Security
The Wireless Link's built-in security feature automatically
selects one of over 260,000 digital security codes for
the base and remote unit. Each base and remote unit operate
as pair and securely communicate with one another using
Nebo's Lock-In™ technology. If you own
more than one Wireless Link, please remember that matched
base and remote units must be used together.
Patent-protected Lock-InTM Technology
Nebo's patent-protected Lock-In™ technology
provides inherent security as a side benefit of conditioning
the dialup wireless communication channel.
During establishment of a conventional, wired dialup
connection, two parties (Call them the modem and the
ISP.) automatically negotiate the highest possible connection
speed. It's necessary to negotiate for every 'phone connection
because each one differs in levels of signals and noise,
and in ability to carry the signal. The negotiation process
makes that odd but familiar noise you hear as your modem
and the ISP attempt to communicate.
Since it takes advantage of the modem already built into
your PC, the Wireless Link's radio must transfer the
bi-directional modem signal unaltered. Its built-in microprocessor
solves this problem with an enhanced negotiation among
your modem, the radio link and ISP. The microprocessor
searches among thousands of possible gain setting, offset
and equalization combinations to find the optimum mapping
between the 'phone and microwave segments of the connection.
Unlike Wi-Fi , the Wireless Link's optimized mapping during the handshake process requires "seeing" the line condition between the 'phone and microwave segments of the connection. A snooper will not be able to duplicate this line condition unless he can "see" your 'phone wire (and in that case he can capture your data directly). It is technically
impossible to infer the telephone line's condition later,
because the microwave signal in the air is already "conditioned" by
the microprocessor.
Thus the "packet sniffing" and theft-of-service problems
plaguing 802.11 WiFi data communications are eliminated
by the Wireless Link Lock-In™ technology. There is no need to encrypt data
passing across it.
