Location awareness

Source: Wikipedia, the free encyclopedia.

Location awareness refers to devices that can determine their location.

wireless communications
device.

The term applies to

real-time locating, and positioning support with global, regional or local scope. The term has been applied to traffic, logistics, business administration, and leisure applications. Location awareness is supported by navigation systems, positioning systems, and/or locating services
.

Location awareness without the active participation of the device is known as non-cooperative locating or detection.

History of terminology

The term originated for

GNSS
) and radio-equipped mobile devices, the term was redefined to include consumer-focused applications.

While location awareness began as a matter of static user location, the notion was extended to reflect movement. Context models have been proposed[1] to support context-aware applications which use location to tailor interfaces, refine application-relevant data, increase the precision of information retrieval, discover services, make user interaction implicit and build smart environments. For example, a location-aware mobile phone may confirm that it is currently in a building.[2]

Determining location

Description in logical terms uses a structured textual form. International standardisation offers a common method using ISO/TS 16952[3] as originated with German standards DIN EN 61346[4] and DIN EN 81346.[5]

Location in mathematical terms offers coordinates that refer to a nominated point of reference.

Location in network terms relates to locating network nodes. These include:

Variants

"Crisp" locating offers precise coordinates, using wireless signals or optical sighting, possibly[

RFID reader's and RFID tags.[15]

Applications

Location-aware systems address the acquisition of coordinates in a grid (for example using distance metrics and lateration algorithms) or at least distances to reference points (for example discriminating presence at a certain choke point on a corridor or in a room of a building).[16]

GNSS) have become ubiquitous in long-haul transport operation and are becoming a standard automobile feature.[17]

Surveying

Surveying is the static complement to navigating. It is essential for delineating land ownership and for architects and civil engineers designing construction projects. Optical surveying technology preceded laser triangulating aids.[18]

Business process

Currently location awareness is applied to design innovative

process controls, and is integral to ubiquitous and wearable computing. On mobile devices, location aware search can prioritize results that are close to the device. Conversely, the device location can be disclosed to others, at some cost to the bearer's privacy.[19]

Warehouse and routing

RFID provides a time/location reference for an object, but does not indicate that the object remains at that location, which is sufficient for applications that limit access, such as tracking objects entering and leaving a warehouse, or for objects moving on a fixed route, such as charging tolls for crossing a bridge.[20][21]

Consumer

Location awareness enables new applications for ubiquitous computing systems and

self confidence with confirmation of current whereabouts.[22]

Infrastructure

While governments have created global systems for computing locations, independent localized systems exist at scales ranging from one building to sub-national regions.

Local

Such solutions may apply concepts of

wireless personal area network (WPAN), wireless LAN or DECT, with results in proprietary terms of floor plans
or room numbers. Local systems degrade as distance from the locality increases. Applications include the automatic reconfiguration of a computing device to suit the location in which it is currently being used.

Regional

This approach uses for example mobile phone systems, such as

LTE, typically returning information in standardized coordinates as with WGS84 in standardized formats such as National Marine Electronics Association
(NMEA) for outdoor usage or in symbolic coordinates referring to street addresses.

Global

This approach relies on global navigation satellite system (GNSS) technology generally adopting WGS84 and NMEA. Applications include avalanche rescue or emergency and mountain rescue as well as UAVs which are commonly used in search and rescue, (SAR) and combat search and rescue (CSAR).

Network location awareness

Network location awareness (NLA) describes the location of a node in a network.[23][unreliable source?][24]
