1 Introduction
Gigalink Product Family
The Terabeam®Gigalinkmillimeter wave radio system represents an entirely new
approach to broadband communications. Based on our extensive experience with millimeter
wave systems for military and research applications, we now apply these techniques to a
commercially priced version with our ultra-broadband family of Gigalink radio products.
The Gigalink broadband radio system operatesin the FCC Part 15.255 unlicensed band
covering a frequency range of 57.05 –64.0 GHz. Due to the unlicensed status of this band,
FCC license or special authorization is not required to operate our Gigalink systems. In
addition, the high atmospheric absorption of RF energy at this frequency virtually eliminates
any chance of interference from competing systems or unauthorized interception of the
broadcast signal.
The installation procedures detailed within this guide are similar to those used to install any
wireless system. In fact, certain attributes of the 57.05 –64.0 GHz band actually simplify
deployment. The key to any successful installation project is proper planning and design. The
Gigalink radio product has been designed for ease of installation and trouble-free operation.
We recommend that you read and fully understand this guide prior to initiating the actual
installation work.
As stated above, the key to successful installation is proper system planning and execution.
As with most wireless systems, the Gigalink radio system requires un-obstructed Line of
Sight (LOS) to operate reliably. Because of the extremely high data bandwidth provided by
the Gigalink system (1.25Gbps) it is likely that our radio systems will be utilized as a critical
or primary network connection. This absolute reliance on our systems for connectivity
demands a focused attention to detail in order to assure un-interrupted operation.
Reliability
All Gigalink products are designed to provide a minimum statistical path availability of
99.99% (BER <1 x 10 –9) when operated within the recommended range envelope.
Exceeding the specific model range restrictions will result in unreliable operation particularly
during adverse weather.
Statistical availabilities in excess of 99.99% may be achieved by choosing the next longer
range system for a given path or by co-locating two Gigalink systems. Traditional circuit
redundancy methods utilizing collapsible ring architectures or media diversity may also
increase statistical availability.
