The number one reason for service degradation
and interruption is radio frequency (RF)
interference.
The following is a list of the top causes
of RF interference:
In-home Wireless LANs (wlans): These inexpensive,
easy-to-setup, and simple to use networks
operate in the same frequencies as NBS's
Wireless Internet Service. There are typically
multiple devices radiating signal well beyond
300 feet. The strong power and close proximity
to our wireless CPE can, and often does,
cause packet loss, slower Internet access,
and even loss of connection
2.4GHz Cordless Phones: These phones often
hop from frequency to frequency throughout
the 2.4GHz band causing slowness, packet
loss, and in extreme cases, loss of connection.
External Wireless LANs (wlans): Many companies
and home owners deploy their networks using
wireless networks operating in the 2.4GHz
and 5GHz bands. the number of Access Points
and clients vary greatly, each radiating
signal far beyond 300 feet. The strong power
and close proximity to our wireless CPE
can, and often does, cause packet loss,
slower Internet access, and loss of connectivity.
Bluetooth Devices: These popular wireless
devices operate in the 2.4GHz band at very
low power. Most devices have an 'effective'
range of 20 to 30 feet, the range at which
they can successfully connect to other devices.
However, their RF will continue to radiate
beyond this 'effective' limit and when in
close proximity to NBS's wireless CPE and/or
in sufficient numbers, can cause slowness,
packet loss, and in extreme cases, loss
of connection.
Microwave Ovens: Many microwave ovens 'leak'
RF in the 2.4GHz range. This can cause slowness,
packet loss, and in extreme cases, loss
of connection.
While neither NBS nor you can control the
use of external wlans, microwave ovens,
and other devices, limiting the use of internal
wlans, Bluetooth devices, and 2.4GHz phones
with NBS's Wireless Internet Service will
reduce the likelihood of interference and
can provide a more stable and robust Wireless Internet experience.
In addition to RF interference, wireless
access can be slowed or even stopped due
to line-of-sight (LOS) issues. Trees, buildings,
and other obstructions can severely hamper
the ability of the wireless network to effectively
communicate. Finally, damaged hardware--cabling,
antenna, and connects--can cause service
interruptions
Here are a few things to keep in mind:
Never cover or place obstructions in front
of the antenna.
Never cut, pierce, or damage the cable
running from the antenna or radio to your
computer.
Never move or attempt to adjust the antenna,
only a NBS certified technician can make
these changes.
Keep trees and shrubs near or below the
antenna trimmed so their branches are at
least two feet below the bottom of the antenna.
If asked to inspect or tighten the wire
connection at the antenna or radio, never
use pliers. Hand tight is sufficient. Over
tightening will cause damage and can cause
service interruptions.
Never move or attempt to adjust the antenna,
only a NBS certified technician can make
these changes.
