Figure 13From: Exploiting programmable architectures for WiFi/ZigBee inter-technology cooperationPER of a ZigBee link. When both WiFi and ZigBee contend for the medium, ZigBee PER increases dramatically. Using the TDMA protocol results in ZigBee PERs similar to the non-interfered situation without decreasing the WiFi throughput, indicating a more efficient channel usage.Back to article page
