Co-Location for
Multiple Networks
It may be desirable to co-locate Access Points at one location to take
advantage of an excellent or premium location that can serve two inde-
pendent networks. Each network should have unique Network Name
and each AP unit’s antenna should be provided as much vertical separa-
tion as is practical to minimize RFI.
NOTE: All radios are shipped with the Network Name as
“Not Programmed.” The Network Name must be programmed
in order to pass data and begin normal operations.
Can radio-frequency interference (RFI) disrupt my Network?
When multiple MDS entraNET 900 networks operate in close physical
proximity to other wireless networks, individual units may not operate
reliably under weak signal conditions and may be influenced by strong
radio signals in adjacent bands. This radio frequency interference cannot
be predicted and can only be determined by experimentation. If you
need to co-locate two transceivers, start by using the largest possible
vertical antenna separation between the two AP antennas on the same
support structure. If that does not work, consult with MDS technical
support personnel about other techniques for controlling radio fre-
quency interference between the radios. (
See “A Word About Radio
Interference” on Page 108 for more details.)
1.4 SECURITY TECHNIQUES & TOOLS
Today the operation and management of an enterprise is becoming
increasing dependent on electronic information flow. An accompanying
concern becomes the security of the communication infrastructure and
the security of the data itself.
The MDS entraNET 900 is capable of dealing with many common secu-
rity issues.
Table 1-2 profiles security risks and how the MDS entraNET
900 provides a solution for minimizing vulnerability.
Table 1-2. Security Risk Management
Security Risk The MDS entraNET 900 Solution
Unauthorized access to the backbone
network through a foreign remote radio
√
Approved Remotes List
Only those remotes included in the
AP list will associate
“Rogue” AP, where a foreign AP takes
control of some or all remote radios and
thus remote devices
√
Approved AP List
A remote will only associate to
those AP included in its local
authorized list of AP
Dictionary attacks, where a hacker runs a
program that sequentially tries to break a
password.
√
Failed-login lockdown
After 3 tries, a transceiver ignores
login requests for 5 minutes.
Critical event reports (traps) are
generated as well.
