Comparative analysis of the Internet of Things (NB-IoT) and other wireless communication approaches

As a result of the fast expansion of low-data-rate IoT services in an intelligent manner, LPWA technology is gaining more and more popularity in the business world, and its market share is progressively expanding. As stated in the study that Hequan Wu presented at the China Internet of Things Conference in 2016, intelligent Internet of Things applications may be divided into three groups according to the data transmission rate requirements that will be in place in the year 2020 or later.

HIGH RATE OF DATA TRANSFER: 

The speed at which data is sent is faster than 10 Mbps. 3G, 4G, and Wi-Fi are the entry methods that can be used. They are used mainly in direct television broadcasts, electronic health care, guidance and entertainment systems for cars, etc. 10% of the market is projected to be IoT apps. 

MEDIUM RATE OF DATA TRANSFER: 

The speed at which data is sent is less than 1 Mbps. 2G and MTC/eMTC are the connectivity methods that can be used. A POS machine, a smart home, and an M2M return link are all examples of that use. 30% of the market is expected to comprise these IoT apps. However, in the future, MTC/eMTC technology will slowly replace 2G M2M. 

LOW RATE OF DATA TRANSFER: 

The speed at which the data is sent is less than 100 Kbps. NB-IoT, SigFox, LoRa, and short-range radio connectivity like ZigBee are the entry technologies that can be used. They are primarily used in low-power wireless technologies, such as sensors, smart meters, tracking items, transportation, parking, and smart farming. 60% of the market is expected to comprise these IoT apps. On the other hand, there are still a lot of open positions in the related market. Because of this, NB-IoT will do well in the future.

Ways that NB-IoT can work 

 1. Can be used by itself 

 The stand-alone mode uses a separate carrier, like the bandwidth that GSM EDGE Radio Access Network (GERAN) systems use now, instead of one or more GSM carriers. In places where cellular services aren’t available or are being turned off, this is used to make a narrow bandwidth available, like cellular GSM. Changing how one or more GSM providers work to allow NB-IoT data will make the switch to LTE for contact between many machines go smoothly. 

 2. The Guard Band 

 This mode uses resource blocks that aren’t being used in an LTE carrier’s guard band. This method is used when cellular services are available and NB-IoT is in the LTE guard band. 

 3. In the band 

 In this mode, resource blocks in a regular LTE carrier are used. This method is used when cellular services are available and NB IoT is in the LTE guard band. This way of working saves cell providers money and time because they don’t have to change hardware. Depending on what users or devices want, it also uses frequency resources for LTE or Narrowband-IoT services. 

Applications and Use Cases for NB-IoT
