Intranet
An intranet is a private computer network that uses Internet protocols, network connectivity, and possibly the public telecommunication system to securely share part of an organization's information or operations with its employees. Sometimes the term refers only to the most visible service, the internal website. The same concepts and technologies of the Internet such as clients and servers running on the Internet protocol suite are used to build an intranet. HTTP and other Internet protocols are commonly used as well, especially FTP and e-mail. There is often an attempt to use Internet technologies to provide new interfaces with corporate 'legacy' data and information systems.
Briefly, an intranet can be understood as "a private version of the Internet", or as a version of the internet confined to an organization.
IMEI - International Mobile Equipment Identity
The International Mobile Equipment Identity (IMEI) is a number unique to every GSM and UMTS mobile phone. It is usually found printed on the phone underneath the battery and can also be found by dialing the sequence *#06# into the phone.
The IMEI number is used by the GSM network to identify valid devices and therefore can be used to stop a stolen phone from accessing the network. For example, if a mobile phone is stolen, the owner can call his or her network provider and instruct them to "ban" the phone using its IMEI number. This renders the phone useless, regardless of whether the phone's SIM is changed.
I-mode:

Lithium Ion battery:
a type of rechargeable battery for cell phones which is generally lighter weight than earlier battery types, has a relatively longer cycle life, and generally does not suffer from “memory” effect.
Lithium Polymerbattery:
a battery technology similar to lithium ion but allows the battery to be molded to any shape allowing greater flexibility for mobile phone designers.

Modulation:
The process of imposing an information signal on a carrier. This can be done by changing the amplitude (AM), the frequency (FM) or the phase, or any combination of these
MPEG:
Motion Picture Experts Group; MPEG4 is a technology for compressing voice and video so that the information can be transmitted over normally difficult links such as mobile radio

MMS - Multimedia Messaging Service
(a further extension of SMS and EMS.MMS is designed to make use of newer and quicker mobile transmission methods such as GPRS, HSCSD, EDGE and UMTS, involving the attachment of multimedia extensions to messages, such as video and sound. An e-mail function is also planned. )
MO-SMS - Mobile-Originated Short Message Service
(the ability to send short text messages from a phone. Both the phone and the carrier’s network must support this feature for it to work. Messages can be sent to other phones by phone number. Many phones also allow sending messages directly to e-mail addresses
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.
