Indoor Anchor A1102P (Single Network Port/POE Power Supply)

Indoor Anchor A1102P

The UWB real-time location system is a TDOA location system using UWB wireless communication technology, with a location accuracy of about 30~50cm.

Both Anchors, A1102P and A1106P, are ceiling-mounted and are usually used indoors. The power supply methods are all POE power supply.

The anchor can be configured as a location anchor or clock source. When configured as a anchor, it is responsible for receiving the UWB location signal sent by the tag and the clock synchronization signal sent by the clock source; when configured as a clock source, it periodically sends the clock synchronization signal. The latest version of the firmware allows the anchor to function as a normal anchor and clock source at the same time.

A1102P is a single network port anchor, connected to the POE switch through a network cable.

Main features:

1. As a UWB location anchor, receive UWB location signals sent by tags
2. As a UWB clock source, regularly send clock synchronization signals to keep the clocks of anchors in the area consistent
3. Use POE power supply, no need to provide additional power supply
4. The IP address can be specified or automatically assigned through DHCP.
5. Automatic discovery by location engine.
6. Each anchor has an EUI64 ID that complies with the EUI specification.
7. The clock synchronization signal sending interval is configurable
8. The PAN ID can be configured to filter irrelevant UWB packets.
9. The clock can be synchronized with up to 5 clock sources for location.
10. The preamble length/PRF/PAC of UWB communication data packets can be configured.
11. The anchor firmware can be upgraded.

The A1102P anchor is our initial main product and the highest-selling anchor.

This anchor has evolved through dozens of versions from the initial basic version. The main control MCU is STM32F103RET6, the network chip is W5500, and the UWB chip is DW1000. These three chips remain unchanged, and we have achieved firmware compatibility, which is compatible no matter how the hardware version changes or the firmware version changes.

For the initial version, we use the DWM1000 original module. In order to keep the UWB antenna farther away from the PCB, we made another conversion board for the DWM1000, welded the DWM1000 to the conversion board, and then welded the conversion board to the substrate of the anchor.

The old version of the conversion board is directly welded to the substrate, which brings some troubles to production. Because if the factory welds it, the adapter plate on the PCBA will be a bulge, which is difficult to package during transportation and is easily damaged. If we weld by ourselves, our workload will increase, and the cost of having engineers do the work of welders will be too high. So, we changed to pin header connection.
