Overview

The Cisco Aironet 1520 Ser ies Outdoo r Mesh Acc ess Point (h ereaft er cal led the acce ss po int) is a modularized wire less outdo or acce ss p oint desi gned f or use i n a m esh ne twor k. Th e ac cess po int a lso supports wireless client acce ss, point-t o-point bridging, point-to- multipoin t bridging, and point-to-multipoint mesh wir eless conne ctivity.

The LAP1522 model supports two radios (2.4-GHz and 5-GHz) and the LAP1524 model supports up to 4 radios (2.4-GHz, 5.8-GH z, and 4.9- GHz publi c safety ba nd). Both mo dels provide client acc ess without the need for a license. The 5-GHz radios are dedicated to backhaul operations to reach a wired network and the 2.4-GHz radio is used for wireless clients. The 4.9-GHz public safety band radio is used for backhaul and access. The ac cess point can supp ort 6 to 54 Mb/s data rates.

The access po int is m a nufac tur ed in thre e configur ati on s: c ab le, po le mo unt, a nd me sh. The c abl e configuration has three ant enna connectors on the top of the unit, can be mounted t o a cable strand, and supports power-over-cable (POC). The pole mount configuration supp orts two antenn as on the top and bottom of the unit. It can be moun ted to a pole or building wall and sup ports fiber-optic network s and several power options. The Mesh con figuration ha s two a nten nas on the top a nd b ot tom of t he u nit. It can be powered by AC and only supports wireless backhaul communications to reach the wired network. It does not suppo rt h ar d-wi red co mm unic ation s ( ca ble , fiber-opti c, o r E the rnet ) to a wired ne twor k.

The access point is also available as a haza rdous loca tion opti on. When configured , the acc ess point complies with safety st anda rd s for Cl ass I, Division 2, Z on e 2 haz ardo us loca ti ons i n wh ich igni ta ble concentration s of flamma ble gase s, vapors, or liqui ds are not l ikely to exist under normal operat ion conditions). When yo u select th e hazard ous locati on optio n as part of the or dering pr ocess, Cisc o configures the system to conta in t he n ew component s. Two conduit adaptors and assembl y instruc tio ns placed in the shipping box provide inf ormati on and assem bly procedu res.

The access point can also operate as a relay node for other access points not directly connected to a wired network. Intelligent wireless routing is provided by the patented Adaptive Wireless Path Protocol (AWPP). This enables each access point to identify its neighbors and intelligently choose the optimal path to the wired netw ork b y ca lcula ting the c ost of e ach pa th in ter ms of signal str ength and the n umber of hops required to g et to a c ont roll er.

The access point is configured, monitored, and operated through a Cisco wireless LAN controller (hereafter ca lled a controller) as described in the Cisco Wireless LAN Controller Configuration Guide. The Deployment Guide: Ci sco Mesh Netw orki ng Solu tion describes how to plan and initially configure the Cisco mesh network, which supports wir eless point- to-point, point -to-mul tipoint, and me sh deployments. The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco Wireless Control System (WCS) network management system to manage the controller and the associated access points. The access point supports hardware-based advanced encryption standard (AES) encryption between wireless nodes to provide end-to-end security.

The access point provides 5-GHz back ha ul c apab ilit y to li nk wi th a not her ac cess point to r eac h a wir ed ne twork connection or to provide repeat er operat ions for other access points.

Network Deployment Examples

The access point plays one of two primary radio roles: a root access point (hereafter called a RAP) or the access points that relay their wireless connections to the controller are called mesh access points (MAPs). When the access point has a wired Ethernet, fiber-optic, or cable connection to the controller (through a switch), th e ra dio role is ca lled a RAP. A RAP is a parent node to any br idgi ng or m e sh network. A controller can support one or more RAPs, eac h one parenting the same or different wireless networks. There can be more th an one RAP fo r the same m esh ne twork f or re dun dancy. Both RAP and MAP access points can su pport wi reless clie nts using the 2.4- GHz rad io.

Note The access point must be configured as a RAP in the controller, whereas the MAP role is a default

setting.

When the access point does not have a wired Ethernet, fiber-optic, or cable connection to the controller, the radio role is called a MA P. The MAPs have a wireless con nection (t hroug h the back haul inte rface) to other MAPs and finally to a RAP with an Ethernet or cable connection through a switch to the controller. MAPs can also have a wired Ethernet connect ion to a lo cal LAN and serve as a bridg e endpoint for t hat LAN (usi ng a p oin t-to- poin t or po i nt-to- mul tipoi n t br idge conn ec ti on).

Network Deployment Examples

Mesh Network

148439

The access points are typically deployed in a mesh network configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network. In the mesh network, the links between the access points are referred to as the

backhaul links.

Intelligent wireless routing is provided by the patented Adaptive Wireless Path Protocol (AWPP). This enables each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with the wired network co nnec tio n by c alcul at ing the co st of e ach pat h in t erm s o f sig na l stre ngth a nd the number of hops required to get to a controll er.

tower is largely a matter of coordination. Each person sh ould be assign ed to a specific tas k and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watc h for sign s o f troub le.

4. When installing the access point and antennas, remember:

a. Do not use a meta l lad der. b. Do not work on a we t or wi ndy day. c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or

jacket.

5. Use a rope to lift the access point. If the assembly starts to drop, get away from it and let it fall.

6. If any part of the antenna system should come in contact wi th a power line, do not touch it or try to

remove it yourself. Call your local power company. They will remove it safely.

If an accident should occur, call for qualified emergency help immediately.

Avoiding Damage to Radios in a Testing Environment

The radios on outdoor units (bridges) have higher transmit power levels than radios on indo or units (access points). When you t est high power radios in a lin k, you must avoid exceeding the rec eiver’s maximum receive input level. At levels above the normal operatin g range, pa cket erro r rate (P ER) performance is degraded. At even higher levels, the receiver can be permanently damaged. To avoid receiver damage and PER degrada ti on, you ca n use o ne of t he fol lowing t echn ique s:

• Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least

25 ft (7.6 m) to avoid PER degradation.

Note These distance s assum e fre e space path loss and ar e cons ervative estimate s. Requi red

separation distances for damage and performance degradation levels in actual deployments are less if conditions are not non line-of-sight.

• Reduce the configured transmit power to the minimum level.

• Use directional antennas, and keep them away from each other.

• Cable the radios together using a co mbination of attenuators, c ombiners, or splitters to achie ve a total

attenuation of at least 60 dB.

For a radiated test bed, the foll owing equation descr ibes the relationships among transmit po wer , antenna gain, attenuation, and receiver sensitivity:

txpwr + tx gain + rx gain - [attenuation due to antenna spacing] < max rx input level Where: txpwr = Radio transmit power level tx gain = transmitter antenna gain rx gain = receiver antenna gain

For a conducted test bed, the fol lowing equation describes th e relations hips am ong transm it power, antenna gain, and rec eiver sensitivity:

txpwr - [attenuation due to coaxial components] < max rx input level

Caution Under no circumstances should you con nec t t he ant enna por t from one ac cess po int to the ant enna port

of another access po int wi thou t using a n RF att enua tor. If you connec t a ntenna ports, y ou mu st no t exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm, or damage to the access point can occur . Using attenuato rs, combiners, and splitters hav ing a total of at least 60 dB of att enuation ensures that the receiver is not damaged and th at PER perf orma nce is not degrade d.

Installation Guidelines

Because the access point is a radio device, it is susceptible to common causes of interference that can reduce throughpu t a nd ra nge . Foll ow these b asic gu ide lin es t o ensu re the b es t pos sibl e perfo rm an ce:

• For information on planning and initially configuring your Cisco Mesh network, refer to the

Deployment Guid e: Ci sco Mes h N etw or king So lut ion.

• Perform a site survey before beginning the inst allat ion.

• Install the access point in an area where structures, trees, or h ills do not obstruct rad io signals to and

from the access point.

• The access points can be installed at any height, but best throughput is achieved when all the access

points are mount ed at the same hei ght. We recommends installi ng the a cce ss p oints no high er tha n 40 feet to allow support for wireless clie nts on the gro und.

Note To calculate path loss and to determine how far apart to install access points, consult an RF planning

expert.

Chapter 2 Mounting Instructions

Site Surveys

Every network application is a unique installation. Before installing multiple access points, you should perform a site survey to determine the optimum use of network ing components a nd to maximize range, coverage, and network p erfor ma nce.

Consider the following operating and environmental conditions when performing a site survey:

• Data rates—Sensitivity and range are inversely proportiona l to data bit rat es. The ma ximum ra dio

range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases.

• Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio

range. As a general ru le, ra nge in cr ease s in p rop ortio n to an te nna he ig ht. However, do not place the antenna higher than necessary, because the extra height also increases potential interference from other unlicensed rad io sy stem s a nd de cr ease s th e wir eless c overage f rom t h e gro und .

• Physical environment—Clear or op en are as pr ovide b ett er r ad io r an ge t han cl os ed or filled ar eas.

• Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of

wireless devices. Av oid locating the devices in a location wh ere th er e is a n ob struction between the sending and receiving ante nnas.

Configuring a Bridge Group Name

The bridge group name (BGN) controls the association of the access points to a RAP . BGNs can be used to logically group the radios to avoid different networks on the same channel from communicating with each other. This setting is al so use ful i f you have more tha n on e R AP in yo ur n etwork i n the s am e are a.

If you have two RAPs in you r network i n th e sam e a rea (f or mo re cap aci ty), we r ecom me nd tha t yo u configure the two RAPs with the same BGN, but on different channels.

The BGN is a string of ten characte rs maxim um. A factory -set bridge group name (NU LL VALUE) is assigned during manufacturing. It is not visible to you, but allows new access point radios to join a network of new access point s. T he BG N ca n be r econfigure d f rom the Con trol ler CLI a nd G UI. Aft er configuring the BGN, the acce ss point reboots.

The BGN should be c onfigure d ver y ca reful ly on a l ive network. You should always start from the farthest node (last node) from the RAP and move towards the RAP. If you start configuring the BGN in a different locatio n, th en the a c cess p oi nts beyond t his po int (far ther away) ar e d rop ped, as t hey have a different BGN.
