Overview
This document provides technical details on enabling emergency communications indoors using Avari Wireless solutions. It highlights the capabilities and features of their Public Safety Distributed Antenna System (PS DAS) designed to enhance signal reach and fidelity for first responders.

Specifications
- Maximum optical path loss of 27dBo for greater reach without signal degradation.
- Supports VHF, UHF, 700, 800, and 900 MHz bands, with easy future expansion.
- Offers 5W composite output power per band and supports up to 3 RF bands in one unit.
- Available in 32 and 64 channel operations.

Supported Bands
- 150 MHz: UL/DL Range 138-174 MHz
- 450 MHz: UL/DL Range 380-450 MHz / 450-512 MHz
- 700 MHz: UL Range 788-805 MHz, DL Range 758-775 MHz
- 800 MHz: UL Range 806-824 MHz, DL Range 851-869 MHz
- 900 MHz: UL Range 896-902 MHz, DL Range 935-941 MHz

Integrated Headend Platform
- Replaces multiple off-the-air Class A BDAs with a single multiband headend unit.
- Smaller footprint, lower cost, and easier integration with battery backup and alarm panels.

Scalable Multiband Operation
- Supports star, daisy-chain, hybrid, and ring topologies to maximize fiber resources.
- Allows RF content aggregation from different radio systems and geographic origins.

Automatic Optical Delay Compensation
- Measures signal arrival time to each remote unit and balances it to synchronize the antenna system network.
- Utilizes a single fiber strand for both uplink and downlink with WDM operation.

IP Backhaul
- Provides 1 Gb/s Ethernet backhaul for IP appliances like WiFi access points and security cameras.

Cost-Effective Redundancy Operation
- Features flexible redundancy operation and programming using an advanced rules engine.
- Includes automatic failover and intelligent control for reliable operation.

Automatic Switchover Operation
- Describes the normal and temporary primary operation modes for maintaining communication during failures.
