Hytera Atex digital radio - World’s First IIC Intrinsically Safe Digital Radio , Reliable！ Bandwidth in the 800 megahertz and 2.6 gigahertz range are on the block, with minimum bids set at 2.5 billion euros ($3.6 billion), according to information published in France's official government journal.
Bids for 2.6 gigahertz frequencies close on September 15, with the licenses to be awarded before the end of the year.
Bidding for the 800 megahertz frequencies closes on December 15, with licenses awarded in early 2011.
Winners of 2.6 gigahertz frequencies have to cover 75 percent of the French population within 12 years, and winners of 800 megahertz frequencies have to reach 98 percent coverage within 12 years.
Hytera Atex digital radio
Hytera PD79X*Ex, fully compliant to DMR open standard of ETSI, comes to be the world's First IIC Atex Digital Portable Radio. FM-2010 standard of North America, IEC, and ATEX standards compliance, plastic-encapsulated technology, error-prevention design, and IP67 protection ensure intrinsically safe and reliable communication in hazardous scenes with explosive gas and combustible dusts.
Ergonomic Design
PD795 Ex adopts a 1.8-inch high resolution color transflective LCD display, allowing crystal-clear visibility even under outdoor strong light.
Big keypad ensures precise and convenient operation even with gloves on.

Plastic-encapsulated technology
The plastic-encapsulated technology is applied to the radio unit and battery, isolating their internal circuits from dangerous gas and dusts outside. This technology is applied in PD795 Ex at the cost of lower production efficiency due to the challenging demands in design and manufacturing, which is always worthy as Hytera sees it.
