WLAN firmware with PRP technology
Belden has introduced the latest version of its WLAN firmware to manage its line of OpenBAT industrial wireless devices, The Hirschmann HiLCOS 8.9 is the first industrial wireless application of integrated Parallel Redundancy Protocol (PRP) technology, an industry standard that enables systems to overcome network failures without affecting data transmission.
Using PRP inside a wireless access point increases reliability. This is because PRP offers zero failover with two redundant networks. By doubling the packets, there is no data loss if one packet fails, as either the faster packet or the second packet gets through with a functioning second network.
The HiLCOS 8.9 firmware includes key caching which enables fast authentification between several access points in a network, known as "fast roaming". The software also offers management, redundancy and security functions.
Product Manager Pascal Unterdorfer explains: “Although relatively new, PRP technology is already used in wired applications. However, it is totally new for a wireless access point. With the use of PRP we can increase the reliability of a wireless connection and/or network significantly. In fact, tests prove that we can come close to the reliability of a wired connection.”
