A Czech Republic version of ELVA-1's Gigabit Ethernet Radio Link hs been installed by ATLANTIS Datacom, Czech networking and communications technology distributor, for Internet Service Provider JHComp in Jindrichuv Hradec, Czech Republic. This special version of ELVA-1 model PPC-1000 is produced specifically for operation in the Czech Republic, where the authorized frequency bands are 74-76 and 84-86 GHz, while a standard PPC-1000 intended for world use operates in the 71-76 and 81-86 GHz frequency bands.

Without individual authorization, 74-76 and 84-86 GHz radio frequencies can be used in the Czech Republic for operating wireless links. On April 21, 2008, a Concept of General Authorization for radio frequency use and for the operation of equipment for fixed radio systems in the 74-76 GHz and 84-86 GHz bands was issued by the Czech Republic Ministry of Telecommunication. This Concept stimulates innovations in equipment developed and authorizes Internet Service Providers to use these bands.

The freedom from interference from other nearby radio links, even those operating in the same bands, is an advantage of the 74-76 and 84-86 GHz frequency bands. The narrow beam width of the Cassegrain Antenna allows many radio links to work simultaneously in the same area, while Multipath reflections are non-existent at these frequencies. The fact that the radio systems (stations) may operate only with minimal antenna gain of 43 dBi and antenna input power of 30 dBm maximum, is One condition of the Czech Concept. 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 Е5 lines in PDH. Depending on the LOS path and rain intensity, the operating distance of these Radio Links varies from 1.0 to 7.5 miles.
