Technology Overview
StreamStar4 is packed with innovative technology that offers many advantages to operators in terms or range (coverage), capacity, efficiency and services.
- Smart Antennas (Beamforming)
Intelligent signal processing shapes the radio beam towards the receiver, thus significantly improving downlink and uplink gain and thus range and capacity.
- Hybrid CDMA + OFDMA Air Interface
Advanced, ITU-standard Air Interface technology that combines the unique properties of CDMA and OFDMA offering superior spectral efficiency.
- Superior Voice Support
Built-in optimized digital voice provides a highly efficient voice subsystem that needs no 3rd party ATA devices or softswitches.
- Seamless Mobility
Full voice and data handoff from cell to cell with packet loss and no call drops at up to 150 Km/H.
- High Capacity
High spectral efficiency is assured with CDMA spreading, fine-grain OFDMA resouce allocation, adaptive modulation, and high beamforming gain.
