What are the advantages of NB-IoT technology?
In the field of Internet of Things, 5G is undoubtedly one of the hot topics. However, before 2020, 5G large-scale applications, no one hopes, no equipment manufacturers will think that 5G can be quickly deployed. In the 4G era, everyone was driven by Qualcomm chips and standards. If you can find the 5G era that can bypass Qualcomm and not have to die, the NB-IoT narrowband Internet of Things is the first to make a move.
NB-IoT can get a certain degree of attention, so there must be its merits, what is the advantage of NB-IoT?
As a technology used in low-rate services, the advantages of NB-IoT are not hard to imagine:
1. Strong link: In the case of the same base station, NB-IoT can provide 50-100 times more access than existing wireless technologies. One sector can support 100,000 connections, supporting low latency sensitivity, ultra-low device cost, low device power consumption, and optimized network architecture. For example, limited by bandwidth, operators only open 8-16 access ports for each router in the home, and a family often has multiple mobile phones, laptops, and tablets. In the future, it is necessary to realize the whole house intelligence. The need for networking across hundreds of sensing devices has become a daunting challenge. And NB-IoT is enough to easily meet the needs of a large number of devices in the future smart home networking.
2, high coverage: NB-IoT indoor coverage is strong, 20dB gain than LTE, equivalent to an increase of 100 times coverage area. Not only can it meet the wide coverage needs of rural areas, but also for applications such as factory areas, underground garages, and manhole covers that require deep coverage. Taking the manhole cover monitoring as an example, in the past, the GPRS method required an antenna to be extended, and the vehicle was extremely vulnerable to damage. The NB-IoT can solve this problem as long as it is properly deployed.
3. Low power consumption: Low power consumption is an important indicator for IoT applications, especially for equipment and occasions where batteries cannot be replaced frequently, such as various types of sensing monitoring equipment placed in remote areas of the high mountains and wilderness. Like a smartphone, a battery charge for a few years is the most essential requirement. NB-IoT focuses on small data volume and small rate applications, so the power consumption of NB-IoT devices can be very small, and the battery life can be greatly improved from the past few months to several years.
4. Low cost: Compared with LoRa, NB-IoT does not need to rebuild the network, and the radio and antenna are basically multiplexed. Taking China Mobile as an example, there is a relatively wide frequency band in 900MHZ. Only a part of the 2G frequency band needs to be cleared, and the simultaneous deployment of LTE and NB-IoT can be directly performed. Low speed, low power consumption and low bandwidth also bring low cost advantages to NB-IoT chips and modules. The module is expected to cost no more than $5.
Today, NB-IoT has been gradually applied to various fields, such as smart water meter, smart farm, smart home, fire fighting and so on. Concox's own NB-IoTGPS locator. If you want to learn more about NB-IoT products, at https://www.iconcox.com/about/contact_us.html
