1-1 1.1 EQUIPMENT DESCRIPTION 1.1.1 Equipment Versions This manual covers the following radio port equipment versions: • Radio Port Unit, RPU, and the associated antennas and mounting accessories. The RPU can be ordered for operation in the following frequency bands: 2.4 GHz and 3.5 GHz. • Radio Port Coupler, RPC, performs the RPU functions with an internal antenna. The RPC can be ordered for operation in the following frequency bands: 2.4 and 3.5 GHz. Figure -1 shows a general view of typical basic RPU and RPC units. Figure -1. Typical RPU and RPC Units, General View 1.1.2 RPC Description 1.1.2.1 RPC Functional Description The RPC is a complete radio port subsystem, which contains the RPU hardware, an internal 60° sectorized antenna and an antenna coupler, that enables connection to another RPC or to an external antenna, for space diversity. Therefore, the RPC simplifies the installation process, reduces the resources and environmental impact relative to typical RPU-based installations, and improves the appearance of the radio base station. The RPC is offered in the following version: • RPC without reflectors for the 2.4 and 3.5 GHz frequency bands. 1.1.2.2 RPC Functional Block Diagram The functional diagram of the RPC is shown in Figure -2. The RPC uses PLI and PRC modules whose functionality is similar to that of the corresponding RPU modules, an internal antenna, and a PC module that includes the transceiver functions of the PRM module used in the RPU, with the addition of a coupler. The coupler is used only in the dual-RPC base station configuration (see para. 1.1.2.5), in which the RPC2 connectors of two RPC units heading in the same direction are cross-connected using two coaxial cables. Space diversity is obtained for each RPC by coupling the internal antenna of the other RPC. The dual RPC configuration supports up to 16 simultaneous calls. RPU RPC Radio Port System Installation and Operation - Introduction 1-2 1.1.2.3 Frequency Oscillators The modules of the RPC contain several frequency generation circuits. The PLI module contains crystal of 15.36MHz. The RF Module (namelt the PC module) contains the following crystals: 14MHz, 56.238MHz. The PRC module contains crystal of 24MHz. 1.1.2.4 Hopping Frequencies sequences list The RPC operates at pseudorandomly hopping frequencies scenario. Upon installation, desired frequencies are loaded to the frequency table in the radio digital memory. Number of frequencies are any combination of more than 75 frequencies in the range of 2400 MHz to 2480MHz. The system assigns a pseudorandomly frequencies order for the radio hops. The order of hops is kept the same all the time after installation.

RPC Functional Diagram In addition, the RPC can be used with external antennas: • An additional (standard) RPU antenna can be connected to the second connector of the RPC. • For special applications, e.g., for omni-directional coverage or when special antennas are needed, or to support antenna diversity when transmitting on a 3.5 GHz RPC, two external antennas shall be used. In this case, the internal antenna of the RPC can be disconnected in the field and the internal connector can be directly connected to one of the external RF connectors. 1.1.2.5 RPC Configurations This section presents basic configurations using the RPC capabilities. 1.1.2.5.1 Dual-RPC Radio Base Station This configuration, shown in Figure -3, includes two radio base stations, heading in the same direction (Figure -3 shows units without external reflectors: such reflectors are used only with the 1.5 GHz units). The internal antenna of each RPC is used as the second antenna for the other RPC, so that space diversity is obtained for both RPC’s. This configuration, which requires only two units, replaces six units (two RPU’s and four antennas). As a result, it is possible to install four RPC-based radio stations on one H-support. Eventually, installation costs are reduced and environmental and aesthetic impact is minimized. Every installation including multiple radio base stations, heading in the same direction, will include pairs of RPC’s connected according to Figure -3. Figure -3. Dual RPC Configuration 1.1.2.5.2 Single RPC Radio Base Station with Space Diversity A single radio base station with space diversity comprises an RPC and a sectorized antenna. A single cable connects the two units. Both the internal and external antennas are connected via the antenna coupler in the RPC. Radio Port System Installation and Operation - Introduction 1-5 Figure -4 shows a typical RPC radio station. This configuration is used for the installation of a single radio base station, and for the single radio base station left at a location that includes an odd number of radio base stations, heading in the same direction. Sectorized Antenna RPC Figure -4. Single RPC Radio Station 1.1.2.5.3 External Antenna Options The RPC enables the connection of a pair of external antenna pairs (e.g., omni-directional or wider beam-width antennas), whenever needed. To use this option, it is necessary to change internal connections in the RPC. External antennas must always be used on a 3.5 GHz RPC, when it is necessary to use antenna diversity in the transmit mode.

Memorandum 1 To: Hermon Labs. InnoWave Wireless Systems 4 Hashiloach Street Petach Tikva 49104 Israel From: Amnon Beer Tel: (972-3) 926-3507 Fax: (972-3) 926-3652 Subject: RPC Associated Receiver Compliance Information. The Radio Port & Coupler (RPC) unit is working in TDMA mode. Both receive and transmit frequencies of the radio are set to the same frequency at each hopping frequency for 2mSec. At the first 1mSec, the RPC’s receiver is activated, and data from the subscriber radio is received by the RPC, after one millisecond, the receiver is deactivated. After deactivation of the receiver, the radio remains at the same frequency, and the transmitter is activated. The transmitter transmits data to the subscriber radio for another 1 millisecond. After completion of 1millisecond receive period, and 1 millisecond of transmit period, the radio software controls the RPC to change frequency to the next hopping frequency. After the RPC has been settled to the new frequency another receive and transmit cycles start for 2 millisecond as described. According to this procedure, the receiver and the transmitter of the RPC, share the same frequencies all the time. Sincerely Amnon Beer
