1. A method of providing communications security, the method comprising:
- (a) generating a protected content stream from a data stream;
(b) transmitting the protected content stream across a first short-range radio communications link; and
(c) transmitting across second short-range radio communications link information for converting the protected content stream into the data stream;
wherein the protected content stream comprises a packet, and wherein step (a) comprises inserting one or more errors into the packet.

Abstract
Generating a protected content stream from a data stream provides enhanced security in short-range wireless communications networks. This protected content stream is transmitted across a first short-range communications link. In addition, information for converting the protected content stream into the data stream is transmitted across a second link. The first link may be an ultra wideband (UWB) link, while the second link may be a Bluetooth link.
