What is Narrow Band Internet of Things ( NB IoT)
- Narrow Band IoT is new standard connecting Internet of Things . NB IoT is new of communication with things.
- It is also known as LTE Cat NB1 is Low Power Wide Area (LPWA) technology that works virtually anywhere.
- Narrow Band IoT module is a low Power Area Network (LPWAN ) radio technology standard developed to enable wide range of devices and services to be connected cellular telecommunication bands.
- It is consider as narrrowband radio technology designed for the Internet of Things and it is also one of the range of mobile IoT (MIoT) technologies.
- It focuses specially on indoor coverage as well as low cost , long battery life and enable alarge number of connected devices.
- NB IoT significantly improves the power consumption of user devices , system capabilities and spectrum efficiency. Battery life of more than 10 years can be supported for a wide range of use cases.
NB-IoT Provides
- Very low power consumption
- excellent extended range in building and underground
- easy devlopment into existing cellular network architecture
- network security & reliability
- lower component cost

NB-IoT challenges
There are many potential ” connected things” are located in remote areas , at long distances from next cellular base station.
NB-IoT will connect many devices to the Internet of Things .It also make many new application . It is optimized for application that need to communicate small amount of
data over long peroids of time. Since it operate in licensed spectrum. It is secure and reliable providing guaranted quality of service.
Using other cellular air interfaces for typical NB-IoT application would be too expensive as NB Iot application don’t need all their capabilities . NB IoT application also focus on low speed , robust data transfer and appropriate level of reliability . A low device price also cuts the installation cost and reduces the risk of theft.

Smart Metering
NB-IoT is well suited for monitoring gas and water meters via regular and small data transmission. Networks coverage is a key issue in smart metering roll outs. Meters having strong tendency to turn up in difficult location. NarrowBand IoT has excellent coverage and penetration to address this issue.

Smart Cities
NarrowBand IoT can help local government control street lighting determie when waste bins need emptying identify free parking spaces monitor environmental condition and survey the condition of roads.

Smart Buildings
NB-IoT have connected sensor which can send alert about building maintaining issues as well as it can perform some automated task such as light and heat control.
NB-IoT can also act as the backup for the building broadband connection . Some security solution may even use LPWA netwok to connect sensor directly to monitoring the system as this configuration is more difficult for snooper to disable as well as easier to install and maintain.
