FCC ID:WQE5237001 Operational description The WiN51XX/WiN52XX ODU CPE is an IEEE 802.16‐2005 compliant wireless device for deployment of point‐to‐multipoint (PMP) and point‐to‐point (PTP) network architectures. The WiN51XX/WiN52XX ODU CPE is an outdoor device. The WiN51XX/WiN52XX ODU CPE is WiMAX Forum 802.16e Wave 2 (MIMO) certified subscribers. Each subscriber registers and establishes a bi‐directional data link with the base station sector controller. The base station is connected to the head‐end over IP Backhaul or via wireless channels. The outdoor CPEs are connected to the base station over wireless channels. The outdoor CPE is connected to the indoor residential gateway over Ethernet or coaxial networks. Frequency range: WiN5237, WiN5137‐AC, WiN5137‐DC: 3650 – 3700 MHz The CPE consists of the following modules: Base‐Band board – including the WiMAX 16e MIMO Base‐Band SoC (running the 16e MAC + PHY) plus the User Interface plus the analog front end that interface the RF module. Power Supply board– DC/DC power supply. Converts the 48VDC to the various voltages that are feeding the Digital and the RF modules RF board ‐ Single transmit dual receive module that modulate the analog WiMAX signal input from the Base‐Band modem to the high frequency RF output. Audio filter (Mobile Unit only) Chassis The WiN51XX/WiN52XX CPE uses time division duplexing (TDD) to transmit and receive on the same RF channel. This is a non‐contention based method for providing an efficient and predictable two‐way PTP or PMP cell deployment. All uplink and downlink transmission scheduling is managed by the base station. The modulation technique specifies how the data is coded within the OFDMA carriers. The base station supports QPSK, 16 QAM, and 64 QAM modulations. The RF Amplifier has Vcc=5.5V and DC current 0.6A.

FCC ID:WQE5237001 CBP Questionnaire for RuggedCom CPE 2.1. Unrestricted Protocol Description Address the key requirements for operation using unrestricted contention based protocol. Please note that this requires recognizing other systems (both similar to yours and different from yours) that operate on a co-channel. Indicate the strategy for sharing the spectrum in terms of: (1) Does the system use spectrum sensing to determine if the other devices are transmitting and then find ways to share the bandwidth, or (2) Does the system have some other strategy? Answer: The FCC mentions the WiMAX technology as an example of restricted contention protocol: “34. Under the Commission’s rules, contention-based protocols can be broadly categorized as either “unrestricted” or “restricted.” ... Restricted contention protocols can prevent interference only with other devices incorporating the same protocol. WiMAX, with its scheduling protocol, currently stands as the main example of a restricted contention technology. In its present format, WiMAX technology effectively prevents interference among multiple transmitters on a single WiMAX system. Different WiMAX systems can be coordinated to avoid interfering with each other, thus providing each WiMAX device a “reasonable opportunity to operate.” (FCC 07-99). WiMAX Protocol Brief: WiMAX MAC protocol is a centralized protocol in which the base station controls access to the air interface. In the downlink, all decisions related to the allocation of bandwidth to various MSs are made by the BS, which does not require the involvement of the MS. As packets arrive for each terminal, the BS schedules them for the PHY resources, based on their QoS requirements. Once dedicated PHY resources have been allocated for the transmission of the MAC PDU, the BS indicates this allocation to the MS, using the specific MAC messages. In general, WiMAX terminal is a slave to the BS. In the uplink, the MS requests resources by using a contention bases protocol. WiMAX uses a truncated binary exponential back off algorithm for contention-resolution during polling of user terminals. When it needs to send a bandwidth request the MS first enters a contention resolution phase, if selecting a uniformly distributed random number between 0 and BACKOFF WINDOW. This random value indicates the number of transmission opportunities—allocated resources for multicast/broadcast poll—the MS will wait before sending its bandwidth request. BACKOFF WINDOW is the maximum number of transmission opportunities an MS can wait before sending the pending bandwidth request. If it does not receive a bandwidth allocation based on the UL MAP message within a time window specified by a timer, the MS assumes that its bandwidth request message was lost, owing to collision with another MS, in which case MS increases is back off window and repeats the process. If bandwidth is still not allocated after a maximum number of retries, the MAC PDU is discarded. FCC ID:WQE5237001 Spectrum Sensing In addition to the standard WiMAX CBP, the BS is equipped with interference level sensor which is able to sense the presence of other systems in the frequency operation. In WiMAX the BS and MS communicate in the master – slave mode, where BS is the master and MS is the slave. Thus, the signals transmitted by the MS are controlled by the BS. 2.2. Threshold detection to determine occupancy 2.2.1. Describe how your system determines if another system is using the spectrum. At what detection level – relative to 0 dBi receive antenna gain (busy channel threshold), does the device determine if another system is operating on the spectrum? Answer: In WiMAX CPE operation is controlled by the BS via the DL and UL maps passed from the BS to MS. The BS product is designed to listen to the environment signals by HW means and detect their power. Once the detected power is higher that a predefined threshold it is decided that there is another system operating in the same spectrum. The threshold is configurable and its default value is -90 dBm. 2.2.2. How long does the system observe to determine if the channel is busy – at the initial time and in between communications? Answer: The spectrum is observed in between communications in time periods in which the system is silent, which are the TTG and RTG gaps (the duration of each gap is about 50 microseconds). 2.2.3. What is the bandwidth being monitored versus bandwidth occupied for all modes of operation? Answer: The whole occupied bandwidth is being monitored. 2.2.4. How much variability is provided to the system operator to adjust busy channel detection threshold? Answer: The detection threshold is configurable by the operator. Its range is -90 to-45 dBm. 2.2.5. What is the operating system threshold (receive threshold) compared to the monitoring threshold (busy channel threshold)? Answer: The default monitoring threshold is approximately the same as the receive threshold. 2.2.6. What additional checks does the system perform to determine if the spectrum is being used before initiating a transmission? FCC ID:WQE5237001 Answer: None. 2.2.7. Does the master and the client perform the threshold detection? If master only performs the detection how does it determine if the client may interfere with the other system (hidden node detection mechanism)? Answer: In WiMAX the downlink and uplink transmissions are controlled by the master (BS). In case that the master transmission is disabled the slaves (CPEs) cease the transmission as well. 2.3. Action taken when occupancy is determined Answer: In case that another system is detected in the spectrum, the transmission of the BS is ceased for a predefined period of time. This will cause the MS to cease the transmission as well, due to the fact that it will not receive the UL map from the BS. 2.3.1. What action does your system take when it determines occupancy? Does it vacate the channel or does it have some back-off and retry strategy? What is the impact o…

Ruggedcom Ltd. FCC ID:WQE5237001 Page 1 of 1 Environmental evaluation and exposure limit according to FCC CFR 47part 1, §1.1307, §1.1310 The calculation was done for required safe distance (the device is classified as fixed). Limit for power density for general population/uncontrolled exposure is 1 mW/cm 2 for 1500 -100000 MHz frequency range: The power density P (mW/cm 2 ) = P T / 4 r 2 , where P T is the maximum equivalent isotropically radiated power (EIRP). The peak output power of 18.01 dBm with 18 dBi antenna gain corresponds to the equivalent isotropically radiated power (EIRP) of 18.01 dBm + 18 dBi = 36.01 dBm, which is equal to 3990 mW. The minimum safe distance “r”, where RF exposure does not exceed FCC permissible limit, is r = sqrt { P T / (Px4)} = sqrt {3990 / 12.56} = 17.8 cm  2 m .
