Bluetooth Beacon Tracker leverages a set of Bluetooth Low Energy receivers (BLE nodes) that need to be deployed in the area to monitor. The nodes are programmed to detect Bluetooth signals transmitted by nearby Bluetooth Low Energy beacons (BLE devices) and report this information to the Accuware server. To ensure proper communication with the Accuware server the entire area with the nodes must be covered by a 2.4 GHz b/g/n Wi-Fi network. Note that the BLE nodes without our technology cannot be used to track and locate BLE devices.

Compatible nodes

Accuware provides the nodes to be used with Bluetooth Beacon Tracker, which are manufactured by Aprilbrother, Accuware’s technology partner.

BLE_NodeV2

We have chosen the Aprilbrother nodes for multiple reasons:

  • They are very cheap, reliable and very easy to configure.
  • They communicate via any 2.4 GHz b/g/n Wi-Fi network and this means that they don’t have to be connected to Internet using Ethernet cables.

Compatibility with other type of nodes: not all the BLE nodes are compatible with our system. Please submit a support request using this form and send us the exact model of a particular BLE node so we can take a look at the specifics and verify if it is compatible with our system.

Purchase the BLE nodes

Accuware provides directly the BLE nodes, please fill this form to place your order.

Electricity

The nodes can be powered using any power source with an output of 5 Volts and at least 1 Ampere (like USB power supplies and portable power banks). When purchasing USB power supplies please make sure to choose USB power supplies that meet the electricity standard of the country where the nodes will be installed (otherwise you might damage your nodes or the USB power supplies).

  • Power supply cable: USB to 3.5-1.35 mm DC plug included in the package.
  • USB power supply: not included in the package.

Detection radius of the nodes

The detection range depends on the physical location of the node. We have observed an average detection radius of up to 30 meters (in open spaces).

Requirements of the Wi-Fi Internet connection used by the BLE nodes

In order to communicate with the Accuware server, the BLE nodes need to be able to connect to one permanent 2.4 GHz b/g/n WiFi network that covers entirely the area in which the BLE nodes will be installed. The BLE nodes don’t have an Ethernet interface. These are the network requirements that MUST be met by the permanent network:

  • Accessible domain: its.accuware.com and navimote2.navizon.com
  • Ports (opened outbound): 53/tcp (DNS), 80/tcp (HTTP), 443/tcp (HTTPS), 1883 and 8883
  • Wi-Fi Security: no password, WEP-Personal, WPA-Personal , WPA2-Personal, WPA-Enterprise
  • Wi-Fi frequency:  2.4 GHz
  • Wi-Fi standard: b/g/n
  • Wi-Fi bandwidth: 20 MHz
  • Wi-Fi splash page/captive portals: there MUST NOT be a splash page/captive portal. If there is a splash page/captive portal then you should ask to the ​network administrator to add to a white list the MAC addresses of the BLE nodes.
  • Proxies: the BLE nodes can’t works with proxies. If there is a proxy inside the WiFi network used by the BLE nodes it is necessary to ask to the IT department the company to add an exception to the proxy to allow the BLE nodes (identified by their MAC addresses) to connect without credentials to the domains listed above using the ports listed above.

The BLE nodes are able to connect to Wi-Fi access points from up to 50 meters away.

No Wi-Fi network available: if you can’t provide Internet connection to the BLE nodes through a Wi-Fi network already available in the environment, there are different alternatives that you could take into consideration:

  • you can purchase a portable Wi-Fi router in order to share a 3G/4G/LTE Internet connection through Wi-Fi.  At this link you can find some examples.
  • OR you can purchase the OM2P or OM2P-HS access points and create a WiFi network following the network planning guide available here.

Interference with other Wi-Fi networks

The BLE nodes operate in accordance to the IEEE 802.11 b/g/n protocol. In particular the BLE nodes:

  • do not interfere at all with the 5 GHz Wi-Fi networks because they use only the 2.4 GHz frequencies.
  • do not interfere with Wi-Fi networks that use channels that don’t overlap with the channels used by the permanent WiFi network. This means that if an existing Wi-Fi network uses channels from 1 to 6 and the permanent WiFi network is set to work on channel 11, there will be no interference between the 2 networks.
  • interfere very little with other networks that share the same 2.4 GHz channel that is used by the permanent WiFi network because the amount of data sent by the BLE nodes to the permanent WiFi network is minimal (as explained in the next paragraph).

Bandwidth used by the BLE nodes

The infrastructure of BLE nodes is mostly passive. The amount of traffic generated is very low and proportional to the amount of BLE devices detected in the environment. Each BLE node typically transmits on average about 9 MB/hour (assuming that the BLE node is detecting 30 BLE devices constantly every 3 seconds). It is clear that the traffic produced by the BLE nodes has negligible impact on the bandwidth and on the channel capacity, especially at 802.11 n speed.
