Abstract
In a wireless network, a cell'"'"'s transmission power and reception sensitivity may be dynamically adjusted along with those of a client device detected in the cell. Thus, in other words, when a client device is in proximity of a particular reader device, the transmission power levels and reception sensitivities of the reader device and the client device may be adjusted in an effort to require the client device to be “drawn in” towards the reader device to conduct a data transaction between the reader device and the client device.
