Advantages of TETRA in Oil & Gas Industry

-1) To expand the existent VHF system (Smartrunk) Not possible, max 15 channels

-2) To convert the existent system to an analogic trunking (MPT 1327- 160 Mhz)   Not possible, max 15 channels (by local regulation)

-3) To install a new trunking system at a new band (MPT-1327) Possible but expensive, many batteries needed, more space required, many sites (combiners & duplexers, reduce cell sizes => Trunking

Effect less effective => More Channels => More combiners & duplexers , smaller cell sizes …. And so on.)

-4) To use cell phones from an operator   Not possible, Only 10% with local operator coverage, and without channel availability ensured at emergencies

-5) To install a cell network    Expensive but many sites required (area 19 times larger than Buenos Aires city) but not all requierement could be satisfied).

-6) To install a digital trunking TETRA  All requirements satisfied
