High Speed Multi Media (HSMM) is often referred to as being the Hinternet (Ham Internet), as it is primarily used under FCC Rules & Regulations Part 97. Under Part 97 commercial off-the-shelf equipment can be used at higher power and higher gain than the more common Part 15 802.11a/b/g operations.
The primary purpose for HSMM and Hinternet is to augment emergency communications via long range high speed wireless data networks that can handle voice, data and video communications. HSMM can also be used in the day-to-day aspects of Amateur Radio Communications.
With the rapid expansion of Asterisk PBX into the relm of radio communications the added flexibility of having a wireless linking system has also expanded.
It is now possible to have a network of repeaters and link stations that never touch a standard public switched telephone network, yet at the same time this network of repeaters and link stations has all the standard features one will expect to find with any telephone system.
By integrating HSMM along with Asterisk PBX a truly transportable network can be delivered to any location where communications is needed, with voice, data and video all being available to the agencies and organizations being supported.
