Product Overview Conclusion
SeaSolve Software Inc., www.seasolve.com
IEEE 802.16-2004 standard for fixed broadband wireless access (FBWA)
256-carrier OFDM; bandwidths 1.25 to 20 MHz; carrier frequencies up to 11 GHz
High data rates with wireless metropolitan area coverage
Deployed in TDD, FDD, or H-FDD configurations
Base Stations (BS) and Subscriber Stations (SS) in PMP configuration
TDD : BS and SS transmit at the same carrier frequency but at different timeFDD: BS and SS transmit on different carrier frequencies at the same timeH-FDD : BS and SS transmit at the same carrier frequency but one at a time
