| Wireless Ethernet uses spread spectrum technology to
transmit data as radio waves, . Spread spectrum spreads the transmission over a broad
frequency range, from 902 thru 928 MHz. Eavesdropping is virtually eliminated because only
the receiving unit is able to un-spread the transmission. The concept for spread spectrum
was created by actress Hedy Lamarr back in 1940. It was put to use in the 1960's for
use in the military and is so effective that it is still in use today. If you have a location that you cannot or do not want to install cabling, then
wireless Ethernet is the solution to your problems. Wireless Ethernet has data throughput
of 2Mbps and can be used for up to 3 miles depending upon the hardware installed (No
FCC License is required).
We've covered security, speed and distance. How about costs? Well, if
you have or are thinking about setting up a a T1 or DDS system, your savings could be
significant. Initial installation costs would be about the same, but recurring yearly
costs would be about $8000 for T1 and about $5000 for DDS. There are NO
recurring costs for wireless Ethernet.
The diagram shows wireless Ethernet bridges connecting networks
between two buildings, however, wireless hubs and wireless network
cards can be used in house to connect between floors. |
