37.508 is an ITU-T standard that defines the specifications for multiple-input multiple-output (MIMO) wireless communication systems. MIMO is an advanced technology that enables higher data rates, extended range, and greater reliability in wireless networking by combining multiple antennas and radio frequency (RF) signals. In this article, we will discuss the application field and working principle of 37.508.

The 37.508 standard is mainly used in wireless local area networks (WLANs). It enables the introduction of higher data rates up to 6.9 Gbps and extended range capabilities, making WLANs more suitable for next-generation applications. The new technology also enables longer distances between clients and access points, which in turn reduces the need for additional access points and resulting in fewer points of failure for the WLAN. Additionally, the increased spectral efficiency of 37.508 reduces the risk of interference from other wireless networks in the surrounding area.

The working principle of 37.508 involves the use of multiple antennas and multiple RF signals. A combination of antennas and RF signals is referred to as a MIMO system. The system transmits multiple signals with each signal sent from a different antenna, which helps to reduce errors and detect signals more accurately. The received data is combined into a single up-stream or down-stream signal, allowing for higher data rates. Additionally, the multiple antennas and signals also provide increased signal robustness, allowing for a greater level of reliability than seen with a single antenna system.

37.508 also provides increased security for WLANs by enabling smarter communication between the access point and any associated devices. It helps to ensure that only known devices are able to communicate with the access point and that each transmission is secured with advanced encryption. Furthermore, it enables the implementation of stronger authentication protocols such as EAP-SIM and EAP-AKA.

In summary, the 37.508 standard is used in WLANs to enable higher data rates and extended range capabilities. It works by combining multiple antennas and RF signals into a MIMO system, which allows for increased spectral efficiency and robustness. The increased security it provides makes it suitable for next-generation applications. The combination of these features makes 37.508 an important element for any modern wireless network.
