What is Bandwidth Efficiency

Chapter 5
Handbook of Research on Implementation and Deployment of IoT Projects in Smart Cities
It can be defined as the effective and useful use of every Hertz of frequency available for communication. In radio communication, bandwidth efficiency is essential as the available spectrum for communication is very limited. Bandwidth efficiency can be increased through spectral efficiency (by increasing the number of bits per hertz).

Abstract
Internet of things (IoT) is an integral part of modern digital ecosystem. It is available in different forms. Narrowband IoT (NBIoT) is one of the special forms of the IoTs available for deployment. It is popular due to its low power wide area (LPWA) characteristics. For new initiatives such as smart grids and smart cities, a large number of sensors will be deployed and the demand for power is expected to be high for such IoT deployments. NBIoT has the potential to reduce the power and bandwidth required for large IoT projects. In this chapter, different practical aspects of NBIoT deployment have been addressed. The LPWA features of NBIoT can be realized effectively if and only if its deployment is done properly. Due to its large demand, it has been standardized in a very short span of time. However, the 5G deployment of NBIoT will have some new provisions.
