Introduction to 2T2R and 4T4R
2T2R and 4T4R are wireless communication technologies that use multiple transmit and receive antennas to improve the performance of wireless networks. The numbers 2T2R and 4T4R refer to the number of transmit (T) and receive (R) antennas used in the system. For example, a 2T2R system uses two transmit antennas and two receive antennas, while a 4T4R system uses four transmit antennas and four receive antennas.
How 2T2R and 4T4R Work
2T2R and 4T4R systems use a technology called Multiple Input Multiple Output (MIMO) to improve wireless communication. MIMO uses multiple antennas to transmit and receive data, allowing for multiple data streams to be transmitted simultaneously. This increases the overall data throughput and improves the reliability of the wireless connection.
In a 2T2R system, the two transmit antennas transmit two separate data streams, which are then received by the two receive antennas. The receive antennas use a technique called spatial multiplexing to separate the two data streams and combine them into a single data stream. This allows for a significant increase in data throughput, with 2T2R systems capable of achieving speeds of up to 600 Mbps.
4T4R systems take this technology to the next level, using four transmit antennas and four receive antennas to transmit and receive four separate data streams. This allows for even faster data speeds, with 4T4R systems capable of achieving speeds of up to 1.3 Gbps.
