These devices offer a mesh network system that allows any user to flexibly and effortlessly set up a WLAN infrastructure. Several WLAN converters create a cost-effective and fail-safe WLAN infrastructure according to IEEE802.11s and the 802.11 a/b/g/n standard after an automatic setup at the press of a button. With this network bridge, users can connect to WLAN environments e. g. in offices, healthcare facilities and industrial facilities where the Internet of Things (IoT) or Information and Communication Technology (ICT) is already being used actively and wirelessly to transmit data.
