Welcome to band.radio!
- This site is intended to be a repository for all of my projects concerning radio frequency (RF) technology i.e. amateur radio (HF/VHF/UHF, DMR), software defined radios, 3GPP wireless network standards such as LTE, NR. I have also written several gudies & articles, including 3GPP standards, Qualcomm Modem-RF systems, where I go in depth on how they’re used in commercial networks.
