Fixed WiMAX SoC and RF Module - 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...."

Fujitsu MB86K71 RF Module

This new RF module from Fujitsu, the world's smallest to feature all of the RF circuits necessary for Mobile WiMAX devices including RF-IC, antenna switches, a power amplifier, filters, and an oscillator circuit......

 Fujitsu MB86K71 RF Module

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.

Specifications Include
  • Module Size: 15mm x 15mm x 1.5mm 
  • Operating Voltage: 1.2V/2.925V/3.3V (3 voltages) 
  • RF band: 2.496GHz - 2.69GHz 
  • Bandwidth: 5MHz, 10MHz 
  • Wireless Access Method: 512/1024 FFT  OFDMA
  • Transmission Standard: IEEE 802.16e-2005

Personal Telco Project - Oregon

The Personal Telco Project is a 501(c)(3) non-profit organization located in Portland, Oregon dedicated to the idea that users have a central role in how their communications networks are operated.

"We are a volunteer group of Portlanders who believe that 802.11 (wireless networking, or Wi-Fi) technology is both cool and empowering. "

Personal Telco Project - Oregon

"We started, in 2000, by turning our own houses and apartments into wireless hotspots (also referred to as "nodes"), and then set about building these nodes in public locations such as parks and coffee shops. Currently we have over 100 active nodes, and we eventually would like to cover the entire city of Portland, Oregon with even more."
