Wireless LAN Bridge. PPC-1000 Gigabit Ethernet MM-wave Link.

In response to market demand for ultra-wide broadband communication equipment, ElvaLink offers a new PPC-1000 series of Gigabit Ethernet radios. The Gigabit ElvaLink radio bridge was designed for a wide range of applications such as mobile backhaul, business network, FSO backup, IP network and emergency recovery network.  It provides interconnection between remote LAN segments at ultra high speed and utilizes Gigabit Ethernet protocols, which is the evolving standard for switches and routers available from a variety of telecommunication equipment manufacturers.

    One full-duplex Gigabit Ethernet link provides 1.25 gigabit-per-second connectivity that is the equivalent of approximately 650 T1 lines or 1,000 DSL connections. The PPC-1000 product has 1000 Base-SX connections at each end of the wireless link and transparently establishes the link outputs. The resulting connection can replace a fiber-optics cable physically connected end-to-end. The wireless mm-wave Gigabit link provides fiber equivalent performance, reliability and security but with no high deployment cost associated with outdoor fiber installations. PPC-1000 links have remote management as well as parameter monitoring capabilities.

A twisted pair patch cable connected to any RJ-45 socket within the LAN will allow remote SNMP management and parameter control of a set of PPC-1000 links from a central location. The Gigabit Ethernet point-to-point millimeter wave radio links have been designed with compact parabolic Cassegrain antennas of 30 and 60 cm diameters. The 60 cm antenna has a 0.4° beam width and 50 dB antenna gain parameters. PPC-1000 equipment has been offered as a comprehensive link kit with antennas, mounting units and accessories to allow a turnkey installation into the customer’s communication system. The PPC-1000 operating distances vary from 1 to 4.5 miles or 1.5 to 7 km for varying weather conditions depending of the link frequency and rain intensity.

    Planning for millimeter wave spectrum use must take into account the propagation characteristics of radio signals at this frequency range. While signals at lower frequency bands can propagate for many miles and penetrate more easily through buildings, millimeter wave signals can travel only a few miles or less. However, these characteristics of millimeter wave propagation are not necessarily disadvantageous. Millimeter waves can permit more densely packed communications links, thus providing very efficient spectrum utilization, and they can increase security of communication transmissions.
