(1) Band, cost, and quality of service products
Nb-iot and cellular phone use the operator's licensed spectrum, which is divided into different bands, so there is less interference, even though there are charges in practice.
Even though there are charges in practice, they also provide better quality of signal service, lte iot module security and authentication. The construction of cellular network base stations is more favorable for rapid and large-scale applications.
(2) Communication distance
The coverage range of NB-IOT signal depends on its base station density and link budget. With the advantage of previous resources, it can achieve a wider coverage range and better QoS than LoRa.
The network IoT itself has a connection budget of up to 164dB, enabling transmission distances of up to 15km and ~20km.
3. Low power consumption, low battery life
The nodes of NB-IOT synchronous protocol must be connected regularly, and the "peak current" is several orders of magnitude more than LoRa, especially from the base station to the server, which consumes a lot of battery power.

(4) Equipment cost
For node companies, NB-IOT protocols and modulation mechanisms are more complex to analyze and require more complex circuit system design and cost, while NB-IOT uses authorized frequency bands and communication technology requires us to charge a certain fee.
In short, in the new wave of IoT development, only by landing projects first can we have a chance to win a step in front.
LTE-M is only for 4G networks, whereas NB-IoT can be deployed on both 2G (GSM) and 4G (LTE) networks. However, NB-IoT employs DSSS modulation, which calls for specialized gear, whereas LTE-M is already compatible with the current LTE network. Both are expected to be supported by 5G.
Explanation: A) Data link layer is utilized in Internet of Things devices for wireless connections.
Transportation IoT Telematics Solutions Telit offers the essential parts and services that enable smart city IoT solutions spanning the operations and functions of the city and providing reliable data in real-time.
In contrast to phone tethering, we discovered that using a dedicated 3G/4G LTE hotspot is a more dependable method of streaming. A significant factor in this was the reliable cellphone service and Ethernet hardwiring. Real-time bandwidth and data use monitoring is convenient.
