Many buildings are constructed of materials like metal, brick and concrete that attenuate cellular telephone signals. Symptoms such as dropped calls, broken audio and static indicate the need for an in-building repeater. The SignalReach TM CR100 Small Office Home Office (SOHO) Cellular Repeater extends cellular services into buildings, parking garages, tunnels and other poor coverage areas. The CR100 is designed for use with 800MHz cellular telephones and offers a cost-effective solution for small business and residential applications. The repeater is useful in areas where cellular service is available outside of the building but marginal indoors. The SignalReach TM CR100 is a stationary device that automatically reradiates signals from the base transmitters without channel translation, for the purpose of improving coverage of existing service by increasing the signal strength in dead spots. The repeater is a network-compatible device that amplifies cellular signals in both the uplink and downlink directions. The repeater is simple to install, and contains circuitry to ensure proper operating power levels, and as well, includes an automatic feedback and detection circuitry that detects, as a result of poor isolation between the subscriber and donor antennae. In this condition the repeater will adjust it’s gain to compensate for the abnormality, and warn the user through a visual indicator LED. The CR100 will enhance the cellular telephone user’s experience while complying with cellular network specifications. Linear operation is guaranteed under all conditions. The CR100 allows up to two indoor antennas to be used without the need of external components. Its auxiliary indoor antenna port allows a second indoor zone to be easily connected. The repeater can be powered by its AC adapter or through the in-building primary subscriber antenna port using an optional power inserter. Threshold of handset recei ver: -104dBm Base Station Signal strength outside buildi ng -90dBm Actual received power: as low as -130dBm (too low for handset) Building material attenuates signal by 10 to 40dB Threshold of handset recei ver: -104dBm Base Station Signal strength outside buildi ng -90dBm Actual received power: as low as -130dBm (too low for handset) Building material attenuates signal by 10 to 40dB This product is designed for installations where cellular coverage is available outside the building, and indoor coverage is inadequate. CR100 Features: • Easy Installation – No calibration required • Automatic feedback detection and warning circuitry • Auxiliary in-building antenna port provides enhanced coverage • Up to 20000sq.ft of free space coverage with only one interior antenna • Network-compatible operation • Auto levelling circuitry ensures linear operation • FCC approved • Optional power inserter available • External fault output signal Functional Description & Operation The repeater works on the principle of receiving the handset signal through a subscriber (indoor) antenna, amplifying or ‘boosting’ its signal level, and then passing it on to the donor antenna located outside the building. Signals from the cellular tower (downlink) are also amplified and passed to the subscriber antenna. Threshold of handset recei ver: -104dBm Base Station Signal strength outside buildi ng at antenna: -90dBm In-buildi ng repeater provides 40 dB gain Actual recei ved power (with losses inside building): -95dBm (10 dB ma rgin ) Threshold of handset recei ver: -104dBm Base Station Signal strength outside buildi ng at antenna: -90dBm In-buildi ng repeater provides 40 dB gain Actual recei ved power (with losses inside building): -95dBm (10 dB ma rgin ) Arrista’s CR-100 in-building repeater is a Class B Broadband device, it will process the entire cellular 800MHz spectrum. Input and output duplexers and band pass filters in the downlink and uplink path provide the repeater’s filtering and isolation. The maximum gain in each of the downlink and uplink path is 60dB. Both the downlink and uplink paths incorporate automatic gain/level control, to ensure that downlink and uplink power amplifiers are not overdriven and operate free of distortion. As well, the automatic gain/level control ensures that in normal operation the downlink and uplink gain mirror each other. The CR100 also has primary and secondary subscriber ports, allowing the repeater to double the in-building coverage area. Installation Procedure The repeater unit should be installed in a sheltered area, it’s operating temperature range is extensive, but is not sealed to prevent water (rain) ingress. The repeater unit should not be installed in an area where the ambient temperature is expected to exceed +60°C. The indoor and outdoor antenna locations must be chosen carefully to avoid re-generative feedback. Re-generative feedback occurs when the subscriber antenna picks up the donor antenna transmit signal. A general rule of thumb is to locate the antennae where the isolation is at least 10 dB greater than the operating repeater gain. The Arrista repeater has a maximum gain of 60dB in uplink path, as a result, the isolation required between the subscriber and the donor antenna is in a range of 70dB. The line of sight separation between the subscriber and do…

RF EXPOSURE Test Type: Maximum Permissible Exposure FCC Para No.: 1.1310, 2.1093 Tested By: Paul Eberling Date: January 13, 2004 1.9.5.1. SPECIFICATION REQUIREMENT: As per FCC 47CFR§1.1301; FCC OET Bulletin 65, 97-01 “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields” and FCC OET Bulletin 65, Supplement C, 01- 01, “Additional Information for Evaluating Compliance of Mobile and Portable Devices with FCC Limits for Human Exposure to Radiofrequency Emissions”, for transmitters operating in the 824-849 MHz range, paragraph 1.1310 Table 1 limits maximum permissible exposure (MPE) to f/1500 mW/cm 2 for uncontrolled environments and f/300 mW/cm 2 for controlled environments. The far field on-axis power flux density (W/m 2 ) is calculated using the following formula: S = G P T / 4πR 2 [6] Where: S = Power density (in appropriate units, e.g. mW/cm 2 ) G = Power gain of the antenna in the direction of interest relative to an isotropic radiator P T = Power input to the antenna (in appropriate units, e.g., mW) R = Distance to the center of radiation of the antenna (appropriate units, e.g., cm) It is important to note that the power gain factor, G, in Equation (1) is normally numeric gain. Therefore, when power gain is expressed in logarithmic terms, i.e., dB, a conversion is required using the relation: G=10^(dB/10) [7] For example, a logarithmic power gain of 14 dB is equal to a numeric gain of 25.12. 1.9.5.2. CR100 C ELLULAR SIGNAL AMPLIFIER PARTICULARS The following table shows the maximum downlink output power of the signal amplifier combined with an antenna with 9dBi gain. This is the maximum antenna gain permissible for the downlink signal as documented in the user/installation manual. The following table also shows the maximum uplink output power of the signal amplifier combined with an antenna with 18dBi gain. This is the maximum antenna gain permissible for the downlink signal as documented in the user/installation manual.
