Because the vast majority of all world cell phone companies are moving to LTE, thats a well known fact.

Most carriers supporting GSM or HSUPA networks can be expected to upgrade their networks to LTE at some stage:
AT&T Mobility has stated that they intend on upgrading to LTE as their 4G technology in 2011, but will introduce HSUPA and HSPA+ as bridge standards.
TeliaSonera has started network built up in Stockholm and Oslo, and will follow up in Copenhagen when a license in Denmark has been bought/granted. The networks are still only for testing. There are no indications of a public live date.
In January 2009 TeliaSonera signed a contract for an LTE network with Huawei covering Oslo, Norway. Under the agreement, Huawei will provide an end-to-end LTE solution including LTE base stations, core network and OSS (Operating Support System). The Huawei contract was cancelled in January 2010 and a new contract was signed Ericsson.
In January 2009 Ericsson and TeliaSonera announced the signing of a commercial LTE network. The roll-out of the 4G mobile broadband network will offer the highest data rates ever realized, with the best interactivity and quality. This network will cover Sweden’s capital Stockholm and the contract is Ericsson’s first for commercial deployment of LTE.
T-Mobile, Vodafone, France Télécom and Telecom Italia Mobile have also announced or talked publicly about their commitment to LTE.
In August 2009 Telefónica selected six countries to field-test LTE in the succeeding months: Spain, the United Kingdom, Germany and the Czech Republic in Europe, and Brazil and Argentina in Latin America.
On November 24th, 2009 Telecom Italia announced  the first outdoor pre-commercial experimentation in the world, deployed in Torino and totally integrated into the 2G/3G network currently in service.
The Dutch telecom provider KPN announced that it will use LTE for its 4G network.
AlMadar Aljadeed, the biggest Libyan mobile phone operator, has announced that it will be adopting the LTE technology passing straight from 2G technology to 4G.
Despite initial development of the rival UMB standard, which was designed as an upgrade path for CDMA networks, most operators of networks based upon the latter system have also announced their intent to migrate to LTE, resulting in discontinuation of UMB development.
Verizon Wireless completed its first test LTE data calls in August 2009 and plans to deploy LTE beginning in 2010 with system-wide deployment completed in 2013.
Bell Mobility has stated their intention to use LTE as a future upgrade to their HSDPA network.
Telus Mobility has announced that it will adopt LTE as its 4G wireless standard.
MetroPCS recently announced that it would be using LTE for its upcoming 4G network.
The newly formed China Telecom/China Unicom and Japan's KDDI have announced they have chosen LTE as their 4G network technology.
Some newcomers to the mobile phone market are or will be using LTE for their networks.
Cox Communications has its first tower for wireless LTE network build-out. Wireless services should launch late 2009.
The Irish telco Digiweb is currently operating a 4G service in the Dublin area.
Sprint had a major advantage with WIMAX because they had a huge head start. I haven't seen the numbers with WIMAX, but it seems the head start hasn't produced the numbers Sprint had hoped they would.
WIMAX seems like a great option for internet access as of today, in Portland they advertise WIMAX as being super fast and portable, showing commercials with internet on a train, at the park, at home, etc. When LTE hits the scene, it will be capable of the same thing, only faster. Also, every carrier in the USA, except for Sprint, will utilize LTE. There shouldn't be a place in this country where I don't have an LTE signal. Sprint chose the wrong 4G path, IMHO.
