Public Safety Band Selection
The supported public safety frequency bands are:
VHF or 150 MHz (150-174 MHz, bandwidth: 24 MHz, 2 W)
UHF or 450 MHz (450-512 MHz, bandwidth: 62 MHz, 2 W)
700 MHz (bandwidth: 17 MHz, 2 W)
800 MHz (bandwidth: 18 MHz, 2 W)
900 MHz (bandwidth: 6 MHz, 2 W)
For single channel frequency bands, airHost PS and remote units support up to 5 W output
power, type 2 chassis only. Up to four public safety bands can be deployed. Band selection
is pre-configured by Dali Wireless.

hdHost PS Base Station Host Unit
The hdHost PS is a quad-band host unit that connects directly to base stations or bi-
directional amplifiers (BDAs) over an analog RF interface to process up to four public safety
RF bands simultaneously.
On the downlink (DL) path the hdHost PS translates analog RF content into a digital data
stream, and then transports it to remote units over one to eight optical links, each operating
at a data rate of 10 Gbps. Because all radio signals are processed and combined in the
digital domain, no passive intermodulation (PIM) is introduced. The aggregated content is
then sent over optical fiber to the remotes.
On the uplink (UL) path the hdHost PS performs the reverse functions. It delivers digitally
transported uplink signals to corresponding base stations as analog RF signals and IP data
from remotely connected IP devices to the Internet or other devices in the cloud.
The hdHost PS also supports 1 Gbps Ethernet backhaul for additional IP devices such as
security cameras and Wi-Fi access points located close to remote units.
