Functionality UM-1
5 Functionality
5.1 General Purpose
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. 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.
5.2 Two-way ranging
The UM-1 provides two-way ranging function (TWR), as described in the DW1000
Datasheet [2]. The ranging is performed through the exchanges of 4 timestamped packets
allowing to compute a time of flight estimation. The initiating device and the target device
are awoken though an out-of-band event, so the TWR does not involve any polling,
repetition, or any other transmission activity aimed to maintain a link between the devices.
The TWR routine does not exceed 100 ms, transmission periods do not exceed 10 ms.
5.3 DASH7 over UWB
The UM-1 embeds a D7A protocol stack for the purpose of exchanging data between nodes.
The stack is an implementation of the open specification elaborated by the D7A Alliance [7],
which is by construction connectless (it is based on an asynchronous MAC). Transmission of
data is initiated by the application. A DASH7 transaction is a single request followed by a
single per-device response. The DASH7 protocol does not involve any polling, or any other
continuous transmission activity in aimed to maintain a link between the devices. The DASH7
routine does not exceed 100 ms, transmission periods do not exceed 10 ms.
5.4 BLE beaconing and sniffing
The UM-1 embeds a BLE protocol stack, based on the Nordic Semiconductors SoftDevice
library. The device supports tap-to-connect, beaconing and sniffing functions, in Eddystone
and Ibeacon format.
5.5 Tap-to-connect
A device, supporting the tap-to-connect protocol, can establish BLE connection with the tag. The
