ATLAS conventional systems solutions have a dedicated repeater channel for system user groups. Typically they are deployed in regions covering large geographic areas and/or have moderate quantities of users. Often these system user groups are organized based upon responsibility such as Fire, Police, EMS, Public Works, and Mutual Aid, and in many cases each of these groups have a corresponding dedicated repeater channel. The ATLAS conventional system provides mixed mode analog/P25 operation which allows a graceful, cost- effective radio migration strategy. Conversion to a P25 trunked system is made simple primarily via a software upgrade to the repeater channels.
ATLAS trunked systems solutions have a shared pool of repeater channels for use among system user talkgroups. Typically, they are deployed in regions covering moderate geographic areas and/or have large quantities of users. Often these system talkgroups are organized on a functional basis such as Fire, Police, EMS, Public Works, and Mutual Aid. In trunked systems, the repeater channels at each site are divided into a "control channel" and multiple "voice channels." The "control channel" registers the radio into the system and dynamically coordinates radio talkgroup PTT (push-to talk) with any available "voice channel." The shared pool of repeater channels facilitates more talk groups and significantly more users than a dedicated repeater channel in a conventional system. The ATLAS trunked system is based upon industry-standard P25 operation which promotes interoperability and maximizes grant funding opportunities.
ATLAS hybrid systems solutions are an industry first unique implementation that combines conventional and trunked repeater channels into a single system. Typically, they are deployed in applications where both large and small quantities of users are found in separate geographic areas. With this system, users can be organized functionally such as Fire, Police, EMS, and Public Works, for either the conventional or trunked part of the system depending on need. The ATLAS hybrid system provides significant cost savings by applying trunked sites only where needed. With a simple method for converting repeater channels from conventional to trunked, initial investment is maximized and capacity can be expanded as required. Additionally, call routing between conventional and trunked system repeater channels is patch free, meaning that dispatch console assistance is not required to connect these disparate system types.
ATLAS simulcast systems solutions are configured for conventional or trunked operation. Typically they are deployed in regions covering moderate geographic areas, have limited frequencies available, and often require improved in-building radio coverage. Similar to other architecture options, these systems are organized on a functional basis such as Fire, Police, EMS, and Public Works. Simulcast systems have a single master site and multiple remote sites. The master site "synchronizes" the system timing so that calls are transmitted simultaneously at all sites for a given repeater channel, which reduces the quantity of frequencies needed for the system and simplifies frequency coordination. The ATLAS simulcast system supports analog conventional, P25 conventional and P25 trunked operation. Auto discovery, tuning, and network delay compensation result in quicker system turn-up and reduced maintenance activities. Conversion from a P25 conventional simulcast system to a P25 trunked simulcast system is made simple primarily via a software upgrade to the repeater channels.
