Spread Spectrum Technology (SST)
A method of encoding (with a PN code) a digital signal in a transmitter so as to spread it over a wide range
of frequencies so that the average signal power is close to the noise floor. The same code is known to the
receiver and is used to decode the signal. Keeping the code secret provides communications security.

long as those routers are within line-of-sight of each other.
Subnet mask
This term allows you to mask section(s) (depending on the class specified) of the octets in the network

the remaining nodes.
