About 16. Other Wireless Networks
Beyond Wi-Fi, diverse wireless technologies address specialized ranges, power budgets, and mobility requirements unserved by LAN standards. Cellular networks (4G LTE, 5G NR) provide wide-area licensed-spectrum coverage with seamless handoff and QoS guarantees for mobile broadband, while LPWAN technologies like LoRaWAN and NB-IoT enable decade-long battery life for sparse sensor telemetry across kilometers, representing opposite ends of the wireless design spectrum.
Satellite communications cover remote oceans and rural areas inaccessible to terrestrial infrastructure, Bluetooth PANs connect peripherals with ultra-low energy consumption, and Zigbee/Thread mesh networks support smart home automation with self-healing topology. Emerging paradigms like mmWave backhaul, free-space optics, and underwater acoustic networks push wireless boundaries into new domains, demonstrating that no single technology suffices for all scenarios and ecosystem diversity remains essential for comprehensive connectivity.
