Abstract:
A system for varying or keeping constant the signal power of all untethered devices not physically connected to a power transmission communication network or all tethered devices electrically connected to a power transmission line communication network, and reassigning a first untethered device according to the positioning or received signal power between the first untethered device and a second tethered device within a first cell and a different tethered device within the first cell or a second cell, the system comprising:a. a first untethered device not physically connected to a power transmission communication network comprising: i. an antenna; ii. a transceiver to send and receive information; iii. a bi-directional coupling means, between said transceiver and said antenna; and iv. a communication protocol; b. a second tethered device electrically connected to a power transmission communication network within a first cell comprising: i. an antenna; ii. a transceiver to send and receive information; iii. a bi-directional coupling means, between said transceiver and said antenna; iv. a power transmission line communication system; v. a bi-directional coupling means, between said transceiver and said power transmission line communication system; and vi. a communication protocol; c. a means for determining positioning or signal power of all untethered devices and tethered devices within wireless range; d. a means for varying or keeping constant the signal power output of all untethered devices in proportion to positioning or received signal power between each untethered device and farthest device within wireless range; e. a means for varying or keeping constant the signal power output of all tethered devices in proportion to positioning or received signal power between each tethered device and farthest device within wireless range to create a new first cell with new wireless radius that may or may not overlap with the second cell; f. a means for evaluating by the second tethered device if the positioning or received signal power of the first untethered electrical device is more optimally connected to the different tethered device; g. a means for communicating through a power transmission line communication network or through wireless communication to the different tethered device to analyze the different tethered device's positioning or received signal power from first untethered device, and capacity to connect to the first untethered device; and h. a means for requesting a handoff through a power transmission line communication network or through wireless communication with the different tethered device such that the different tethered device connects to the first untethered electrical device while the second tethered device disconnects from the first untethered device.
