What are Millimeter Wave Bands for ELVA-1 Point-to-point Links?

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.

Point-to-point 100Mbit wireless mm-wave link

PPC-100 LAN Bridge series are wireless building-to-building links that provide mm-wave radio performance for wireless Ethernet LAN-to-LAN connectivity. The links are available at 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.

From LAN administrator view, the PPC-100 link is a transparent, ISO/OSI physical layer, wireless bridge that can connect two or more Ethernet LANs.

Unlike its software-based competitors, PPC-100 bridge is really fully transparent, software-free unit, and other LAN devices as host computers, routers, and so on cannot detect its presence. In other words, PPC-100 radio works much more like ISO/OSI physical layer repeater than a traditional MAC Layer Bridge.

The PPC-100 link may pass all Ethernet like protocols including IP, IPX, AppleTalk, etc. True symmetric full duplex throughput is at standard Ethernet 100 Mbps at each direction. For customers from USA/Canada and a number of countries where 60GHz band  is a FCC license free band we advise to pay a special attention to stations with VXX index that are built especially for 60GHz band. This allows you to benefit from PPC-10/100 functionality but have no hassle with bandwidth licensing. A custom band up to 140GHz could also be considered.
