USER’S MANUAL INFORMATION (PRELIMINARY) The User’s Manual is in preparation. The following material will be contained in the manual: FCC ID: MYF-WL-2401 IC: 2837A -WL-2401 This device complies with Part 15 of the FCC Rules and with RSS- 210 of I ndustry Canada. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. WARNING: Changes or modifications not expressively approved by the party responsible for compliance could void the user's authority to operate the equipment. The term “IC:” before the radio certification number only signifies that Industry Canada technical specifications were met. NOTE: The antenna system shall be installed ONLY by experienced antenna installers who are familiar with local building and safety codes, and wherever necessary have been licensed by appropriate government regulatory bodies. Failure to do so may void the Product Warranty, as well as expose the end-user to legal and/or financial liabilities. Hyperlink Technologies, its agents, resellers or distributors, are not liable for injury, damage, or violation of government regulations that may arise from failing to comply with the guidelines described in this document. Caution: Exposure to Radio Frequency Radiation. The radiated output power of this product is below the FCC radio exposure limits. Nevertheless, this product shall be used in such a manner that the potential for human contact during normal operation is minimized. Antenna shall be mounted in such a manner as to minimize the potential for human contact during normal operation. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not be less than 20 cm (8 inches) during normal operation. Hyperlink Technologies is not responsible for any radio or television interference caused by unauthorized modification of this device or the substitution or attachment of connecting cables and equipment other than specified by Hyperlink Technologies. The correction of interference caused by such unauthorized modification, substitution or attachment will be the responsibility of the user. The following table summarizes the minimum separation distance as calculated following FCC OET Bulletin 65. Because of the large variation in antenna and amplifier configurations, minimum separation distance is calculated over the full range of total EIRP only. To obtain the minimum separation distance for a particular system, the antenna gain (dBm) listed in Table 1.2 must be added to the amplifier output power (dBm) listed in Table 1.3, resulting in the total EIRP for a given system. If no amplifier is used, the output power of the radio from Table 1.2 is to be used in place of the amplifier output power. Cross referencing this EIRP (dBm) with that listed below will give the corresponding minimum separation distance for the given system. NOTE: THE ONLY PERMISSIBLE SYSTEM CONFIGURATIONS ARE THOSE LISTED IN THE SYSTEM CONFIGURATION TABLE AT THE END OF THIS MANUAL.

RF EXPOSURE The following table summarizes the minimum separation distance as calculated following FCC OET Bulletin 65. Because of the large variation in antenna and amplifier configurations, minimum separation distance is calculated over the full range of total EIRP only. To obtain the minimum separation distance for a particular system, the antenna gain (dBm) listed in Table 1.2 must be added to the amplifier output power (dBm) listed in Table 1.3, resulting in the total EIRP for a given system. If no amplifier is used, the output power of the radio from Table 1.2 is to be used in place of the amplifier output power. Cross referencing this EIRP (dBm) with that listed below will give the corresponding minimum separation distance for the given system.

Purpose The purpose of this annex is to demonstrate that Hyperlink Technologies’ HA2401-AGCXXXX AGC amplifiers have no emissions variations over a wide range of input power levels. 2. Amplifier Construction The HA2401-AGCXXXX amplifiers can be broken down into two categories, each with a different construction and schematic. The low power type, HA2401-AGC010 to HA2401- AGC250, and the higher power HA2401-AGC-250 to HA2401-AGC1000. (The extra dash in the HA2401-AGC-250 is used to discriminate it from the equivalent powered HA2401-AGC250 at this time.) Depending on the filing, one or the other type of amplifier is of concern; both are included herein. A detailed block diagram and schematic, Exh 05 – Schematics(Amplifiers).pdf, has been filed as a confidential part of this submission. Detailed information regarding the construction of these amplifiers and an explanation of their implementation relating to this matter is included in that portion of the filing. This information has been deemed CONFIDENTIAL by Hyperlink Technologies, and is therefore not included here. 3. Measurements For six configurations of the HA2401-AGCXXX amplifiers, the devices were tested for output power and conducted emissions with regards to the FCC and IC limits. The flowing graphs and tables include the results of these measurements. Plots of the conducted measurements follow. (All tests in this ANNEX were performed using the LUCENT Radio, FCC ID: IMRWLPCEL4H.) Because of the physical construction of the amplifiers, as described in Section 2 of this annex, amplifiers intermediate to those tested will also demonstrate the characteristics measured below. 2 1.1 Antenna Output Power vs. Cable Attenuation / Cable Length For this measurement, the configurations were set in a test mode for continuous data transmission. A peak (diode detector) power meter was connected where the antenna attaches to the system. Since the DUT transmits in continuous mode, there is no adjustment needed to the readings. As seen in the following figures, the HA2401-AGCXXX amplifiers’ output power ratings remain within 0.5 dB of there initial value for up to 10 dB cable attenuation between the LUCENT radio and the amplifier. A measurement of the WBC400 cable used in testing maintains a 3dB/50ft loss at 2.437 GHz, thus permitting 150 ft of WBC400 cable between the radio and the power amplifier before amplifier output power is compromised. Amplifier power is always maximum when no additional cable is used in the system.

Conducted Emissions Measurements Configurations Tested: The six configurations in Table 1 were determined to be a representative sample because of the physical construction of the amplifiers, as described in Section 2 of this annex. Again, amplifiers intermediate to those tested will also demonstrate the characteristics measured. Table 1.

The spectrum analyzer was connected where the antenna attaches to the system. The analyzer was set for RBW=VBW=100 kHz, SPAN=100 MHz. The 6-dB bandwidth was measured for lowest, middle, and highest channels available for use. The results for the configurations measured are summarized below. HA2401-AGC010 with 0 dB attn. Frequency 6 dB Bandwidth 2.412 GHz 10.0 MHz 2.437 GHz 9.6 MHz 2.462 GHz 10.1 MHz HA2401-AGC250 with 0 dB attn.

Frequency 6 dB Bandwidth 2.412 GHz 10.2 MHz 2.437 GHz 10.1 MHz 2.462 GHz 10.1 MHz The introduction of attenuation between the radio and the AGC amplifier(s) does not affect the Channel Bandwidth in such a way as to cause a violation of FCC or IC guidelines. 2.2 RF Antenna Conducted Spurious Emissions (15.247(c)) For this test, each configuration was put in a test mode for continuous data transmission. The spectrum analyzer was connected where the antenna attaches to the system. The analyzer was set for RBW=100 kHz, VBW=300 kHz, the frequency was swept from 0 to 25 GHz. In the plots, only the fundamental is seen, the rest is noise. In all cases, the noise is at least 35 dB below the carrier. (Limit -20.0 dB below carrier). The introduction of attenuation between the radio and the AGC amplifier(s) does not affect the Conducted Spurious Emissions in such a way as to cause a violation of FCC or IC guidelines. 2.3 Power Spectral Density and Line Spacing (15.247(d)) For this test, each configuration was put in a test mode for continuous data transmission. The spectrum analyzer was connected where the antenna attaches to the system. The spectrum was first scanne…
