Problems solved by technology

If two radios are too close to each other, even though the radios operate on different channels in the same frequency band, when one radio (the first radio) transmits, the transmission (TX) from the first radio Power may completely overwhelm the receive (RX) capability of another radio (second radio), resulting in invalid measurements

Embodiment Construction

[0018] This description provides examples which are not intended to limit the scope of the appended claims. The drawings generally indicate features of the examples, wherein it should be understood and appreciated that like reference numerals are used to refer to like elements. Reference in the description to "one embodiment" or "an embodiment" or "example embodiment" means that a particular feature, structure, or characteristic described is included in at least one embodiment described herein and does not It is implied that the feature, structure, or characteristic is present in all embodiments described herein.

[0019] In an example embodiment, signaling is employed between two radios (eg, a first radio and a second radio) that enables the radios to determine when the other radio is transmitting. For example, a signal that may allow the second radio to determine when the first radio is transmitting may be transmitted by the first (transmitting) radio to the second (receivi...

Abstract

In example embodiments disclosed herein, a multi-radio device is described that includes a first radio including a transmitter and a second radio including a receiver, the multi-radio device including a first radio and a second radio. The receiver monitors the channel for data representing predefined channel parameters. The second radio is operable to receive a signal from the first radio indicating when the transmitter of the first radio is transmitting. Based on whether the transmitter of the first radio is transmitting, the receiver of the second radio selectively excludes data representative of the predefined channel parameters.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application No. 13 / 943,425, filed July 16, 2013. technical field [0003] The present disclosure generally relates to Interactive Voice Response (IVR). Background technique [0004] RF monitoring is useful for determining channel conditions. Metrics of interest may include, but are not limited to: channel noise (e.g., noise floor level), CCA (clear channel assessment, e.g., channel busyness), and WIFI packet metrics (e.g., packet error rate (PER) and / or bit error rate (BER)). Channel metrics can be input into various algorithms that optimize the operating channel and / or power of the access point. If two radios are too close to each other, even though the radios operate on different channels in the same frequency band, when one radio (the first radio) transmits, the transmission (TX) from the first radio The power may completely overwhelm the receive (RX) capability of the oth...
