RAK13801 WisBlock UWB Module Datasheet

Overview

Description

RAK13801 is a WisBlock IO that extends the WisBlock system based on Decawave's DW1000 module. This module uses a UWB (Ultra Wideband) Technology, a short-range wireless communication similar to Wi-Fi or Bluetooth and it uses a frequency bandwidth above 1 GHz. It has an integrated antenna, all RF circuitry, power management, and clock circuitry in one module. It can be used in 2-way ranging or TDOA location systems to locate assets to a precision of 10 cm and supports data rates of up to 6.8 Mbps.

Features

• Power supply: VBAT
• Chipset: Decawave DW1000
• Operating temperature: -40 °C ~ 85 °C
• Very precise location of tagged objects delivers enterprise efficiency gains and cost reductions
• Extended communications range minimizes required infrastructure in RTLS
• High multipath fading immunity
• Supports very high tag densities in RTLS
• Low cost allows cost-effective implementation of solutions
• Low power consumption reduces the need to replace batteries and lowers system lifetime costs
• Module size: 35 x 25 mm
