Cobham Wireless will start shipping a combined LTE and TETRA version of its idDAS system for public safety in Q4 of this year.
The public safety model will cover TETRA bands and is designed to increase the coverage range of infrastructure to reduce costs for the operator. Features will be identical to the cellular version, which was launched last year and is still used in LTE public safety infrastructure but without support for TETRA frequencies.
A new addition for public safety idDAS is the ability to improve performance through TETRA uplink sensitivity. This is managed through a voting approach and allows a remote unit with the best receive conditions to pick up signal. This improves the uplink signal to noise ratio and send and receive signal.
idDAS is a robust in-building coverage solution that allows operators and infrastructure providers to move capacity around and reduce both CAPEX and OPEX. It provides a coverage solution that is suitably sized for the application and can be changed depending on demand.
It removes the need to hardwire capacity to provision for peak demand and stops the building of a network where capacity is unused for a large proportion of the time.
idDAS also features:
- Patented noise management techniques
- Flexible plug-and-play approach
- Inherent MIMO capability
- Native and direct CPRI routing
- Supports C-RAN architecture
“If you have a chain of remote units, idDAS can deactivate those that don’t see traffic,” said Ingo Flomer, director of product management at Cobham Wireless. “This means the overall signal to noise ratio in that sector is much better and you can catch more throughput and wider range signals.
"This is another existing feature of idDAS that we’ve applied for cellular already, which is great, it means the reduction of CAPEX and OPEX and an increase in performance.”
