Digital Electronic Message Service
The Digital Electronic Message Service is a two-way wireless radio service
for passing of message and facsimile data using the 10.6 and 24 GHz band. As of 1997, Associated Communications was expected to use the band to create a network in 31 U.S. cities.
In October 2005, the FCC moved part of the DEMS service from the 18/19 GHz band to 24 GHz.
