Goals

Site Survey Goals:
This document is intended to provide the customer with a design for an upgraded
“Lightweight” AP Wireless Local Area Network (WLAN) proposed at the customer s existing
Lightweight customer’s
ground floor site located at 702 Sequoia Springs Parkway, in Sequoia City California. This
WLAN will provide 802.11a/b/g wireless VoWLAN ready coverage using the customer
preferred Cisco 1240a/g Wireless Access Point (WAP) in “lightweight” mode along with
controllers, for all customer specified indoor work areas of the ground floor, and stock room
deck. It is i
d k I i primarily i il intended to support 802 11b/ d
d d 802.11b/g data-only wireless b
l i l barcode scanners, and
d d
mobile wireless label printers at this time. Additionally, the customer requires this WLAN to
be designed to accommodate a probable future deployment of VoWLAN push-to-talk
telephones, and 5 gHz frequency band client devices.
Draft a preliminary design based on customer provided floor p
p y g p plan, using advanced
g
computer modeling and simulation techniques for complete, reliable, data and VoWLAN ready
RF saturation at -67 dBm or better throughout the in-scope area.
Refine the preliminary design parameters using observations and field measurements of RF
signal penetration and coverage area at key representative locations.
Identify any required WAP antenna, controller wireless mgmt software and
WAP, antenna controller,
enclosure/accessory types, locations, numbers, mounting requirements and
recommendations, for upgraded WLAN infrastructure equipment along with new Ethernet
cable drop locations for the proposed project.
Use RF spectrum analysis and wireless protocol analysis to identify and report current or
foreseeable effects of any existing significant i t

Assumptions
Assumptions:
In order to accommodate an extremely short project timeline, the customer may have already
begun implementing some of the recommendations noted here, while this document is being
drafted.
The
Th customer requires a WLAN design t support th use of 802.11b/g data clients at this
t i d i to t the f 802 11b/ d t li t t thi
time, and VoWLAN phones and 5 gHz clients later. Target minimum signal strength design
threshold conforms to the Cisco VoWLAN guideline of -67 dBm or better in all areas of scope.
The customer will use “LightWeight” AP technology with a pre-existing local WLC (controller)
to configure and manage the upgraded WLAN.
All hard walls will continue to conform to the provided campus plan diagrams used in this
survey, for the expected life of this network.
No additional authorized or unauthorized 802.11, 802.11b, 802.11a, 802,11g, or 802.11n
APs, clients, peer networks or other transmitters or emitters (like Bluetooth applications,
cordless phones/headsets, microwave ovens or other non 802.11 devices using the 2 4 gHz
phones/headsets non-802 11 2.4
and/or 5.2 gHz frequency bands) will be installed or used in or near the in-scope area for the
expected life of this network.
No layer 3 client roaming is required at this time.
The effects of non-WLAN RF emitters, obstructions, reflectors and refractors like furnishings,
partitions, equipment machinery
partitions equipment, machinery, stored stock and other undefined items that may be moved or
added after the site survey can not be accounted for, and may negatively effect WLAN
performance.
RF noise & interference in the 2.4 & 5.2 gHz band from nearby and internal sources not a
part of the proposed WLAN will remain constant or decrease in severity.
There is no requirement for concentrations of greater than 25 wireless data clients, or more
than 8 VoWLAN phones on any single AP.
All APs specified in this document will connect to the customer network via Cisco Catalyst
switch based power over-Ethernet (PoE), or mid-span power injectors, so no local AC power for
APs is required.


Strategy & Results Summary
Strategy:
Use floor plan diagram to model projected RF propagation using computer simulation. Base a
preliminary WLAN design on this data, then adjust that design per on-site observations, RF
propagation testing and measurement. Design for 802.11a/b/g clients, including VoWLAN phones.
Use the Cisco 1242a/g LWAP throughout, with a pre-existing local WLC along with Cisco WCS
management system to maintain optimum performance with minimum administration labor. Use
external 2.4 and 5.2 gHz low gain omni directional, and some medium gain directional antennas
throughout the site. Wall and overhead bracket mount the APs, with optional locking steel
enclosures in areas where physical security may be a benefit.
p y y y

Results:
WirelessOne Designs testing, modeling, simulation and analysis found the size, shape, design,
construction, and obstructions on the customer campus should allow for good coverage within the
minimum design threshold target of -67 dBm or better signal strength at 36 MB connect rate and
67 strength,
10% network load or less, when this recommended design is implemented exactly as described in
this document. The ambient RF interference & noise level is moderate to high in all areas of the
floor. This interference is from an unusually wide variety of sources. Please see the spectrum
analysis section for details. Modern wireless broadband communications standards like
802.11a/b/g/n
802 11 /b/ / are quite resilient and resistant to interference. High utilization in the 2 gHz b d
l d f h l h 2.4 band
was present from some applications during the spectrum analysis sweep. Common-channel
interference from pre-existing internal WLAN sources is present, but much or perhaps all of this will
disappear when the old WLAN is decommissioned and replaced by a properly channelized network.
But if not, this interference can increase error rates and retransmissions, so corresponding
, , p g
throughput could decrease, as utilization in the new WLAN becomes heavy. WirelessOne Designs
recommends careful periodic review of error/retransmission statistics as well as other alerts at the
WLAN management level (WCS) to identify any problem trends early.

Spectrum Analysis: Overview

Test Parameters:
WirelessOne Designs performed spectrum analysis sampling of the in-scope areas of this project for the purpose
of identifying and quantifying potential interference in the 2.4 & 5 gHz WLAN frequency bands. The strategy was
to
t use b i protocol analysis t h l identify 802.11a/b/g networks, and RF spectrum analysis t id tif and
basic t l l i to help id tif 802 11 /b/ t k d t l i to identify d
evaluate non-802.11 interferers sharing the same unlicensed frequencies. The equipment and software used
included a Windows tablet computer running, Cisco Spectrum ExpertTM using its native client adapter card, with
external multi-frequency antenna, and NetStumblerTM using the internal Intel 802.11a/g/n adapter.

The Cisco Spectrum Expert TM was used here primarily for it’s ability to capture, replay and report 802.11a/b/g,
here, it s capture 802 11a/b/g
and other interference in the 2.4 & 5 gHz frequency bands, and to identify many interfering sources by type. The
primary causes for concern with the existing customer network include:
1) Most WLANs in the 2.4 gHz band not maintaining proper separation between APs using same RF channels.
Most APs detected were crowded into Ch 1, with a couple on Ch 11. This results in unnecessary interference
with each other
other.
2) Some WLANs in the 2.4 gHz band are using overlapping RF channels. This results in interference with non-
overlapping channels on both sides of the “off-key” channels.
3) Several non-WiFi transmitters in the 2.4 gHz band have potential to degrade performance on the new WLAN.
This is because non-WiFi equipment doesn’t use the kind of “polite” protocols that WiFi networks use, like
listening for traffic before transmitting. And they also may keep their transmitters on a greater percentage of
transmitting
the time than most WiFi networks, making it even harder for neighboring WLANs to get on the air. The 5 gHz
bands were wide open and interference free, however.

Protocol analysis recorded the presence of 30 sources of WiFi transmissions, all in the 2.4 gHz band. This is a
fairly high level of competition for the 2.4 gHz frequencies, but when they are not all properly channelized so
they can be good neighbors, the result is less performance than you paid for. Internal non-802.11 WLAN
interference from sources like microwave ovens, production related equipment, Bluetooth hardware, and cordless
phones/headsets may or may not be addressable by the customer, depending on sociological as well as technical
issues. WirelessOne Designs recommends leveraging the 5 gHz bands as much as possible.

Protocol Analysis: Overview

Protocol analysis is included here because it can often be helpful in identifying the use or owners of the
802.11a/b/g transmitters on the air in the customer WLAN environment. However, only 802.11a/b/g transmitters are
reported on. None of the other devices or noise sources in the 2.4 and 5 gHz frequency bands are reported. The tool used
to collect the following data is NetStumblerTM version 0.4.0, a commonly available simple WLAN analysis software application.

The data is shown sorted in order by rf channel. All transmitters heard while walking throughout the given floor are listed,
and some may be located outside customer property. A very weak signal on all floors may help identify outside transmitters.

Protocol Analysis: Detail
These networks are displayed in ascending order by radio frequency channel

These two peer components of a possible wireless video screen net may cause high levels of interference due to very high
network utilization. Stationary video app data is better on a wire. The non-secure “public WiFi” & “iphoneModem” WLANs are
potential rogue network security breaches if connected to the customer wired network, and should be located and investigated.

It is not possible to reuse the same non-overlapping channel this often in a space this size without causing
serious common channel interference resulting in degraded throughput.

Only channels 1, 6 and 11 in the 802.11g 2.4 gHz band are non-overlapping. Use of any other channels
interferes with the closest non-overlapping channels.

It is not possible to reuse the same non-overlapping channel this often in a space this size without causing
serious common channel interference resulting in degraded throughput.


Propagation Testing: Overview

WirelessOne Designs used the Ekahau Site Survey TM release 4.5 from among the most advanced
generation of site survey tools to model the campus construction on the proposed floor plans, then
simulate RF propagation with various AP configurations and antennas. The stage shown in this
antennas
section is the on-site propagation measurement, in which actual results are compared against
simulations, allowing the simulations to be refined. This step provides for an accurate WLAN
performance design based on both computer simulation and field measurement for the property.
The following page shows selected actual raw as-measured RF signal strength samples from key
locations which were used to refine the final design in this site survey.
l i hi h d fi h fi l d i i hi i

Note: The site survey AP used for the following testing was configured for 50/30 mW transmitter
power for 2.4 gHz CCK/OFDM transmitters. Antennas used were one 2.15 dBi ‘rubber duck’ dipole,
and one 8.5 dBi directional patch for 2.4 g
p gHz, and two 3.5 dBi ‘rubber duck’ dipoles for 5 g
p gHz.

WirelessOne Designs found signal blocking and multi-path interference due to tall machinery in the
Production section, and signal attenuation due to shelving loaded with stock to be acceptable, thus
allowing effective propagation of WLAN microwave signaling. This allows the entire area of scope
including three connecting hallways to be effectively covered with eleven APs.

General installation guidelines:
Prime APs according to IOS commands in Cisco Quick Start Guide, or via DHCP/DNS. These low power microwave signals cannot penetrate metal, so
avoid metal objects or surfaces as much as is practical. Install Cat 6 cable from PoE switch or mid-span PoE injector in IDF to Ethernet drop location,
terminated with RJ45 biscuit block at each location. Connect AP to biscuit block with short patch cable. Please dress patch cables and any other
wiring to prevent them from hanging between an antenna and any potential client devices.
