Robust Radio
Operation
MDS entraNET transceivers use an advanced Media Access Controller
(MAC) to ensure network access for stations with data to send. The
MAC permits data to be sent from endpoint devices on an on-demand
basis, preventing over-the-air data collisions and ensuring that data gets
through as intended. MAC functionality eliminates the need for active
polling of Remotes, an important requirement in Report-by-Exception
(RBE) applications.
Rugged Packaging MDS entraNET radios are housed in compact and rugged die-cast cases
that need only be protected from direct exposure to the weather. The
transceivers are supplied with flat surface-mounting brackets or optional
35 mm DIN rail brackets, depending on customer requirements.
Simple Installation Basic installation typically employs an omni-directional antenna at the
AP site and a directional antenna at each
associated Remote site. The
antenna is a vital link in the system and must be chosen and installed
correctly.
INSTALLATION PLANNING on Page 149 provides guidance
on choosing proper antennas and installation sites.
To establish basic service, connect an antenna, connect an Ethernet LAN
(Local Area Network) to the AP, connect a serial or Ethernet device to
the Remotes, apply power, set a few operating parameters using a
personal computer, and you are done. No license is required for
operation in the U.S.A., Canada, and many other countries. Check the
regulations in your country before placing the radios on the air.
GE MDS Security
Suite
Network security is a vital issue in today’s wireless world. The
MDS entraNET system provides multiple tools to help you build a
network that minimizes the risk of eavesdropping or unauthorized
access. Some security features are inherent to radio operation, such as
the use of spread-spectrum transmission. Other techniques are built into
