System and method for deterministic testing of packet error rate in electronic devices

Abstract

A method and system for testing packet error rate in electronic devices by transmitting a series of data packets from a testing device to a device under test (DUT) and setting a predefined number of received error-free data packets; evaluating whether a number of data packets from the series of data packets received error-free by the DUT equals the predefined number of received error-free data packets and transmitting additional data packets from the testing device to the DUT, at a power level known to produce zero received-packet errors in a correctly operating DUT, if the number of data packets from the series of data packets received error-free by the DUT does not equal the predefined number of received error-free data packets. Additional possible embodiments include evaluating whether a total number of data packets from the series of data packets and the additional error-free-power-level data packets received error-free by the DUT equals the predefined number of received error-free data packets and transmitting a confirmation data packet to the testing device in response to reception by the DUT of the predefined number of received error-free data packets.

Description

technical field [0001] The present invention generally relates to systems and methods for testing electronic devices. More specifically, the present invention relates to improvements in systems and methods for testing wireless devices using a test platform consisting of hardware, firmware and / or software components such that a minimum of feedback. Background technique [0002] Many of today's handheld devices use "wireless connectivity" for telephony, digital data transfer, geolocation, and more. Despite differences in spectrum range, modulation method, and power spectral density, wireless connectivity standards transmit and receive data in isochronous packets. Typically, all of these wireless connectivity capabilities (such as WiFi, WiMAX, Bluetooth, etc.) are defined by industry-accepted standards (such as IEEE 802.11 and IEEE 802.16), which specify the parameters and limitations that devices with the above connectivity capabilities must adhere to .

AI Technical Summary

Problems solved by technology

Other protocols, such as Bluetooth LE, will require additional time slots for sending such acknowledgment (ACK) information, i.e. packets that will essentially double the test time in some cases

A common challenge provided by conventional test methods is the use of sequences that do not contribute direct test values
