![]() ![]() RF environments post auction will require us all to rethink the way we use and operate wireless systems. GB (guard band) DG (duplex gap) L/M (licensed) UL/M (unlicensed) This is what is referred to as the 600 MHz duplex gap. The gap between the two spectrum ranges is still open for licensed (653 – 657 MHz) and non-licensed (657 – 663 MHz) wireless microphone transmissions. Download links, in which data from the cell towers is sent to the end user’s device, will occur at 617 – 652 MHz. The cell phone upload links, wherein data from the end user’s phone is sent to cell towers, will occur at 663 – 698 MHz. The two groups of frequencies will be mostly used for cellular data upload and download links for new networks. This means that if your current wireless system even has the ability to transmit on these frequencies, you will need to stop using it by summer 2020. You may note that the FCC deems a particular system unusable if it has the “potential” to operate in the auctioned spectrum, which was 617 – 652 MHz and 663 – 698 MHz. A few weeks back, we discussed which wireless systems you may use to replace your equipment that will soon be deemed illegal to operate in the United States. Question: What is the 600 MHz Duplex Gap?Īnswer: With the FCC auction of the 600 MHz spectrum, a lot of wireless microphone users are looking at what options they have to move forward. ![]()
