The Millimeter Wave Division of ELVA-1 has announced another installation of its specially modified PPC-1000 Gb Ethernet mm-wave link for Czech ISP JHComp. Both residential and business customers will benefit from Internet and voice service improvements...

Czech networking and communications technology distributor Atlantis Datacom has installed a Czech Republic version of ELVA-1's Gigabit Ethernet radio link, in this case for ISP JHComp and centred around Jindrichuv Hradec. This new version of ELVA-1's PPC-1000 model is produced specifically for operation in the Czech Republic. Authorised frequency bands are 74-76 GHz and 84-86 GHz, whereas a standard PPC-1000 operates in the 71-76 and 81-86 GHz frequency bands.

Among the characteristics of the Czech radio link are the PPC-1000 antenna radomes which have a special covering which prevents snow from sticking to them. One helpful aspect of the 74-76 and 84-86 GHz radio frequencies is that they can be used in the Czech Republic for operating wireless links without individual authorisation.

A Concept of General Authorisation for radio frequency use and for the operation of equipment in these bands was issued by the Czech Republic Ministry of Telecommunication this April. The intention is for ISPs to use these bands and to stimulate innovations in equipment developed for them. An advantage of the 74-76 and 84-86 GHz frequency bands is the freedom from interference from other nearby radio links, even those operating in the same bands. Multipath reflections are non-existent at these frequencies, and the narrow beam width of the Cassegrain Antenna allows many radio links to work simultaneously in the same area.

One condition of the Czech Concept is that the radio systems (stations) may operate only with minimal antenna gain of 43 dBi and antenna input power of 30 dBm maximum. ELVA-1 PPC-1000 Gigabit Radio Links satisfy these requirements. ELVA's PPC-1000 digital radio links "provide full duplex wireless Ethernet data pipelines that are equivalent in capacity to 512 E1 lines or 2 ?5 lines in PDH. The operating distance of these Radio Links varies from 1.0 to 7.5 miles, depending on the LOS path and rain intensity. Their conformity to ECC requirements allows all European Countries to use PPC-1000 Gigabit radio links for wireless connections to remote regions."

* Founded in 1993, ELVA-1 Millimeter Wave Division is a private manufacturer of millimeter wave integrated components, subsystems and test equipment. In 2000, ELVA-1 began aggressively expanding its product range into millimeter wave telecommunications products, such as 42GHz, 70/80 GHz and 94GHz transmitters and receivers, high gain antennas and other advanced wireless communications products.

** Atlantis Datacom is a networking and communications technology distributor, representing more than thirty worldwide manufacturers in the Czech Republic. It was founded in 1996 as a sister company of Atlantis Telecom. Both companies act today as one, sharing resources, facilities and know-how. Their gross income for 2007 was almost US$13 million.
