Capitalised terms are terms defined in this article. 

Attendance / Attendants

The number of unique Devices determined as having been in a Region over a specified time period. So for an Event, the higher the count, the more popular the Event. In the Insight module a Dashboard readout displays a Weighted figure for the past hour.


In the Engage module Broadcast messages are sent simultaneously to everyone who meets the Segment rules at the send time. Contrast with Triggered messages.


In the Insight module, the Dashboard user interface enables quantitative real-time readouts of visitor data to be displayed. You can have as many Dashboards as you like, building each Dashboard to custom requirements by combining multiple Widgets. Dashboards can be shared on a read-only basis with others (Shared Dashboards) or remain private (locked) for view by the individual creator only. Use the padlock icon to switch between shared and private.

Data Tables

Data processed by the Colocator system is collated into a set of CSV files. These Data Tables provide statistical information about Regions, Events and Messages that can be used for post event analysis and reporting. Data Tables are made available in the Download sections of the Admin User Interface (cog icon in the top right hand corner).


The area of a Region (in square metres) divided by the number of Devices located in that Region.


A piece of hardware that reports a location fix, a range or a signal strength to the Colocator platform (most frequently this will be a mobile phone running an app in which Colocator code is embedded).  

Dwell Time

The average duration of Visits to a Region at a particular time. This is different to the Time Spent which is the sum of the durations of all the visits made to the Region within a particular time range. When used in a Dashboard Widget, Dwell Time displays average weighted visit duration (from entry to exit) of visits with an exit in the last 10 minutes. If you add up all the time spent in an area and divide it by the number of devices that went there you get average dwell. The average amount of time a device spends in an area.


A prescribed happening in a certain Region during a specified time period (i.e. with a start and end time). An artist set on a stage, for example, constitutes an Event.


In the Engage module a filter is the lowest level rule that specifies where Devices are (or were) at particular times. Segments can be built by combining Filters, and/or by combining other Segments. Filters and Segments are also used in the Query Builder interface within the Analytics module.

Flash Report

A report in PDF format showing the occupancy profile of certian Regions and the attendance of Events in those Regions, typically available overnight.

Flow In / Flow Out

The number of entries or exits to/from a Region during a certain time window (e.g. for a Dashboard this is the past 60 minutes on a Weighted basis). If a Device enters/exits twice, it is counted twice.


The number of Visits (NB not unique Devices) that commence in a given time period (e.g. 5 minutes).


A graphical representation of the location of connected Devices overlaid on a map. Colocator provides real-time Heatmaps and historical animated Heatmaps (for replay; downloadable as MP4 movie files within the Analytics Module) that show how the density of devices change over time. There are controls to set the intensity, radius and blur of the Heatmap, and for historical replay, to choose the number of frames.

Message Throttling

A limit on the amount of messages a device can receive within a specified time period. See here for more detail on Message Throttling.

Occupancy / Occupants

The number of Devices located in a specified Region at a specific time (e.g. based on the past one minute of data when displayed in a Widget on a Dashboard). Consequently Max Occupancy is the maximum number of Devices located in a Region (in a Dashbaord this is based on the last hour's worth of data).

R4 score

Crowd Connected's proprietary methodology for evaluating message impact, combining the following metrics:  

Reach –The total target group size, i.e. the number of devices that are sent a geo-targeted push notification message. 

Relevance –The percentage of the Reach group for whom the message is relevant. For recommendations to visit a certain Region (during a certain time period, if relevant - i.e. during the time of an Event) this is the group that were located at the Region (during an Event, if relevant), either because they would have been anyway, or because they were persuaded to go by the message.

Reaction – The percentage of the Reach group that, based on our methodology, we believe modified their behaviour because of the message, i.e. they wouldn’t have visited the recommended region (during the specified time period, if relevant) if the message hadn’t been sent. Frequently this is the primary metric for measuring the effectiveness of a message. A positive Reaction means the message made people more inclined to follow recommendation. A negative Reaction means the message made people less inclined to follow recommendation. A neutral Reaction means we measured a very low effect either way.

Result –The percentage uplift in the audience size that we can attribute to the message, based on our methodology.

See Message Impact Analysis.


A defined polygonal area of any shape or size drawn on an online map and/or site plan using Colocator’s mapping interface. Regions can overlap and be located anywhere (i.e. not restricted to event site). You can think of Regions as geo-fences (in realtion to targeting messages) or areas of interest (in respect of reporting footfall metrics).

Sankey chart

A chart in the interactive charting (see Analytics module) that shows the relative proportions of Visits to each Region and the relative flows to and from the Regions that are visited next and immediately prior to the Visits to the current Region


Colocator tracks connected Devices (mobile phones, tags, beacons, etc) which will be a sample of visitor numbers. Where a reliable and regular external count is provided (for example from the gates), we are able to scale from Devices to an estimate of people for certain reporting metrics (e.g. for Occupancy). See here for how scaling sampling can be applied. 


In the Engage module, a Segment is a group of Devices (i.e. a fraction of the audience) that all meet certain defined criteria. Segments can be built by combining Filters, and/or by combining other Segments.

Time spent

See Dwell time. 


In the Engage module Triggered messages are sent to each person individually as and when they meet the Segment rules, during a specified time window. See also Broadcast.

Visit Time

If you add up all the time spent in an area and divide it by the the number of visits to that area you get visit time. The average length of a visit to an area.


A Visit commences when a Device enters a Region and ends when a Device exits the same Region. A Device can make multiple Visits to the same Region. 

Weighting / Weighted

Mobile phones can be switched on/off, they can run out of battery, permissions can be changed and apps can be installed/uninstalled. The population of devices that is reporting locations therefore changes over time. Colocator utilises proprietary Weighting algorithms to account for this changing population of active devices. In other words, Weighting is a sample rate adjustment. Weighted figures are displayed in Dashboards. Data Tables also include Weighted outputs (alongside figures without Weighting adjustment. 


In the Insight Module a Dashboard is created by assigning one or more Widgets to it. A Widget is simply a display of real-time data from one or more Regions. There are a large number of different Widgets available listed in full here.
