is available from Novatel wireless and a sample is shown below.
The EU860D/870D and E725 conducted Sensitivity typical of factory production units will be
made available from Novatel Wireless. Although the data cards operate in Packet switched mode
the values used for estimation are from Circuit Switched mode of operation as this is the mode
the TIS is measured. The results are typically compared against carrier requirements to estimate
compliance margin.

TRP (Total Radiated Power) Requirements
Good radiated performance is critical to the effective operation of a mobile in networks. A
comprehensive characterizing of radiated performance enables carriers to know how well mobiles
work within the specific network design constraints.

Tests shall be carried out for three different frequency pairs across the bands supported by the
device, as defined for CDMA TIA/EIA-98-D and for GSM 1900 3GPP TS 51.010 in the tables

GSM-1900 Test Frequencies
Radiated power measurements will be recorded in the “free-space” configuration on all applicable
frequencies. For portable units, TPR measurements are repeated on all applicable frequencies.

to provide a first pass guideline for antenna loss planning. It is not to be a substitute for detailed design activity. Additional
losses, efficiency considerations and other system affects will modify the actual resulting TIS and as such results will
deviate from the TIS calculator shown above. Updates to TIS limits are not controlled in this document.
