Today Crelosa’s operations embrace 19 DMR radio sites, 6 shared subscriber networks and 14 private systems.

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.

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.
