Do you know the advantages and disadvantages of IOT?

The era of data transmission is entering our life at a very fast speed, and safe and reliable data transmission is the basic condition to achieve the goal. automatic probe station In most cases, 3G, 4G and GPRS are used to transmit data, which leads to high costs and affects the popularity of iot services, so NB-IoT technology comes into being.

NB-IoT(Narrowband Cellular iot) skills choose the principles of ultra-narrowband, repetitive transmission, simplified network protocols, and gain carrying capacity for low-power wide-area iot by sacrificing certain speed, latency, and mobility instincts. private 5g NB-IoT has the following advantages:

Mass data access: Under the same base station coverage economic conditions, NB-IoT skills are 50 to 100 times the number of other wireless technology skills, and each sector can effectively ensure network access to 100,000 terminals.

Low power consumption: For many battery-powered devices and occasions, the low power consumption characteristics of NB-IoT can greatly improve battery life from a few months to several years, so the inconvenience caused by frequent battery replacement is greatly reduced.

Super coverage :NB-IoT has 100 times more coverage than LTE. This can not only meet the need for large coverage in sparsely populated areas, but also for underground applications that require deep coverage.

Low cost: NB-IoT does not need to rebuild the network, private lte and both RF and antenna can be heavily reused due to cellular network technology on licensed frequencies. In addition, NB-IoT's low power consumption, low bandwidth and low speed also reduce the cost of chips and modules.

The disadvantages of nb-IOT are also obvious:

Less data transmission: Based on low power consumption, NB-IoT can only transmit less enterprise data;

High communication costs: In addition to the price of NB-IoT communication modules, operators will also charge operating costs;

Immature technology: although NB-IOT technology is widely used, in the actual application process, various failures often occur, resulting in communication interruption;
