The Challenge
-
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.
