EkoCel  provides system coverage enhancement by remoting the base station RF receive and transmit via a fiber optic connection to a location requiring coverage. EkoCel is designed to meet or exceed applicable base station and FCC emission standards. The EkoCel enhanced specifications provide minimal impact to the overall system performance. EkoCel is comprised of two major components the Microcell (Remote) Unit, which is remotely located in the area being provided service and the Hub Unit, which is located at the base station. EkoCel will support multiple RF channels on all PCS system formats and up to 24 channels for AMPS Cellular. Several options are available including, Wave Division Multiplexing (WDM), diversity receive, battery back up and duplex interface at the base station. EkoCel is supplied in all of the PCS bands A to F and is also available in a dual band operation configuration. The dual band unit will support both 1.9 GHz PCS and 800 MHz Cellular system over the same fiber optic cable. EkoCel is designed to meet the service provider requirements for Operations, Administration, Maintenance and Performance (OAM&P). Alarm and control of the system is accessible at the Microcell hub, remote unit or via a telephone (wire or wireless) modem connection. Relay contacts also allow the user to remote the alarms with the base station alarm system with user defined contacts. This allows the service provider to have instant alarm notification at the Network Operation Control Center (NOCC) without additional specialized hardware and software, commonly referred to as an Element Management System. This provides simplicity and cost savings to the user. Both the hub and the microcell remote are equipped with a display and function keypad allowing the user easy access to alarms and system controls without additional equipment. Three levels of security are provided to prevent unauthorized access to the system. EkoCel has a patent pending self-set up and system control feature that will allow the system to automatically set up for the user defined system requirements. EkoCel automatically adjusts gain and power based on the number of RF channels, system format, system input power and optical loss. The system continues to monitor system performance and alert the user of any system changes that requires additional real time compensation. EkoCel was developed specifically for use as a fiber optic microcell. It specifically…

FCC ID:NUWØ5ØCEKO8 1 CI WIRELESS 800 MHZ CELLULAR BAND EKOCELL REPEATER SYSTEM DESCRIPTION OF OPERATION 1.0 BASIC DESCRIPTION The EUT is a 50 watt 800 MHz Cellular Band Repeater System. This system is a U.S. Cellular band repeater system which enhances the coverage of a cellular 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 system health & report/record any EUT problems. The CI Wireless 800 MHz Cellular Band 50 watt Repeater supports CDMA, TDMA and AMPS communications in the U.S. cellular band. 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 800 MHz Cellular Band 50 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 50 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:NUWØ5ØCEKO8 2 3.0 SYSTEM CONFIGURATION(S) The two models for the system components tested are: Hub Unit:Eko-8H0B0-DB0000 Remote Unit:Eko-8M0CR-DAC000 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-8HXB0-XXXXXX for the Hub unit and Model Eko-8MXCR-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.
