Until the repack is complete, however, things are still murky. There are already some great resources that illustrate the final post-repack layout of the VHF and UHF bands available-for instance, Radio Active Designs has a very easy to navigate tool here that covers many different markets. This phase schedule is the basis for the Repack Timeline Overview chart featured below.
Conversely, the Dallas market (among others) will transform during just one phase, over the course of two months. In some markets, like Boston, the repack will be gradual, spanning multiple phases and almost nine months. This ‘dance’ is scheduled by the FCC across ten phases (pictured below), ranging from one to four months each. Maps showing two ‘linked station sets.’ Compiled from FCC Phase Assignment Tableau File These dependencies are referred to as ‘linked station sets’-the largest of which consists of 94 stations across the Mid-Atlantic and Southeastern US, followed closely by another set of 89 stations in the Northeast and Canada. Because many stations are moving to RF channels that are currently occupied by other stations, these moves must be made in a coordinated fashion to minimize interference between transmitters. The repack process is like a dance, choreographed by the FCC in conjunction with broadcasters. What should we expect between now and July 2020? Some are wondering if these purchases can be delayed or spread out over the next eighteen months, and the answer is not simple. For many companies and organizations, losing the 600 MHz band means a significant number of wireless systems must be replaced. Displaced stations are either going dark or moving to lower frequency bands, making an already-crowded RF spectrum even tougher to navigate for users of wireless microphones, IEM, and communications systems. Television stations will cease broadcasting in the 600 MHz band, and cell phone companies will begin using that space.
