Murtaza,
You can generate the sector symbols from your basic
geographic data with the demo version of Plan-Opt.
It is designed for GSM and UMTS networks currently, with no
specific support for WiMax, however, if all you need is to create the cell/AP
objects, then with a bit of data manipulation you should be able to do
that.
If you have difficulties, then there is a full help system
in the tool, and a support email address if you still have
problems.
I would appreciate an email to the support address from
your company email account to confirm which network and country you are working
in.
