Personal communications network
Personal communications network is the European digital cellular mobile telephone network. The underlying standard is known as Digital Cellular System, which defines a variant of GSM operating at 1.7–1.88 GHz. GSM-1800 has since been adopted by other locations, not necessarily under the PCN/DCS name. The network structure, the signal structure and the transmission characteristics are similar between PCN and GSM-900.
The PCN system was first initiated by David Young, [Baron Young of Graffham|Lord Young], UK Secretary of State for Trade and Industry, in 1988. The main characteristics of PCN are as follows:
- Operating frequency – 1.7–1.88 GHz.
- Uses 30 GHz or up for microwave back bone system.
- Covers both small cells and large cells.
- Coverage inside and outside buildings.
- Hand over.
- Cell delivery.
- Portable hand set.
- User intelligent network.
PCN is comparable to the North American Personal Communications Service band allocation. The 1800 MHz DCS band is reused in UMTS, LTE and 5G NR; it sees real-world deployment in LTE as "band 3".
