EXHIBIT B Page 1 of 5 Analysis of Non—Ionizing Radiation for a 4.5 Meter Earth Station System This report analyzes the non—ionizing radiation levels for a 4.5 meter earth station system. The analysis and calculations performed in this report are in compliance with the methods described in the FCC Office of Engineering and Technology Bulletin, No. 65 first published in 1985 and revised in 1997 in Edition 97—01. The radiation safety limits used in the analysis are in conformance with the FCC R&O 96—326. Bulletin No. 65 and the FCC R&O specifies that there are two separate tiers of exposure limits that are dependant on the situation in which the exposure takes place and/or the status of the individuals who are subject to the exposure. The Maximum Permissible Exposure (MPE) limits for persons in a General Population/ Uncontrolled environment are shown in Table 1. The General Population/ Uncontrolled MPE is a function of transmit frequency and is for an exposure period of thirty minutes or less. The MPE limits for persons in an Occupational/Controlled environment are shown in Table 2. The Occupational MPE is a function of transmit frequency and is for an exposure period of six minutes or less. The purpose of the analysis described in this report is to determine the power flux density levels of the earth station in the far—field, near—field, transition region, between the subreflector or feed and main reflector surface, at the main reflector surface, and between the antenna edge and the ground and to compare these levels to the specified MPEs.

Far Field Distance Calculation The distance to the beginning of the far field can be determined from the following equation: (1) Distance to the Far Field Region, (Rf) = 0.60 * D**2 / lambda (1) 577.1 meters The maximum main beam power density in the Far Field can be determined from the following equation: (2) On—Axis Power Density in the Far Field, (Wf) Ges * P / 4 * II * Rf**2 (2) 0.107 Watts/meters*®*2 0.011 mWatts/com**2 2. Near Field Calculation Power flux density is considered to be at a maximum value throughout the entire length of the defined Near Field region. The region is contained within a cylindrical volume having the same diameter as the antenna. Past the boundary of the Near Field region the power density from the antenna decreases linearly with respect to increasing distance. The distance to the end of the Near Field can be determined from the following equation: (3) Extent of the Near Field, (Rn) D*+*2 / (4 * lambda) (3) 240.5 meters The maximum power density in the Near Field can be determined from the following equation: (4) Near Field Power Density, (Wn) 16.0 * n * P / II * D**2 (4) i1 0.264 Watts/meters*®*2 i 0.026 mWatts/cm**2

EXHIBIT B Page 3 of 5 3. Transition Region Calculations The Transition region is located between the Near and Far Field regions. The power density begins to decrease linearly with increasing distance in the Transition region. While the power density decreases inversely with distance in the Transition region, the power density decreases inversely with the square of the distance in the Far Field region. The maximum power density in the Transition region will not exceed that calculated for the Near Field region. The power density calculated in Section 1 is the highest power density the antenna can produce in any of the regions away from the antenna. The power density at a distance Rt can be determined from the following equation: (5) Transition region Power Density, (Tt) = Wn * Rn / Rt (5) 0.026 mWatts/cm**2 4. Region between Main Reflector and Subreflector Transmissions from the feed assembly are directed toward the subreflector surface, and are reflected back toward the main reflector. The most common feed assemblies are waveguide flanges, horns or subreflectors. The energy between the subreflector and the reflector surfaces can be calculated by determining the power density at the subreflector surface. This can be determined from the following equation: (6) Power Density at Feed Flange, (Ws) 4 * P / As (6) 2.614 mWatts/cm**2 5. Main Reflector Region The power density in the main reflector is determined in the same manner as the power density at the subreflector. The area is now the area of the main reflector aperture and can be determined from the following equation: (7) Power Density at the Main Reflector Surface, (Wm) = 4 * P / Sa (7) 0.480 Watts/meters*®*2 it 0.048 mWatts/cm**2 i 6. Reqion between Main Reflector and Ground Assuming uniform illumination of the reflector surface, the power density between the antenna and ground can be determined from the following equation: (8) Power Density between Reflector and Ground, (Wg) = P / Sa (8) 0.120 Watts/meters**2 0.012 mWatts/cm**2

EXHIBIT B Page 5 of 5 7. Conclusions Based on the above analysis it is concluded that harmful levels of radiation will not exist in regions normally occupied by the public or the earth station‘s operating personnel. The transmitter will be turned off during antenna maintenance so that the FCC MPE of 5.0 mW/oem**2 will be complied with for those regions with close proximity to the reflector that exceed acceptable levels.

Region between Feed Assembly and Antenna Reflector Transmissions from the feed assembly are Girected toward the antenna reflector surface, and are confined within a conical shape defined by the type of feed assembly. The most common feed assemblies are waveqguide flanges, horns or subreflectors. The energy between the feed assembly and reflector surface can be calculated by determining the power density at the feed assembly surface. This can be determined from the following equation: (6) Power Density at Feed Flange, (Wf) 4 * P / Fa (6) 168 .413 mWatts/cm**2 5.

The radiation safety limits used in the analysis are in conformance with the FCC R&O 96—326. Bulletin No. 65 and the FCC R&O specifies that there are two separate tiers of exposure limits that are dependant on the situation in which the exposure takes place and/or the status of the individuals who are subject to the exposure. The Maximum Permissible Exposure (MPE) limits for persons in a General Population/ Uncontrolled environment are shown in Table 1. The General Population/ Uncontrolled MPE is a function of transmit frequency and is for an exposure period of thirty minutes or less. The MPE limits for persons in an Occupational/Controlled environment are shown in Table 2. The Occupational MPE is a function of transmit frequency and is for an exposure period of six minutes or less. The purpose of the analysis described in this report is to determine the power flux density levels of the earth station in the far—field, near—field, transition region, between the subreflector or feed and main reflector surface, at the main reflector surface, and between the antenna edge and the ground and to compare these levels to the specified MPEs.

The power density calculated in Section 1 is the highest power density the antenna can produce in any of the regions away from the antenna. The power density at a distance Rt can be determined from the following equation: (5) Transition region Power Density, (Tt) Wn * Rn / Rt (5) 0 .450 mWatts/om**2 4. Region between Feed Assembly and Antenna Reflector Transmissions from the feed assembly are directed toward the antenna reflector surface, and are confined within a conical shape defined by the type of feed assembly. The most common feed assemblies are waveguide flanges, horns or subreflectors. The energy between the feed assembly and reflector surface can be calculated by determining the power density at the feed assembly surface. This can be determined from the following equation: (6) Power Density at Feed Flange, (Wf) 4 * P / Fa (6) 30.023 mWatts/cm**2 5. Main Reflector Region The power density in the main reflector is determined in the same manner as the power density at the feed assembly. The area is now the area of the reflector aperture and can be determined from the following equation: (7) Power Density at the Reflector Surface, (Ws) 4 * P / Sa (7) 6.755 Watts/meters**2 0.676 mWatts/cm**2 6. Region between Reflector and Ground Assuming uniform illumination of the reflector surface, the power density between the antenna and ground can be determined from the following equation: (8) Power Density between Reflector and Ground, (Wg) P / Sa (8) It 1.689 Watts/meters*®*2 it 0.169 mWatts/cm**2 it

EXHIBIT B Page 5 of 5 7. Conclusions Based on the above analysis it is concluded that harmful levels of radiation will not exist in regions normally occupied by the public or the earth station‘s operating personnel. The transmitter will be turned off during antenna maintenance so that the FCC MPE of 5.0 mW/cm**2 will be complied with for those regions with close proximity to the reflector that exceed acceptable levels.

Aloha Networks, Inc. FCC Form 442—Filing Document Exhibit C Demonstration of Compliance with FCC Rules Aloha Networks, Inc. seeks authority pursuant to Section 25.209(e) of the Commission‘s Rules, 47 C.F.R § 25.209(e), to operate a VSAT earth station antenna ranging from 0.45 to 1.2 meter in diameter. The antennas are the Channel Master 0.45m, 0.60m, 0.75m, 1.0m, and a 1.2 meter offset antenna system. As required by the rules attached are the following: (1) Exhibit D — Engineering analysis showing compliance with the two degree spacing policy for sub—meter VSAT antennas; (2) Exhibit E — Manufacturer antenna patterns for Mid Frequency Bands.

Aloha Networks, Inc. FCC Form 442—Filing Document This Exhibit will provide the technical analysis showing the performance of the Channel Master antennas (0.45, 0.60, 0.75, 1.0, and 1.2 meter) and space system transmission characteristics are compliant with the Commission‘s two degree (2 °) spacing policy. This Exhibit will show the adjacent satellite interference caused by transmissions from the Channel Master antenna (0.45 to 1.2—meter) will be no greater than an antenna compliant with the combined 47 C.F.R. § 25.209 and 25.212 for uplink EIRP density interference towards adjacent satellites spaced at two degree intervals of longitude in the azimuth axis and for proposed NGSO systems in the elevation axis. 2.0 Azimuth Axis System Performance Exhibit E (Antenna Patterns) provides the measured performance data for the Channel Master 0.45, 0.60, 0.75, 1.0, and 1.2 meter antenna referenced in this Exhibit. 2.1 Antenna Performance in the Azimuth Axis The measured data indicates that the 0.45, 0.60, 0.75, 1.0, and the 1.2 meter antenna are not compliant with the antenna pattern envelope specified in 47 C.EF.R. § 25.209(a) from 1° to 1.7° for the azimuth axis. However, the Channel Master antennas will meet the 29—25Log(O) specifications between 1.7° and 7° rather than 1.25° and 7° as specified in 47 C.F.R. § 25.209(g) for small antennas operating in the 12/14 GHz Band (Domestic FSS Ku—Band). Domestic FSS Ku—Band satellites are spaced at 2° intervals of longitude with respect to the center of the earth. However, the angular separation of the satellites as viewed by earth stations from the surface of the earth is nominally 2.3 °. Therefore, the antenna‘s compliance with the FCC requirements for angles 1.7° and greater will provide the required interference isolation performance toward adjacent satellites. Exhibit D — Page 2 of 8 September 4, 2001

Aloha Networks, Inc. FCC Form 442—Filing Document The Channel Master antennas referenced above are designed to use feeds to support either of the following configurations: 1) a single FSS (transmit/receive) satellite 2) a combination of FSS (transmit/receive) and BSS (receive only DBS) satellites in the mode where the antenna will only transmit and receive using a single FSS satellite, the satellites to be used for this operation are domestic satellites (assume to be full domestic arc). 2.2 Uplink Flange Density and Off—Axis EIRP Density Combining 47 C.F.R. § 25.209 (Antenna performance standards) and 25.212 (Narrow— Band Transmissions in the Fixed—Satellite Services) provides the maximum EIRP density a digital VSAT earth station can transmit toward an adjacent satellite. 47 C.F.R. § 25.209(a) determines the maximum acceptable VSAT earth station transmit antenna gain toward the adjacent satellite as follows: Maximum Transmit Antenna Gain at 2° = 29—25*Logi,(2°) dBi = 21.5 dBi 47 C.F.R. § 25.209© specifies a maximum acceptable digital VSAT earth station uplink power density at the antenna transmit flange of —14 dBW/4 kHz. Therefore, the maximum adjacent satellite interference (ASI) EIRP density can be determined by combining 47 C.F.R. § 25.209(a) and 25.212(c) in the following formula: Maximum ASI EIRP Density = Max. Transmit Antenna Gain at 2° + Max. Transmit Power Density at Antenna Flange = 21.5 dBi + (—14 dBW/4 kHz) =7.5 dBW/4 kHz The following table provides the uplink flange density and EIRP density toward the two— degree adjacent satellites for all Aloha Networks proposed remote antenna system transmit data rates, modulation, transmit power, and bandwidth. A transmission line loss Exhibit D — Page 3 of 8 September 4, 2001

Aloha Networks, Inc. FCC Form 442—Filing Document of 0.2 dB between the HPC (transmit HPA) and the antenna flange and the gains of each remote antenna at 2° boresight are used in calculating the uplink flange density and EIRP density. 2.3 Conclusion Section 2 of this Exhibit showed that each of the remote antenna (0.45, 0.60, 0.75, 1.0, and 1.2 meter) are compliant with the 47 C.F.R. § 25.209 antenna pattern envelope in the direction of the adjacent satellites spaced at two degrees from the space satellite. The table in this Exhibit indicates in all transmission cases the uplink flange density is below the maximum specification of —14 dBW/4 kHz (47 C.F.R. § 25.212{c}). Also, the EIRP density in the direction of the adjacent satellites at two degrees of separation will be below the +7.5 dBW/ 4 kHz maximum EIRP density criteria for adjacent satellite interference required by the combination of 47 C.F.R. § 25.209 and 25.212. Therefore, for the critical adjacent satellite interference specification of EIRP density at two degrees from boresight, the remote antennas to be use by Aloha Networks, Inc. will provide performance equivalent to an antenna that is compliant with applicable 47 C.F.R. § 25 rules.

Aloha Networks, Inc. FCC Form 442—Filing Document 3.0 Elevation Axis System Performance The reflectors of the remote antennas are elliptically shaped. The antenna performance in the elevation axis is not a concern for the current Ku—Band geostationary (GEO) satellites but is a potential concern for proposed non—geostationary (NGSO) satellite systems which desire to use the same frequency band as the domestic US FSS Ku—Band used by Aloha Networks‘ VSAT networks. This section will address the interference into NGSO systems from the referenced Channel Master Remote Antenna elevation axis. 3.1 Antenna Performance in the Elevation Axis As seen in Exhibit E (Antenna Patterns), the remote antennas transmit performance in the elevation axis are compliant with the 47 C.F.R. § 25.209 antenna pattern specification 32— 25*Logi,(O) dBi starting at 2.5 degrees off boresight. Also from Exhibit E, at two degrees from boresight the gains of the 0.45 and 0.60—meter antennas are 31.7 and 27.2 dBi while 47 C.F.R. § 25.209 provides for an antenna gain of 24.5 dBi at two degrees, a difference of 7.2 dB for the 0.45m remote antenna and 2.7 dB for the 0.60m remote antenna. Table 2: Antenna Gains @ 2° off Boresight (dB) Exhibit D — Page 6 of 8 September 4, 2001

Aloha Networks, Inc. FCC Form 442—Filing Document 3.2 Uplink Flange Density and Off—Axis EIRP Density The table (table 1) in this Exhibit indicates the maximum uplink flange density to be used for carrier transmission from the remote antennas is —25 dBW/4 kHz rather than the maximum allowable —14 dBW/4 kHz under 47 C.F.R. § 25.212 for narrow and/or wideband digital services. Therefore, the EIRP density at two degrees off boresight in the elevation axis will be the combination of the antenna performance and the maximum uplink flange density which equates to the following: EIRP Densi 2 off Boresight in the elevation axis a) 0.45 m: 31.7 dBi + (— 25 dBW/4 kHz) = 6.7 dBW/4 kHz b) 0.60 m: 27.2 dBi + (— 25 dBW/4 kHz) =2.2 dBW/4 kHz c) 0.75 m: 24.1 dBi + (— 25 dBW/4 kHz) =— 0.9 dBW/4 kHz d) 1.0 m: 13.3 dBi + (— 25 dBW/4 kHz) =— 11.7 dBW/4 kHz f) 1.2 m: 12.3 dBi + (— 25 dBW/4 kHz) =— 12.7 dBW/4 kHz Also specified in 47 C.F.R. § 25.212 is the uplink flange density limit for narrow—band analog carriers. For these carriers the uplink flange density limit is —8 dBW/4 kHz. This is 6 dB higher than the digital service limit. Since the FSS Ku—Band is used by both analog and digital services the NGSO systems will need to be designed for the worst case analog FSS densities. Combining 47 C.F.R. § 25.209 and 25.212 for analog services the maximum off—axis EIRP density at two degrees in the elevation axis is: Max. Elevation Axis EIRP Density at 2° = 32—25Log(2")+(—8 dBW/4 kHz) = 16.5 dBW/4 kHz Therefore, the narrow—band analog off—axis EIRP density at 2° is 16.5 dBW/4 kHz which is 9.8 dB higher than the 6.7 dBW/4 kHz maximum EIRP density. 3.3 ITU Recommendation Exhibit D — Page 7 of 8 September 4, 2001

Aloha Networks, Inc. FCC Form 442—Filing Document The ITU is working to provide recommended off—axis power density specifications for the operation of proposed NGSO systems using the same frequency band as the Region 2 FSS Ku—Band (11.7 to 12.2 GHz space to earth and 14.0 to 14.5 GHz earth to space) as Aloha Networks VSAT networks plans to utilize. Chapter 3 of the latest ITU CPM Report, prepared by the ITU for the WRC—2000, indicates that the off—axis EIRP density levels allowed are much less stringent than the combined levels from 47 C.E.R. § 25.209 and 25.212 (by over 10 dB). ITU—R document $.524 also discusses this issue as well. In the ITU documents, there are different levels specified for different carrier types, the FM— TV levels being over 11 dB more permissible. 3.4 Existing HNS EKlliptical Antennas Hughes Networks Systems (HNS) has an existing FCC license (call sign E900682) which includes an antenna with a dimension of 46 cm in the elevation axis compared to the higher dimensions for the Aloha Networks remote antennas. Therefore, there is already a licensed antenna with similar, and most likely worse, antenna pattern performance in the elevation axis. The HNS application indicates the maximum uplink flange density, which will be used with this antenna, is the maximum allowable in 47 C.F.R. § 25.212 of —14 dBW/4 kHz. HNS has deployed elliptical shaped VSAT antennas at many of its customer‘s sites including thousands of US based installations at Mobile gas stations. 3.5 Conclusion For future NGSO system interference concerns, the Aloha Networks remote antenna applications will have off—axis EIRP density performance below currently operational FSS systems, FSS maximum limits and the ITU recommendations.

Aloha Networks, Inc. FCC Form 442—Filing Document Exhibit G Testing Program Description Aloha Networks, Inc. is a VSAT network supplier which has developed advanced commercial VSAT services using the ALOHA access protocol. Aloha Networks has developed Spread ALOHA ® Multiple Access (SAMA*"), a spread—spectrum multiple access technology that overcomes the current bottleneck in two—way digital wireless communication networks by providing an improved access methodology required for very large numbers of remote users. Aloha would like to perform some system testing in order to determine the operational viability of their new spread—spectrum based transmission scheme using sub—meter remote facilities. Aloha proposes to employ a 4.5 meter hub earth station and VSAT terminals employing antennas ranging in size from 45 cm to 1.2 meters as remotes. Initially the hub and remotes will be collocated at their facilities in San Francisco, CA. Eventually up to 50— 250 antennas will be located at positions in the continental United States (CONUS) to examine the impact of multiple remote users distributed across the country. Aloha believes there VSAT network access architecture and RF design will allow for sub—meter remote terminals however they would like to ensure proper system performance prior to launch of a commercial version on this product. Using a moderately large number of distributed remote terminals over a several month period will allow Aloha Networks to accurately analyze the product‘s performance and identify the feasibility of certain remote configurations and assist in the optimization of the design.
