International Portable Equipment Identity
International Portable Equipment Identity (IPEI) is a unique device number for DECT mobile devices in telephone technology.
The IPEI is assigned to every mobile device by the manufacturer and enables, for example, stolen devices to be blocked. Some DECT base stations require the IPEI to integrate the mobile device into the radio network.
format
The binary IPEI is 36 bits long, of which 16 bits are used as the equipment manufacturer's code (EMC) and 20 bits as the manufacturer's serial number (portable serial number = PSN).
According to ETSI 300 175-6, Annex C, the IPEI should be represented as a decimal number with 13 digits: Manufacturer identification (EMC) five digits, manufacturer serial number (PSN) seven digits and a one-digit check digit. If necessary, EMC and PSN are to be filled in with leading zeros up to the specified number of digits. The spelling is often done with a space between EMC and PSN. The check digit is attached to the PSN without spaces. and determined using the modulo 11 method.
