Wireless Sensing is a new technology. It plays an important role in wireless networks, embedded systems, and other fields to make their systems smarter and more humane. It also has great commercial value. This article will briefly introduce this technology.
Wireless Sensing technology allows wireless devices and antennas to perceive the RF environment and change the frequency band as needed to avoid interference. The integrated software and hardware solutions allow wireless sensor technology to be built into enterprise-level wireless WLAN Access Points, improving security and optimizing performance.
Wireless intrusion occurs when an unauthorized WLAN user enters the network. This is caused by hackers who use a WLAN client to establish a temporary network or connect to a fraudulent access point on a wired network that lacks appropriate security levels. In either case, the key to preventing them from occurring is to take rapid defensive actions.
The first step to prevent wireless intrusion is to determine the intrusion point.
Because a WLAN uses a specific WLAN channel at runtime, it cannot detect intrusion points on other WLAN channels at the same time. It is not enough to rely on a single Wireless Access Point to provide access and security. Network administrators must be able to monitor all WLAN frequency ranges to reliably detect and determine intrusion points.
Wireless Sensing technology provides a way to monitor the RF environment in the 2.4GHz and 5GHz frequencies used by IEEE 802.11 WLAN without interrupting normal wireless VoIP and data streams. Continuous scanning of two frequency bands used by 802.11 devices and non-802.11 devices can detect intruders in a timely manner. Management personnel can take defense actions based on the detailed information of multiple wireless sensor devices in the WLAN.
Wireless sensor devices can detect non-802.11 devices.
This is important because interference can reduce the effective data throughput and overall network performance. Wireless Sensing technology allows networks to detect, identify, and circumvent these noise sources. Active behavior enables the network to be established on a more "clean" channel during initial deployment. Continuous monitoring allows network administrators to quickly correct RF noise. The result of the above measures is the optimal network performance expected by WLAN users.
