openfhss

We have hosted the application openfhss in order to run this application in our online workstations with Wine or directly.

Quick description about openfhss:

OpenFHSS is a community-based effort that includes schematic, eagle design files, BOM, gerbers, and firmware for a 902-928MHz ISM, 50-channel, FHSS frequency hopping spread spectrum modem.
UPDATE 2011-11-27:
The discussion forum is open to new users (OpenFHSS Website->forum)

Features:

• High Performance, Long-Range Frequency Hopping Spread Spectrum Modem
• Synchronous, Multi-Hop Repeater Chains
• Ethernet Bridge Mode
• Automatic, over-the-air firmware updates. Master updates all slaves simultaneously
• 4uA MCU initiated sleep current
• 2ppm stability for frequency and system timing reference.
• Industrial quality enclosure, connectors
• Real-Time Data Collection System with user defined scripts
• LM3S6965 32-Bit Stellaris ARM-core MCU, CC1101 transceiver, CC1190 LNA/PA
• Highly immune to multipath fading, interference
• 5mS Channel Dwell Time
• -107dBm sensitivity, 27.1dBm output power enables communications range in tens of kilometers. Depending on installation, ranges of >50km are easy to achieve
• Applications include battery-powered data collection, Low-Latency Telemetry Links (UAVs), long-range internet communications. Quality Skype phone calls have been achieved with point-to-points links.
• 230 kbps RF Data Rate
• very low phase noise performance (see emc plots in images/emc_testing)
