   PPC-100FE/8E1 Wireless LAN Bridge with Optical Multiplexers
(1 port 100Mbit Fast Ethernet + 8x ports E1)

100Mbps + 8E1 Point-to-point wireless mm-wave link with total throughput 155Mbit and fiber optics interface

100Mbit FE + 8E1 mm-wave radio with optical mux


PPC-100FE/8E1 is wireless point-to-point link that provides mm-wave radio connectivity for  the following mm-wave bands: 40.5 - 43.5 GHz, 57.0 - 65.0 GHz, 71-76 GHz and 81-86 GHz, and 92-95 GHz.  The main channel is full-duplex 100Mbit Fast Ethernet plus 8xE1 additional channels transmitting simultaneously. The total link throughput is 155Mbit which is coming to uplink port of optical mux "100Mbps + 8E1". The link kit shipment includes two optical multiplexers "100Mbps + 8E1" among two mm-wave radios (one for each side of the link).

  Applications of Point-to-point PPC-100FE/8E1 Links

For PPC-100FE/8E1 model the primary application is interconnection between base station sites in cellular networks (GSM / GPRS / UMTS). PPC-100FE/8E1 provides an ideal intranet-intranet and intranet-public network connection solution as wells as any LAN / WAN connection where there is a requirement to combine data and voice services in one link.

Other general purpose applications are the following:

  • Wireless full duplex connection link for remote LAN segments at corporate and university campuses
  • FSO (atmospheric laser) and fiber optics channel back-up
  • Multipurpose Fixed Wireless communications for any field use

PPC-100FE/8E1 links are featured with remote management and parameter monitoring capabilities. To communicate with the link for SNMP and parameter control, there is a special twisted pair cable patch which has to be connected to any RJ-45 socket within LAN, deployed in the building. This allows remote SNMP management and remote parameter monitoring of
PPC-100/STM-1 links from a central location.

These "100Mbps + 8E1" point-to-point millimeter wave radio systems are available with a choice of three different sizes of compact parabolic Cassegrain antenna - 30 cm, 45 cm, and 60 cm. Depending of the link frequency, these antennas deliver operating distances from about 1.5 mile to 9.5 miles (2.5 km to 15 km) for fair weather condition.

Note. The only weather condition that could affect mm-wave link performance is rain - because the size of rain drops is about the same one as for link wavelength. This brings an interferential dispersion. Luckily, a rain cannot almost break the link, only could cause some kind of operation disturbance. To be sure in "five 9" reliability all the time, it is advised to get in consideration the actual local climatology factor. Rain strength is measured in mm/hour and these data are available in your local meteorological service, especially at nearest airport.

For easy adjusting of radios to a true line of sight, PPC-100FE/8E1 "100Mbps + 8E1" link is shipped with aux electronic adjusting unit. This unit has own display to see changes in primary parameters of the link gain during adjustment process.

Special PPC software application is used to detect, monitor, and configure ElvaLink terminals connected within the same network. The PPC Main window displays status readings and parameter values for the active PPC-100FE/8E1 terminal.
