November 12, 1998 FCC Product Description Page 1 of 5L5X-PMP-04-280 POINT-TO-MULTIPOINT PRODUCT DECRIPTION 1.0Overview P-COM, Inc., an ISO-9001 certified company, develops, manufactures and markets millimeter-wave radio systems and wireless solutions for wideband and broadband services for the worldwide telecommunications industry. These systems provide a high quality, cost-effective digital transmission solution for short-haul applications and for a variety of wireless services. These systems have been developed to meet all relevant industry standards. P-COM's Point-to-Multipoint (PMP) system meets the crucial requirements of minimizing the user's cost of ownership. The design philosophy that governs all P-COM product development decisions is one which results in a product that is high in reliability, cost- effectiveness and simple to install and maintain. Given the competitive nature of the telecommunications service industry, these attributes play a key role in the successful and profitable operations of users wireless networks. The system provides wideband and broadband services for business customers. These services include telephony, data, LAN, and video. The system also provides solutions for Fixed Wireless Access (FWA), Wireless Local Loop (WLL), Local Multi-Point Communications Services (LMCS) and Local Multi-Point Distribution Services (LMDS). Employing an integrated star topology, the Point-to-Multipoint (PMP) system uses digital wireless cell-based transmission to carry both wideband telephone services and broadband multimedia services to customers. Minimal delay is provided for voice traffic and very low Bit Error Rates are achieved to support data services. The unique architecture of the PMP system has the following benefits: • Flexibility • Scalability • Bandwidth management • Integrated Network Management • Software Distribution • Wide variety of User Interfaces • Wide range of frequency bands available: 10 - 40 GHz November 12, 1998 FCC Product Description Page 2 of 5L5X-PMP-04-280 2.0System Architecture The wireless Point-to-Multipoint system addresses the requirements for alternative access to local circuit, packet and cell switching facilities within metropolitan areas. It interfaces with existing PABX, host computers, LANs, Multiplexers, Routers/Bridges, etc. and provides transport to local switching centers via a highly reliable, wireless communications link. The PMP network is composed of one or more Base Stations that are strategically located within the desired coverage area (i.e., city). Each Base Station supports Line-of-Sight connections to Customer Premise Terminals (CPT). The Base Station multiplexes all traffic onto one or more continuous carriers that are transmitted to the CPTs. These carriers are typically transmitted at slightly different frequencies to avoid interference. On the upstream direction the CPTs use Frequency Division Multiple Access (FDMA) method to transmit information to the Base Station. The CPTs each communicate on separate carriers with demodulators at the Base Station. The system is designed for rapid fault isolation and repair in the field. All active elements are contained on front-loaded cards with front-mounted LEDs indicating status. The system makes extensive use of cell transport over the wireless link between the Base Station and the CPTs. It efficiently supports traffic such as T1, Fractional T1, ISDN, analog voice, Frame Relay and Nx64 Kbps data. 2.1Base Station The Base Station is composed of an independent set of sectors each providing up to 90 ° coverage within the 360 ° area around the Base Station. Each Base Station also interfaces to the Public Switched Network (PSN) through concentrated access links. Each Base Station can support multiple sectors. Sectors are composed of one or more Indoor Units (IDUs) and an integrated RF/Antenna Outdoor Unit (ODU). The RF/Antenna ODU contains lensed-horn antennas. Each sector antenna contains a transmit and a receive horn. The IDU is a standard rack-mount chassis with redundant power supplies, and space for plug-in cards. 2.1.1 Sector The Sector supports FDMA CPTs and provides complete connectivity to the backbone for transport to the service node and/or PSN. A sector consists of up to four sector subsystems connected to a Hub IF Combiner that combines the IF signals from each of the sector subsystem onto a single IF cable connected to the ODU. Each Sector consists of the following components: • One Outdoor Unit (ODU) containing the RF components and the antenna • One Hub IF Combiner November 12, 1998 FCC Product Description Page 3 of 5L5X-PMP-04-280 • Up to four Indoor Units (IDU) each containing Modulators, Demodulators, Sector Controllers, and T1-Network Interface Cards • An Inter-facility Link (IFL) consisting of one coaxial cables connecting the Hub IF Combiner to the ODU 2.1.2 Hub IF Combiner The Hub IF Combiner is a rack-mount unit that connects up to four IDUs to a single ODU. The IDUs are connected to the Hub IF Combiner with a single coaxial. The Hub IF Combiner combines all four IF signals onto a single coaxial cable to the ODU. The Hub IF Combiner also multiplexes 10 MHz reference and DC power for the ODU on this cable. 2.1.3 Sector Outdoor Unit The Sector Outdoor Unit (ODU) is a single integrated enclosure containing all RF components mounted directly to a receive horn antenna and a transmit horn antenna. The ODU transmits modulated RF signals to the CPTs and receives RF signals from the CPTs via line-of-sight wireless communication links. 2.1.4 Sector Indoor Unit The Sector IDU is located indoors at the Base Station site and is connected to the Sector ODU via IFL cables. The Sector IDU is comprised of the following components: • Rack mount Chassis with Power Supplies • Modulators • Demodulators • Sector Controller • T1 Network Interface Cards (NICs) The Base Station Chassis provides space for Modulators, Demodulators, Sector Controllers, and T1-NICs. 2.1.5 Interconnect…
