331 - SRU109: FDMA and TDMA for beginners

Digital modes, like P25, NXDN, DMR and others will use FDMA, TDMA, or both allow multiple transmissions to share a single frequency at the same time. FDMA or Frequency Division Multiple Access divides a current carrier frequency into multiple parts, allowing for multiple users to operate on the same time on the same frequency. TDMA or Time Division Multiple Access divides a current transmission over time, allowing for 2 or more users to share a the same frequency at the same time, depending on the digital protocol that is used. The ability for these digital transmissions to place multiple users on the same frequency allows for better management of the limited radio spectrum resource. Not only does this allow for more frequencies to be distributed, but allows for end licenses to do more with a single radio license. Learn the differences between FDMA and TDMA in this week's podcast. ==================================== 🛒  Check out our new Merch! ==================================== Squelchy opened his own store selling Scanner School merchandise!
