WiMAX network components The WiMAX Base Station

WiMAX network components The WiMAX Base Station Nominal power Dynamic : for power control Gain : different for the UL and the DL (sub-channelization) Losses : according to the linear loss of the cable + connector loss Radiated power Frequency : main transmitting frequency Antenna height in meters AGL or ARL Bandwidth : for the interference analysis (channel overlap) General parameters Each antenna can be configured using individual parameters

WiMAX network components The WiMAX Base Station Sectorization aspects The user has full control on the number of sectors used by the Base Station. They can be co - localized or splitted on the rooftop.

WiMAX network components The WiMAX Base Station Radiation pattern The antenna can be configured using: H and a V pattern/sector A full 3D pattern/sector A full 3D pattern per antenna (not advised for WiMAX planning purposes)

WiMAX network components Conclusion Select the best equipment according to needs and the simulation in the planning tool ! ICS telecom allows the input of individual technical parameters for the WiMAX Base Station, and the WiMAX CPE as well. It allows the simulation of different equipement manufacturers, for comparison purposes. The analysis can be performed in coverage mode, or in ponctual mode.
