DEVICE COMMUNICATION OVER TELEVISION WHITE SPACE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18457317 titled 'DEVICE COMMUNICATION OVER TELEVISION WHITE SPACE

Simplified Explanation

The patent application describes a multi-narrowband transceiver that enables communication within the television white space (TVWS) frequency spectrum using a log periodic filter. The filter consists of multiple filter elements, each with a filter frequency that increases periodically in the same factor (K). These filters are designed to filter out second harmonics within a specific frequency range. The disclosure determines the appropriate TVWS channel for communication and switches to the corresponding filter element. This allows for narrowband communication over the TVWS channel.

• The patent application describes a multi-narrowband transceiver for communication within the TVWS frequency spectrum.
• The transceiver uses a log periodic filter with multiple filter elements.
• Each filter element has a filter frequency that increases periodically in the same factor (K).
• The filters are designed to filter out second harmonics within a defined frequency range.
• The transceiver determines the TVWS channel for communication and switches to the corresponding filter element.
• Data can be transmitted and received over the TVWS channel using the selected filter element.
• This technology enables narrowband communication over the TVWS channel.

Original Abstract Submitted

The disclosure described herein configures a multi-narrowband transceiver for communication within the television white space (TVWS) frequency spectrum using a log periodic filter, wherein the log periodic filter comprises a plurality of filter elements each having a filter frequency increasing periodically in a same frequency increasing factor (K). Each filter of the plurality of filter elements is configured to filter out second harmonics in a defined frequency range. The disclosure determines a TVWS channel for the communication and switches to a filter element of the plurality of filter elements corresponding to the determined TVWS channel. Data is transmitted and/or received over the TVWS channel using the filter element, thereby allowing narrowband communication over the TVWS channel.
