Solar 25

Simoco Solar 25 is the latest ‘Dalman Inside’ simulcast product to be developed by our specialist simulcast engineers at Dalman Labs. Leveraging over 25 years of dedicated simulcast engineering, research and development, Solar 25 now extends the benefits of Dalman’s revolutionary simulcast over IP to the P25 environment.

Solar 25 Economics

Simulcast technology synchronises duplicated channels in a wide area network to avoid interference between adjacent radio sites. Solar 25 Digital VoIP signals are better defined and more consistent than their analogue counterparts, enabling the synchronisation task to be ‘processor controlled’.

This advantage revolutionises the economics of simulcast deployment and support; enabling automatic set up and remote management to replace specialist knowledge, costly test equipment and reduced on-site maintenance. Simoco Solar technologies extend the benefits of simulcast by removing traditional barriers of cost and technology complexity for customers.

Traffic Manager Capacity: A single Solar 2 Traffic Manager can accommodate a maximum number of 32 Base Stations with a maximum of 16 console interface connections by default. With the additional channel option, the user can select Stations to form independent channel groups (to a maximum of 16) and allocated the number of console connections to each channel as appropriate.
Voting: Receiver selection or receiver voting is conducted in the digital domain by the TM using signal information passed down from the station interface. Due to the noise free nature of the digital link, no further signal evaluation is necessary at the TM which means that the IP data packets contain both the received audio and the signal level/ quality information together so voter risetime is the absolute minimum. Solar 25 can accommodate either a ramping voltage or a set of tones as a source of RSSI signal.
Synchronisation: Synchronisation operates within 2 micro seconds compared with other base stations for both talk in and talk out directions. Switching the “vote” mid-transaction will only cause a disturbance of the input within the specified figure. Monitoring and control system configuration and status is available via a PC running the engineering terminal software supplied, and is connected either via USB or over the IP network to the TM. Standards based management is also available via the SNMP monitoring and control option to the TM allowing connection and sending of traps to a higher level management system. A closed contact summary alarm output is also provided on the central NI for connection to external alarm systems.
