The fourth generation 4g mobile communications

Fourth generation wireless 4G is an abbreviation for the fourth generation of cellular wireless standards and replaces the third generation of broadband mobile communications.

The fourth generation 4g mobile communications

Comments While most of us are used to getting high speed Internet connections at home, the office or even the local coffee shop, once we are on the road those high speeds have to stay behind.

With 4G the promise is that you can get real mobile broadband to go. In this piece we are going to tell you all about the technology and its benefits, who offers it or plans to, how much it costs, and the gear you need to enjoy the next generation of wireless broadband today.

But first, some background: It's a successor to 2G and 3G wireless, whereby the first signified the shift from analog to digital transmissions, bringing data services like SMS and email to mobile phones for the first time, and the second refers to the advent of things like global roaming as well as higher data rates.

Think of wireless generations as a handful of services that get faster and more feature-rich as newer technology becomes available. With 4G you'll be able to do the same but at much faster rates, while the extra bandwidth opens the door for newer applications.

For practical reasons, we won't be dwelling on the technicalities of each term and instead will move onto the ones that involve our topic of interest here: Although no set of standards have been established as of yet by the International Telecommunication Union ITUthe authority on such things, two competing technologies have been proposed: Many service providers often use the term 4G mobile broadband to describe the technologies they are offering based on their own, sometimes distorted definitions.

Besides speed, several other guidelines have been traced for wireless communication standards to qualify as 4G. In a nutshell, they should be very spectrally efficient, should dynamically share and utilize the network resources to support more simultaneous users per cell, have smooth handovers across heterogeneous networks, offer high quality of service for next generation multimedia support, and should be based on an all-IP packet switched network.

LTE is being developed by a group of telecommunications associations known as the 3rd Generation Partnership Project, or 3GPP, as an eight release of what has been evolving since from the GSM family of standards. There are two fundamental aspects of LTE.

The first is that the technology finally leaves behind the circuit switched network of its GSM roots and moves to an all-IP flat networking architecture. This is a significant shift which in very simple terms means that LTE will treat everything it transmits, even voice, as data. The other big change relates to the use of MIMO technology, or multiple antennas at both the transmitter and receiver end to improve communication performance.

This setup can either be used to increase the throughput data rates or to reduce interference. Theoretically these can support speeds of up to 7.

Fewer cell sites have to be built and penetration into buildings is better at the MHz spectrum LTE uses. As its name suggest, WiMAX can be thought of as an extension of Wi-Fi designed to enable pervasive, high-speed mobile Internet access on a wide range of devices, from laptops to smartphones.

The current implementation is based on the Again, "theoretical" is the keyword here as WiMAX, like all wireless technologies, can either operate at higher bitrates or over longer distances but not both.

There is no uniform global licensed spectrum for WiMAX, but three have been listed: In terms of total available 4G spectrum to deploy their services, Clearwire has several times more than its competitors, which have smaller portions of the MHz band.

Some experts have said that MHz will require as few as one-quarter as many base stations to offer identical coverage to 2. As you might have guessed, the industry players behind these 4G technologies reflect the history of each standard.

Whereas LTE biggest supporters are, in general, telecommunication service companies and handset manufacturers, WiMAX counts the likes of Intel, Cisco and Google among its most important backers. It should be noted though that many companies like Nokia or Motorola are members of both industry groups, with different levels of involvement.Mobile devices are getting smaller, lighter, and more powerful; they have bigger screens and longer battery life, more features and more the rapid growth of user demands, and the limitations of third generation (3G) mobile communication systems, it is expected that fourth generation (4G) mobile systems are likely to reach the Vodafone IoT combines the world's largest mobile network, outstanding technology and a long track record of success in Internet of Things.
