摘要:
Embodiments of a system and method of determining total isotropic sensitivity (TIS) of a wireless broadband client device are described herein. A received signal strength indicator (RSSI) reported at an embedded radio module of the device is logged for each of a plurality of antenna polarizations and for each of a plurality of platform orientations. A single point measurement of module sensitivity is performed at a reference orientation and polarization the transmit antenna. The TIS is calculated as a correction to the single point measurement of module sensitivity. A correction factor to correct the TIS may be based on the difference between an average of the logged RSSIs and an RSSI at the reference orientation and polarization of the transmit antenna.

摘要:
A method for analyzing service in a wireless communication network, which includes multiple antennas, which are assigned to transmit signals over the air to mobile units on respective sets of one or more frequency channels, such that at least two of the antennas transmit the signals on a common frequency channel. The method includes recording levels of the signals received at multiple locations within a service area of the network, while the antennas are transmitting the signals on the respective sets of frequency channels, including simultaneous transmission by the at least two of the antennas on the common frequency channel. The recorded levels and the frequency channels of the received signals are analyzed so as to classify the received signals at each of the locations according to the antennas transmitting the signals.
摘要:
Various systems and methods for identifying and performing authentication of visible light communications using optical camera communication techniques are described. In an example, an electronic processing system to authenticate a particular light emitting source includes electronic operations for: detecting, from image data, modulated light data emitted from a light emitting object, where the image data depicts the light emitting object, and where the image data is captured with an image sensor (e.g., of a camera); identifying, from the image data, the light emitting object as a source of the modulated light data; receiving an indication to select the light emitting object as an authenticated source of the modulated light data; and performing a command to process the modulated light data from the authenticated source, with the command performed in response to the indication to select the light emitting object as the authenticated source of the modulated light data.
