Narrowbanding was mandated in the 1990's and it was pretty much everyone's belief that by requiring the manufacture of narrowband capable VHF/UHF 450-512 MHz radios that there would be little financial impact on licensees when the time finally came to make the switch. There have been a couple of extensions of the date (this is just the first phase to 12.5 kHz). Now the cutover date is approaching and there are more licensees than imagined who haven't planned or budgeted for the change of the fixed infrastructure. In fact, quite a few of the old radios are still in use that can't make the switch - like the widely used old Motorola upright high power Micor base stations.
There is some degradation in coverage when reducing the bandwidth (somewhere around 3 dB according to TIA TSB-88), so the cut is not entirely painless. Some large agencies like NYPD are resisting the change and cite their desire to transition to broadband. Local government budgets are tight and this is now viewed by some as an unfunded mandate. The FCC doesn't want to extend the deadline again - they need to accommodate more users in the available spectrum. There's a shortage, remember? So, you thought the DTV cutover was painful?
