PIDAIRSPAN-WIPLL2WippLL Radio

Installing the SPR This chapter describes the installation of the WipLL Subscriber Premises Radio (SPR), located at the subscriber's premises. Warning: Cables with exposed ends (i.e., not yet crimped) should be covered with protective polythene bags during external cable installation processes. Warning: As the system emits microwave radiation, a minimum distance o f 500 mm must be maintained from the front of the SPR. However, for the 700 MHz band (i.e. WipLL 700), when external antennas are used, a minimum distance of 800 mm must be maintained from the front of the device. Warning: To avoid electrical or fire hazard, connect the SPR to the powe r supply only after mounting the SPR and connecting data cables. Note: Usually, the SPR is initialized (i.e., configured with an IP address) at Airspan's factory. However, if the SPR has not been configured, see Section 10.5, “Connecting to a PC for Serial Configuration”, before mounting the SPR. 10 02030311-07 Airspan Networks Inc. 10-1 Installing the SPR Hardware Installation Guide Note: The digital portion of the transceiver 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 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 particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment on and off, the user is encouraged to try correct the interference by performing one or more of the following measures: - Reorientate or relocate the receiving antenna - Increase separation between the equipment and receiver - Connect the equipment to an outlet on a circuit different from that to which the receiver is connected - Consult the dealer or an experienced radio/TV technician for help Note: A minimum separation of 200 mm should exist between power and data cables. 10-2 Airspan Networks Inc. 02030311-07 Hardware Installation Guide Installing the SPR 10.1.

02030311-07 Airspan Networks Inc. 2-1 Safety Guidelines This chapter outlines safety guidelines when installing the AS WipLL system. Warning: The user and the installer should be aware that changes and modifications not expressly approved by Airspan Networks could void the user’s authority to operate the equipment. Warning: Never install equipment that is damaged. Warning: Only qualified personnel should be allowed to install, replace, and service the AS WipLL equipment. 2.1. Electrical Safety Guidelines Warning: Disconnect all power when installing. 2.1.1. Handling Electrostatic Devices Electrostatic devices are those devices that may be damaged by the inadvertent discharge of static electricity from a charged body. The risk of damage, due to electrostatic discharge (ESD) to a device, may cause the device to fail suddenly, or it may induce a partial defect within the device, which will cause subsequent premature failure. 2 Safety Guidelines Hardware Installation Guide 2-2 Airspan Networks Inc. 02030311-07 Static electricity can result from operators walking on floors, moving around on chairs, from the movement of operator's clothing or even casual brushing against racks, benches or walls. Airspan recommends the following guidelines to be adopted to minimize the risk of component failure due to electrostatic discharge to the device: „ AS WipLL devices are provided typically in see-through anti-static bags. Wherever possible, checking and inspection of a unit should occur without removing it from the bag. „ All operators shall wear the approved conductive overall. „ Where operators come into direct contact with any piece of electronic hardware, operators must wear an ESD-preventive wrist strap. All straps and cords should be tested using a Wrist Strap Tester prior to use. The wrist strap cords shall have a 2 Meg Ohm resistor fitted at either end. Wrist straps should be worn in direct contact with bare skin and not over clothing. Warning: To prevent ESD damage to AS WipLL devices, always wear an ESD wris t strap when handling these devices or coming into contact with internal components. 2.1.2. Grounding Only certain AS WipLL devices require additional grounding. AS WipLL devices that do not require additional grounding have grounding at the main supply outlet. The following table lists the AS WipLL devices’ grounding requirements. Table 2-1: AS WipLL grounding requirements Site AS WipLL device Grounding BSR Through the mains (via BSDU) BSDU Additional grounding required (grounding lug at rear end of chassis) Base Station BSPS Additional grounding required (grounding lug at rear end of chassis) CPE SPR Through the mains (via SDA) Hardware Installation Guide Safety Guidelines 02030311-07 Airspan Networks Inc. 2-3 IDR Through the mains 2.1.3. Lightening Protection Warning: Never install the equipment during stormy weather and lightening. AS WipLL devices comply with the Surge Immunity standard: EN 61000-4-5. AS WipLL devices are protected from lightening surges as the outdoor devices (BSRs and SPRs) are encased in a plastic chassis. Therefore, if lightening strikes the device, an electrical circuit cannot be completed, and hence, no electrical surge can occur. In addition, AS WipLL outdoor and indoor (SDA) devices provide high-speed data line protection against direct and induced transient over-voltages surges on the cables. This capability is provided by the fact that all AS WipLL devices are designed with TVS (transient voltage suppressor) components that maintain potential differences. However, for geographical areas that have above normal lightening activity, Airspan can supply a surge protector composed of a 15-pin D-type adapter with a grounding wire. Safety Guidelines Hardware Installation Guide 2-4 Airspan Networks Inc. 02030311-07 2.2. Installing AS WipLL Radios and Third-Party External Antennas Warning: For unlicensedbands, it is the responsibility of the person installing the AS WipLL system to ensure that when using the outdoor antenna kits in the United States (or where FCC rules apply), that only those antennas certified with the product are used. The use of any antenna other than those certified with the product is expressly forbidden in accordance with FCC rules CFR47 part 15.204. The installer should configure the output power level of antennas according to country regulations and per antenna type. Warning: Outdoor AS WipLL units and antennas should be installed ONLY by experienced installation professionals who are familiar with local building and safety codes and, wherever applicable, are licensed by the appropriate government regulatory authorities. Failure to do so may void Airspan’s AS WipLL product warranty and may expose the end user or the service provide r to legal and financial liabilities. Airspan and its resellers or distributors are not liable for injury, damage or violation of regulations associated with the installation of outdoor units or antennas. Warning: When using external antennas, the external antennas must not be co-located or operating in conjunction with any other antenna or transmitter. Warnings: 1) The device cannot be sold retail, to the general public or by mail order. It must be sold to dealers. 2) Installation must be controlled. 3) Installation must be performed by licensed professionals. 4) Installation requires special training. Hardware Installation Guide Safety Guidelines 02030311-07 Airspan Networks Inc. 2-5 Warning: For unlicensedbands, in accordance with FCC regulations, ensure that the external antennas provide an EIRP of less than or equal to 36 dBm to prevent interference with other radios operating in the unlicensed band. The EIRP is defined by the following formula: Max. Power Output + Antenna Gain - Cable Loss ≤ 36 dBm (EIRP) Airspan does not supply cables for connecting external antennas. It is the responsibility of the installer to provide the cable and ensure the cable characteristics (e.g. length and cable loss) enables adhere…

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 August 27, 2004 RE: Airspan Networks (Isreal) Ltd. FCC ID: PIDAIRSPAN-WIPLL2 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please provide a photograph or drawing that shows the location of the label on the device. 2) The frequency band in the operational description mentions 2402-2482 MHz, while the 731 form states 2402-2480, and the frequency hopping lists frequencies from 2403-2481. Which is correct. Please confirm which is correct and adjust the appropriate exhibits. 3) Please note that the hopping list does not meet the FCC’s definition of Frequency Hopping Systems for pseudo-random as given in 2.1. Also see attached FCC interpretation. The hop sets appear to be incremented by a simple increment and divisor. This is not allowed when approved as a FHSS device. 4) AC Powerline conducted emissions (15.107 for digital device, 15.207 while Transmitting) must be shown for the new limits (equivalent to CISPR 22) and in the frequency range of 150 kHz – 30 MHz. This has not been provided. 5) There appears to be 2 different models, with different output powers. Please confirm that the user can not adjust the output levels. Also, please confirm that that radios are identical in each model and that the only difference is software. 6) The RF exposure suggest that both models have an output power of 23.33 dBm, while the old test reports suggest this is only the case for the model BSR with 11 dBi gain antenna, and the SPR has a maximum output of 18.67 dBm with 15 dBi gain antenna. If the SPR can have an output of 23.33 dBm, then the previous report can not be considered valid for this model as the device was not tested at the maximum output level. 7) Given the current RF exposure exhibit, this device appears to exceed the defacto +36 dBm EIRP requirement for the SPR model and is therefore must be limited to point-to-point installations. However given the information in 6) above, this may not be the case. Please explain. 8) If the + 36 dBm EIRP is exceeded, the manual must include information regarding 15.247 (b)(3)(iii). Where can this be found? 9) The powers listed in the new SPR report are significantly higher than those in the older report (over 3 dB higher). It appears that the test results in the old report may not be considered valid as the EUT must be tested for all tests with maximum output power. 10) FYI.....The average time of occupancy is no longer based upon 30 seconds, but 0.4 * the number of channels. However calculations of the information provided show that the maximum average occupancy is 400 msec for both 79 and 62 channel modes of operation. Timothy R.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 September 24, 2004 RE: Airspan Networks (Isreal) Ltd. FCC ID: PIDAIRSPAN-WIPLL2 After a review of the submitted information, I have a few comments on the above referenced Application. 1) The operational description/theory of operation states this device may operate as either a frequency hopping TX or a hybrid, not exclusively as a hybrid TX. Note that there is a variety of ways to approve a hybrid system (attachment for hybrids from the FCC has been provided on previous occasions). Recently approved devices for Airspan included both a FHSS and hybrid mode. If this device can be used in a frequency hopping mode only, then in this mode of operation it must meet all the frequency hopping requirements. If it is to be hybrid only, then all exhibits need to clearly cite this and not reference the fact that it may be configured for frequency hopping mode only. 2) If this can operate in FHSS mode only, then there is also a concern that the bandwidth is greater than that normally allowed for 900 MHz FHSS systems. 3) If this is capable of only operating in frequency hopping mode, then there is the concern that the hopping list does not meet the FCC’s definition of Frequency Hopping Systems for pseudo-random as given in 2.1. Also see attached FCC interpretation. The hop sets appear to be incremented by a simple increment and divisor. This is not allowed when approved as a FHSS device. 4) There are issues with the output power. What will the final output power be for this device? Powers throughout all documents must be consistent. Because of the power issue, it can not be asserted what the final power will be. Additionally, if the power was only to be equivalent to the earlier reports, then this should be how the device was tested. This fact needs to clearly be given throughout the report. If the power is increased, then all affected tests must be performed. In this case since only the spectral density seems to be tested this way, we can accept the increase in power. However, the documentation, reports, etc. should clearly cite what the final power will be for both models. 5) RF exposure information should be based on the highest output power to be used. Please review and correct as necessary. There are certain manual and use concerns if the EIRP will be > 36 dBi per our previous comments. Please clarify. Timothy R.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 September 24, 2004 RE: Airspan Networks (Isreal) Ltd. FCC ID: PIDAIRSPAN-WIPLL2 After a review of the submitted information, I have a few comments on the above referenced Application. 1) The Technical Specification provided mentions the factory may set up for FHSS or Hybrid. It appears the device may not meet the FHSS mode requirements because of bandwidth issues. However, you are also requesting approval only on hybrid mode. Therefore, because the device is capable of both, but only one is being used, please have the applicant provide an attestation (on their letterhead) attesting to the fact that only hybrid modes will be manufactured. Because of the concern with output powers used in this application, please have the manufacturer attest that the maximum output power for the SPR will be 18.7 dBm and for the BSR 23.3 dBm. 2) RF exposure information should be based on the highest output power to be used. Please review and correct as necessary. It appears the BSR appears that it should be listed as 18.67, not 21 dBm. 3) FYI.....There are various ways to approve a hybrid system (FHSS only, DTS only, both FHSS and DTS, Hybrid). Please refer to the following important notes regarding the approval: a) under FHSS only rules – device does not meet bandwidth requirements b) under Hybrid rules – device must be a true hopping system but doesn’t meet pseudo- random hopping requirement. c) Under DTS only rules - This device does not appear to meet the 500 kHz requirement. d) Under mutually exclusive rules of FHSS and DSS – not applicable. Note: To be approved under hybrid rules (see attachment), the device must be considered a true frequency hopping system, including meeting the pseudo random requirements. Compliance to this has not yet been shown as per previous comments since the hop set appears to be incremented by a simple increment and divisor. Timothy R. Johnson Examining Engineer mailto: tj…
