Installation Overview
The installation process involves major four steps:
• Wireless link planning
• Installing the hub
• Installing and aligning the CPE(s)
• Installing the customer cable modem
Wireless link planning
Wireless link planning is essential to the success of WPE installation and is highly
recommended before attempting to install the equipment. Refer to Arcwave’s Wireless
Plant Extension Application and Deployment Training presentation and Wireless Link
Planning Tool located on Arcwave’s support extranet or contact Arcwave customer
support for guidance on how to complete this step.
An acceptable wireless link is one within the working range of Hub and with line of sight
clearance to the customer sites.
Line of sight is defined as a path between the hub and CPE that is free of obstructions in
the Fresnel zone. Obstructions can be trees, buildings, street signs, etc. An accepted rule
of thumb is that LOS conditions exist when there are no physical obstructions within 60%
of the Fresnel zone (obstruction free zone). The Fresnel Zone clearance is determined by
the distance between the Hub and CPE as shown in the following illustration and table.
Range 500 ft 1000 ft ½ mile 1 mile 2 miles
Clearance Radius 3 ft 4 ft 6 ft 9 ft 12 ft
