I was on the search to figure out how to turn off the WIFI Radio on the ZTE MF279 and I came across the RF Exposure Evaluation Report that was sent to the FCC. It was kind of hard to find so I thought If you had any interest in these frequencies, and wavelengths, and mW Ratings of these frequencies you’re at the right place.
The Original Article is located here: https://fccid.io/SRQ-MF279/RF-Exposure-Info/RF-Exposure-3568615
The RF Exposure Evaluation Report was Report # FA762107, Rev. 01, Issued on September 15, 2017.
I’m going to highlight some of the charts and data that I found interesting:

RF Exposure Limit Introduction According to ANSI/IEEE C95.1-1992, the criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio frequency (RF) radiation as specified in §1.1310. The MPE was calculated at 20 cm to show compliance with the power density limit. The following formula was used to calculate the Power Density: Where: S = Power Density P = Output Power at Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna Sporton International (KunShan) INC.

Collocated Power Density Calculation WWAN 2.4GHz WLAN 5GHz WLAN Σ(Power Density / Limit) of WWAN+2.4GHz WLAN+5GHz WLAN 0.091 0.020 0.022 0.133 Power Density / Limit Note: 1. For colocation analysis, WCDMA Band V is chosen for summation due to the highest (power density/limit) among all WWAN wireless modes. 2. Σ(Power Density / Limit): This is a summation of [(power density for each transmitter/antenna included in the simultaneous transmission)/ (corresponding MPE limit)]. Conclusion: According to 47 CFR §2.1091, the RF exposure analysis concludes that the RF Exposure is FCC compliant. Sporton International (KunShan) INC.
