Toward Wide-Area Contactless Wireless Sensing

چکیده
Contactless wireless sensing without attaching a device to the target has achieved promising progress in recent years. However, one severe limitation is small range. This paper presents Widesee realize wide-area with only transceiver pair. utilizes LoRa signal achieve larger range of and further incorporates drone’s mobility broaden area. solutions across software hardware overcome two aspects challenges for wide-range contactless sensing: (i) interference brought by LoRa’s high sensitivity; (ii) ambiguous information such as location when employing just single pair transceivers sensing. We have developed working prototype human detection localization that are especially useful emergency scenarios rescue search, evaluated both controlled experiments field study high-rise building. Extensive demonstrate great potential hosted on drone.

Mobile IP and wide area wireless data
In this paper we present techniques for allowing Mobile IP to interwork with wide area cellular networks. As an example, we illustrate a network consisting of a GSM General Packet Radio Service (GPRS) air interface and a Mobile IP backbone network. The advantage of such a solution is that the backbone network may easily be used to support integrated wireless and wired data transfer, and the lev...

متن کاملWireless Wide Area Networks for School Districts
A wide area network (WAN) is a communications network utilizing devices such as telephone lines, satellite dishes, antennas, and microwaves to span a larger geographic area than can be covered by a local area network (LAN). Typically, a WAN consists of two or more LANs. A metropolitan area network, or MAN, is a term sometimes used to describe a system that falls somewhere between a WAN and LAN ...
