IS-95. Interim Standard 95. The EIA/TIA standar d that governs the operation of CDMA cellular service. Versions include
IS-95A and IS-95B. See CDMA.

K

Key. A key is the specific code used by the algorithm to encrypt or decrypt the d ata. Also see, Encryption and
Decrypting.

L

LASER. Light Amplification by Stimulated Emission of Radiation.The laser is an intense light source. Light from a laser
is all the same frequency, unlike the output of an incande scent bulb. Laser light is typically coher ent and has a high
energy density.
Laser Diode. A gallium-arsenide semiconductor type of laser connected to a power source to generate a laser beam.
This laser type is a compact source of coherent light.
laser scanner. A type of bar code reader that uses a beam of laser light.
LCD. See Liquid Crystal Display.
LED Indicator. A semiconductor di ode (L ED - Ligh t Emitting Dio de ) us ed as an in dicator, ofte n in di gital displays. Th e
semiconductor uses applied voltage to produce light of a certain frequency determined by the semiconductor's
particular chemical composition.
Light Emitting Diode. See LED.
Liquid Crystal Display (LCD). A display that uses liquid crystal sealed between two glass plates. The crystals are
excited by precise electrical charges, causing them to reflect light outside according to their bias. They use little
electricity and react relatively quickly. They require external light to reflect their information to the user.

M

MC. Mobile Computer.
MDN. Mobile Direct ory Num b er . The dir ec tor y listing telephon e nu m be r th at is dia led (ge ner ally using POTS) to reac h
a mobile unit. The MDN is usually associated with a MIN in a cellu lar telepho ne -- in the US and Canad a, the MDN
and MIN are the same value for voice cellular users. International roaming considerations often result in the MDN
being differen t fr om the MIN.
MIL. 1 mil = 1 thousandth of an inch.
MIN. Mobile Identification Number . The unique accoun t number associated with a cellular d evice. It is broadcast by the
cellular device when accessing the cellular system.
