Ten Technology Predictions for 2008 What will




LTE, Mobile WiMAX UMD and seek to dominate the 4th. generation cellular

While in Argentina is still very recent debut of 3G or third generation cellular technology, which basically means broadband on mobile phones in more mature markets there is already talk of 4G and there is a heated debate about which technology will prevail in the future.

To see a bigger picture, the organization 3G Americas unites wireless operators and vendors across the continent, published a forecast of subscriptions global mobile broadband. They claim that the current 3G-2012 come 1670 million subscribers worldwide. According to this source will dominate the UMTS / HSPA, GSM evolved, with 78% of users, or 1300 million customers. Second is Ev-Do (Evolution Data-Optimized), derived from CDMA, with some 230 million subscribers. Currently, cellphone users worldwide, adding all the technologies, exceed 3.12 billion. According to Nokia will be 5 billion by 2015. But when it comes to 4G estimates are much more evanescent. Why? The analysts their arguments is that behind the estimates is a strong bid supported by marketing companies to position their standards. However, there is some consensus. The first is that competing technologies must ensure verifiable speeds of 100 megabits per second or more. Breakneck speed for a market that is just getting used to see bids of less than 10 Mbps in fixed broadband. Currently, there are three standards in terms of keeping the rod of the fourth generation of wireless broadband. One is the 3GPP LTE (Long Term Evolution), the second mobile WiMax and 3GPP2 UMB third is (Ultra Mobile Broadband).
One by one LTE (Long Term Evolution) is proposed as an enhancement of UMTS, but say that coexists well with the known standards. Is behind corporations like Nokia Siemens Networks field testing in urban areas to 173 megabits per second. Its availability is expected to be from 2010. For its part, Mobile WiMax (Worldwide Interoperability for Microwave Access) is the telecommunications technology created in 2001 by the WiMax Forum, which defined WiMax as a technology that allows the arrival of the last mile with wireless broadband and an alternative to cable or ADSL. " For mobile WiMax, also known as IEEE 802.16m, implementations may be used for both fixed and mobile services. The telephone company Sprint Nextel in the United States invested $ 5 billion to deploy its WiMax network and many corporations such as Vodafone, Intel and Telmex, who have put their chips on it. For UMB (Ultra Mobile Broadband) is a derivation of the standard known as CDMA2000. It is a system based on TCP / IP, that is, the Internet standard, and reaches speeds of 280 Mbps; say it commercially in 2009. Now it is expected that in the course of this year and next, the International Telecommunications Union (ITU) convened to all bidders to formally establish who the main players of the future of mobile phones and have the right to be considered 4G.
