Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In telecommunications, the terms multi-band, dual- band, tri-band, quad-band and penta-band refer to a device (especially a mobile phone) supporting multiple frequencies used for communication. In the mobile case, the purpose of doing so is to support roaming between different countries/regions whose infrastructure cannot support mobile services in the same frequency range.
