Operational Description

FCC ID:NUWØØ8EKO19 1 CI WIRELESS 1900 MHZ PCS BAND EKOCELL REPEATER SYSTEM DESCRIPTION OF OPERATION 1.0 BASIC DESCRIPTION The EUT is an 8 watt 1900 MHz PCS Band Repeater System. This system is a U.S. Cellular band repeater system which enhances the coverage of a 1900 MHz PCS system by adding base station capability to traditional poor cellular coverage areas (i.e. subways, shopping malls, convention centers). The system has a set of automatic setup features, enabling the repeater to be installed & configured by one person. Automatic system monitoring is present to monitor sysetm health & report/record any EUT problems. The CI Wireless 1900 MHz PCS Band 8 watt Repeater supports CDMA, TDMA and AMPS communications. The EkoCell system is comprised of two components: a Hub unit and a Remote unit. The Hub is installed at a cellular base station while the remote unit is installed at the desired transmit/receive location and attached to an antenna assembly. The two pieces are connected by two fiber optic links (one for transmit, one for receive). Due to the low loss of the fiber link, the Remote is usually not installed at the same location as the Hub unit. 2.0 RF THEORY OF OPERATION The CI Wireless 1900 MHz PCS Band 8 watt Repeater operates in two basic modes of operation simultaneously: transmit and receive. When installed, the Hub portion of the EkoCell is connected in to a standard base station for the cellular system. The Remote Unit is then installed at a location up to 10 kilometers away from the base station. In the transmit mode of operation, the Hub taps the RF signals from the base, routes the signals through an RF modem, then feeds the output of the RF modem into a fiber optic modulator. The fiber optic modulator contains a solid state laser and optic receiver. The output of the laser is fed via a multimode fiber optic cable to the Remote Unit. When the signal arrives at the Remote Unit, the signal is received by another fiber optic modulator, fed to an RF Modem, then routed to an amplifier. The output of the power amplifier is regulated to maintain a 4 watt output level. The output of the amplifier is fed to a duplexer (with lightning protection) then to the antenna port for transmission. In the receive mode of operation, the mobile signals are received from the antenna port on the Remote Unit, routed through the duplexer, then boosted and filtered by a low noise amplifier/band pass filter assembly. This signal is modulated by the RF modem, fed to the Remote Unit fiber optic modulator, then transmitted back to the Hub Unit. The Hub Unit receives the optical signal and reconstitutes the original mobile signal. This signal is then fed to the base station circuitry. The system does perform RF pre-emphasis on the signals to correct for transmission losses. FCC ID:NUWØØ8EKO19 2 3.0 SYSTEM CONFIGURATION(S) The two models for the system components tested are: Hub Unit:Eko-1.9HOBO-OAC000 Remote Unit:Eko-1.9ROBO-OAC000 The test covered under this report address all subseries of these models. The base model designators for the components of this system are Model Eko-1.9HXB0-XXXXXX for the Hub unit and Model Eko-1.9RXB0-XXXXXX for the Remote Unit. See attached sheet for model designator definitions. The two particular models used for this test were loaded with all active circuit options available, providing a worst case configuration for emissions testing. To cover the 1930 to 1965 MHz frequency range, the CI Wireless Inc., 1900 MHz PCS Band 8 Watt Repeater may be configured (via the selection/specification of the internal filter) to operate in one of three PCS Bands (Bands A, B and D). Each EkoCell can only be configured to operate in one band at a time; changing the EkoCell to a different band requires a change in the filter portion/duplexer of the Remote Unit (no changes to active circuits are required). To verify compliance with the Rules for all three bands, full testing was performed (three points per band for each modulation type) for each band. FCC ID:NUWØØ8EKO19 3 CONFIGURATION INDEX

Test Report

1 REPLY TO REQUEST FOR ADDITIONAL INFORMATION CI WIRELESS 1900 MHZ PCS BAND 8 WATT REPEATER FCC ID NUW008EKO19 Submission Number: EA93341 Correspondence Number: None April 1999 This document has been compiled to reply to two of questions posed by the FCC as part of the Equipment Authorization Process for the CI Wireless 1900 MHz PCS Band 8 Watt Repeater (NUWØØ8EKO19). Each of the questions listed by the FCC is listed prior to the reply. Question 1) If the unit is intended to handle multiple channels, then you should submit three signal intermodulation tests for each emission kind. Answer Based on a conversation between Frank Coperich of the FCC and John O’Brien of Professional Testing, this test is a single test using three emission types of the same kind (i.e. three CDMA signals on three separate CDMA channels). The intent of this test is to determine if intermodulation products generated by multiple carriers will generate products which are over the conducted spurious emission limits. While this test is not documented in the Rules, it is a requirement for multiple channel equipments. Based on the conversation with Mr. Coperich, the test configuration of this test should be: (1) Configure 3 signal sources using the same modulation type to provide a multiple channel signal to the device. The recommended channel settings are: (a) One channel at the lowest allowed frequency in the band (b) One channel at the highest allowed frequency in the band (c) One channel at either the 3 rd lowest or 3 rd highest channel setting. This will provide a 1 channel guard band from the end channel. The total power for combined output signal should be maximized to the power rating of the EUT. All input channel settings should be equal. (2) Measure (or plot) all intermodulation products inside and outside the allowed channel band. All intermodulation products must meet the 43 + 10 log (P) requirement for spurious emissions. This figure should come out to a maximum intermod (or spur) level of -13 dBm. Most measurements of the intermod levels are made using a peak method, however, fully accurate measurements of the intermod levels should be made using the following detection methods: 2 Modulation TypeDetector/Measurement Method GSMPeak TDMA (NADC)Average CDMAAverage Repeat this test for all modulation types which the EUT will be licensed/authorized for. ALTERNATE METHOD: Due to the difficulty in providing three identical fully modulated signals, a method using two intermodulation sources (rather than 3) is allowed. The test should be configured in the following manner: (1) Set one carrier to either the highest or lowest allowed channel in the band. (2) Set the second carrier two channels away from the first channel (this will either be the 3 rd highest or lowest in the band, again providing a one channel guard band). (3) Configure the output power for the signals such that the total output power is at the maximum rating of the EUT. Also, verify that the input levels for all signals are equal. (4) Measure (or plot) all intermodulation products inside and outside the allowed channel band. All intermodulation products must meet the 43 + 10 log (P) requirement for spurious emissions. This figure should come out to a maximum intermod (or spur) level of -13 dBm. Most measurements of the intermod levels are made using a peak method, however, fully accurate measurements of the intermod levels should be made using the following detection methods: Modulation TypeDetector/Measurement Method GSMPeak TDMA (NADC)Average CDMAAverage (5) Repeat this test for all modulation types which the EUT will be licensed/authorized for. The two channel method was used for this test. Plots of the data for this test are shown in the Appendix. Question 2) Please clairify the power output power ratings for multi-channel operation. Answer The total composite power for this device is 8 watts. The EUT has a power regulation system which will reduce the total individual channel power for the carriers to provide a constant 8 watt composite power regardless of the number of carriers. The worst peak power level is single channel operation, which results in a peak output power of 8 watts (composite power divided by 3 1). As channels are added to the EUT, the individual channel power is based on the composite power divided by the number of channels. For this reason, the individual channel powers used in the intermod test was 4 watts output per channel (8/2 = 4). 4 Intermodulation Appendix Product Data Sheets 5 Intermodulation Product Data Sheet CI Wireless, 1900 MHz PCS Band 8 Watt Repeater (FCC ID: NUWØØ8EKO19) SERIAL #: Not AvailableMODE: TDMA (NADC) DATE: April 18, 1999LINE MEASURED: Antenna DETECTOR FUNCTION: AveragePROJECT #: 99-219 COMMENT #1: Display Line Set to Limit of -13 dBm COMMENT #2: Cellular A Band TEST ENGINEER:______________________APPROVED BY:______________________ 6 Intermodulation Product Data Sheet CI Wireless, 1900 MHz PCS Band 8 Watt Repeater (FCC ID: NUWØØ8EKO19) SERIAL #: Not AvailableMODE: TDMA (NADC) DATE: April 18, 1999LINE MEASURED: Antenna DETECTOR FUNCTION: AveragePROJECT #: 99-219 COMMENT #1: Display Line Set to Limit of -13 dBm COMMENT #2: Cellular B Band TEST ENGINEER:______________________APPROVED BY:______________________ 7 Intermodulation Product Data Sheet CI Wireless, 1900 MHz PCS Band 8 Watt Repeater (FCC ID: NUWØØ8EKO19) SERIAL #: Not AvailableMODE: TDMA (NADC) DATE: April 18, 1999LINE MEASURED: Antenna DETECTOR FUNCTION: AveragePROJECT #: 99-219 COMMENT #1: Display Line Set to Limit of -13 dBm COMMENT #2: Cellular D Band TEST ENGINEER:______________________APPROVED BY:______________________ 8 Intermodulation Product Data Sheet CI Wireless, 1900 MHz PCS Band 8 Watt Repeater (FCC ID: NUWØØ8EKO19) SERIAL #: Not AvailableMODE: CDMA DATE: April 18, 1999LINE MEASURED: Antenna DETECTOR FUNCTION: AveragePROJECT #: 99-219 COMMENT #1: Display Line Set to Limit of -13 dBm COMMENT #2: Cellular A Band TEST ENGINEER:_______…
