Hyperlocation Antenna

Just a quick post to give some insight into the Cisco Hyperlocation module

Cisco released a little while ago their Hyperlocation module for the 3600 and 3700 AP series. This technology proposes to enable wireless location of associated clients of between 1-3m.
If this technology holds up to its claims of 1-3m accuracy it will have great wireless analytic use cases, without having to rely on beacons.

The parts required to use Hyperlocation are broken down into Software and Hardware:

Minimum Software Requirements for Hyperlocation

  • Cisco Prime version 3.0 or higher— The function of this software is to correctly place the Access Points on a map and describe the orientation of the Antenna. Exporting maps to CMX 10.2.x. Note: I recommend Prime 3.2 or later as it has improved mapping functionality which allows more accurate AP placements. The deployment guide states:

    The location needs to be accurate down to several inches

  • Cisco CMX 10.2.1 or higher— The function of this software is to receive the information from the Hyperlocation module and antennas and then calculate the location. Furthermore, it provides this location via a display on a map of client locations and an API with the calculated location. The L-AD-LS-1AP-N – CMX Advanced License for 1 AP is required.
  • Cisco Unified controller 8.1(MR3) or higher— The function of this software is to support the new hardware and provide a tunnel for the information from the WSM to get to the CMX 10.2.1 server
  • In addition to these components, you will also need an NTP server (application or router running on same subnet) as you will need to configure the controller to sync with an NTP server through the Hyperlocation settings. You will also need to configure a gateway on the switch and controller.

Minimum Hardware Requirements for Hyperlocation

  • Suitable Cisco controller such as 2500, 5508, 5520 etc. running 8.1(MR3) or higher
  • AP-3600 or AP-3700 These are the current Cisco Access Points supporting Hyperlocation modularity
  • AIR-RM3010L-x-K9= Hyperlocation Module with Advanced Security
  • AIR-ANT-LOC-01= Hyperlocation Circular Antenna
  • Wireless clients (tablets, smartphones and so on). Note: The client must be associated to the network advertised from the APs

The Hyperlocation Circular Antenna is made up of 32 directional antennas to allow location to be calculated based on Angle of Arrival (AOA)

The Hyperlocation Deployment guide is located here

I have two posts coming up where I put hyperlocation to the test in a walled office and open plan office environments.

The reason for the two different office environments are due to a little clause that is hidden in the deployment guide stating:

A general rule of thumb is to have 3 or 4 access points that are within line of sight of the device at a distance of less than 70 feet

In a traditional walled office environment meeting this requirement is not always achievable without increasing the overall cost.

Interestingly when this product first came out on the market, the sales guys were promising that it would eliminate the requirement to install a RTLS design and you would get 1-3m accuracy with data designs (including hallway designs) this has been proven inaccurate (from my own testing) and you still need to install a RTLS design with the hyperlocation modules being on all APs.

Future CMX releases have it slated to allow a mix of RTLS and hyperlocation areas on a single floor, allowing you to deploy an RTLS design to the floor and hyperlocation to the areas you require the greater accuracy but this will need to be seen when its released.

I have two upcoming posts which I have put Hyperlocation to the test in both a walled (brick walls) office and a newer open planned office showing the comparison of RTLS vs Hyperlocation so you can make up your own minds if the additional costs result in the greater accuracy you require.
