- Can I detect pilot pollution using only my UMTS phone interface? How?

- I just upgraded my X-TEL TDMA system to GSM. I know GSM reports signal quality as RX Lev and I am wondering if there is a way that I can see this information in -dBm also?

- My company is thinking of doing some GSM load testing with multiple phones. We would like to connect 6 phones simultaneously with one phone doing an FTP data session test. Our purpose is to evaluate performance degradation with data in congested downtown areas. Can you equipment make calls on 5 phones at the same time another phone is doing a GPRS FTP test?
- We are upgrading the software. What are the minimum requirements recommended by X-TEL for the new software?
Can I detect pilot pollution using only my UMTS phone interface? How?
Yes you can. We have pilot pollution algorithms based on the phone data. Those algorithms use the EC/IO and RSCP values reported by the phone and compare them with configurable parameters to determine whether there is pilot pollution or not. This information is available on the “WCDMA Pilot Pollution – Phone” Screen
If I use my scanner, will that tell me pilot pollution as well? How?
Yes. We have pilot pollution algorithms based on the scanner
data. The scanner must be configured on the same channel number
as the phone so we can use the measurements to detect pilot pollution.
There is pilot pollution when the difference between the 5th and
6th strongest scrambling code of the scanner is within a configurable
threshold. This information is available on the “WCDMA Pilot
Pollution – Scanner” Screen
I just upgraded my X-TEL TDMA system to GSM. I know GSM reports signal quality as RX Lev and I am wondering if there is a way that I can see this information in -dBm also?
Yes there is --depending on what display screen you have open. For example, if you open the GSM Phone Status Screen you can toggle RX Lev to RSSI by clicking on the field with your mouse pointer. Try experimenting with this and see if it helps.
Is there any easy way to merge multiple data files? I often collect 4-6 files over the course of a day.
There are two options. First, you can use the Merge utility located under the File menu in the X-TEL data collection software. Or you may simply append to files when you start new collection runs. You will see an “Existing Tests” window when you execute the “Start Test” command. Simply choose the test you want to append to and start collection.
I just installed my new AMR GSM test mobile, how do I enable it in the software?
Once you have installed all the manufacturer's drivers, go to "Options -> USB Interface" in the main menu screen and select the device you just added, you must specify it's corresponding serial port. To find what port the device is using, go to "Start->Settings->Control Panel->System->Hardware->Device Manager", in the Device Manager screen you will Ports, open the Ports seccion and check what port your phone is using(usually shows a Motorola Netmon device).
Tomorrow I need to perform FTP testing. Will I be able to playback the FTP speed performance after the test and if so, how?
Yes, you can. When you playback the collected GPRS data, any FTP
data collected during that test will automatically be played back
to the screen. You can always watch the FTP session progress opening
the FTP Status Screen in "Windows -> FTP Data Speed Measurement
-> FTP Data Speed Measurement" option in the main menu,
in both collect and playback mode.
How do I view the new AMR Codec parameters?
Go to "Windows -> GSM -> AMR Codec Display", this screen provides information for both uplink and downlink of the last 10 AMR frames.
My company is thinking of doing some GSM load testing with multiple phones. We would like to connect 6 phones simultaneously with one phone doing an FTP data session test. Our purpose is to evaluate performance degradation with data in congested downtown areas. Can you equipment make calls on 5 phones at the same time another phone is doing a GPRS FTP test?
To configure the calls go to
"Phone->Call Processing" and program the phone numbers,
cicles and call duration for each one of the 5 phones. Then setup
a regular connection using the GPRS in the Windows Network Connection
screen (in XP you may open this screen by selecting "Start->Settings->Network
Connections").
We are upgrading the software. What are the minimum requirements recommended by X-TEL for the new software?
The minimun requirements for
doing data collection are:
Intel PIII 500 or equivalent.
64MB of RAM
Microsoft Windows 98/ME/2000/XP*
2GB+ of free hard disk space (for swap, temporary files, and collect
files)
The recommended specs for PostProcesing are:
Intel PIII 1Ghz or equivalent
512MB of RAM
Microsoft Windows XP Professional
5GB+ of free hard disk space.
Fast HDD
* Windows XP/2000 is required by Motorola USB Phones
