Problems solved by technology

For example, the communication channels and propagation characteristics of 60GHz signals will be very different. At least one reason is that the 60GHz radiation will be partially absorbed by the oxygen in the air, which will cause the signal to be attenuated with the transmission distance

Embodiment Construction

[0037] Some embodiments of the present invention relate to methods and systems for detecting and / or tracking entities using extremely high frequency repeaters and / or transceivers. The multiple repeaters use an extremely high frequency (EHF) interface to detect and / or track entities located in the area of ​​the multiple repeaters. Each repeater will transmit an EHF signal to realize the identification of the transmitter repeater. The identification of the transmitter repeater includes the use of unique information and / or transmission parameters. Each repeater determines the characteristics of the received EHF signal to determine the existence and / or location of entities located in the area of ​​the plurality of repeaters. The above characteristics include: the identity of the transmitter repeater, signal power, signal amplitude, signal delay, and / or reception angle. In addition, non-EHF connections may be used between the multiple repeaters to coordinate and / or update the dete...

Abstract

The present invention relates to a method and system for multiple repeaters to detect and / or track entities within range of the repeaters using an extremely high frequency (EHF) interface. Each repeater emits an extremely high frequency signal that can identify the transmitting repeater. The above-mentioned identification of the transmitting EHF repeater is realized through characteristic information and / or transmission parameters. Each repeater determines information characteristic of received EHF signals to enable determination of the presence and / or location of entities within range of the repeater. The aforementioned feature information may include: transmitting repeater identity, signal power, signal amplitude, signal delay, and / or receiving angle. Non-extremely high frequency (non-EHF) connections within range of the repeaters may be used to coordinate and / or update detection and / or tracking procedures of entities located within range.

Description

Technical field [0001] The present invention relates to wireless communication, and more specifically, to a method and system for detecting and / or tracking entities using extremely high frequency repeaters and / or transceivers. Background technique [0002] In 2001, the Federal Communications Commission (FCC) designated the continuously adjacent 7GHz bandwidth in the 57GHz to 64GHz spectrum for communication. The use of this frequency band is license-free (no need to obtain a license issued by the FCC), that is to say, anyone can use this spectrum under the basic technical limitations such as maximum transmission power and coexistence mechanism. Communication in this frequency band is usually called "60GHz communication". As far as the accessibility of the designated part of the frequency band is concerned, 60GHz communication is similar to other forms of unlicensed spectrum usage, such as wireless local area network (WLAN) or Bluetooth communication in the 2.4GHz ISM frequency b...
