First Claim
1. A method, comprising:
- in a first wireless communication device;
receiving a first wireless signal from a second wireless communication device;
estimating a relative distance to the second wireless communication device according to a power level of the first wireless signal;
transmitting different levels of security information to the second wireless communication device according to the relative distance;
establishing an ad-hoc communication link with the second wireless communication device; and
sharing a replica of at least a portion of a display of the first wireless communication device with the second wireless communication device utilizing a second wireless signal that is communicated via the established ad-hoc communication link, wherein;
said first wireless communication device is operable to communicate the second wireless signal at a power level that is below a spurious emissions mask; and
the second wireless signal is a broadband signal in a designated frequency spectrum band.

Abstract
A wireless communication device (WCD) establishes an ad-hoc communication link with a second WCD within operating range. A replica of at least a portion of a display of the first WCD may be shared with the second WCD utilizing wireless broadband signals that are communicated via the established one or more ad-hoc communication links. The first WCD and the second WCD are operable to communicate the wireless broadband signals at a power level that is below a spurious emissions mask. The transmitted wireless broadband signals are spread so they occupy a designated frequency spectrum band. The shared replica of at least a portion of the display of the first WCD includes one or more applications, text, video and/or data content. A user of the first WCD may interact with content that is displayed on a display of the second WCD and vice-versa.
