5 Coverage Specification

Deakin University requires that all teaching, academic, student congregation areas, staff occupied spaces, public-

transport waiting areas on-campus and adjacent to campus, and nominated external open areas can access the

Deakin Eduroam Wireless Network with adequate reception and data throughput.

5.1 New buildings and Renovations

All new buildings and renovations are to provide coverage throughout the new or renovated areas.

To ensure that adequate wireless reception is achieved Network Engineering must approve proposed locations for

the installation of WAPs. It is therefore a requirement of building project planning that Network Engineering are

provided with a scaled PDF of the area/s to be covered. Information to include:

• Details of the proposed wireless coverage

• Expected client density (standard/high)

• Proposed building materials (eg. Wall thickness)

• Location of air conditioner duct work and hanging fixtures

Consultant to provide detailed radio survey using the prescribed software tools (refer Section 12 below) and provide

back to Network Engineering a PDF document indicating proposed WAP positioning and coverage.



6 Performance Specification

All serviced areas must deliver the minimum signal strengths specified below in both the 2.4 GHz and 5 GHz bands

and provide IEEE 802.11 a, b, g, n and ac services.

The best practice guidelines for both wireless coverage and proximity/location services shall be adhered to in all

scenarios. Location service accuracy to be within 5 meter.

The University has identified four distinct areas requiring differing design rules. These are high density, medium density,

standard density and outdoor installations. The following definitions apply. In all circumstances the approved latest

technology IEEE 802.11 a/g/n/ac technologies shall be utilized.

6.1 High Density

Refers to areas whose usage is predominantly for teaching areas with a capacity above 50 users and where students

congregate such as cafeteria and library locations. The design for these areas is to accommodate a minimum average

density of two user devices (one active) per square meter of relevant floor area and shall delver a minimum -67 dBm

signal strength in these areas.

6.2 Medium Density

Refers to areas whose usage is predominantly for teaching areas with a capacity between 20 and 50 users. The design

for these areas is to provide a service offering of no less than -67 dBm signal strength with a minimum of two access

points visible at this signal level.

6.3 Standard Density

Refers to areas that are predominantly used for administration, staff offices and adjacent area such as a corridor or

multi-level carpark. These require a service offering of no less than -67 dBm signal strength.

6.4 Outdoor Areas

Refers to public-transport hubs on or adjacent to the campuses, transient areas between buildings that are frequented

by students and open carparks. These require a service offering of no less than -67 dBm signal strength as per standard

density.

Minimum throughput for all deployments at 4mb/s



7 Wireless Access Points (WAP) and Antennae

Only Deakin standard WAPs and antennae shall be used.

7.1 Internal

The current prescribed WAP for ceiling mount indoor use is a Cisco WAP, product code AIR-CAP2802I-Z-K9.

7.2 External

For external use there are several antenna and WAP options possible, generally built around the AIR-CAP2802E-Z-K9

model. To determine which antenna option to use discussion with DeS AVN will be required.

7.3 Standard Outdoor

For standalone outdoor deployments IW3702-2E-Z-k9 V03

For building installation with external antennas AIR-CAP2802E-Z-K9

8 Installation

8.1 WAP installation

WAPs shall be installed 2.4 to 2.8 meters above floor level. The WAP shall be positioned such that the indication lamps

can be easily viewed.

The WAP should be ceiling mounted as per AirMagnet design document. If a WAP with internal antennas (2802i) needs

to be wall mounted it must be mounted on an Oberon Bracket (Part No. 1011-00/8A). Otherwise a WAP with external

antennas will need to be mounted on the wall (2802e)

WAPs and data outlets shall not be placed in stairwells, ceiling spaces or be enclosed. WAPs must be installed well

clear of all metal duct work and other ceiling fixtures. Where duct work is present WAP must be mounted well below or

relocated.

WAPs shall not be in positions where it will be difficult to access or cause OHS issues during maintenance.

8.2 WAP data connection

Every WAP shall be installed with a single data point. The data point shall be installed with the bottom edge of the

data point plate 50 mm above the WAP’s top edge.

Each WAP unit shall be connected to the Deakin Network using a 0. 5 meter Panduit CAT6 white patch lead. Excessive

patch-lead length, e.g. wound several times around the WAP, or loose hanging is completely unacceptable, nor shall it

be draped nor cause a personnel snagging hazard.

In the event that a WAP is to be connected to a MUTOA or in line socket the patch lead shall be of length that ensures

that the patch lead is not pulled taught. Also, if connected to a MUTOA the connecting patch lead shall be concealed

immediately on exit from the MUTOA and WAP, at no point shall the patch lead drape in the path from MUTOA to

WAP.

8.3 WAP Labelling

All WAPs shall be labelled with the Deakin name for the WAP and MAC Address. The label must be of a size that can be

read from floor level. The name shall have the following syntax:

<campus> - <buildingfloor> - <room> - ap

- <nn>



e.g. f-ad4-202-ap-01

If the WAP is connected via a MUTOA an additional label shall be attached with the data point number as connected

on the MUTOA.

8.4 Post installation documentation

On completion of an install contractors are to provide DeS with a marked up floor plans showing WAP names, MAC

address, data point numbers and switch port numbers.

9 Wireless Bearers and Meshes

In buildings with no existing LAN infrastructure to act as back haul for the WAP’s and under direct consultation with

AVN representatives a wireless mesh installation shall be used. The installation is to adhere to other specified

standards within this document regarding product selection. The mesh will utilize the 5 GHz band to provide data

backhaul and the 2.4 GHz for user services.

2.4 GHz user service signal strength shall conform to the same performance standards (Section 7) as applicable to the

relevant area category.

5 GHz mesh backhaul shall deliver a minimum SNR of 31 dB.

10 Central Infrastructure

10.1 Controllers

The controller platform used for the WAPs are the Cisco 5520 series Wireless LAN Controllers (WLC). The applicable

software version will be specified by Network Engineering.

10.2 Management systems

The wireless LAN management system used for management and monitoring is the Cisco Prime Infrastructure (CPI)

https://cpi.core.deakin.edu.au .

11 Radio Survey Tools

The University accepted radio survey tool is the Air Magnet Survey Pro by Netscout. Current version of this tool is

v8.7. This tool shall be used to generate all planning and survey documentation. Both planner report and raw

AirMagnet files will be provided for Network Engineering to sign off.
