LOCALIZATION WITH UWB

The fine ranging and positioning capabilities of UWB

technology bring precise location and convenience to a

variety of use cases, including secure access control, indoor

positioning, and device-to-device communication for item

tracking and tag location.

UWB securely determines the relative position of peer

devices with a high degree of accuracy. The use of

wideband spectrum means UWB uses little power to send

signals and provides stable connectivity with minimal

interference.

UNMATCHED ACCURACY

Compared to other wireless technologies, including Wi-Fi

and Bluetooth

, which can narrow an item’s location to

within an area of about 150 cm under ideal conditions,

UWB has a location accuracy of 10 cm, and requires fewer

anchors to cover the same area.

UWB can be used outdoors to locate objects very precisely,

down to the centimeter level, and can be used indoors,

where GPS has difficulty operating, to extend navigation

capabilities.

NXP achieves excellent precision and robustness with UWB

and was first to offer a system-level UWB solution backed

by a comprehensive software offering and strong security

integration based on NXP’s market-proven embedded

secure elements (eSEs), and near-field communication (NFC)

integration.

TRIMENSION SR150 FOR IOT DEVICES AND ANCHORS

The Trimension SR150 IC is both forward and backward

compatible with IEEE 802.15.4 HRP UWB. The 500-MHz

bandwidth, with a pulse rate of 2 ns, supports high-resolution

ranging, with LoS accuracy within a range of ±10 cm. The Tx

peak power is more than +10 dBm and the receiver noise

figure is +4 dB.

Delivered in a WLCSP68 package, the Trimension SR150

has, at its core, an Arm

Cortex

-M33 CPU with TrustZone

Integrated security hardware accelerators protect overall

operation for high-level RF security. A dual-Rx antenna

setup enables two channels for AoA functionality, and an

onboard CoolFlux

BSP32 DSP is used for ToF, AoA, and

radar algorithms.

Building on IEEE 802.15.4z, the Trimension SR150 IC comes

with an added level of security, especially when used for

access control to protect the privacy that comes with the

exchange of access credentials. The added protections make

the Trimension SR150 IC more resistant to attempts to trick

the system, in what’s known as a relay attack, where hackers

attempt to intercept and amplify the wireless signal and

thereby open a lock, even though the key is not close by.

Several Trimension SR150 IC devices can be placed in a

room as UWB anchors to help localize people and objects

as they move within the room.
