A method for dynamically reconfiguring a regulation-compliance mode of a device, belonging to a wireless network and operating under a network-operation mode (311, 321, 322) in a spectrum band with primary users. The method includes periodically determining at least one of: a primary protection capability of the device (501, 502, 704, 705), availability of enabling signal to the device (601, 701), and a frequency of location change of the device (508, 510, 711, 712); and based on the results of such determinations, operating and configuring transmission parameters of the device according to one of a plurality of regulation-compliance modes that are supported by the device. The wireless device includes: a signal transceiver (201) for processing, transmitting and receiving wireless signals from secondary devices; a primary signal sensing module (202) for detecting a primary signal; a spectrum manager (204) for selecting or deselecting an operating frequency channel; and a geolocation module for determining the location of the device. The wireless device may further include a network interface (203) for accessing a TV band database and a geolocation database.
