IP Multicast networking allows for efficiently sending a single stream, such as an MPEG-2 stream, to a large number of receivers. IP multicast is a well-established technique within wired networks (LAN), in particular for IPTV, for example distributing digital television in hotels, hospitals, cruise ships, or individual homes.

However, today's commodity devices and infrastructures for wireless networks, such as 802.11 wireless LAN (WLAN), often do not properly support multicast networking. Problems range from severe bandwidth limitations for multicast streams to complete overloading and failure of wireless networks when only transmitting a single multicast stream to a single wireless client.

The Recaster appliance by Motama overcomes these limitations by transparently re-casting multicast streams available in the wired IP network to unicast streams for wireless clients. This enables the integration of wireless clients, such as set-top boxes, laptop computers, tablet PCs, or mobile phones into the existing streaming infrastructure.

In addition - and even more importantly - the Recaster appliance allows to optimize the transmission of unicast streams to a number of wireless clients connected to a single WLAN access point (AP). Recaster 200 is a turn-key solution that allows for seamlessly increasing the number of simultaneous users in existing networks by exploiting all available bandwidth up to the limits of today's wireless networks.
