he W-CDMA format. Introductory FOMA services for a limited number of users is to begin at the end of May, with full commercial services due in October. General Packet Radio Service, a 2.5G packet switching upgrade to GSM offering theoretical data speeds of up to 115kbps; introduces the packet switched core required for UMTS; used globally in Europe and Asia, in the US by AT&T Wireless / Cingular and T-Mobile. Global Service Mobile; platforms include today's GSM, GPRS, EDGE and 3GSM; developed for operation in 900MHz band and modified for 850, 1800 and 1900MHz bands. integrated Digital Enhanced Network, technology developed by Motorola using 800, 900 or 1.5 GHz spectrum and used by Nextel. This technology will likely disappear in the next 3-4 years. Proprietary mobile data solution successfully used by NTT DoCoMo with the main advantage over WAP being that it is packet- IMODE switched network. Thus, it actually runs at the same speed of connection as WAP, but because the network is packet switched, it works considerably faster HSDPA (High Speed Downlink Packet Access) is an upgrade for WCDMA (UMTS) networks. It doubles network capacity and increases download data speeds five-fold Orthogonal Frequency Division Multiplexing, broadband wireless technology available today using. Flarion Technologies FLASH- OFDM® wireless broadband system (using 1.9 spectrum band) in trials with Nextel in U.S. and Vodafone KK in Japan. Universal Mobile Telecommunications System, supports W-CDMA radio access technology with deployments in Asia-Pacific, Europe, Middle East and Africa. Offers broadband, packet-based transmission of text, digitized voice, video, and multimedia at up to 2Mbps and offers a consistent set of services to mobile computer and phone users no matter where they are located in the world. Based on GSM, it is the next generation step for most GSM carriers around the world. Deployments for this technology started in 2004 in some countries. Cingular has announced plans to migrate its US networks to UMTS by 2006. W-CDMA
