Wireless classroom response system |
摘要 |
<p>A wireless classroom response system wireless network is located proximate to a classroom, a base station that coordinates the activities of the wireless network, and a plurality of handheld units. Each handheld unit is associated with an attendee of a class (either on a long-term or "owned basis, or on an ad-hoc or "shared" basis). Each handheld unit performs a discovery process that includes the steps of randomly choosing a wireless channel, attempting to discover the presence of the wireless network on the channel, and repeating these two steps if no wireless network is discovered.</p> |
