FCC Part 2 also provides requirements for some transmitters with specific usage. This exhibit provides information relating to the specific requirements for the Motorola CPE transceiver for compliance with the RF Exposure requirements of FCC Parts 1, 2 and 101, and FCC Office of Engineering and Technology (OET) Bulletin 65. 13.1Environmental Assessment FCC Part 1, Paragraph 1.1307 and OET Bulletin 65, Appendix A, Table 1, state that “Routine Environmental Evaluation” must be performed for LMDS transmitters if: a) for non-building-mounted antennas, the height above ground level to the lowest point of the antenna is less than 10 meters AND the power is greater than 1640 Watts EIRP b) for building-mounted antennas, the power is greater than 1640 Watts EIRP. The Motorola CPE transmitter at maximum rated operating power has an EIRP of 316 Watts, considerably less than that required for an Environment Assessment. However, an Environmental Assesment was performed on the Motorola CPE. Figure 13-1 is a copy of that assesment. As can be seen from this assesment the RF exposure levels do not exceed the 1mW /cm 2 level for uncontrolled environments. 13.2Radio Frequency Radiation Exposure Evaluation Assessment FCC Part 2, Paragraph 2.1091 defines the requirements for a radio frequency radiation exposure evaluation for mobile devices and 2.1093 defines the same for portable devices. The Motorola CPE is neither mobile nor portable and is therefore considered exempt from these requirements. Exhibit 13 Page 2 of 7FCC ID: MIJTELCPE-USB-01 3/1700 13.3Effective Isotropic Radiated Power (EIRP) and Power Density Calculations The maximum EIRP from the Motorola CPE transmitter is 316 Watts (+25 dBW), based on a maximum power output of 0.100 Watts (-10dBW) and a typical antenna gain of 35 dBi. The maximum on-axis power density of High Gain transmitter was measured at 0.46 mW/cm 2 . 13.4Labeling Requirements Part 1, Paragraph 1.1307, Table 1 specifies that LMDS subscriber transceivers are required to have a label which provides adequate notice regarding potential radio frequency hazards relative to the limits of Part 1, Paragraph 1.1310.

Exhibit 12 Page 1 of 3FCC ID: MIJTELCPE-USB-01 11/24/99 Exhibit 12 – Measurement Techniques Motorola Customer Premise Equipment (CPE) FCC ID: MIJTELCPE-USB-01 Telaxis Model No. XCV-31-UB1H-R2 12.0 Measurement Techniques 12.1 Radiated Spurious and Harmonic Emissions 12.1.1 Definition Radiated spurious and harmonic emissions from the equipment at a frequency and/or frequencies which are outside an occupied band sufficient to insure transmission of information of required quality for the class of communication desired. The reduction in the level of these spurious emissions will not effect the quality of information being transmitted. 12.1.2 Minimum Standard For the CPE data transmitter, the mean power of radiated spurious and harmonic emissions shall be attenuated as per 101.12(a)(2)(ii). The frequency offset attenuation is based on an authorized bandwidth of 75 MHz and mean output power of +24 dBm. For frequencies removed greater than 50% to less than or equal to 250% of the authorized bandwidth and measured in a 1 MHz bandwidth, the attenuation requirement is as follows: Attenuation (dBc) = 12 + 0.4 * (Percent-50)+10 * Log 10 (Bandwidth) Note: Attenuation of greater than 56 dBc is not required. For frequencies removed greater than 250% of the authorized bandwidth and measured in a 4 kHz bandwidth, the attenuation requirement is as follows: Attenuation (dBc) = 43 + 10 * Log 10 (mean output power) Note: Attenuation of greater than 80 dBc is not required. Exhibit 12 Page 2 of 3FCC ID: MIJTELCPE-USB-01 11/24/99 12.1.3 Method of Measurement Facility Description: All final testing reported herein was performed at the Motorola SSG semi-anecohic chamber, located at 8201 E. McDowell Rd., Scottsdale, AZ. 85252. The facility has also been issued a Certificate of Accreditation through the National Voluntary Laboratory Accreditation Program (NVLAP) by NIST. This is under NVLAP Code: 100405-0 and is effective through September 30, 2000. Measurement Description: Spurious and harmonic emissions were measured as radiated emissions in an anecohic chamber (6.1m x 7.3m x 4.9m). The HUB equipment does not require a CPE to operate. The CPE requires the HUB’s Pilot tone to enable it to transmit. Therefore, when the HUB was tested only the HUB was in the test chamber and when the CPE was tested with both the HUB and the CPE in the chamber. The DOCSIS modulation was provided by a Rohde and Schwartz Signal Generator SMIQ. Radiated emissions were measured from 30 MHz to 100 GHz. For all emissions with the exception of the transmitter’s fundamental frequency and its harmonics, measurements were made at a distance of 3 meters. All four sides of the EUT and both vertical and horizontal polarizations were tested for maximum radiated levels. All emissions detected were greater than 20 dB below the emission limitations of 47 CFR 101.111 (see paragraph 12.1.2 of this Exhibit). Therefore, no Open Area Test Site (OATS) measurements were made. Testing of the transmitter’s fundamental frequency and its harmonics were performed in the main beam of the transmit antenna. The receive antenna was positioned at a distance to maximize the received signal. Spurious and harmonic levels were then compared to the radiated level of the fundamental signal. The attenuation requirement was based on 47 CFR 101.111 (see paragraph 12.1.2 of this Exhibit). 12.2 Frequency Stability 12.2.1 Definition The carrier frequency stability is the ability of the transmitter to maintain an assigned carrier frequency 12.2.2 Minimum Standard The minimum frequency stability shall be 0.001% at any time during normal operation. Exhibit 12 Page 3 of 3FCC ID: MIJTELCPE-USB-01 11/24/99 12.2.3 Method of Measurement The CPE was placed in a temperature chamber. The support equipment (signal generator, spectrum analyzer and voltage power supply) were placed external to the chamber. The temperature was varied from –30 o to 50 o C in 10 o steps. The CPE was allowed to aclimate at each temperature setting. At each temperature increment, a frequency measurement was made at the ± 15% limits of the input supply voltage.

Subsequent to the origial filing a second modulation scheme has been implemented. I am also providing this new data for your review. Modulation/ Symbol Rate (MS/ Sec.)

A software modification is required for the CPE to cover each of the 25 MHz sub-bands that make up the 31.225 – 31.300 GHz allocated band. The lower and upper edge guardbands are required to meet the emission mask requirements. The new emission designators are: • 16 QAM 0.384 MS/s– 561KD1D • QPSK 2.56 MS/s – 3M46G1D The following is a list of the data provided: 1. 16 QAM data carrier at 31.2256 GHz compared to digital emission mask (101.111(a)(2)) – closeup of band edge 2.

While I agree with your figures of - 29.75 and –56 dBc, I was under the assumption that the 86.25 and 187.5 MHz frequencies were relative to the allocated band center frequency and independent of carrier frequency.
