Checking Connectivity
The following example assumes the setup below:
• For information on how to setup your 245U-E-A radio
device refer to section 3.25 of the User Manual
Device Mode: Access Point (AP)
IP address: 192.9.200.74
System Address (SSID): system
Device Mode: Client (STA)
IP address: 192.9.200.75
System Address (SSID): system
support@tabateq.com
Connectivity information: AP Webpage
Shows that this AP is connected to device IP
192.9.200.75
Connected on Channel 149
Connectivity Rate is 18Mbps.
Note: this is NOT the actual
throughput but max possible RADIO
throughput. Actual throughput will be
roughly half this but must be tested
(see later section)
RSSI = Received Signal Strength = -74dBm
BGND = Background Noise = -84dBm
RSSI Connectivity Rate
-74dBm (or stronger) 54Mbps
-90dBm 18Mbps
-94dBm 6Mbps

Checking Channel Utilization
The following example assumes the setup below:
• For information on how to setup your 245U-E-A radio
device refer to section 3.25 of the User Manual
Device Mode: Access Point (AP)
IP address: 192.9.200.74
System Address (SSID): system
Device Mode: Client (STA)
IP address: 192.9.200.75
System Address (SSID): system
Channel Utilisation gives a visual display of how busy the current channel is over a given time period.

Checking Channel Utilization
Device Mode: Access Point (AP)
IP address: 192.9.200.74
System Address (SSID): system
Device Mode: Client (STA)
IP address: 192.9.200.75
System Address (SSID): system
Channel Utilisation gives a visual display of how busy the current channel is over a given time period.
E.g. 1 Relatively Quite Channel
E.g. 2 Relatively Busy Channel

Checking Channel Utilization
Click on “Channel Survey” from the device Home Page
• Channel Utilization shows both seconds, mins and hours. It
also include the average background noise for each time
interval
• On average, you don’t want your channel utilization to be
higher than around 75%
• If you don’t have a lot of traffic on your system, this value
should be relatively low. If it’s high it could indicate the
presence of other interfering systems.

Throughput Testing – Interpreting the result
The table below shows the expected results for both internal and external throughput testing.
This is an example of internal throughput testing, which always yields slightly lower results.
Your internal results should match up relatively closely to the tables values below.
