FCC ruling opens U.S. market for TETRA LMR: PowerTrunk is already approved to sell TETRA in the U.S.

PowerTrunk TETRA equipment has already been approved for sale in the U.S. and Canada by the FCC and Industry Canada.
"This TETRA waiver is one of the most important recent FCC decisions for the U.S. market. This ruling fully opens the door to a technology which has been well proven to be successful throughout the rest of the world - and which the U.S. market can now finally benefit from," stated Jose Martin, Chief Operating Officer of PowerTrunk. "PowerTrunk is leading the entry of TETRA technology into North America. We are the first company to install a TETRA pilot network in Canada in BC Hydro, and the first in the United States in NJ TRANSIT."
PowerTrunk has been instrumental in the introduction of TETRA into the United States as it was the first company to obtain a type acceptance certificate for a TETRA base station radio/repeater, followed by type acceptance certificates for its TETRA subscriber unit and its TETRA mobile unit. As a result, today PowerTrunk is the only company authorized to sell the entire TETRA product range of base stations, subscribers and mobiles in North America. These type approvals were obtained by using a spectrum-compression technique based in a modification of the roll-off parameter of the TETRA modulation that eliminated interference with existing systems. This roll-off compression modification results in an insignificant power reduction that has inconsequential impact on operational performance.
The FCC partial waiver allows TETRA equipment to be deployed in the United States without the power restrictions previously required to obtain equipment type approval. The FCC has endorsed PowerTrunk's existing type acceptance certificates which have been automatically upgraded to feature TETRA up to its full extent of RF power in 450-470 MHz and 817-824/862-869 MHz. For bands not included in this FCC waiver, PowerTrunk will commercialize its TETRA range of products with the existing roll-off compression until a future rulemaking authorizes usage of maximum power.
PowerTrunk's product range covers 409-430 MHz, 450-470 MHz and 806-870 MHz. All PowerTrunk FCC-approved TETRA equipment can be modified by software upgrade, without any hardware change, to operate with a higher transmitter output power. "PowerTrunk greatly appreciates the enormous efforts of the TETRA Association to bring about this decision by the FCC," added Jose Martin. "We would also like to thank RCC Consultants for their expert advice about the U.S. market that helped advance the waiver."
