Frequently Asked Questions
What is DSSS? What is FHSS? And what are their differences?
Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern
that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single
logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence
Spread-Spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is
called a chip (or chipping code). The longer the chip, the greater the probability that the original data can be
recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques
embedded in the radio can recover the original data without the need for retransmission. To an unintended
receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a shared key algorithm, as described in the
IEEE 802.11 standard.
What is WPA?
WPA is Wi-Fi Protected Access, a wireless security protocol that can be used in conjunction with a RADIUS
server.
What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet
networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all
practical purposes, this number is usually permanent. Unlike IP addresses, which can change every time a
computer logs onto the network, the MAC address of a device stays the same, making it a valuable identifier for
the network.
How do I reset the Router?
Press the Reset button on the back panel for about five seconds. This will reset the Router to its default settings.
