Cellular Coverage
The Em50G requires GSM/GPRS cellular service to upload measure-
ment data to Decagon Data Service. In the USA, the Em50G with
the 2G modem operates on the T-Mobile network and is not compat-
ible with the Verizon, AT&T, or Sprint networks. The Em50G with
the 3G modem operates on the T-Mobile & AT&T networks and is
not compatible with the Verizon or Sprint networks. Please contact
Decagon for specific questions regarding 2G versus 3G modules in
the Em50G. Outside of the USA, the Em50G should be compatible
with technology used by most cellular carriers.
ECH20 Utility offers a “Communication Test” feature that allows
you to evaluate the quality of the cellular network coverage where
you plan to install the Em50G. This allows you to evaluate the cellu-
lar coverage before installing your logger. Repositioning your logger
a short distance may improve your cellular coverage.
For measurement site planning, it may also be useful to consult
the network coverage tools offered by each carrier. Please contact
Decagon for specific questions about the cellular coverage offered by
our partner networks.
