BreezeMAX PRO 5000 CPE
Multipoint Communications Systems. Applications licensed at 2500 MHz in Canada. A
wide variety of applications are possible including one-way and two-way transmission
and a diversity of distribution capacities.
Multichannel Multipoint Distribution Service. MMDS is a licensed wireless service that
has the capability to provide broadband access. MMDS operates in several parts of the
2 GHz spectrum.
Microsoft Challenge Handshake Authentication Protocol. an implementation of the
CHAP protocol that Microsoft created to authenticate remote Windows workstations. In
most respects, MS-CHAP is identical to CHAP, but there are a few differences.
MS-CHAP is based on the encryption and hashing algorithms used by Windows
networks, and the MS-CHAP response to a challenge is in a format optimized for
compatibility with Windows operating systems.
Maximum Segment Size.
Not Available or Not Applicable
Network Entry
Network Interface Card. An expansion board you insert into a computer (or a built-in
component) that enables the computer to connect to a network. Most NICs are
designed for a particular type of network, protocol, and media, although some can
serve multiple networks.
Outdoor Unit
Orthogonal Frequency Division Multiplexing: A method for multiplexing signals, which
divides the available bandwidth into a series of frequencies known as tones.
Orthogonal tones do not interfere with each other when the peak of one tone
corresponds with the null. The rapid switching, frequency-hopping technique is
intended to allow more robust data service.
Orthogonal Frequency Division Multiple Access. It's a logical extension of OFDM and a
modulation/multiple access technique. OFDMA divides a signal into sub-channels (i.e.
groups of carriers), with each sub-channel (or several sub-channels) being allocated to
a different subscriber.
Packet Error Rate. In a digital transmission, PER is the percentage of packets with
errors divided by the total number of packets that have been transmitted, received or
processed over a given time period.
PHYsical Layer. The physical, or lowest, layer of the OSI Network Model. In a wireless
network, the PHY defines parameters such as data rates, modulation method, signaling
parameters, transmitter/receiver synchronization, etc. Within an actual radio
implementation, the PHY corresponds to the radio front end and baseband signal
processing sections.
