Ubiquitous Broadband from Nextel.Nextel Wireless Broadband High-speed wireless transmission of data. What is "high" speed is always a changing number. Wireless systems are typically slower than land-based, wireline networks. In the past, wireless broadband started at 250 Kbps, whereas land-based broadband was generally considered to start at T1 is a new service that promises secure, IP-based broadband access over a wireless connection. Users will be able to connect from anywhere on the Nextel network at speeds of up 1.5Mbps downstream and 375Kbps upstream. Nexters broadband uses Fast Low-latency Access with Seamless Handoff Orthogonal Frequency Division Multiplexing See FDM. (communications) frequency division multiplexing - (FDM) The simultaneous transmission of multiple separate signals through a shared medium (such as a wire, optical fibre, or light beam) by modulating, at the transmitter, the separate signals into separable (FLASH-OFDM) technology from Flarion. Flarion claims FLASH OFDM (Orthogonal Frequency Division Multiplexing) A digital transmission technique that uses a large number of carriers spaced apart at slightly different frequencies. outperforms 3G connections such as EvDO, which Verizon offers in two US cities. Verizon's EvDO network promises downstream speeds of 300-500Kbps and upstream speeds of about 56Kbps. Nextel is conducting a limited trial of its service in the Raleigh/Durham/Chapel Hill area of North Carolina North Carolina, state in the SE United States. It is bordered by the Atlantic Ocean (E), South Carolina and Georgia (S), Tennessee (W), and Virginia (N). Facts and Figures Area, 52,586 sq mi (136,198 sq km). Pop. . |
