Digital radio by Icom: the company’s IDAS range, pictured here, is upgradable to ETSI dPMR through a change of firmware


102 658 Tier 2 Mode 3 dPMR standards, the new product family will be suitable for high-quality trunked and networked radio systems from a single site up to 16 sites. Further enhancements planned for next year will extend it to a theoretical maximum of 1000 sites or 500000 subscribers, with telephone interconnect and other features. Fylde and Icom explain that


their system will also be unique in offering an immediate migration path from MPT to dPMR without the requirement for any MPT operation in the IDAS terminals. Fylde’s fourth-generation Multi-


Lingo trunking controller will be able to encode/decode analogue MPT signals to and from digital dPMR signals and vice versa. Tis will avoid the need for parallel infrastructures to allow MPT and dPMR to work together.


Digital tiers


ETSI dPMR is a digital radio protocol designed to provide high functionality at low cost and with low complexity. Its narrowband (6·25 kHz) FDMA technology offers a range of functional levels.


Tier 1, also known as dPMR446, is for licence-free operation. Tier 2 includes licensed peer-to-peer op- eration (Mode 1), base station and repeater use (Mode 2) and multi- site, wide-area networked systems (Mode 3). www.dpmr-mou.org
