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 Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique
developed by the military for use in reliable, secure, mission-critical
communication systems. It is designed to trade off bandwidth
efficiency for reliability, integrity, and security. In other words, more
bandwidth is consumed than in the case of narrowband transmission,
but the trade off produces a signal that is, in effect, louder and thus
easier to detect, provided that the receiver knows the parameters of the
spread-spectrum signal being broadcast. If a receiver is not tuned to
the right frequency, a spread –spectrum signal looks like background
noise. There are two main alternatives, Direct Sequence Spread
Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).

What is WPS?
WPS stands for Wi-Fi Protected Setup. It provides a simple way to
establish unencrypted or encrypted connections between wireless
clients and access point automatically. User can press a software or
hardware button to activate WPS function, and WPS-compatible
wireless clients and access point will establish connection by
themselves. There are two types of WPS: PBC (Push-Button
Configuration) and PIN code.
