Golden Rules for collecting Data during drive test
1- Choose the site under surveying to be above the clutter and repeat types of the clutter you would be looking at.
2- Any thing with clutter less than 100 is not enough.
3- Make sure that the GPS surveying option is the same as the one used where the drive test is being performed.
4- Make sure that the Dautch value of the GPS is the same as the one set for the country where the drive test is being made.
5- Better collect data in the format of, Degrees: Decimal Points Degrees.
6- Every 6 degrees you move result is one point change in the whole picture the UK being the reference point at 30, To the left it increases and to the right it decreases.
7- Sampling rate, 40 Samples per 40 wavelengths. To reduce the effect of Radio fading.
8- Sampling can be in Distance and Time. Better do it in Distance especially if you are driving in traffic jams.
9- Do not drive away too much from the site.
10- Drive in to the Site passing through the clutter as well as crossing the clutter
11- Try and drive many roads close to the site unless the clutter is so important.
12- Try to avoid driving the same road twice.
13- Do not drive over a bridge or in to a tunnel inside a clutter area, otherwise take that parts of data a out of the data file collected for this clutter.
14- Make short calls and Long calls, Short calls is the average duration by customers, short calls are to know whether calls will survive the setup and the termination successfully, it also determines the setup time…
15- Long calls are to test the hand over capabilities.
16- Adjacent channels are channels with coverage of 9db more than the serving cell.
17- The co-channel interference is interference from channels have frequency lower the serving channel.
18- For the adjacent channel you could be served from this adjacent channel but the system can not read it and it gives the name of another channel
19- The 6 neighboring cells are those who are listed in the scan list these do not mean that these are the only channels that the phone can see.
20- You have to make sure of the values you are getting out of the surveying equipment do actually make sense.
21- Know the exact power out of the antenna, ERP level, (Effective Radiation Power).
22- Everything about the antenna conditions, during the test time should be reported in the final report.
23- Weather conditions should be reported as well.
24- Know the distance and direction of any buildings blocking your way.
25- Finally, report all sorts of problems.
