WiMax and LTE bring 4G generation network sooner

The 2.5G or 3G wireless communication technology is still being developed, but it has been debated about the next wave in this area when WiMax and LTE receive the backing of major telecom carriers. on the world.

Fourth-generation wireless technology is based on a network that uses a complete IP address, similar to the Internet, not depending on switching technology such as the current mobile phone network.

The 4G definition is quite ambitious with speeds from 100 megabits per second to 1 gigabit per second. However, the speed has only been achieved in a few trials, mainly in Japan, where the 3G platform has developed over the past few years. In order to fully meet this definition, it will take some years.

That does not prevent efforts to establish standards known as "4G money". They will have to demonstrate the advantages of speed, cost, companies backed . to be a big part of the 4G technology market.

The two biggest rivals on the current "ring" are WiMax and 3GPP Long Term Evolution, referred to as LTE for short.

WiMax wide area wireless network is considered to be inflated for too long without going into reality with 70 megabits per second data transfer rate. However, the technology community is hoping that 2-3 years of WiMax will appear more widely after being recognized as a global standard. Beginning later this year, mobile carrier Sprint Nextel (USA) will use WiMax for "pre-4G" networks and plan to cover up to 100 million users in 2008. Intel has long backed the platform. This with the Montevina chipset specifically captures integrated WiMax waves in its processor lines. Some computer makers like Acer, Lenovo, Asus, Matsushita have announced plans to use Intel's Centrino WiMax chip for devices.

LTE (a 3G technology with many advantages in speed) although quieter, there are many companies backed by WiMax. Currently giant mobile telecommunications companies such as Verizon Wireless, Vodafone and most recently Nokia Siemens Networks have announced plans to use LTE as the next generation wireless Internet technology. LTE developers say the technology has a download speed of 100 megabits per second, an upload of 50 megabits per second. However, like WiMax, LTE's performance slows down when it reaches further amplitudes. Despite expanding to 32 km, the optimal distance of this standard is within a radius of 4 km.

Which standard response time will be more advantageous for 4G mobile wireless communication technology. Howard Wilcox, Juniper expert, said that LTE will start to be in place from 2011 or 2012, while WiMax is also expected to grow strongly in the next 5 years.
