Now that LTE and WiMax 4 G are not officially, use of which strongly promoted term is a free-for-all--at least until the time comes to Wednesday, the name of the next wave of mobile networks. T-Mobile USAlaunched an advertising campaign for a "service of 4 G" running on its network + HSPA (high-speed packet access). The move ruffled feathers between some industry observers because HSPA + is a service update T-Mobile 3 G, rather than a new technology. "I'm afraid that carriers desperate for the upside will 4 G a technical term without meaning," Gartner analyst Ken Dulaney said in an e-mail interview. "All means is that it is faster than the last network were". But new marketing push T-Mobile--had previously announced "4 G speeds"--came just weeks after the International Telecommunication Union left all current networks outside his official definition of 4 G. Unique technologies that qualify as 4 G are a future version of LTE (long-term evolution), called LTE-advanced and the next generation of WiMax, officially known as IEEE 802.16 m or WirelessMAN-Advanced, according to the ITU radiocommunication sector. None of these is expected to go live commercially until 2014 or 2015, why the ITU has said its target for 4 G is a speed of 100 M bps (bits per second) downstream with high mobility and 1 G bps, with limited mobility. So LTE and WiMAX, which was advertised as 4 G for years, have no complaint about the war of words either. The title over 4 G is nothing new. Before there was a technical definition by ITU or omnipresent advertising by the carriers, there were licensing requirements of spectrum by national Governments. Some blocks of frequencies auctioned or assigned in recent years have come with a requirement that they be used for next-generation mobile networks instead of 3 G, said research analyst Phil Marshall Tolaga. This was one of the reasons that funders of WiMax fought hard to ensure that their technology was defined as something new. The battle for using 4 G seems to be more heated in the United States, said Marshall, based in Boston. Most carriers in Europe are following the same path well-defined from HSPA to LTE, while in Asia, WiMAX and LTE abruptly have pointed outside the territory of 4 G. In many developing countries, these two technologies are deployed primarily to residential broadband, he said. Both WiMAX and LTE are truly a new type of network and are similar to one another. Both are Internet Protocol (IP) networks, from one end to another, and both use a technology called OFDMA (Orthogonal Frequency Division Multiplexing Access). Moreover, each has a migration path to a future with super-fast networks which will be officially 4 G, Marshall said. T-Mobile said works with ITU on its future standards, but stresses that these technologies 4 G officers are not yet in the real world. "It is all conjecture," said Mark McDiarmid, senior director of engineering at T-Mobile. "For us, 4 G is really about the consumer experience." "What we are selling today ... is clearly the equivalent or better than that is marketed today as 4 G," McDiarmid said. The HSPA + network provides on average 5 bps downstream for Smartphone M and 12 M bps for laptop dongles, said McDiarmid. By comparison, Clearwire cites the average speed of 3 M bps at 6 M bps for its WiMAX network, which is also sold by Sprint Nextel and Verizon Wireless says its LTE network series to launch later this year showed the speed of 5 M bps to 12 M bps. Sense for t-mobile to pick up the term widely used, said analyst Peter Jarich of Current Analysis. "If I am in a market where everyone else is calling their stuff 4 G and I believe that my services (is) going comparable, then what kind of duty my shareholders ... call me 4 G," said Jarich. These broad uses the term "4 G" aren't likely to harm consumers, analysts said. Networks and devices offer the promise or not, and the Subscriber must be upgraded before exploiting anyway any migration path of the network, they said. "What we are talking about is a piece of the puzzle," said Yankee Group analyst Chris Nicoll. "Is actually the device that has a huge impact on the perception of network users and their user experience." In a survey of Yankee, AT&T users with Apple iPhone 3 G rated network carrier higher than those with less advanced feature phones, said. because the industry is essentially defined 4 G per se, throwing the terminology around might not even be confusing to consumers, Marshall of Tolaga said. "Since we have already created an expectation of a certain level of performance as qualification for 4 G, then maybe it isn't so, "said Marshall transaction.However, today 4 G credits may return to haunt mobile operators along the way, he said. The industry is doing the same thing with 4 G who made with 3 G in the first part of the last decade. First data mobile technologies like CDMA2000-1 x and edge (Enhanced Data Rates for GSM Evolution) were classified 3 G, just to get demoted a few years later, when the real 3 G systems, EV-do (Evolution-data optimized) and UMTS (Universal Mobile Telecommunications System) have been deployed, he said. Previous networks typically are now calls 2,5 or 2 g .so when it comes time to roll out LTE-advanced and WirelessMAN-advanced, what has proudly called 4 G today can get a new name. Are always kind of always ahead a bit, "said Marshall.
