Location technology definitions from wikipedia

Location Technology Definitions (from Wikipedia)

  • Radio-frequency identification (RFID)

    “Radio-frequency identification (RFID) is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.”

  • Real Time Locating Systems (RTLS)

    “Real Time Locating Systems (RTLS), are used to track and identify the location of objects in real time using simple, inexpensive nodes (badges/tags) attached to or embedded in objects and devices (readers) that receive the wireless signals from these tags to determine their locations. RTLS typically refers to systems that provide passive (automatic) collection of location information.”

  • RFID Tags

    “Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal. There are generally two types of RFID tags: active RFID tags, which contain a battery and thus can transmit its signal autonomously, and passive RFID tags, which have no battery and require an external source to initiate signal transmission.”

Technologies granularities

Technologies & Granularities

  • Almost any RF technology can be used to provide location

    • Early Navigation systems (e.g. LORAN) used Low Frequency RF (LF), modern system (e.g. GPS) use Ultra High Frequencies (UHF)

    • Wireless WAN/LAN/PAN systems can also be used to provide location

    • Many short-range proprietary LF, HF and UHF systems are available

Wlan location methods

WLAN Location Methods

  • Connection AP & RSSI (e.g. RingMaster)

    • Known AP location and client RSSI value gives a distance approximation

      • Client is somewhere on the RSSI contour

      • RF obstacles modify the RSSI contour

      • An assumption must be made about the client’s TX power

    • Presence solution only, poor location accuracy

  • Trilateration (e.g. RingMaster)

    • Known AP locations plus client RSSI value from 3 or more APs gives an accurate, unique location

      • RF obstacles modify the distance estimations

      • An assumption must be made about the client’s TX power

    • Factors affecting the solution quality:

      • The number of APs seeing the client signal

      • The geometry of the APs

      • The quality of the RF model for the floor plan

Trapeze Networks, A BELDEN Brand | Proprietary and Confidential | 8/14/2014 Slide 10


Wlan location methods1

WLAN Location Methods

  • Server-side Pattern Matching (LA-200)

    • A patented method for matching a client to a known location

    • The pattern of client RSSI seen by multiple APs in a location creates a distinct ‘fingerprint’

    • A client that matches the same RSSI pattern is probably at the same location

      • Client TX power is simply not relevant

      • No RF model for the floor plan is required

      • No need to define RF obstacles

WLAN Location Methods

  • Server-side Pattern Matching

    • The LA-200 uses patented technology to track client device location

      • Location APs continuously report back RSSI data to the LA-200

      • The LA-200 assembles and organizes this data by MAC address and forms a sample

      • The sample is compared to the available RF Fingerprints in the database to find the best match

      • Trilateration is used when possible for XY coordinates

Wlan location methods3

WLAN Location Methods

  • Server-side Pattern Matching Advantages

    • RF degradations become location differentiators

      • Multipath, reflection and occlusions become part of the Fingerprint

      • Statistical model smoothes out noise

    • Location reliability

      • Location Tracking can be done in real-time and in 3 dimensions

      • Locate a device wherever it is within the coverage area

      • Excellent discrimination of room/area boundaries

      • Resolve locations to named areas or XY coordinates

    • Employs the existing WLAN infrastructure

      • Already approved for use in many environments (e.g. healthcare)

      • WLAN tracking works indoors (unlike GPS)

      • Location information may be delivered directly over the existing data network for use by Location aware applications

  • Server-side Pattern Matching, what it is NOT

    • Triangulation/Trilateration: RF degradations downgrade accuracy

    • Time Difference of Arrival (TDOA): requires precise timing synchronization

    • Client-side software: extremely difficult to deploy and manage

Lbs technology comparison

LBS Technology Comparison

  • Trapeze vs. the Cisco Location Appliance

    • Trapeze is more accurate: average 3-5m precision vs. 5-10m for Cisco

    • Trapeze is faster: 15 sec shortest latency vs. 60 sec for Cisco

    • Trapeze needs no extra HW: The Trapeze solution requires APs and the Appliance only vs. Cisco who need exciters/chokepoints to make up for location tracking deficiencies

    • Trapeze gives lower TCO: The Trapeze solution leverages the existing APs vs. the Cisco approach which requires a costly overlay of exciters/chokepoints

      Note: Aruba has no dedicated location solution

  • Competing LBS Vendors

    • Aeroscout: TDOA and a hybrid Active RFID with a proprietary (and expensive) 125KHz chokepoint solution

      • The Wi-Fi infrastructure is used to backhaul telemetry data

      • Basic RSSI Trilateration but rely on Cisco for Wi-Fi position

    • Ekahau: Client-side RSSI Fingerprints a technology that requires Ekahau client software on the devices to be tracked

      • Complex calibration that becomes invalid on a change in channel/transmit power of the APs

Lbs definitions

LBS Definitions

  • Location AP

    • A ‘Location AP’ is an Access Point operating in snoop mode sending data to the LA-200 defined as the ‘Observer’

      • Types: dedicated or dual-purpose (service providing)

  • Locale

    • A ‘Locale’ is a discrete space within the building environs of any convenient size that it is necessary to track mobile devices to

      • Naming Convention: a naming convention appropriate to the customer site is recommended, e.g. Parking lot, Hanger, Office-1, Lobby

  • RF Fingerprint

    • An ‘RF Fingerprint’ is a specific point within a ‘Locale’ where an RSSI pattern has been captured during the ‘Calibration’ process

      • Density: there MUST be at least 1 RF Fingerprint per Locale, there MAY be multiple RF Fingerprints per Locale

      • Plan for around 4 Fingerprints per Location AP

  • Calibration

    • ‘Calibration’ is the process by which the LA-200 captures RF signature data for ‘RF Fingerprints’ within each ‘Locale’

Trapeze Networks, A BELDEN Brand | Proprietary and Confidential | 8/14/2014 Slide 26

Map the lbs space

Map the LBS Space

  • Knowledge of the physical environment is essential

    • Obtain or create floor plans

    • Ensure the scale of the plans is accurately known

      Note: the LA-200 Dashboard requires a .jpg, .png or .gif version of the floor plan e.g. the RingMaster floor plan exported via a Work Order

  • Map the space

    • AP Placement Points

      • Dual-purpose AP placement and channel use (this is most accurately planned in RingMaster)

      • Dedicated Location AP placement to fill in & ensure the required location precision

    • Locale boundaries

    • RF Fingerprint sites

  • Network Topology

    • The Physical topology

      • Cabling distances, LA-200 siting

    • Logical topology

      • IP subnet configuration, DHCP scopes, DNS Host entries for the LA-200

Trapeze Networks, A BELDEN Brand | Proprietary and Confidential | 8/14/2014 Slide 31


Identify locale boundaries

Identify Locale Boundaries

  • Selecting Locale Boundaries

    • Identify appropriate Locales and name them

      Note: Locales do not have to be delimited by walls/partitions

  • The Locale boundaries determine the granularity of tracking

    • ‘4th Floor’ may be too large a Locale to be useful for tracking

    • ‘Conference Room – NW Corner’ may introduce extra calibration work

    • Balance by chunking up similar nearby space, e.g.

      • ‘4th Floor NW Cubes’

      • ‘4th Floor Main Conference Room’

    • Create a naming convention to logically identify Locales

  • Locale definitions may be imported into the LA-200

    • XML structured import file

  • Client Location Tracking

    • Clients are tracked to the best fit Fingerprint but are reported by the Locale name

    • The calibrated RF Fingerprints may form the basis of the XY coordinates reported by the LA-200 through the API

Plan location ap placement

Plan Location AP Placement

  • Dual-purpose APs

    • APs providing service to client devices can also be used as Location APs

    • Such dual-purpose APs can only Snoop traffic on their operating channel

      • Set ‘Active’ or ‘Passive’ scanning to the ‘Operating’ option

    • If dual-purpose APs are used for location, the effective number of Location APs that will see a particular client will be a subset of those within range of the client, e.g.

      • For a channel set of 1, 6, 11 the under subscription ratio is 3 (i.e. only every 3rd AP will see the client)

        Note: when tracking location tags that radiate on all of the in-service channels, all Location APs within range will see the tags

  • Dedicated Location APs

    • APs may be dedicated as Location APs (radios in ‘Sentry’ mode)

    • Dedicated Location APs should be set for ‘Active’ or ‘Passive’ scanning on the ‘Operating’ channel only

  • Calibration Guidelines

    • Ideally 8 Location APs should be visible at every Fingerprint location

    • If necessary add dedicated Location APs to resolve a shortfall

Trapeze Networks, A BELDEN Brand | Proprietary and Confidential | 8/14/2014 Slide 34


Plan location ap placement1

Plan Location AP Placement

  • Planning Process

    • Plan for Service first: use RingMaster to compute and place sufficient APs for the required coverage and capacity and to plan channel assignments

    • Fill in as necessary: add dedicated Location APs to ensure the location precision required especially in areas where location is critical

    • Refine AP locations: based on the Locale Boundaries, especially in areas where tracking is of heightened importance

    • Magic Number: 8 Location APs can sense each device

  • Location AP placement guidelines

    • Use a minimum off 12 Location APs

      • Location APs should not be too close to one another

    • Plan for 1 AP per 2500 – 3,000 sq ft (250 – 300 sq m)

      • Total the floor area for all floors in the building and divide by 2,500 – 3,000

        Note: Location APs work better in 3 Dimensions ! APs on the floors above and below contribute to a stronger location solution

    • Place Location APs 10 feet (3m) from outside walls or important boundaries

    • Place Location APs 8-12 feet (2.5-3.5m) off the floor (i.e. ceiling height)

    • Avoid elevator shafts

Plan the rf fingerprint sites

Plan the RF Fingerprint Sites

  • Plan the RF Fingerprint sites

    • Make an initial Fingerprint plan from the floor plans

    • There MUST be at least 1 RF Fingerprint per Locale

    • Revise and rename the plan with feedback from the client

    • Expect to add Fingerprints on site as required

    • Use each AP to create an RF Fingerprint

      Note: it is recommended that all APs be fingerprinted during calibration

  • RF Fingerprint definitions may be imported into the LA-200

    • XML structured import file

  • On average, expect one RF Fingerprint every 500 sq ft (50 sq m)

    • Might be less dense for more open spaces

    • Might be more in critical office space

    • The RF Fingerprint density controls location granularity

  • On average, expect to calibrate 40 RF Fingerprints in one hour

    • Roughly one hour for every 20,000 sq ft (2,000 sq m)

    • Calibration can be done by more than one person at a time

    • Calibration requires minimal instruction (interns can do it)
