Introduction to CMX Analytics
CMX analytics is a system that provides a set of data analytic tools packaged for analyzing Wi-Fi device locations that comes from the Mobility Services Engine (MSE). The CMX analytics service is part of advanced location service, that was integrated into the MSE in Release 7.4.
When a wireless device is enabled in a network, it transmits probe request packets to identify the wireless network in its vicinity. Even after connecting to the access point in the WLAN, the client devices continue to transmit probe request packets to identify other access points for better quality of service. The access point gathers the request and the associated Receiver Signal Strength Indicator (RSSI) from the various wireless devices and forwards them to the Wireless LAN Controller (WLC). The controller then forwards this information to the MSE for analysis.
The basic data that is collected from various APs, when analyzed, produces information and knowledge about the movement and behavior patterns of people who are using Wi-Fi devices in the building. For example, the building can be an airport, shopping mall, city center, and so on.
The CMX analytics system:
- Estimates the number of visitors, the amount of time they spend, and the frequency of their visits within a venue.
- Provides detailed insight into the behavior patterns of people moving and interacting within a venue.
- Analyzes business performance by measuring the effect of in-venue marketing.
- Improves customer satisfaction though sufficient staffing during peak times, proper signage, and make changes to the underutilized areas.

Workflow to Set up the CMX Analytics System
The following table describes the steps to be followed while setting up the CMX analytics system.
CMX Analytics Within the Cisco Unified Wireless Network
Cisco Unified Wireless Network (CUWN) solution ensures that your business achieves the highest level of network security and versatility. Cisco UWN solution empowers your network with the ability to offer secure wireless networking, either within your office for increased mobility or bridging between your office buildings. The following are the components of CUWN:
- Access Points—The Access point is the end point on the network side that provides the wireless access. The following access points are supported:
– Cisco Aironet 801, 802, 1000, 1040, 1100, 1130, 1140, 1200, 1230, 1240, 1250, 1260, 1310, 1500,
– 1524, 1552, 1600i, 1600e, 2600i, 2600e, 3500i, 3500e, 3500p, 3600i, and 3600e Series Lightweight Access Points.
– Cisco Aironet 1040, 1100, 1130, 1141, 1142, 1200, 1240, 1250, 1260, 2600i, and 2600e Autonomous Access Points.
– Cisco 600 Series OfficeExtend Access Points.
– Cisco Aironet Access Points running Lightweight Access Point Protocol (LWAPP) or Control and Provisioning of Wireless Access Points (CAPWAP) protocol.
- Wireless LAN Controllers—The WLAN controllers are highly scalable and flexible platforms that enables system wide services for mission-critical wireless in medium to large-sized enterprises and campus environments. Designed for 802.11n performance and maximum scalability, the WLAN controllers offer enhanced uptime with the ability to simultaneously manage from 5000 access points to 250 access points; superior performance for reliable streaming video and toll quality voice; and improved fault recovery for a consistent mobility experience in the most demanding environments.The controller actively manages these APs w.r.t what channel it operates, how does the client gets attach to it, what security types are supported and so on.
- Cisco Prime Infrastructure—With the Prime Infrastructure, network administrator have a single solution for RF prediction, policy provisioning, network optimization, troubleshooting, user tracking, security monitoring, and wired and wireless LAN systems management. Robust graphical interfaces make wired and wireless LAN deployment and operations simple and soft-effective. Detailed trending and analysis reports make the Prime Infrastructure vital to ongoing network operations.
- Mobility Services Engine—The Cisco MSE is an open platform that provides a new approach for delivery of the mobility services and applications. The MSE is managed by the Prime Infrastructure and supports various services.The Cisco 3300 Series Mobility Services Engine operates with CAS, which is a component of the CAM solution. There are two models of the mobility services engine:
– Cisco 3310 Mobility Services Engine
– Cisco 3355 Mobility Services Engine
The following figure shows the overall architecture within which the CMX analytics system fits in. The CMX analytics system contains the following components:

Getting Information on Your Network
The process of downloading and creating a database of devices or path information is automatic. If the installation is new, then the collection of data starts immediately and continues to download increments of data every 15 minutes. If you are upgrading to an existing MSE that has been collecting data, then the system downloads data from the previous 3 days or from the last successful download (whatever is shortest) before continuing every 15 minutes. The analytics is available immediately when the data is in the database.
Note Analytics is run on currently available data that is stored in the Analytics database. The amount of raw data is limited and is based on the available disk space on the MSE. For data to remain current, a rollover or pruning is necessary at some point. The number of days available for analytics is therefore depends on the amount of points able to be stored. Currently default is 8 million points pruned back to 7.9 million points. The reports however are run from an Aggregated or Summary database which is considerably smaller than the Analytics database. This holds data for a much longer period of time, which means that eventually the available dates for reporting will have a wider coverage than that for the analytics.
