Channel 70 is Licence free
Wireless Microphones can tune into frequencies that do not require a licence to operate. There are several licence exempt areas for PMSE use. (Programme Making and Special Events)
The UHF licence exempt range is 863.100-864.900 MHz. This is within Channel 70 which has little spectrum assigned to it so limiting the number of users to four. The power is limited by legislation to 10mWatt. There is no limitation to how many frequencies can used in this channel as long as users stay within the confines of the band. More users could be squeezed in but that would jeopardise clear reception and interference from adjacent channels.
There are currently no plans to remove access to Channel 70; it will continue to be licence exempt for PMSE users.
Channel 70 is adjacent to use of mobile in the 800 MHz band. There should not be any interference however this is the risk taken with the licence exempt channels.
