RF Exposure / RF Technical Brief BABT TCB Balfour House, Churchfield Road, Walton-on-Thames, Surrey, KT12 2TD ATTN: Reviewing Engineer RF exposure information for the equipment VIP4G (FCC ID: NS9VIP4GABGN20, IC: 3143A- VIP4GABGN20) 1. Introduction: The device VIP4G (FCC ID: NS9VIP4GABGN20, IC: 3143A-VIP4GABGN20) is designed to be used only for fixed and mobile applications. This product integrates a Novatel Wireless' Expedite® E371 PCI Express Mini Card (FCC ID: PKRNVWE371, IC: 3229A-E371). The Novatel Wireless' Expedite® E371 PCI Express Mini Card is granted with a modular approval for mobile applications and the highest antenna gains allowed for use with this module for mobile RF exposure conditions are 3.5 dBi (850 MHz), 5.0 dBi (700 MHz), 5.0 dBi (1700 MHz), and 3.0 dBi (1900 MHz). The antenna(s) used for VIP4G transmitter and the antenna used for Novatel Wireless' Expedite® E371 PCI Express Mini Card are co-located and can transmit simultaneously. All the antennas must be installed to provide a separation distance of at least 20 cm from all the persons. 2. MPE limits: The table below is excerpted from RSS-102, Issue 4, 4.2, titled “RF Limits for Devices used by the General Public”: Frequency Range Power density Power density Averaging time (MHz) (W/m2) (mW/cm2) (minutes) 300 – 1500 f (MHz)/150 f (MHz) /1500 6 1500 – 15000 10 1.0 6 The table below is excerpted from Table 1B of 47 CFR 1.1310 titled Limits for Maximum Permissible Exposure (MPE), Limits for General Population/Uncontrolled Exposure: Frequency Range (MHz) Power density (mW/cm2) Averaging time (minutes) 300 – 1500 f (MHz) /1500 30 1500 – 100.000 1.0 30 3. Compliance criteria: Power density of individual transmitters is calculated using the equation: PG S 4 R 2 where: S = power density (in appropriate units, e.g. mW/cm2) P = power input to the antenna (in appropriate units, e.g., mW) G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) 3.1. Standalone compliance criteria: Power density must be lower than the MPE limits stated in item 2.

3.2. Simultaneous transmission compliance criteria The sum of the MPE ratios (Power density/MPE limit) for all simultaneous transmitting antennas incorporated in the device based on the calculated power density is ≤ 1.0. 4. Compliance calculations: 4.1.
