Who is Avari Wireless?
®
Avari® Wireless designs and manufactures public safety (PS) Digital Distributed Antenna Systems (DAS) for Emergency Responder Communications Enhancement Systems (ERCES).
​
Being able to communicate with wireless public safety two-way radio systems indoors is crucial for first responders to execute time-sensitive and mission-critical tasks to protect the public. Unfortunately, this is not always possible due to building materials that may weaken or block out wireless signals. An ERCES is often installed to provide these necessary means of communication.
​
The Avari VL™ Series solution is perfectly suited for medium to large complex mission-critical in-building communication deployments. It can overcome common and difficult challenges that are often present in these expansive deployments. The system supports all public safety LMR frequency bands, can work with technology inside, or outside of the building, and is future-proof.
​
Avari is steadfast in its mission to create the most reliable and advanced ERCES system to protect our first responders and the public alike.

Avari VL™ Clock
Built-in 10MHz clock reference signal that is used to feed the same clock reference signal to two separate VL-DMU™ / VL-AMU™ units over fiber in a redundant head-end configuration. In order for automatic fail-over protection to work, the two hosts at the headend locations must be synchronized with the same clock reference.
