These tables are for reference only and are to be used as a guide.
Table 5 – The power density calculations for standalone transmitters at an exposure separation
distance of 20 cm are shown in table 5 with the declared transmit power and antenna gain values.
The calculations are based on a cable loss of 0 dBi. The collocated transmitter values represent
worst-case transmit power and antenna gains allowable for use with the E371 WWAN module.
For frequency dependent limits, the lowest transmitter frequency was used to represent the
lowest MPE limit (e.g. 706.5MHz = 0.4717mW/cm
2
). The WLAN power levels listed represent the
worst-case values for the corresponding frequency ranges.
Table 6 - Based on the WWAN MPE calculations in table 5 this table provides guidance on the
collocated power density with the various WWAN modems in the 700MHz band of the E371.
Table 7 - Based on the references in table 5, this table provides guidance on the collocated
power density with the various WWAN modems in the 850MHz band of the E371.
Table 8 - Based on the references in table 5, this table provides guidance on the collocated
power density with the various WWAN modems in the 1700MHz band of the E371.
Table 9 - Based on the references in table 5, this table provides guidance on the collocated
power density with the various WWAN modems in the 1900MHz band of the E371.
