Highlights of the products are:
protection class IP65,
active and passive monitoring of process-critical clients,
power supply by practically all power sources available in the industrial environments,
redundant power supplies,
a QoS implementation to guaranty real-time communication of connected clients,
features to configure and monitor arbitrary wireless network structures,
redundant wireless connections with extremely fast recovery times.
In particular, the Dual Access Point W788-2PRO, from the examined device family, offers with its second radio interface even more possible applications. Thus, two very interesting developments allow the construction of redundant and fail-save wireless networks. First, Access Points can be connected by so-called WDS links (Wireless Distribution System) almost arbitrarily on radio; and second, each two of these Dual Access Points permit the definition of parallel, redundant radio links. Therefore, WDS links allow alternative uplinks and a redundant infrastructure for the clients. With the parallel radio links you can construct fail-safe wireless uplinks between two Dual Access Points in different frequency bands.
