Abstract
Official abstract text for this publication.
Embodiments include processes, systems, and devices that allow a white space base station to request available frequency ranges for white space transmission in a local area. A white space finder service models a primary user device's transmission signal propagation area using terrain data associated with the local area of the primary user device. The white space finder service also determines, based on the location of the white space base station and the modeled propagation area, one or more locally available, non-interfering frequency ranges and provides them to the white space base station. The white space base station compares the provided frequency ranges to policies and selects one or more of the available frequencies that accommodate the policies. The white space base station also maps the transmission frequency ranges to virtual frequency ranges for transmission by a software-defined radio employing spectrum virtualization.
First claim
Opening claim text (preview).
What is claimed is: 1. A base station, comprising: a radio transceiver; a spectrum virtualization module configured to exchange physical baseband signals with the radio transceiver, the spectrum virtualization module further configured to perform baseband signal shaping to convert the physical baseband signals into and from virtual baseband signals generated according to one or more virtual frequency bands of a wireless transmission protocol of the spectrum virtualization module…
