MPE RF exposure calculations for TVG-850 EVDO with collocated
antennas

The following RF exposure calculations have been made for the TVG-850 EVDO (FCC
ID: JUP-TVG850EVDO) which incorporates the following devices and antennas:

• Sierra Wireless EVDO card, model: MC5728V FCC ID: N7N-MC5728
• Silex 802.11 b/g card, model: SX-10WAG FCC ID: N6C-SX-10WAG
• Mobile Mark antenna (cellular, GPS and 802.11) model number: SMW-UMB

This device will only be used with a separation of 20 cm or greater between the antennas
and the user or nearby person. This device will be considered as a mobile transmitter per
47 CFR 2.1091(b) and therefore has to comply with Maximum Permissible Exposure
(MPE) limits.

Limits Applicable to the TVG-850 EVDO

For mobile radio equipment operating in the cellular phone band, the lowest power
density limit is calculated using the lowest frequency as 824 MHz / 1500 = 0.55mW/c,^2
and 824 MHz / 150 = 5.5 W/m^2

For operation in the PCS band and the 2.4 GHz band, from FCC 1.1310 Table 1 (B), the
maximum values of S = 1.0 mW/cm^2 and from IC Safety Code, Section 2.2 Table 5
Column 4, S = 10W/m^2.

Co-location results for Simultaneous Operation in the Cellular Band
and 2.4 GHz band

Band Mode Separation Output Antenna Duty Cycle IC Power
Distance Power gain with (%) Density
(m) (dBm) cable loss (W/m^2)
(dBi)
850 MHz Cell 29.82 -0.25 100
2.4 GHz WLAN 16.45 1.7 100
Combined 0.20 1.93

The co-located Power Density is less than 5.5 W/m^2 which is the most stringent of the
limits for each separate transmitter (5.5 W/m^2 and 10 W/m^2 for the WAN and WLAN
respectively).

Co-located results for simultaneous operation in the PCS band and the
2.4 GHz band

Band Mode Separation Output Antenna Duty Cycle IC Power
Distance Power gain with (%) Density
(m) (dBm) cable loss (W/m^2)
(dBi)
1900 MHz PCS 29.10 1.70 100
2.4 GHz WLAN 16.45 1.70 100
Combined 0.20 2.52

The co-located Power Density is less than 10W/m^2 which is the limits for each separate
transmitter.

Conclusion
The TVG-850 EVDO is in compliance with FCC MPE limits for General Population /
Uncontrolled Exposure as a mobile device with a distance of greater than 20 cm from the
co-located antennas.
