Planning your WLAN Network The wireless network is much different with a wired network. The Installation of a wireless network requires some additional planning. This planning includes RF Link Engineering like RF Path planning, site selection, and back-bone network preparation.
Site Survey & Planning Definition A site survey is a task-by-task process by which the surveyor discovers the RF behavior, coverage, interference, and determines proper hardware placement in a facility. The site survey’s primary objective is to ensure that mobile workers and the wireless LAN’s clients experience continuously strong RF signal as they move around the facility.
Wireless Network Planning Procedure 1 (Location) 1. Select and identify enough location candidates to determine freely as the install point regardless of some design change to some extent. 2. The most crucial parameter is the range at which APU and CSU or other Wi-Fi Client are required to operate. The range can be determined by a conventional formula which consider a various kinds of environmental and radio equipments. 3.
29 Installation General This section provides a complete set of procedures for the installation of WLAN 6220 equipment. It includes cable assembling information as well as required connection information for the WLAN 6220 units, mounting and powering instructions. It is intended for use by trained installers familiar with CATV or Cable Modem and Wireless installations.
30 CSU(Corporate Service Unit) Required Tools and Materials Before you install the WLAN Cable Access Point 6220, ensure that the followings are prepared for installation work. APU WLAN Cable Access Point 6220 APU package does not contain an antenna and universal antenna bracket kit. For list of antennas and accessories, see the WLAN Cable AP 6220 manual or contact your local Nortel networks representative.

PC or workstation with a Web browser for configuration WLAN Cable Access Point 6220 NTPM99CA Rel 1.
32 APU Installation & Configuration Mounting and Installation Concept Figure 3-1 APU Installation Concept on CATV Network Facility By default, APU is strand mountable. Each unit is shipped with a strand clamp module. Both Drop and Trunk cable termination types are applicable to APU. The recommended method is Drop cable. APU supports a variety of antenna types: omni-directional, flat panel and bi-directional.
33 Procedure 1-1 Assembling and Mounting the selected Antenna Common Procedure 1. Unpack an antenna box and check if it contains all parts listed in a manual in the box. 2. Prepare the recommended tools for assembly and installation of the antenna 3. Assemble the antenna and bracket kit following the assembly procedure for the selected antenna type. 4. Perform assembly of antenna and bracket as below. Action NTA 2407 (Flat Panel Antenna) Step Action 1.
34 Since the RADOME is not pressurized, there is a drain hole in the connector base plate. The antenna must be installed so that the drain hole remains on the bottom. This drain hole must be kept open so that any moisture accumulating inside the RADOME will be able to drain properly. Figure 3-2 NTA-2407 Antenna Assembly NTA 2400 (Omni directional Antenna) Step Action 1. Make sure that each parts number is the same with the actual parts in the box. 2.
35 3. With the antenna oriented upward, fasten the mounting bracket to the radio using the M6 flat washers, lock washers, and hex cap bolts as shown in the mounting diagram. Lightning Protection The antenna is at DC ground for lightning protection. If the antenna is mounted to a non-conductive structure (e.g. building wall, wooden pole etc.) it should in turn be grounded using practices supplied/approved by the customer.
36 NTA 2412 (Bi-directional Antenna) Step Action 1. Make sure that each parts number is the same with the actual parts in the box. 2. Attach the mounting bracket to the antenna using the 1/4" flat washers, lock washers and hex nuts as shown in the mounting drawing. 3. With the antenna oriented upward, fasten the mounting bracket to the radio using the M6 flat washers, lock washers, and hex bolts as shown in the mounting diagram. Lightning Protection The antenna is at DC ground for lightning protection.

38 Procedure 1-2 Antenna Mounting and Cable Connecting Action Step Action 1. Attach the bracket on the back surface of the APU and thread one flat washer onto each hex bolt. Screw each bolt with the washer into the two mounting holes. Note: Even if APU enclosure has universal mounting holes on the front and rear cover, we recommend that you do not mount two kinds of antenna such as omni-directional and bi-directional type on the front cover.
39 Procedure 1-3 Mounting the APU on the Steel Wire Strand Action Step Action 1. Prior to an installation, check if the strand has the strength to sustain the weight of the APU the weight of the APU or 10 lbs. Note: During placing the cable, do not exceed the maximum rated pulling tension of the steel. After the cable has been placed, tension should be applied to the strand only. Refer to the table of guidelines found in the current NESC Rules 250-252.
40 MAKE SURE THAT ALL BOLTS IN THE ENCLOSURE ARE FIRMLY TIGHTENED. WHEN INSTALLING THE UNIT, CHOOSE A LOCATION THAT PROVIDES A MINIMUM SEPARATION OF 20 cm FROM ALL PERSONS DURING NORMAL OPERATION.

52 CSU Installation & Configuration Mounting and Installation Concept Figure 3-25 CSU Installation Concept on User’s facility By default, CSU is pole mounted. Each unit is shipped with a pole mounting module. WLAN Cable Access Point 6220 NTPM99CA Rel 1.0 Issue 1 Oct.
53 Procedure 2-1 Mounting the CSU on the Steel Wire Strand Action Step Action 1. Prior to an installation, check if the Pole has the strength and stability to sustain the weight of the CSU at a strong wind 2. Please find a mounting tool for installing CSU illustrated in Figure 3-26 3. Place the CSU face (RADOME side) down on a flat surface. 4.
54 7. Adjust the direction of CSU Antenna RADOME toward APU and fasten sufficiently to secure the CSU on the pole. Figure 3-27 Assembling the mounting bracket with a installation tool 8. Adjust the up/down tilt (- 50 º to 50 º) and move the top or bottom of the CSU until the unit is roughly positioned at the correct angle and height. Figure 3-28 CSU Pole Mounting and Antenna Tilting 100 º WLAN Cable Access Point 6220 NTPM99CA Rel 1.0 Issue 1 Oct.
55 Procedure 2-2 Mounting the CSU on the Steel Wire Strand Action Step Action 1. Loosen the EMI cap and slide the CAT5 or 6 cable without RJ45 connector into the hole of the EMI cap shaped like hood. 2.
56 4. Secure the cable in the EMI cap by tightening it with a cable tie. Over-wrap the connectors with black self amalgamating tape or shrink the tubing with sliding over the cable to ensure a waterproof sealing. This is the most crucial step of the installation. If this procedure is not completed, a long-term and complex problems could occur. 5. Tighten the EMI cap securely with the special tool including the product package.
57 Figure 3-32 Connecting CSU and User PC by an Ethernet Cable though POE Injector Mounting Tips • Verify the Line-of-Sight -- Before installing the CSU, make sure a clear lineof-sight exists. Line of sight (LOS) can be defined as each antenna clearly seeing the other antenna, and seeing the remote locations when viewing from the central base location. Be sure to look level with the center of origin of the transmission (i.e., the middle of the antenna). Repeat this procedure from the remote location.
