Overview
The Controller Area Network (CAN) is widely used in automotive and industrial applications. The CAN FD is a freestanding controller for the CAN. The Bosch CAN 2.0B standard (2.0B Active) and the CAN FD (flexible data-rate) are both met by the CAN FD, which was created in line with ISO 11898-1:2015.The success of CAN is largely due to its sophisticated error detection features, which improve communication reliability, and its unique fault confinement, which ensures network-wide data consistency. Reliable implementations are essential due to their basic importance in all facets of security and safety. The enhanced protocol surpasses the limitations of the original may: data may be carried at a rate more than 1 Mbit/s, and the payload (data field) is no longer restricted to 8 bytes but can now be up to 64 bytes long. Because there is only one node sending, the data rate may be raised.

The adoption of the Bluetooth low energy (Bluetooth LE) specifications v4.0/v4.2 standards is being driven by adoption in several markets such as the Health and Fitness devices, Beacons, Asset tracking, Home automation, PC Peripherals etc. Bluetooth low energy 5, together with the Bluetooth LE Mesh specifications are set to make Bluetooth the ‘Connectivity of Choice’ in IoT markets such as Connected Home, Commercial Lighting and Industrial Wireless Sensor Network markets.
It is very important that the design aspects of the NB-IoT device protocol stack ensure low module cost and low energy consumption. This is required to match the industry expected module costs. This paper outlines some of the NB-IoT Protocol stack specification flexibilities and generic design aspects that are to be considered to meet the above requirements, especially with reference to LTE.
