1250Mbps Gigabit Ethernet wireless link with fiber optical interface

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.

ELVA-1 Millimeter Wave Division announces new full-duplex 350Mbps Series of 40.5-43.5 GHz and 71-76/81-86 GHz mm-wave bands Radio Links. PPC-350 was specifically designed according to European ECC and US FCC performance requirements.

PPC-350 supports Adaptive Code and Modulation (ACM) in which changers of coding rate and modulation are set in real time, based on the link conditions. This feature enables to increase radio link availability.

Point-to-point 100Mbps Wireless LAN Bridge
(Full-duplex Fast Ethernet Link)

40.5 - 43.5 GHz. According to EN 301 997-1 V1.1.1 (2002-06) European Telecom Standard the "40 GHz" band has been identified and designated within European Union as harmonized frequency band from 40,5 GHZ to 43,5 GHz for Multimedia Wireless Systems (MWS). Multimedia Wireless Systems support information exchange of more than one type, such as text, graphics, voice, sound, image, data and video. The MWS are defined as terrestrial multipoint systems which have their origin in telecommunication and/or broadcasting, and which provide fixed wireless access direct to the end user for multimedia services. All ELVA-1 links for 40GHz band have "CE mark" certification to use in Europe.

Hybrid Point-to-point "100Mbps FE + 8xE1" Link.

Combine data and voice services into one 155Mbps link!

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-100/STM-1 Links

Point-to-multipoint 100Mbps Wireless "City-A" System
(Full-duplex LMDS)

City-A set consists of Switch and Terminals. The Switch is deployed on height dominating building. Terminals are deployed on line-ofsight positions within Switch service area. One terminal can serve a bunch of offices, apartments, houses etc. City-A operates like a Fast Ethernet Router. IP-packets, incoming to Terminal, are forwarding to Switch or, via Switch, to Terminal front-end. IP-packets, incoming to Switch, are forwarding to Terminal of destination.

40.5-43.5 GHz DVB-S Broadcasting "City-1" System

Operation principle

In City-1 DVB-S standard is used, as in satellite TV/IP broadcasting. The only difference is a frequency range. For full compatibility to satellite equipment, City-1 transmitter and receiver have L-band interface (IF = 950 to 2150 MHz). This allows using any satellite equipment both at base station and receiver side.
