RF Safety Requirements to 2.1091 for Mobile Transmitters According to Section 3 of Supplement C to OET Bulletin 65, Part 15 Transmitters are categorically excluded from Routine Environmental Evaluation by measurement or precise computations unless otherwise required by the Commissions The unit under evaluation has 2 internal antennas of 0 dBi gain (for Diversity) with a measured output power output of 0.235 Watts at the antenna terminals. Additionally, page 7 of the users manual specifies to install the device at least 20 cm away from the users or other individuals. Due to the low power of the EUT, environmental evaluation should be deemed unnecessary since the EUT’s operational frequency range is 2.4-2.4835 GHz and the ERP is considerably less than 3 Watts.

Processing Gain for the HWN TransPort The radio transmitter and receiver in the Home Wireless Networks TransPort Wireless LAN Access Point is capable of operation at over-the-air data rates of 1 MBPS, 2 MBPS, 5.5 MBPS, and 11 MBPS. The following table illustrates the differences in modulation, data, and symbol rates for each mode: Data Ra tes and Mod ulation HWN Tra nsPort Data Rate (MBPS) Mod ulationSymbol Rate (MSPS) Chip Rate (MCPS) Spreading Gain (dB) Coding Gain (dB) Theoretical Processing Gain (dB) Theoretical Es/No at 10e-5 BER (dB) Mini mum J/S ratio for 10 dB processing gain (dB) (with 2 dB allowable system loss) 1BPSK11110.4010.411 - 3 2QPSK11110.4010.411-3 5.5CCK1.37589.02.211.216.2-8.2 11CCK1.37589.02.211.216.4-8.4 The performance of the HWN TransPort has been tested in accordance with the CW jamming margin test of FCC rules Part 15.247(e). Below is a summary of the theoretical basis behind the performance of the equipment at the 5.5 and 11 MBPS modes with 8 chips/symbol. Performance of the 1 and 2 MBPS modes is based upon the calculations given in 15.247(e) at 11 chips per symbol and does not require additional theoretical basis. Theoretical calculations for 5.5 and 11 MBPS Modes The processing gain is re lated to the jamming margin as follows [2]: system output p L S J N S G +       +       = Where BER REFERENCE is the reference bit error ratio with its corresponding, theoretical output signal to noise ratio per symbol, (S/N) output , (J/ S) is the jamming margin (jamming signal power relative to desired signal power), and L system are the system implementation losses. The maximum allowed total system imple mentation loss is 2 dB. The HFA3860B direct sequence spread spectrum baseband processor uses CCK modulation for 5.5 and 11 MBPS modes, which is a form of M-ary Orthogonal Keying. The BER performance curve is given as: “ The probability of error for generalized M-ary Orthogona l signaling using coherent demodulation is given by: PPQz Ez dz ec b M S N =− =−−+               −       − − ∞ ∫ 11 1 2 212 2 1 2 1 2 01 0 π η ()exp This integral cannot be solved in closed form, and numerical integration must be used. There are error rate extensions for differential decoding and descrambling that are also to be accounted for. This is done in a MATHCAD environment and is displayed in graphical format below. 1.11000 byte PER vs. Es/No 15.51616.517 10 -2 10 -1 10 0 11 Mbps CCK in Thermal Noise Es/No (dB) 1000 byte Packet Error Rate The reference PER is specified as 8% . The corresponding Es/No (signal to noise ratio per symbol) is 16.4 dB. The Es/No required to achieve the desired BER with maximum system implementation losses is 18.4 dB. The minimum processing gain is again, 10 dB, therefore: dB S J dBdBL S J N E G system output o s p 100.24.16 ≥       ++=+       +         = dB S J dBG p 104.18 ≥       += The minimum ja mmer to signal ratio is as follows: dB S J 4.8 −≥       For the case of the HFA3860B, the bit rates are 1, 2, 5.5, and 11 Mbps. The corresponding symbol rates are 1, 1, 1.375, and 1.375 MSps. The chip rate is always 11 MCps, so the ratio of chip rate to symbol rate is 11:1 for the 1 and 2 Mbps rates and 8:1 for the 5.5 and 11 Mbps rates. Since the symbol rate to bit rate is less than 10 for the higher rates, we supply the theoretical processing gain calculation for these cases where spread spectrum processing gain with embedded coding gain is utilized. This is reasonable in that they cannot be separated in the demodulation process. If a separable FEC coding scheme were used, we would not be comfortable making this assertion. As can be seen from the curve of figure 1, the Es/N0 is 16.4 dB at the PER of 8%. This PER can be related to a BER of 1e-5 on 1000 byte packets. With 8 bits per symbol, the Eb/N0 is then 7.4 dB or 9 dB less than the Es/N0. It is well known that the Eb/N0 of BPSK is 9.6 dB for 1e-5 BER, so therefore the coding gain of CCK over BPSK is 2.2 dB. We add this to the processing gain of 9 dB to get 11.2 dB overall processing gain for the CW jammer test. Taking the calculations above, if the J/S >= -8.4 dB then the equipment passes the CW jamming test in 11 MBPS modes. For 5.5 MBPS modes, the HFA3860B data sheet shows that the required Es/No is 0.2 dB less than that required for the 11 MBPS mode. Thus if the J/S >= -8.2 dB then the equipment passes the CW jamming test in 5.5 MBPS modes.

The Model 95-0016-XXX is an IEEE 802.11 Wireless Ethernet Transceiver Module (2.4 GHz) with diversity which may be used as either a self contained unit or attached to Home Wireless Networks, Inc. NCU controller (model 95-0005-XXX) for added functionality and communication with other Home Wireless Networks, Inc. products. When utilized as a self contained unit, the EUT obtains power through use of an external AC adapter. Units used with a NCU controller are connected directly to the bottom side of the NCU and obtain their power from the NCU through the interface connecting the two units. The following is a list of the channels designed into the EUT: RF Frequencies HWN IEEE 802.11 Wireless Ethernet Module RF CHANNEL TRANSMIT/RECEIVE FREQUENCY (MHZ) RF LOCAL OSCILLATOR FREQUENCY (Internal radio version only) 124122038 224172043 324222048 424272053 524322058 624372063 724422068 824472073 924522078 1024572083 1124622088 FCC ID: NSK0016B 1.2Related Submittal(s)/Grant(s) The EUT will be used with part of a system to send/receive data. The transceiver presented in this report will be used with other like transceivers. The EUT may also be used along with a Home Wireless Networks, Inc. Model 95-0005-XXX which has been previously submitted and approved under FCC ID: NSK0005A. The EUT is subject to the following authorizations: a) Certification as a transmitter b) Certification or DoC as a computer peripheral device c) Verification as a receiver and digital device The information contained in this report is presented for the certification portion of the EUT. A separate report (UST # 00-0173) has been issued which covers the requirements for the DoC & verification authorization(s) for the EUT. FCC ID: NSK0005A SECTION 2 TESTS AND MEASUREMENTS FCC ID: NSK0005A TEST AND MEASUREMENTS 2.1 Configuration of Tested System The sample was tested per ANSI C63.4, Methods of Measurement from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (1992). Conducted and radiated emissions data were taken with the test receiver or spectrum analyzer's resolution bandwidth adjusted to 9 kHz and 120 kHz, respectively. All measurements are peak unless stated otherwise. The video filter associated with the spectrum analyzer was off throughout the evaluation process. Interconnecting cables were manipulated as necessary to maximize emissions. Interconnecting cables were manipulated as necessary to maximize emissions. A block diagram of the tested system is shown in Figure 1. Test configuration photographs for spurious and fundamental emissions are shown in Figure 2. The EUT is internally identical for both versions (self contained versus for use with NCU). The unit that connects to a NCU controller was selected for testing since it consists of additional electrical devices connected to the EUT. Since AC power is supplied either directly to the unit in a self contained configuration, or through the NCU when used in it is connected to the EUT, two separate conducted emissions tests were performed. The sample used for testing was received by U.S. Technologies on April 19, 2000 in good condition. 2.2 Test Facility Testing was performed at US Tech's measurement facility at 3505 Francis Circle, Alpharetta, GA. This site has been fully described and submitted to the FCC, and accepted in their letter marked 31040/SIT. Additionally this site has also been fully described and submitted to Industry Canada (IC), and has been approved under file number IC2982. 2.3 Test Equipment Table 2 describes test equipment used to evaluate this product. 2.4 Modifications No modifications were made by US Tech, to bring the EUT into compliance with FCC Part 15 limits for the transmitter portion of the EUT.

FCC ID: NSK0016B 2.8 Antenna Conducted Spurious Emission in the Frequency Range 30 - 25000 MHz (FCC Section 15.247(c)) Antenna conducted spurious emissions in the frequency range 30-25000 MHz have been measured with a spectrum analyzer by connecting the spectrum analyzer directly via a short cable to the antenna output terminals or across the antenna leads on the PCB as specified by the manufacturer. The spectrum analyzer was set for a 50 Ω impedance with the RBW = 100 kHz & VBW > RBW. All spurious emissions were measured to be greater than 20 dB down from the fundamental. The results of conducted spurious emissions are given in Figure 4a through Figure 4x.

FCC ID: NSK0016B 2.9 Peak Radiated Spurious Emission in the Frequency Range 30 - 25000 MHz (FCC Section 15.247(c)) A preliminary scan was performed on the EUT to determine frequencies that were caused by the transmitter portion of the product. Significant emissions that fell within restricted bands were then measured on an OAT’s site. Radiated measurements below 1 GHz were tested with a RBW = 120 kHz. Radiated measurements above 1 GHz were measured using a RBW = VBW = 1 MHz. The results of peak radiated spurious emissions falling within restricted bands are given in Table 4a & 4d (low), Table 4b & 4e, (mid), Table 4c & 4f (high) and Figure 5a – 5f.
