![]() In order to address the continuously growing wireless capacity need, the next generation LAN and WAN systems are expected to use higher frequencies referred to as millimeter wave spectrum shown in Table 1. The 4G LTE on the other hand provides wide area long-range connectivity using licensed spectrum and dedicated infrastructure such as cell towers and backhauls to connect to the Internet.Īs more people connect to the Internet, increasingly chat to friends and family, watch videos, listen to streamed music, and indulge in virtual or augmented reality experience, data traffic continues to grow at unprecedented rates. Wi-Fi operates on shared or unlicensed spectrum as short-range wireless extension of wired broadband systems. BACKGROUNDĬurrent wireless communication systems are based on two popular standards: a wide area network (WAN) standard referred to as the Fourth Generation Long Term Evolution (4G LTE) and a local area network (LAN) standard called Wi-Fi. This application relates generally to wireless communications, and more specifically to downlink and uplink data multiplexing on widely spaced frequencies in wireless broadband communication system.
