Fixed wireless connection is a method of transmitting high-speed data traffic over a wireless connection between two fixed points. Subscriber service consists of a microwave antenna and a radio on the customer’s rooftop to transmit and receive RF signals. The customer’s antenna is pointed at the service provider’s RF transceiver (access point) located in the radio tower or in a tall building. The fixed wireless connection to the client has a clear line of sight (LOS) to the access point that can reach a distance of up to 50 miles and a data rate of up to hundreds of Mbps.
Fixed Wireless has two settings, point-to-point (PtP) or point-to-multipoint (PtMP). The PtP network connects two locations by using two radios and two antennas dedicated only to each other. PtMP network refers to communications between an access point and multiple client radios. The fixed wireless connection can use the frequency in a licensed band or in an unlicensed band. The 900MHz (902-928), 2.4GHz, 5.3GHz, 5.4GHz, 5.8GHz, 24GHz, and 60GHz band frequencies are exempt from the FCC license requirement. Unlicensed wireless systems, while rapidly deployed, do not promise exclusive use of the band and are susceptible to potential interference. Licensed microwave wireless systems operate within parts of the radio spectrum (VHF, 900MHz, 2GHz, 3.65GHz, 4.9GHz, 6GHz, 7GHz, 11GHz, 13GHz, 18GHz, 23GHz, and 80GHz) designated by the FCC. To operate a licensed microwave fixed wireless radio system, you must apply for a license from the FCC. Licensed operators are allowed exclusive use of part of the band in an assigned geographic area.
Fixed wireless broadband is designed to emulate the coaxial cable connection and to support TDM and packet traffic such as T1, T3, frame relay, Ethernet, and ATM. Carrier-grade high-capacity wireless backhaul radio combines TDM with Ethernet to provide a seamless evolution to advanced packet-based radio performance and facilitate cost-effective and risk-free migration to IP / Ethernet. Enhanced fixed wireless technology can deliver Internet, voice, and MPLS, all with guaranteed service level agreements. The advantages of the fixed wireless connection include lower costs, greater flexibility and a faster implementation. Reliability is on par with wired networks and can be designed to achieve 99.999% availability. Service operators do their best to ensure secure data transmission by using high-gain directional antennas that precisely focus the signal and precisely direct it to the customer’s CPE. Fixed wireless broadband transmits and receives encrypted signals from specific and authenticated devices only. It uses the Advanced Encryption Standard (AES), which is the standard adopted by the US government to protect your data. Therefore, fixed wireless data transmission using AES is as secure as any transmission in the world.
The latest technological innovation has made fixed wireless technology a competitive mode of broadband delivery in increasingly high-density environments such as suburban, urban and business customers. MIMO or Multiple Input Multiple Output technology has enabled rapid growth in bandwidth capacity by continuously improving spectrum efficiency with the addition of more and more MIMO streams and smart antenna array technologies. Antenna beamforming is a crucial technology that allows the spectrum used by an access point to be reused by multiple clients simultaneously. Beamforming uses accurate aggregated information from each wireless client to focus the wireless antenna transmission signals to each unique client, achieving improved focused wireless signals and significantly reducing spectrum interference. Because beamforming isolates client signals, it creates spatial opportunities in the spectrum for additional MIMO streams to be used simultaneously using SDMA (spatial division multiple access). This is called multi-user MIMO (MU-). When downstream traffic arrives for multiple clients, the access point identifies geolocation-based beamforming opportunities to serve those clients simultaneously, dramatically improving the capacity of the radios. MU-MINO enables fixed wireless to deliver fiber-like broadband connectivity at a fraction of the cost of traditional fixed line solutions, in any environment from low-density rural broadband to high-capacity, high-capacity business connectivity. reliability for the company.
