To give up or stick? 4G era of WiMAX will face competition in LTE

LTE commercial catch up by the end of 2009 the last train, which makes the two with the WiMAX technology, bayonet charge seems to be inevitable. Many analysts have forecast that this year will be the cut and thrust of the two quasi-4G technology, the beginning. Compared to the many supporters, LTE, WiMAX's advantage is no doubt in his last start. Prior to the United States the world's largest WiMAX operator Clearwire CEO BarryWest once expressed this view. He also believes that, WiMAX in the development of the process has been continuously introduce new and LTE technology is not new at all this.

But recently, a number of vendors for the latest WiMAX initiatives seemed to have shaken the above this view. In recent days, Cisco to 2.9 billion U.S. dollars in the acquisition of Starent Networks, the WiMAX access network is planning to withdraw from business. Analysts said the move was not surprising. In accordance with Starnet network point of view, 4G wireless competition in the future of WiMAX technology, LTE, while the United States some of the largest operators, including Verizon and AT & T have announced plans to migrate to LTE. It is now clear that mobile operators are planning to deploy LTE, Visant Strategies, chief analyst at LaurenceSwasey said. For mobile WiMAX is, there are no economies of scale. Mobile WiMAX has never been as many people think the real market. Cisco has done nothing but uphold the development of the market oriented.

However, it was, as always, remain optimistic on the WiMAX technology, Intel WiMAX Program Office, vice president and director of RamaShukla recently made it clear that Intel is expected to begin deploying by 2012, the next step will be focused on the introduction of mobile WiMAX wireless broadband technology. Intel, the world's Internet users to provide mobile WiMAX wireless broadband services, a major supporter. In their view, the new mobile WiMAX standard 802.16m will replace the 802.16e standard, can provide faster download and upload speed, to provide users with download speeds of 170Mbps and 90Mbps of upload speed, they can also fully backward compatible with 802.16 e standard. Shukla expects this year's global WiMAX subscribers will reach 6000000-10000000, especially in the United States, Russia and Japan, most users, the majority of these users will start using laptops to the use of mobile WiMAX services. He said: We see that in this year's notebook computers, WiMAX applications, the rapid growth rate. 802.16d prior version of WiMAX technology, and can not be called mobile WiMAX technology, because this technology is only for stationary products which are not in the mobile state of the products, such as smart phones and fast-moving train on the use of notebook computers.

Of course, with Intel, so stand on the same camp, analysts also said that the current voice-LTE standards are still evolving, but also the lack of terminal support - multi-mode terminal for at least the second quarter of 2010 in order to be used, LTE mobile phones also have to wait before being released in 2011, these LTE network in the next period of time can only carry data services.

In addition, despite the theoretical LTE-speed Internet access over 100Mbps, the actual use of the user, because multiple users share the bandwidth, it is difficult to achieve at every turn down the rate of tens of Mbps. VerizonWireless had given expectations are, LTE speed downlink speeds for each user an average of 5Mbps to 12Mbps, upstream rate of 2Mbps to 5Mbps. Ovum principal analyst, senior analyst StevenHartley and co-author JulienGrivolas once said that LTE market will not want to re-take the 3G launch failure of the original path.
