMAX, which allows them to access the net from anywhere and at their own convenient time. Research shows that those who are using it via public transport systems like the bus or train experience average download speeds of 100 Mbit/Sec, whereas stationary home users enjoy faster download speeds of up to Gbit/Sec.
4G offers 10 times more advanced bandwidth than its predecessors with network capacity of around 40 MHz. With this innovative technology, one can enjoy quality video conferencing, 3D television, cloud computing, gaming services and IP telephony. When linked to modern communication devices like the Smartphone, this technology offers quality LAN roaming potential and flawless connectivity. It’s one of the reasons why most 4G phones are popularly referred to as MAGIC. An abbreviation that stands for Mobile multimedia, Anytime-anywhere, Global mobility assistance, Integrated wireless solutions, Customized mobile service. Network service providers usually have their own unique internet plans which range from 30-USD300 a month. If your job requires you to stay connected at all times then spending such an amount should not be a bother. Nonetheless, if your time online is only limited to updating social content on Facebook and Twitter then reconsider your options so as to save cash on data.
Implementation and Coverage
Since 4G technology is still new in the world of internet connection, it’s yet to attain widespread coverage from renowned service providers. Most SPs have special coverage maps which indicate regions where the service is available, this means that phones which use this technology as the primary connection network may revert back to 3G on default, especially in places not covered by the network service provider.
Types of Phones
In order to enjoy wireless 4G coverage, your smartphone needs to be optimized with advanced web technology systems. Most wireless service providers have affordable fast internet services. These companies also offer advanced phones with features like video calling, broadband net access for PCs and HD video streaming. With these additional web-services users can interact with their devices as if it were a desktop, features such as tabbed browsing, HTML email assistance and Adobe Flash are available at incredible speeds.
Since 4G offers better data transmission than its predecessors, the costs of accessing this service tends to be more. Moreover, secondary connectivity plans such as tethering may incur additional costs-this technology allows smartphone users to share their handset’s Wi-Fi data with a computer or PC.
Tips to consider when contemplating the use of 4G
Most modern smartphones offer 4G-LTE which is an advanced version of the system, some factors that may affect how the program works include:
1. Your Location
Ensure that the place you live, work or hang out has sufficient coverage, if the net is lacking or browsing restrictions are placed then it would be pointless to subscribe to this internet offer. Not all cities of the world have technology systems that support 4G, therefore if one is planning to visit such places then they wouldn’t be able to access this service. Moreover, lag may occasionally be encountered when there’s uncontrolled data transmission between 2 different network generations. Lag may also be encountered when there is data transmission between two different generations of network access, namely 3G and 4G LTE.
2. Your Usage
Though this web technology is expected to undergo major advancements in 2014, there are various other data plans that aren’t fixed to this system. One such example is the Call Drop which requires regular updating to continue operating normally; coverage gaps may as well cause major traffic communication loss. Ever since mobile phones were introduced into the market, users have continuously complained of slow speeds especially during the peak hours. It was initially thought that these problems could be solved by 3G, but experience shows that only 4G connection can salvage users from slow speeds.
How can I get a 4G connection?
Most mobile operators have a coverage checker that works based on the post code that’s been keyed in, if there’s any doubt on this particular service then call your private operator for further assistance. There are 2 types of covers that you can register for and they include the indoor and outdoor packages. If your operator doesn’t offer these services then it would be appropriate to wait till 2015, that’s when telecommunication experts believe most modern handsets shall operate on 4G.
You would also need a phone that supports advanced web features, some of the most popular brands include iPhone V, Samsung Galaxy Lite, Note and Blackberry Z10 amongst others. Nevertheless, if you already have another internet subscription plan then it would be appropriate to cancel them and get a new 4G service. Some service providers also provide weekly and monthly data plans that users can sign up to, of course based on their individual connectivity needs.
What else should I know about this technology?
Currently there are only two commercially viable 4G systems which include the standard Mobile WiMAX and first-release LTE system. Nevertheless, there has been ongoing debate on whether these preliminary versions should be ranked as internet systems or not. In the US, Sprint telecommunications has deployed cutting-edge WiMAX networks ever since 2008, while MetroPCS became the very first mobile operator to provide LTE which they have been offering since 2010. The digital equipment used to optimize band frequencies may vary from one country to another, for instance as of April 2012 WiMAX was still not available in the entire European market.
Key features of the program:
1) MIMO. This technology helps users attain ultra-high spectral efficiency since it features spatial processing capacity and multi-antenna or multi-user MIMO
2) Frequency domain equalization. It helps to exploit frequency selective virtual channel properties, for instance, OFDM and SC-FDE can be used as uplink systems. Those who use this technology would be able to exploit different frequency selective channels
3) Frequency statistical multiplexing. Features a set of powerful sub-channels that can also be used by different users based on their specific channel conditions.
4) The turbo principle of error-correcting modules can help minimize SNR at reception’s side
5) Link adaptation. It’s one of the latest net applications that allows users to enjoy error-correcting codes and adaptive modulation.
6) IP-based virtual femtocells. This is a powerful home node system that is particularly connected to fixed web broadband infrastructures for cheaper surfing experiences.
Contrary to previous generations, modern 4G systems don’t support circuit relayed telephony, moreover UMB, IEEE 802.20 and UMB may lack on the soft-handover process commonly referred to virtual cooperative relaying.
Multiplexing and Point Access schemes
Recently, new 4G access schemes including Interleaved FDMA, multicarrier CDMA, orthogonal FDMA and multicarrier CDMA. These internet systems are particularly based on FFT algorithms including frequency domain equalization, which when done correctly results to subsidized multiplication levels per second. The technology also makes use of spectrum bandwidth but in a flexible way that costs less and also improves efficiency.
Another key advantage of this technology is that it requires far less complexities during the equalization process that mainly occurs on the receiver. This is truly an added advantage especially in modern MIMO environments, this is because it uses spatial multiplexing Data transition module for advanced connectivity. Apart from the improved multiplexing systems, users would also enjoy better modulation techniques for their own convenience.
Unlike 3G which is mainly based on two analogous infrastructures consisting of cable switched and packet network nodes, the 4G coverage program is only based on packet-switching and therefore requires low latency online data transmission. When the latest smartphone network system was deployed, IPv4 was slowly adjusted and it was believed this would be final model since it packed literally all the cool aspects of modern day web connection. However, the manufactures completely went out of the way to develop another net browsing system known as IPv6. This powerful web system can support an entire family for several months without worrying about the costs of installation or any other updates that need to be categorized before data is distributed evenly across the mobile system.
Understanding MIMO and how it works
The standard performance of most radio communication systems depends on virtual antenna activity, nonetheless only 4G has the resources and willingness to display, high-rate, highly reliable long-range data communications. MIMO connectivity makes use of spatial multiplexing technology that offers great bandwidth conservation as well as maximum power efficiency, independent streams of data and rapidness in transmission. The technology has also been nicknamed as a branch of intelligent antenna, partly owing to the fact that it can multiply data rate using much smaller initial bandwidth channels.
Wireless Architecture and 4G Data defined
One of the most vital features of this program is OWA popularly known as Open Wireless Net Architecture; it helps in supporting several virtual interface connections, especially those that run on data share or communal platforms. History has it that this technology was first envisioned by DARPA institute, the establishment believed in a revolutionary peer networking system where mobile devices would work as both transceivers and routers for auxiliary devices found within the same network, thus eliminating the hub weaknesses that are often witnessed by 2G and 3G cellular protocols.
Since the advent of 2.5G GPRS modules, cellular programs have provided extensive dual infrastructures such as packet switched data service nodes and circuit voice calls. In any typical 4G system, a circuit-switch infrastructure would be required including two parallel systems where traditional voice calls are interchanged by rapid IP telephony.
Introduction of 4G Mobile in UK
EE was the first mobile operator to launch and distribute a comprehensive 4G network way back in Oct 2012. They were soon followed by Vodafone Telecommunications and 02 who both launched their data services at the end of August 2013. Three Inc. was the final company to join this party when they launched their network later on in December.
There are two advanced categories of this technology which include the 4G LTE Advanced and 4G LTE, the LTE stands for ‘Long Term Evolution’ and had its name evolve during developmental phases of modern-day technology as we know it. As the name suggests, Advanced works far much better than its counterpart though the difference is quite small. Double Speed transmissions are presently available in around 20 UK towns via EE Service Provider. The company is set to upgrade their systems later on this year to provide download speeds that are 20 times faster than your typical 3G. On a lighter note, the mobile phone operators are more likely to keep things simple by calling all their new web services 4G in a bid not to overcomplicate issues for their consumers.
Nonetheless, download speeds are not the only factors that have undergone improvements since the program also has better response time compared to its predecessors. This is made possible due to the lower ‘latency’ levels featured here. In other words, a device that’s been connected to mobile networks would get quicker responses than a similar appliance connected to 3G network. Though the advanced latency times may not seem much, a reduction rate from 120-60 milliseconds, this can particularly be important when gaming or streaming-in live video games. It constitutes for a more responsive virtual gaming environment, including an enhanced viewing experience.
Though 4g coverage is fast and more reliable, users are advised to enable their smartphones relay bundles through the phone rather than set it on data roaming mode. This allows them to save credit that could have otherwise been spent on unnecessary default background files such as email, calendar, weather and climate. Another strategy is switching off the entire data network when you are not using your phone, and only switching it on when needs be. In addition, it’s possible to change your phone’s settings from 3 to 4g and vice-versa depending on the type of files you are streaming from the net. One can as well use the traffic manager application to set a limit on the amount of data they would be expending each day. Using your smarphone to access the net can be fun but always take care not to spend too much money on data bundles. There’s no doubt that this contemporary technology has taken web surfing to a whole new level, users can now enjoy streaming their favorite online content without worrying about delays or interruptions in loading web pages.
