In January 2011 the FCC will begin a phased migration for all wireless users in the 150-174 MHz and 450-470 MHz frequency band to narrow band (12 KHz) operation. In 2011, no new FCC licenses for wide band (25 KHz) operation will be granted and the FCC will prohibit the manufacture or importation of new equipment that operates in the 25 KHz band. On January 1, 2013 the FCC will require all radio licensees to operate only on narrow band channels. If you have a 25 KHz radio license, it will need to be modified before the January 2013 date.

All ESTeem Model 192 wireless modems ever manufactured have been compatible with the new narrow band license requirements with no hardware upgrade required. Existing networks simply require software adjustments and all future sales will be shipped with the required bandwidth pre-configured.

ESTeem wireless modem products provide a "Wireless Solution" by eliminating conventional hard wiring or leased phone lines or cellular costs. The ESTeem Model 192M comes with the industry standard RS-232C, RS-422 and RS-485 asynchronous communications ports to give the user a new dimension to "Wireless Networking". Our packet burst, narrow band, frequency agile, VHF communications products allow the user to create a "Radio Area Network" of up to 255 users on a single frequency. The packet burst communications was chosen to give the system very high data integrity in high noise industrial environments. The ESTeem incorporates forward error correction and 32 bit CRC error checking that provides received data accuracy of greater than one part in 100 million.
