5.8 Locationing

5.8.1 RTLS Overview

Locationing (also called Real Time Location-based Services and Real Time Location Application Services)
delivers end-user applications based on:
• The location of mobile devices (devices with location enabling technology, such as a WiFi supported
handheld, Wi-Fi laptop or cell phone)
• The location of an attached tag (a location enabled mobile device in miniaturized form, for example a
WiFi tag, UWB tag or RFID tag that is attached to a person, vehicles or a package)
A Motorola wireless LAN switches (such as a RFS7000) can facilitate true RF technology-agnostic mobility,
allowing customers to view, manage and troubleshoot their RF network (Wi-Fi, RFID, UWB, mesh etc.) and
provide accurate asset locationing information across multiple networks in real-time. This solution can also
be packaged as a locationing appliance.

5.8.2 SOLE - Smart Opportunistic Location Engine

SOLE is an on-board location engine using a combination of innovative algorithms to determine location
based on asset type. SOLE fuses the location information reported by several technologies into one seamless
environment to get more meaningful results.
SOLE helps locate assets (including rogues) including passive tags, semi-passive tags, active tags
(UWB,802.11, RFID etc) and MUs. SOLE returns the location of passive tags as seen by mobile RFID readers
(like a MC9090) by combining the 802.11 reader's location with RFID antenna direction/location data.
Applications (users) inform SOLE (RF switch) about a facility map, location of infrastructure and zones. A zone
is an area of specific interest with respect to whenever an asset becomes visible or invisible in that area.
SOLE uses the following input variables as needed for the specific tag type calculating location:
• User configurations
• RSSI propagation based on facility layout and RF barriers as specified by the user
• Smart surroundings (fixed wireless devices such as printers, price verifiers, near me tags as installed in
the facility)
• Runtime RF environment
• The previous position of the tag
• TDoA
• AoA
