Fixed WiMAX SoC MB87M3550 – Fujitsu

“This SoC is designed to support frequencies ranging from 2 to11GHz in both licensed and unlicensed bands. Fujitsu’s WiMAX SoC is fully compliant with the IEEE 802.16-2004 WiMAX standard….”

“The Fujitsu WiMAX SoC, MB87M3400, fully complies with the IEEE 802.16-2004 standard using an OFDM PHY. The SoC can operate in TDD or FDD modes and supports all the available channel bandwidths from 1.75MHz up to 20MHz bandwidths. A programmable frequency selection generates the sample clock for any desired bandwidth. When applying 64QAM modulation in a 20MHz channel and using all 192 sub-carriers, the chip can sustain up to 100Mbps peak raw data speed. Uplink subchannelization is supported as defined in the standard.”

Geographic Information Systems – FCC

“With these data sets, you will be able to determine the locations and limited technical details of existing towers the FCC collects data on (i.e. Cellular, Paging, Microwave, AM, FM, etc…). This information can be extremely helpful in conducting analysis such as; current service deployment, need/feasibility determinations of new services, co-location of antenna structures, inventorying of structures, network planning, etc…”
