All rights reserved. The Low Power Base Station must be professionally installed to ensure that all regulatory requirements are met. These include but are not limited to: local building and safety codes, National Electrical Code, and the FCC rules and regulations. The NextNet Wireless Low Power Base Station is a fixed product that operates as a point-to-point wireless data link. As such, this product is only authorized to operate as manufactured by NextNet Wireless and cannot be modified to operate in any other manner. Installers must ensure that this product complies with the FCC rules. Modifications to this product would be in violation of the FCC rules detailed in 47CFR15.247(b)(3)(iii) which states: Fixed, point-to-point operation, as used in paragraphs (b)(3)(i) and (b)(3)(ii) of this section, excludes the use of point-to-multipoint systems, omnidirectional applications, and multiple co-located intentional radiators transmitting the same information. The operator of the spread spectrum intentional radiator or, if the equipment is professionally installed, the installer is responsible for ensuring that the system is used exclusively for fixed, point-to-point operations. WARNING: This equipment has been tested and found to comply with the FCC guidelines as found in 47CFR1.1310 for Radio Frequency Radiation Exposure Limits as detailed below. A minimum of 36 centimeters or 14 inches of separation between the base station antenna and all persons must be maintained. Radio Frequency Radiation Exposure Limits (FCC Rules 47CFR1.1310) f = frequency in MHz * = Plane-wave equivalent power density NOTE 1 TO TABLE 1: Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. Limits for occupational/controlled exposure also apply in situations when an individual is transient through a location where occupational/controlled limits apply provided he or she is made aware of the potential for exposure. NOTE 2 TO TABLE 1: General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential or commercial installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a TABLE 1.

The Base Station is capable of transmitting at a 100 % duty cycle while in test mode. The NextNet Wireless BTS- 2400-AV Base Station contains an integral antenna vertically polarized and is sealed inside the unit. The maximum vertical polarization antenna gain is 15 dBi. Therefore the maximum radiated transmit power would be: 100 % Transmit duty cycle: Pmax = Ptx + G(antenna) Pmax = 27 (dBm) + 15 (dBi) = 27 + 15 Pmax = 42 dBim = 15.85 Watts EIRP The following calculations can be used to determine the distance from the transmitting antenna that must be maintained to ensure that the exposure limit as defined in Table 1 of part 1.1310 (B) Limits for General Population/Uncontrolled Exposure and part 1.1310 (A) Limits for Occupational/Controlled Exposures. The formula for the following calculations are found in the OET Bulletin 65, edition 97-01 August 1997, “Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields”. It is noted that the formulas from Bulletin 65 are for prediction of power density in the far-field of the antenna and will over predict the requirements in the near-field.

S = EIRP/4 πR 2 or R = (EIRP/4πS) 0.5 EIRP = 15.85 W EIRP = 15,850 mW EIRP For S = 1 mW/cm 2 R = (15850/(4*π*1)) 0.5 R = 35.51 cm For S = 5 mW/cm 2 R = (15850/4*π*5) 0.5 R = 15.88 cm The calculated safe distance from a transmitting antenna considered to be a point source radiation element is 35.51 cm for the general population and is 15.88 cm for occupational exposure. The antenna to be used for this base station is a phased array patch antenna that is integral to the product and is not detachable. A measurement of the power density at 36 cm and the distance from the antenna to achieve 1 mW/cm 2 of power density is detailed below.

Expedience system operates as a Time Division Duplex (TDD) product with a Time Division Multiplex (TDM) frame structure. Because the base station is capable of transmitting at a 100% duty cycle in test mode, radiation hazard testing is performed with the maximum exposure potential. To measure the RF Exposure, the base station transmitter is enabled in a test mode and transmitting random data at the 0.5 watt power level into the integral antenna. Measurements are performed at the low, mid, and high channels and 4-QAM, 16-QAM, and 64-QAM modulation formats. Measurement distances are from the surface of the antenna pc board and are not from the surface of the radome cover. Test Conditions: Freq…

NextNet Wireless, Inc 09/27/2004 FCC Rule Part Description Response 15.31(m) Number of measurement frequencies 3 (low, middle, high) 15.215(c) § 15.215 Additional provisions to the general radiated emission limitations. (c) Intentional radiators operating under the alternative provisions to the general emission limits, as contained in §§15.217 through 15.257 and in subpart E of this part, must be designed to ensure that the 20 dB bandwidth of the emission is contained within the frequency band designated in the rule section under which the equipment is operated. The requirement to contain the 20 dB bandwidth of the emission within the specified frequency band includes the effects from frequency sweeping, frequency hopping and other modulation techniques that may be employed as well as the frequency stability of the transmitter over expected variations in temperature and supply voltage. If a frequency stability is not specified in the regulations, it is recommended that the fundamental emission be kept within at least the central 80% of the permitted band in order to minimize the possibility of out-of-band operation. Pass See pages 47-52 15.247 Operation within the bands 902–928 MHz, 2400–2483.5 MHz, and 5725–5850 MHz. 15.247(a)(2) Systems using digital modulation techniques may operate in the 902–928 MHz, 2400– 2483.5 MHz, and 5725–5850 MHz bands. The minimum 6 dB bandwidth shall be at least 500 kHz. Pass See pages 5-11 15.247(b)(3) The maximum peak output power of the intentional radiator shall not exceed the following: For systems using digital modulation in the 902–928 MHz, 2400– 2483.5 MHz, and 5725–5850 MHz bands: 1 Watt. Pass See pages 12-18 15.247(b)(4)(i) Except as shown in paragraphs (b)(3) (i), (ii) and (iii) of this section, if transmitting antennas of directional gain greater than 6 dBi are used the peak output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1) or (b)(2) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. Systems operating in the 2400–2483.5 MHz band that are used exclusively for fixed, point-to-point operations may employ transmitting antennas Pass See page 12 Also see “Exhibit 8 Installation Manual”. 9555 James Ave. South Suite 270 Bloomington, MN 55431 Exhibit 6 FCC ID: PHX-BTS2400A Test Report Page 3 of 103 with directional gain greater than 6 dBi provided the maximum peak output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6 dBi. 15.247(b)(4)(iii) F…
