Sending and receiving OSC over WIFI is supported by Hog 4 OS through the use of 3rd party wireless routers, however, High End Systems does not recommend using OSC over Wifi for critical show tasks for several reasons:
Reliability : Some mobile OSC software applications such as TouchOSC only support UDP (User Datagram Protocol) communications which do not include error-checking. This means that Hog 4 OS cannot verifiy that OSC messages sent by the console will be received by mobile clients and vice-versa.
Interference: Wireless routers that operate in the 2.4 GHz radio spectrum are subject to large amounts of interference due to the popularity of the 2.4 GHz radio band for consumer-grade wireless devices. Other electronics such as microaves are know to emit interference in the 2.4 GHz band. The spacing of the communication channels used within the 2.4 GHz spectrum is also narrow. Therefore, in cases where OSC over Wifi is to be used, High End Systems recommends only using wireless routers and mobile devices that support 5 GHz radio transmission using the 802.11 AC Wireless specification.
Multi-Cast Routing: The HogNet network (in which the OSC messages are integrated) utilizes multi-cast network traffic for communication between consoles and DPs which can present a challenge to the processors housed in low cost wireless routers.
High End Systems cannot guarantee the performance of UDP based wireless OSC messaging systems. All Wifi based OSC setups should be well-tested before being trusted for live show operation.
