Voice and Data over one Infrastructure: Mobile Telephony over WLAN (VoWLAN)

In professional environments, laptops connected to the local network via wireless LAN are increasingly replacing stationary inflexible workstation PCs. Wireless solutions are also becoming more common in logistics centers, discounter outlets or hospitals, e.g. for mobile, touch-free data capturing or the integration of vehicles (e.g. forklifts). To avoid interferences in the radio link, it is usually necessary in industrial and logistics environments to examine network coverage in advance and to set up a wireless LAN infrastructure with a high number of access points.

This radio infrastructure is often also used for telephony. Especially in environments without DECT wireless network, major cost savings can thus be achieved. The operating costs can also be decreased because it is only necessary to administrate and maintain one wireless infrastructure.

Funkwerk offers different WLAN access points for office environments (W1002n), harsh industrial environments (WIx040n) or for outdoors (WIx065n). All access points support the WLAN standards 802.11a/b/g/h/n and are equipped with up to 4 removable antennas. Power supply via Ethernet (PoE) according to standard 802.3af is possible.

As a hybrid PBXs elmeg hybird systems can be used. As a VoWLAN telephone, we recommend the Ascom i62, which can be integrated smoothly into the Funkwerk infrastructure. Alternatively, a dual phone (GSM/ WiFi), such as an Apple iPhone can be used.

Important: Professional radio measurement ought to be performed in particular on the industrial and logistics sector. The overlapping section of the radio cells is especially important to ensure trouble-free roaming in the case of mobile WLAN clients.
