Locationing
Controller Management (CLI, SNMP or Applet)
Controller Management plays a key role in defining and configuring the multiple Geofencing zones.
This includes configuration of site parameters including site dimensions, zones and Access Point
locations.
Each zones perimeter must include a minimum of 3 points and must not exceed 16 points.
Additionally the zones perimeter must not overlap another defined zone. Each Zone is assigned a
ZoneID which is in turn used in creating the ACLs which will deny admission within that specific
zone. The following figure shows some sample zones

Locationing (also called Real Time Location-based Services and Real Time Location Application
Services) delivers end-user applications based on:
•
•
A Brocade WLAN controller 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.
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 Clients. 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 controller) 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:
•

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)
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
