 devices. This release of WiMAX supports approximately the same speeds as the current release (Release 8) of LTE. Although the air interface is imple- mented differently, the core networks of each use standard IP-based devices. In Janu- ary 2011, the Taiwanese state-run Industrial Technology Research Institute stated that it expects Taiwanese manufacturers to have 100Mbps 4G WiMAX equipment based on 802.16m ready for the marketplace by 2012. This is earlier-than-expected availability for LTE-Advanced gear. WiMAX: Available Earlier Than LTE, Fewer Deployments KT Corporation (formerly Korea Telecom) implemented the first mobile WiMAX net- work in 2006, three years before the first LTE networks were installed in Sweden and Norway at the end of 2009. To date, there are many more subscribers on LTE networks than on WiMAX-equipped networks, and that growth is expected to continue. This is due to the fact that the organizations supporting GSM standards-GSMA and 3GPP- decided on LTE as their 4G standard. Thus, most carriers already using GSM protocols are continuing to evolve along the path outlined by 3GPP for LTE. In the United States, Clearwire offered mobile WiMAX services at the end of 2008. Prior to 2008, the Clearwire network supported only fixed broadband. Fixed broadband wireless services only support Internet access at a single location. With fixed wireless, customers can't use the service when they're away from their home or work. Sprint Nextel offers pre-4G mobile services on the Clearwire network. The mobile service is used from a fixed site for Internet access as well as anywhere else in the Clearwire network. Mobile and Wi-Fi Networks Clearwire had hoped to attract Verizon and AT&T customers by building its own high-speed mobile data network before other mobile carriers. However, the specter of competition from Clearwire spurred Verizon Wireless and AT&T Mobility to expe- dite their LTE network deployments. Clearwire has announced that, in the future, it too will implement TD-LTE service. Russian WiMAX ope
