M or MM
MAL - Mobile Application Link - an initiative promoted by manufacturers
of data-oriented mobile communications devices and software developers.
Aims to provide uniform/open connectivity for other mobile communications
devices
MAN - Metro Area Network - communications
network, consisting of servers, workstations, network operating
system and a communications link, that generally covers a city
or
suburb.
Mbps - Megabit Per Second - A megabit=1
million bits
MEMS - Micro-Electro-Mechanical Systems
- the integration of mechanical elements, sensors, actuators, and
electronics on a common silicon substrate through the utilization
of microfabrication technology
MEO - Medium Earth Orbit Satellite
- Provides global service, has a 6,000-12,000-mile orbit, is non-geosynchronous
orbit, has a 250
ms round-trip delay, needs a minimum of 20 satellites to cover
the
globe
MIN - Mobile Indentification Number
- uniquely identifies a mobile unit within a wireless carrier's
network - often can be dialed
from
other wireless or wireline networks (differs from the electronic
serial number, which is the unit number assigned by a phone
manufacturer)
MIPS - Million Instructions Per Second
- a general measure of computing performance - for large servers/mainframes
it
is also
a way to measure
the cost of computing, the more MIPS delivered for the money,
the better the value
MLP - Meridian Lossless Packing
MMDS
- Multipoint Multichannel Distribution Service - in 1983 the Commission
reassigned eight channels from the Instructional Television
Fixed Service (ITFS) to MDS. These, eight channels make up the
MMDS - a digital wireless transmission system that works in the
2.2-2.4GHz
range. Frequently, MDS and MMDS channels are used in combination
with ITFS channels to provide video entertainment programming to
subscribers. This service is known as "Wireless Cable"
MMX - a Pentium microprocessor from
Intel that is designed to run faster when playing multimedia applications
MNE - Multinational Enterprise
MOU - Minutes of Use - a measurement
of wireless subscriber activity directly affecting revenue
MPEG - Moving Pictures Expert Group
MPEG-4 - standard set by the International
Telecommunications Union for telephony
MPLS - Multiprotocol Lable Switching
- in an MPLS networking, packets are assigned a label (by a label
edge router) and forwarded along a label switch path where each
(label switch) router makes forwarding decisions based on the contents
of the label. One of the promises of MPLS is the ability to create
end-to-end circuits, with specific performance characteristics,
across any type of transport medium, eliminating the need for overlay
networks or Layer 2 only control mechanisms.
MRAM - Magnetic Random Access Memory
- arrays of magnetic memory cells in which the information is stored as the magnetization
direction of tiny ferromagnetic elements.
MSA - Metropolitan Statistical Area
- the coverage area of a city as in a cellular network (US Census
Burea term)
MS-DOS - Microsoft Disk Operating System
MSO - Multiple System Operator - a major
cable TV organization that has franchises in multiple locations
MSRP - Manufacturers Suggested Retail
Price
MTA - Major Trading Area - MTAs are usually
composed of several contiguous basic trading areas - a service area
designed by Rand McNally and adopted by the FCC. There are 51 MTAs
in the US
MTSO - Mobile Telephone Switching Office
- the electronic middleman between cell sites and the public switched
telephone network, processing traffic back and forth
MVPD - Multichannel
Video Program Distributors - includes DBS (Direct Broadcast Satellite),
Home satellite dishes, wireless cable systems
(using MMDS - Multichannel Multipoint Distribution Service, LMDS
(Local Multipoint Distribution Service), and SMATV (Satellite
Master Antenna Television)
