Hello OpenBTS Discuss! We're currently setting up our first field deployment using the GSM900 spectrum, but the regulatory agency giving us permission has asked that we Notch out the 941-944 MHz frequencies for tx. I don't see any obvious way to block out these frequencies in the config, so I have to assume we'll need to modify source in some way. Any ideas on an easy way to hurdle this limitation? I feel like there are a lot of possible solutions (filtering on the USRP, wire filtering, so on) and I have little intuition on the best way to go. Thanks! |
