N-AMPS
Narrowband AMPS
NAM (Number Assignment Module) a circuit chip located inside a phone which stores your telephone number, lock code, timer reset code, network information and other operational data. The NAM is programmed by the service provider when a device is activated. Today’s phones have EPROM type NAM and are keypad programmable.
NAMPS (Narrowband Advanced Mobile Phone Service) is the next generation of AMPS systems. NAMPS is a cellular call-handling system that uses digital signaling techniques to split the existing channels into three narrowband channels. The result is three times more voice channel capacity than the traditional AMPS system provides.
NB
Normal Burst; used to carry traffic and control channels except RACH
NCC (National Color Code or Network Color Code
NET
Norme Europeenne de Telecommunications
NiMH - Nickel Metal Hydride
NMSI - National Mobile Subscriber Identity
NMT: - Nordic Mobile Telephone system
(an analogue cellular technology deployed in the Nordic countries in the late 1970’s; variations were also deployed in the Benelux countries and in Russia. NMT operated in the 450 and 900MHz bands and was the first technology to offer international roaming, albeit only in the Nordic countries)
Node B:
The element in a UMTS network which interfaces with the mobile station, analogous to a BTS in a GSM network
No Service:
An indication on the display of a cellular phone that indicates that the user is in an area where cellular service is unavailable
