Caveat
Spread spectrum point-to-poi n t radio r e lay l inks l ike A uro ra’s are allowed by various regulatory agen cies t o operate unlicensed on a “noninterference basis”. Because of the unlicensed natu re, the Aurora radios r equire neither frequency licensing nor prior coordination in most regions. Good engineering judgment needs to be exercised by the operator and professional installer to avoid selecting paths or locations near equipment or facilities that could generate interfering signals. Such equipment might include microwave ovens and o ther high-power ISM devices. Additionally, precaution should be taken when links are deployed in a region where a large number of other 5.8-GHz, point-to-point or point-to-multipoint links are installed.
The Aurora installation software with its adjustable power feature is for professional installer use only, as mandated by the Federal Communications Commission (FCC, Part 15) and the European Telecommunications Standard Institute (ETS 300-328). The customer version is provided with the adjustable power feature disengaged.
Harris Corporation does not as sume any liab ility or damage a rising out of t he applicati on or misus e of this Aurora radio product and its sof twa re.
Warranty
Any warranties or conditions made herein by Harris are exclusive, made in lieu of all other w arranties or conditions, express or implied (except to title) including, but not limited to, any implied warranty or condition of merchantability, any implied warranty or condition of fitness for a particular purpose, or any warranty or condition arising out of performance or custom or usage of trade. Customer acknowledges any circumstances causing any such exclusive or limited remedy to fail of its essential purpose shall not affect any Harris warranty.
Aurora 5800 contains no user-serviceable or replaceable parts.
Limitation of Damages
Harris’ total and maximum liability under this agreement, or in connection with the subject matter of this agreement, or any transaction related to this agreement, shall be limited to one-half (1/2) of the aggregate amount paid to Harris, regardless of the basis for such liability. The customer acknowledges and agrees that this section shall be enforceable in the event of any claim made in connection with this agreement, including, but not limited to, any claim for failure of delivery. In no event shall Harris be liable for any punitive, special, incidental, or consequential damages, including, but not limited to, lost profits, opportunities, or savings, or for any loss of use of, or loss of data or information of any kind, however caused, or for any full or partial loss of performance of any product, even if Harris has been advised of the possibility of such damages.

Aurora 5800 Overview

The Aurora 5800 is a spread-spectrum, digital micro wave radio that operates in the 5.725 to 5.85 GHz Industrial, Scientific, and Medical (ISM) frequency band. It provides wireless interconnection for private wireless access, Internet service access, LAN/W AN, cellular , and PCS/PCN systems.
The Aurora radio offers deployment of standard T1 (DSX-1) or E1 (CEPT-
1) and 2 24 km (15 miles) (with 28-dBi, flat-panel antenna). It provides reliable, full­duplex, digital communication between two sites with line-of-sight clearance.
This radio offers thre e frequency pairs at 1 × E1 (2.048 Mbit/s) and 1 × T1 (1.544 Mbit/s) or two frequency pairs at 2
×
T1 or 2 × E1 wireless service with a typical distance from 1 to over
×
E1/T1 in the 5.8 GHz ba nd.
Additionally, the Aurora 5800 features a voice/data orderwire and a network management syst ems channel. The network management systems channel provides a SCAN channel to integrate into Harris’ FarScan element manager or an SNMP-based interface to integrate into an SNMP mana ger.
There is a built-in Craft Interface Tool (CIT) user interface for local and remote radio mo nitoring and control.
The Aurora uses Direct Sequence Spread Spectrum (DSSS) processing that reduces the transmitted power density and the potential for interference into neighboring comm unication systems.

The Aurora can be used in point-to-point and repeater configurations. In the repeater configuration, the radi os serv e as lin ks betw een sites that are beyond each other’s range or whose paths are obstructed.
This radio supports either indoor or outdoor environment. This is a compact lightweight radio that requir es only one rack-mounting space for a rack or table-top placement in an indoor environment. This radio requires one open rack-mounting space (1 RMS) above and on e below. For placement outdoors this radio can be installed in an outdoor cabinet.
Aurora 5800 links operate license-exempt on a “no-interference, nonprotection” basis in the U.S.A. and in many c ountries and regions worldwide. In Canada, however, Aurora 5800 links share the existing 5.725 to 5.85 GHz “Super 2” point-to-point band and therefore may be subject to interference coordination and Industry Canada licensing procedures.
