PLANNING AND DESIGNING
Planning with EWS
Planning with EWS is simple by using the visual monitoring method. With
the ability of combining the topology with floor view it enhances the
usage of applying diagram to indicate the location of the Access Points.
Planning
EWS
Web with
Interfaces
Using the floor View, images of layout can be imported and allow the indication of
the position of the Access Point
Planning with EWS
Using the Map View which uses google map, it allows ease of Outdoor
application. Access Point can be emplace to indicate the position. Default
location of map is Taiwan until the EWS is able to get a gateway to the
internet to set its actual location at site.
Manage APs with Ease: Cluster Management
Cluster A
Cluster B
The system can group a variety of wireless settings into single
repository so users can just assign this collection of settings to specific
AP upon discovery. It will save time on tedious repeated configuration
steps on individual settings and allows for fast deployment.

Fast Handover
Behavior of any wireless Client - Once it is associated to the
1st AP, it will “STUCK” to it unless it disconnect itself.
RSSI level can be set to facilitate wireless clients to handover
to adjacent AP(s) with better signal. This feature can assist to
maintain the best available signal quality across multiple AP
within the wireless network.
RSSI: <(-70dBm)
RSSI: -60dBm
Site Survey – Indoor
Site Survey Tools - InSSider
First step to site survey using InSSider to conduct surround scan to check
what channels have been used before implementing fast handover or any
implementation of POC.
NOTE: If the 2.4GHz radio is set to “Auto”, it will scan in sequence of 1,6,11
While for 5GHz, it will scan all available channels depends on the country domain
that you set.
Site Survey for Fast Handover
Step 1:
Set one AP at RSSI at -70dBm. Start walking from the AP.
Using InSSider to scan the AP coverage beyond the preset -70 dBm
eg. -75dBm
AP1
AP1
-75dbm
RSSI set at: -70dBm

Step 3:
Using a portable device, moving from AP 1 to AP 2 browsing of
internet and video streaming should gives a smooth transition
with no lag on image.
NOTE: To verify the site survey,
please use a Smart phone (with
InSSider APPS).

Fast Roaming
With fast roaming, a full authentication method is required to establish the
initial client connection, after which the fast roaming technique can
subsequently be used when roaming between APs to minimize
perceptible delay during re-association (by distributing and caching
PMKSA on neighbor APs). The techniques optimizes latency-sensitive
applications such as wireless voice over IP (VoIP).
Fast Roaming
This Method of Needs a RADIUS Server to facilitate the authentication.
NOTE: Fast Roaming only works with Encryption WPA/WPA2 Enterprise
and above.
High Density Wireless Network
Using EWS to control wireless Access Point in High Density area such
as Auditorium with 320 seats by using Band Steering, Client
limitation and traffic shaping. Distributing maximum 54 wireless
client to each AP
Calculations:
 Total Bandwidth : 20M
 No. of AP : 6
 Bandwidth allocated per AP: 3MB
 Client allocated per AP: 54
 Client allocated per radio band: 27
Traffic Shaping
Traffic shaping allows you to limit the upload and download speed at the AP’s
LAN port and also speed allocated to each RADIO bands.
2.4GHz
Download
Upload
5GHz
Traffic Shaping
Using Traffic shaping to control the bandwidth of the Access Point in the
cluster to allow even distribution of the allowable bandwidth.
Recommendation: You may want to limit upload speed.
Traffic Shaping
Coordinating with the EWS is the L2 function which you fixed the
bandwidth for the individual port to make sure that each port is using
the same bandwidth.
Client Limit
Setting Client limit to control the number of user connecting to
the Access Point.
NOTE: The more client you set
each band, the lesser
bandwidth
is given to each client.
For Email, Twitter, Facebook
and Normal internet browsing
is 256 kbps.
Maximum Concurrent Client
To allow better control per AP traffic and loading, it is crucial to
allocate and distribute the bandwidth
EWS310AP
Up to
60 clients
**30 per band
EWS320AP
Up to
80 clients
**40 per band
Band Steering
Band steering steers the 5GHz-compatible clients to 5GHz band by
responding only to the 5GHz association requests and not the 2.4
GHz requests. It helps to leave more bandwidth for 2.4GHz devices
operating in 2.4GHz band.
Band Steering
Using Band Steering to load balance the number of the wireless client
connecting to the Access Point by identifying the 5Ghz user to automatically
connect to the Access Point via 5Ghz and off loading the 2.4Ghz band.
NOTE: In order for the
Band steering to work,
both radio have to be set
with SAME SSID and
encryption.
Band Steering
By checking the Active Client Table below, you would be able
to identify the which client is associated to each radio band.
AP status Monitoring
During Planning the EWS provide detail visual monitoring of the Access Point.
By Analyzing these statistic you will be able to understand the usage pattern and
do Load Balancing. You may standby additional AP to cater for peak hours.
