Focus on Radio Features of Alcatel A9100 WiMAX BS

Enhanced Radio Features exploitation:Orthogonal Frequency Division Multiplexing/ Scalable OFDMnumber of FFT points adapted to channel bandwidth (I.e 512 up to 5 Mhz and 1024 up to 10 Mhz)similar robustness to multi-path for higher bandwidth same coverage range (@ cell edge) when bandwidth is increased

Scalable OFD Multiple Access / Sub-channelling (several users may use different subcarriers)Adaptive Modulation & Coding (automatic selection of the best radio transmission mode according to channel quality indicators)Adaptive Antenna Technology (smart antennas to enhancecoverage and mitigate interference)
