Cat NB2 NB-IoT USB Dongle Package
- LTE Cat NB2 USB dongle with LTE antenna connector.
General Description
Overview
The NB-IoT USB dongle is a cellular USB stick form factor based on Quested BC660 chipset. BC660 is a high-performance NB-IoT module with extremely low power consumption.
The USB dongle has on-board LTE antennas. It features a wireless modem. The
wireless modem is BC660 which is an embedded IoT (LTE Cat-NB2) wireless
communication module. BC660 wireless modem provides a maximum data rate of
127Kbps downlink and 158.5Kbps uplink. It features ultra-low power
consumption, provides data connectivity on LTE/5G networks, and supports half-
duplex FDD operation in LTE networks.
The USB dongle provides rich sets of Internet protocols, industry-standard
interfaces (USB/UART/SPI/ADC/GPIO/RI/Status Indicator) and abundant
functionalities. The board offer a high integration level and enables
integrators and developers to easily design their applications and take
advantage of the board low power consumption, many functionalities, and USB
drivers for Windows 7/8/8.1/10, Linux and Android.
The USB dongle is a rich hardware board that can be used for the 4G LTE wireless technology and enables a variety of smart applications for devices. It enables large number of applications such as wireless POS, smart metering, tracking, smart transportation, smart buildings, smart city, smart homes, bike sharing, smart wearables, smart parking, home appliances, security and asset tracking, agricultural and environmental monitoring.
