PMR446 (Europe) - analog and digital license-free low power radio service, similar to FRS in the United States and UHF CB in Australia and New Zealand. Harmonized throughout Europe and the UK. 500mW power limit. Originally assigned 8 channels, then expanded to 16 analog/digital channels + 32 digital only voice/data channels in the 446.0 to 446.2 MHz range. In Europe this frequency spectrum is not part of the 70cm amateur band.
