A translating bi-directional packet repeater includes a first antenna and a second antenna for receiving a wireless signal, amplifying it, and retransmitting it on a different channel. The channel associated with each of the antennas is separated in frequency sufficiently to ensure good isolation between the wireless signals that are received and then retransmitted. The wireless signal is down converted to an intermediate frequency (IF) that is passed through a band pass filter, and the filtered signal is then up converted and retransmitted on the different channel. A controller responds to a wireless signal on one of the antennas in selecting a path through the bi-directional amplifier and the antennas used to receive and retransmit the signal. The isolation between the received wireless signal and the retransmitted wireless signal is sufficient to avoid interference, and the retransmission takes place almost instantaneously to minimize the delay incurred.

Local area network translating bi-directional packet repeater

A system and method in a wireless network for discovering which resources (e.g., other wireless computing devices) are proximate a user's wireless computing device. Wireless signal strengths with respect to various base stations are compared with the signal strengths of other network devices or resources, to determine which devices are experiencing similar signal strengths. Devices with similar signal strengths are deemed proximate. Each participating computing device may send its signal strength reports to a proximity server, which distributes proximity data to network clients. Each client may receive and process the signal strength data for determining which other clients/resources are proximate, or the server can perform proximity computations and return a list of proximate clients. Once computed, the identities of the proximate clients can be used to query for additional data about the clients, such as the names and other details of their owners, or information about the resource.
