Hello,
Can anybody share their knowlege about portable test transmitters which could be connected to indoor antenna to simulate coverage in indoor environment.
One thing is to calculate required EIRP from the antenna which is based on link budget, the other thing is to make sure that there will be no dead spots of coverage indoors (Walls, floors, reflections, scattering... a lot of things to keep in mind) - none prediction tool/speradsheet is 100% accurate.
I know that "Tems transmitter" is quite popular, but it is not supported by ASCOM any more.
Transmitter should have output power from -10 dBm to about +25 dBm. It should be portable without need of external power supply. Great thing would be if I could program BCCH channel, so that RSSI could be mesured with Tems Pocket for post processing.
Maybe someone has experience of using theese CW generators? http://www.ptsyst.com/FSG-B.pdf
I have been dealing with analog repeaters deployment (with composite output power up to 18 dBm), but there are some bigger projects coming with dedicated BTS/NodeB and I'm a bit worried - don't want to make expensive mistakes.
