13.  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). 

 

Hi-Gain is Hawking Technologies high performance wireless distance extending product line.    It     

encompasses a group of products and technologies used to help solve distance issues 

accompanied with WiFi products.    A unit of measurement on antenna strength and power is dBi.   

The higher the dBi or gain level of an antenna the more powerful it is. 

 

Directional and omni-directional antennas determine the wireless output pattern of antennas.    In 

standard installations it is normally the wireless access point that uses the omni-directional 

antenna (360 degree wireless output) whiles the clients (desktop or laptops) that use the 

directional antennas (concentrated narrow wireless signal) to create a stronger link directly to the 

access point. 

 

If pointing the antenna directly at the access point is not providing a sufficient signal connection 

then you can try bouncing the signals off walls.    Wireless signals can reflect off walls or through 

windows to get to their desired location so try different positions to find the best antenna orientation 

for your network.    Pair the HWUG1A with the Hawking Hi-Gain Wireless Antenna for extended 

range.
