Description

The UM-1 Module is a full-function RTLS /

wireless modem subsystem in a compact factor,

composed of Qorvo DWM1001 hardware, and

WizziLab proprietary firmware. The UM-1 module

enables customers to quickly get a RTLS system

up-and-running, also provides

additional over-the-air communication

capabilities through the UWB, BLE and NFC

interfaces. The UWB part of the system is

designed to operate on 4.493 GHz (IEEE

802.15.4- 2011, Channel 3) and 6.490 GHz

(IEEE 802.15.4- 2011, Channel 5) Nominal

Centre Frequencies with a 500 MHz

Bandwidth and data rates of 110 kbps and

850 kbps. It also features a BLE modem and

a passive NFC-A listening device.

UM-1 Overview 1 Overview The UM-1 Module is a full-function RTLS / wireless modem subsystem in a compact factor, composed of Qorvo DW1000 hardware, and WizziLab proprietary firmware. 1.1 UWB Transceiver DW1000 The UM-1 module has a DW1000 UWB transceiver mounted on the PCB. The DW1000 uses a 38.4 MHz reference crystal. The crystal has been trimmed in production to reduce the initial frequency error to approximately 3 ppm, using the DW1000 IC’s internal on-chip crystal trimming circuit.

The UM-1 module enables customers to quickly get a RTLS system up-and-running, also provides additional over-the-air communication capabilities through the UWB, BLE and NFC interfaces. The UWB part of the system is designed to operate on 4.493 GHz (IEEE 802.15.4- 2011, Channel 3) and 6.

UM-1 Functionality format. A device, supporting the tap-to-connect protocol, can establish BLE connection with the tag. The procedure is initiated by an NFC access event that triggers the immediate exit from monitoring mode and disabling of all DASH7 (sub-GHz) and UWB interfaces. The tag start blinking in blue. The tap-to connect is meant to be used as an alternative for configuration and report dumping.

UM-1 How to use 6 How to use 6.1 Serial API The device can be controlled by a separate host over the UART or SPI serial port. The API is based on the open ALP specification, elaborated by the D7A Alliance [6]. Please contact WizziLab for a detailed description. 6.2 Function API The same firmware is also available as a stand alone, non modifiable library, which provides a function API. This allows to execute the host firmware directly on the MCU of the UM-1.
