Even before its launch in 2010 or later, the fourth-generation (4G) technology Long Term Evolution (LTE) is forecast to become the choice of many network operators. LTE may have more than 32 million subscribers by 2013, according to a study from ABI Research. ABI senior analyst Nadine Manjaro attributes about 37.5 percent or 12 million of the subscribers to Asia-Pacific countries, while the remaining percentage will be split between Western Europe and North America. Telecom companies that have announced their plans of adopting 4G LTE include China Mobile, Japan’s NTT Docomo and KDDI, Vodafone and Verizon Wireless.
Mercury has presented its high-end built-in car navigation system ‘MD5000′ supporting mobile broadband Internet service. By adopting KT WiBro device, it delivers faster speed than HSDPA even while moving at a speed of up to 120 km/h.
For their next big upgrade, Aircell will be utilizing LTE 4G technology as their next-gen choice. This will greatly increase the speed of Internet access for those with wi-fi enabled devices like laptops and cell phones, making watching hi-definition movies, playing multi-player games–in-flight World of Warcraft, anyone?–sending instant messages and more, feasible.

Though 4G technical requirements do not yet exist, and no specified wireless technology actually meets such requirements, the industry refers to technologies as 4G platforms if they’re likely to be able to meet expected 4G requirements, namely extremely high throughput rates of up to 1 Gbps peak in very wide radio channels of up to 100 MHz.
Telstra and Ericsson are claiming, post-trials, that they will squeeze 21-42Mbps out of the Next-gen network next year - and all this from enhanced-HSPA?? Interestingly, ZDNet looks at the server infrastructure and software that is going in to providing these new blistering speeds - a blade cluster architecture will be used, significantly reducing the floorspace requirement by 85% - and reducing its carbon footprint by more than 60 per cent - which has got to be a good thing.
Ericsson has signed a frame agreement with Japanese operator, Softbank Mobile, to expand and upgrade its HSPA (High Speed Packet Access) network to increase capacity and enable even faster mobile broadband. With this contract, Ericsson will expand its business with Softbank by providing enhanced HSPA on new and existing base stations in the high traffic areas of Tokyo, Nagoya and Osaka.
As the wireless industry presses ahead with plans for a next-generation wireless technology, one key player keeps dragging its heels. Indeed, on April 14, several dominant wireless companies agreed to a licensing framework for patents addressing the emerging technology, known as Long Term Evolution [LTE]. The companies, including handset maker Nokia (NOK) and network equipment maker Ericsson (ERICB), join major wireless operators including Verizon Wireless and China Mobile as supporters for LTE, a technology widely seen as an on-ramp to truly speedy mobile Internet connections. If it lives up to its billing, LTE would make today’s cable and DSL modems — as well as the “3G,” or third-generation, mobile networks wireless carriers have spent billions to deploy — seem downright snail-like.
In fact there are too many radios, especially on high-end devices. And it’s only going to get worse in coming years as 4G networks using LTE or WiMAX proliferate. Sure WiMAX will begin as a data card inserted into a laptop much like my beloved 3G modem, but in time it will find itself in handheld devices including mobile phones (or so vendors tell me). Meanwhile current 3G and 2G networks will still have to be supported because carriers roll out new networks slowly. Add in radios for other wireless devices, and problems start to emerge.
Institute for Information Technology Advancement (IITA), a state agency, announced that it would embark on analysis of RFID, 4G technologies, and patents owned by local research centers, SMEs and colleges. IITA said that the work aims to help more research centers and SMEs to develop more proprietary technologies.

WHAT would the technology industry be without standards wars? Like a city without sex, some might argue. But not all fights are winner-take-all battles like the one between VHS and Betamax in videotapes, or Blu-ray and HD DVD in high-definition video discs. Sometimes there need not be a loser, and the din of battle may drown out the real issues—as in the fight between WiMAX and LTE.
