What are the similarities and differences between NB-IoT DTU and GPRS DTU

GPRS DTU and NB-IoT DTU are both DTU, so what's the difference between them in daily use? First of all, conceptually, GPRS DTU, as the wireless transmission terminal of the Internet of things, uses the GPRS network provided by operators, which can provide users with long-distance wireless data transmission function. NB-IoT DTU is also a kind of wireless transmission terminal of the Internet of things, which uses the NB-IoT network provided by operators. NB-IoT network is built on cellular network and consumes only about the bandwidth of 180kHz. It can be directly deployed in GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrade.

So what are the similarities and differences between GPRS DTU and NB-IoT DTU in other ways?

What they have in common:

1. GPRS DTU and NB-IoT DTU, as DTU of different network systems, have the same working principle and function, and both realize the two-way transparent transmission of data between the industrial equipment and the remote server.

2. The application fields are roughly the same, and even can be switched seamlessly. Both GPRS DTU and NB-IoT DTU are suitable for industrial fields that do not require high transmission rates.

Differences:

1. NB-IoT DTU has a better market prospect. GPRS has been around for a long time and is facing phase-out in many foreign countries and regions. NB-IoT DTU has a better future.

2. NB-IoT DTU has stronger linking ability. For example, if the same base station is used, NB-IoT DTU has 50-100 times more equipment access than traditional GPRS DTU. In practical applications, the advantage of the number of access devices plays an important role.

3. NB-IoT DTU has lower cost. At present, Shandong Telecom has achieved 99% of the NB-IoT network coverage, and this trend is expanding to the whole country. The low cost of NB-IoT DTU is reflected in that it can share infrastructure with traditional cellular networks and does not need to be rebuilt; in terms of fees, NB-IoT costs only about 30 yuan a year.

4. NB-IoT DTU has stronger network coverage. The indoor coverage ability of NB-IoT is very strong, which enhances the 20dBm gain than GSM, and correspondingly increases the coverage area by 100 times compared with GPRS. The enhancement of network coverage has great advantages in the deployment of rural areas, factories and underground sites.

5. NB-IoT DTU has lower power consumption. Ultra-low power consumption is very important in industrial applications. NB-IoT has lower power consumption than GPRS, and its battery can stand by for 5-10 years without replacement. In some places where batteries can not be replaced for a long time, NB-IoTDTU:www.top-iot.com/index.php?m=content&c=index&a=lists&catid=12 can be said to be an excellent choice.

At present, NB-IoT is developing rapidly and has a huge development prospect, and due to the rapid development of smart city, smart home, self-driving and other fields, and the sharp increase of Internet of things devices, Internet of things devices based on NB-IoT will certainly shine in the future.
