MDN Mobile Directory Number. The directory listing telephone number
that is dialed (generally using POTS) to reach a mobile unit. The
MDN is usually associated with a MIN in a cellular telephone -- in
the US and Canada, the MDN and MIN are the same value for voice
cellular users. International roaming considerations often result in
the MDN being different from the MIN.
MIL 1 mil = 1 thousandth of an inch.
MIN Mobile Identification Number. The unique account number
associated with a cellular device. It is broadcast by the cellular
device when accessing the cellular system.
Misread (Misdecode) A condition which occurs when the data output of a reader or
interface controller does not agree with the data encoded within a

Mobile Computer In this text, mobile computer refers to the Symbol Series 9000
wireless portable computer. It can be set up to run as a stand-
alone device, or it can be set up to communicate with a network,
using wireless radio technology.
NCU Network Control Unit.
NetBeui A non-routable LAN protocol that is an extension to NetBIOS. Used
for IBM’s OS/2-based LAN Manager and Microsoft’s LAN Manager
and Windows for Workgroups.
NetID For mobile computers using Spectrum24 radios with the Spring
protocol, a NetID allows facilities to limit which Access Points a
mobile computer can communicate with. It is set on the Network
tab of the Control Panel. The mobile computer can only
communicate with Spectrum24 Access Points that have matching
NetIDs. Also see ESS_ID.
Nominal The exact (or ideal) intended value for a specified parameter.
Tolerances are specified as positive and negative deviations from
this value.
Nominal Size Standard size for a bar code symbol. Most UPC/EAN codes are used
over a range of magnifications (e.g., from 0.80 to 2.00 of nominal).
NVM Non-Volatile Memory.
ODI See Open Data-Link Interface.
Open Data-Link Interface (ODI) Novell’s driver specification for an interface between network
hardware and higher-level protocols. It supports multiple protocols
on a single NIC (Network Interface Controller). It is capable of
understanding and translating any network information or request
sent by any other ODI-compatible protocol into something a
NetWare client can understand and process.
Open System Authentication Open System authentication is a null authentication algorithm.
PAN
Personal area network. Using Bluetooth wireless technology, PANs
enable devices to communicate wirelessly. Generally, a wireless
PAN consists of a dynamic group of less than 255 devices that
communicate within about a 33-foot range. Only devices within this
limited area typically participate in the network.
Parameter A variable that can have different values assigned to it.
