A novel ZigBee based high speed Ad Hoc communication network
Shaosheng Li, Wenze Li, Jianxun Zhu · 2009
Considering that ordinary ZigBee based systems operate at a rate of 250kbps, which imposes various limitations on their applications, and that there are 16 independent channels at 2.4GHz, this paper presents a novel approach of FPGA controlled, ZigBee protocol based multi-frequency high speed wireless Ad Hoc network. The system employed five individual ZigBee modules around a FPGA controller, merging five sub-networks into a system with higher throughput, thus reaching a maximum one-way data rate of 1Mbps, which can be dynamically assigned to up-link and down-link. This system can maintain the Ad-Hoc feature of ZigBee technology, and at the same time sustain a higher capacity. This approach may expend the application of ZigBee technology to areas in demand of higher data transmission rates.
