Fixed wireless

Article summary

. These microwave links typically carry a mix of Ethernet /IP, TDM (Nx E1) and SDH traffic to connect sites with high capacity. Such microwave links used to carry 2xE1 (4 Mbit/s) now carry 800 Mbit/s or more, using modern 1024QAM or higher modulation schemes. Fixed wireless is the operation of Wireless communication devices or systems used to connect two fixed locations (e.g., building to building or tower to building) with a radio or other wireless link, such as laser bridge. Usually, fixed wireless is part of a wireless LAN infrastructure. The purpose of a fixed wireless link is to enable data communications between the two sites or buildings. Fixed wireless data (FWD) links are often a cost-effective alternative to leasing fiber or installing cables between the buildings. The point-to-point signal transmissions occur through the air over a terrestrial microwave platform rather than through copper or optical fiber; therefore, fixed wireless does not require satellite feeds or local telephone service. The advantages of fixed wireless include the ability to connect with users in remote areas without the need for laying new cables and the capacity for broad bandwidth that is not impeded by fiber or cable capacities.…
