Access Point Placement

Observe the following recommended guidelines to help ensure a successful network deployment:
• Identify all pieces of the mounting bracket and mounting extension arm hardware and ancillary hardware (see
Hardware on page 8 ).
• Mount the device with the black gore vent down.
• Mounting height for network devices should not exceed 30 to 35 feet. Mounting height should vary to accommodate the
topography of the deployment area, foliage, and other obstructions.
• Devices can be deployed using any of the recommended outdoor deployment procedures.
• Line of sight (LoS) guidelines should be given special consideration whenever devices will not be installed in a straight line,
such as deploying devices on alternating sides of a roadway.

Grounding Requirements

To avoid damage to the equipment, become familiar with Motorola Solutions Policy R56 before installing AP 7161 units. Refer
to Standards and Guidelines For Communication Sites, Version B. Both the hardcopy manual (Part Number 68P81089E50-B)
and the CD version (Part Number 9880384V83) can be ordered from Motorola Solutions.
Section 7.6.4 Broadband - Wireless Access Point Network from the Standards and Guidelines For Communication
Sites applies directly to AP 7161 deployments: SPD (Surge Protection Device) considerations for broadband shall include the
use of SPDs to protect pole-mounted access points and ground-based cabinet architecture. It is important to install proper SPD
applications on both ends of Ethernet, Power-Over Ethernet (POE), Giga-Ethernet (GigE) and AC cable runs. SPDs shall be
located within the node or cabinet, or as close to the entrance as possible, and properly installed into load centers, control
panels and utility power cabinets. While RF protection is a consideration, it shall only be required when antennas are connected
to the node with coaxial cables greater than 610 mm (2 ft.) in length.
Lightning protection should be used on all shielded CAT5E Ethernet connections.
An outdoor rated Lightning Protection Unit (LPU) kit such as the Motorola Solutions PTP WB2978AA or the HyperLink
AL-CAT6HPJW Lightning Protector should be used.
To properly attach the grounding cable to the access point, refer to
NOTE

Ethernet and Lightning Protection

When installing an AP 7161, lightning protection should be used on all Shielded CAT5E Ethernet connections. An outdoor rated
Lightning Protection Unit (LPU) kit such as the Motorola Solutions PTP WB2907AA or the HyperLink AL-CAT6HPJW Lightning
Protector should be used. For more information on Motorola Solutions PTP Lightning Protection Unit, refer to the PTP-LPU
Technical Specifications.
For the best possible protection, each radio requires an LPU be installed adjacent to the radio. If there is a LAN connection to an
indoor network, a second LPU is required at the cable entry point to the building.
Lightning damage is not covered under the conditions of a standard Motorola Solutions product
warranty. When installed correctly, LPUs provide the best protection from the harmful effects of
lightning. Observe all regional and national codes that apply for lightning protection.
