Carrier Access FREEway
License-free 5.3/5.8 GHz Point-to-point DS3/Ethernet
Microwave Radio

Key Features:
• License-free operation in the 5.8 GHz ISM band or 5.3 GHz UNII band
• DS3/Ethernet or Ethernet-only configuration
• Advanced design is extremely resistant to interference
- Remote, software controlled dual sub-band frequency peration
- Very narrow RF channel bandwidth (16 MHz)
• Environmentally hardened single unit design for indoor or outdoor installation
• Integrated antenna or external antenna options
• SNMP, Telnet, and web browser management
• Integrated, remote controlled path diagnostics and troubleshooting utilities

Reduce operating capital expenses with cost-effective, license-free radios:
FREEway is a fully hardened, self-contained point-to-point microwave radio. The architecture is
designed for either indoor or outdoor use, and is a carrier-class design supporting 99.999%
availability. FREEway's TDM and packet based feature set combined with a robust resistance to
RF interference make it an ideal solution for cellular/PCS.

Two configurations are available, each for operation in either the 5.3GHz UNII or 5.8GHz ISM
bands. A dual DS3/Ethernet configuration supports both a full duplex 45 Mbps DS3 channel
and a 1 Mbps Ethernet wayside channel. An Ethernet-only configuration supports 45 Mbps of
full duplex transmission.

Unlike competitive solutions that require 50 Mhz of spectrum and only support a single
sub-band for each radio path, FREEway utilizes very narrow 16 MHz RF channel bandwidth.
When combined with Frequency Division Duplex (FDD) operation and very low latency, these
advanced technical design attributes make FREEway extremely resistant to RF interference.
Installations in even harsh, dense urban environments are feasible.

FREEway has two antenna options: an integral space saving flat panel antenna option for
applications up to four miles, or an external antenna connection for applications up to 40 miles.
Maintaining Carrier Access’ product design focus on advanced remote control and diagnostics,
FREEway supports SNMP, Telnet, or web browser based management connectivity. Remote
configuration and diagnostics is supported including built-in utilities for bit error rate testing
(BERT) and loopbacks for both network and RF interfaces.

With carrier-class design and performance, Carrier Access’ FREEway family of radios is the ideal
high-capacity solution for mobile wireless service providers, wireless ISPs, carriers, and private
enterprises that are looking to upgrade and expand their networks.

What makes FREEway different?
• License free operation eliminates cost and complexity of alternative wireline or licensed microwave solutions
• Flexible design supports both TDM and packet based networking
• Advanced RF transmission design makes deployment feasible in dense urban environments
• Extremely price competitive compared to other industry solutions
