Some of the first commercial DMR Tier III trunking radio networks in the world can be found in the Central American republic of Guatemala, where a variety of radio systems for public and private users are operated by a local company, Corporacion Radio Electronca S.A (Crelosa), the largest trunking radio network operator in Guatemala. Today Crelosa’s operations embrace 19 DMR radio sites, 6 shared subscriber networks and 14 private systems. Among their customers and users are government bodies, police, firefighters, and Transurbano, Guatemala City’s integrated metropolitan transit operator.

The Challenge

  • hytera-image

    Currently, Crelosa ran a wide range of analog, LTR and digital mobile services for business and government. With the growing demands in communication, Crelosa gradually realized the inferiority of analog in communication and data services. End users often complained its network for unclear audio quality and existing blind area in communication.

    While some taxi users kept a wait-and-see attitude because it couldn’t provide large capacity of GPS service. For public safety users, they chose giving up because of the high rent brought by P25 equipments. So Crelosa decided to replace the existing network in stages with Hytera DMR Trunking Pro.

    As part of the modernization program, the Bureau wanted to upgrade the communication and incident recording solutions available to customs staff. It wanted to implement a body worn camera (BWC) system to provide daily recordings and real time viewing capabilities.

    The BWC solution was needed to capture video evidence, so the footage could be used to review incidents. BOC also wanted to deploy BWCs at ports throughout the Philippine archipelago to enhance its monitoring activities.

The Solution

Hytera DMR Trunking Pro based on Hytera infrastructure was adopted for Crelosa in 2012. At the first stage, four DMR trunking base stations were installed to cover the centre Guatemala. Compared with analog network, newly-built DMR trunking system provides double user capacity and traffic capacity, which can stably support more than 4000 end users.
