The NL865B1 is the Category NB1 evolution in the widely deployed Telit xL865 product family. Specified in the Release 13 of the 3GPP standard, LTE Cat NB1 is specifically tailored for IoT applications, offering optimized power consumption and enhanced coverage. In addition, with its square24.4 x 24.4 mm VQFN footprint, the NL865B1 is designed for size
This next generation of products supports the new features specified by 3GPP to boost IoT applications, such as the Power Saving Mode (PSM) and the extended Discontinuous Reception (eDRX), which allow the devices to wake up periodically to deliver only very small amounts of data to the network and then go back to sleep for most of the time, thus allowing longer battery operation. Enhanced coverage, with up to +20dB in maximum coupling loss (MCL) com-pared to the other cellular technologies, is also one of the key benefits of this new LTE flavour. LTE Cat NB1 devices are therefore optimized in cost, size and power consumption compared to higher UE categories. These advantages make the NL865B1 the perfect platform to enable a quick implementation of LTE technology in IoT/M2M where low cost and low power are more relevant than high speed.
The NL865B1 helps increase the addressable market for LTE technology to include a broad range of new applications and use cases best served with lower maximum data rate, ultra-low power, reduced complexity and cost. Some examples are smart metering, smart parking, smart agriculture, waste collection, industrial sensors, healthcare monitors, home automation, and many more low data rate IoT devices. The NL865B1 is offered in a dual-band con-figuration for deployment in the European and Chinese NB-IoT networks, either in in-band, guard-band or standalone mode; additional regional variants will follow. It is highly recommended for new designs, but also in particular as a migration path for existing GPRS devices, both new and updated designs benefit from a significant extension in lifecycle with LTE Cat NB1. The NL865B1supports embedded SIM chip as a mounting option, making it the ideal solution for durable and rugged designs, and reducing BOM cost and size on the customer's application.
