BLAST System Capacity Measurements at 2.44 GHz in Suburban Outdoor Environment
01 January 2001
(PREVIOUS TITLE: Outdoor Blast Measurement System at 2.44 GHz- Calibration and Initial Results) There are ever increasing demands, in wireless communications, for additional capacity to handle voice, data and wideband Internet applications. These demands are constrained by the bandwidth that was allocated to wireless communications. The spectral efficiencies in present day wireless systems hover around 1 bits/sec/Hz. BLAST (Bell- labs Layered Space-Time) is a communication technique for achieving very high spectral efficiencies in highly scattering environments using multiple transmit and receive antennas. A measurement campaign was undertaken to assess the BLAST gains in spectral efficiency in the suburban outdoor environment for stationary subscribers.
