When talking about the Internet of Things, you should hear the term cellular network a lot. What is a cellular network? What role does it play in IoT?
What is a cellular network?
Cellular network technology is known as a mobile network and lte cat 4 can be further categorized into analog cellular networks and digital cellular networks, which mainly exist distinguished by the way in which they transmit management information. The reason for the name is mainly business due to our network can be covered by the various communications industry base station signal coverage presents a hexagonal shape, shaped like a honeycomb, so we are called cellular network.
Cellular network consists of mobile stations, base station subsystems and network subsystems. A mobile station is a network terminal device such as a cell phone or some kind of cellular industrial control device. These base station subsystems include mobile base stations, wireless transceivers,lte cat1 private networks, and wireless digital devices. This subsystem can be seen as a converter between the wireless network and the wired network.
Cellular networks provide the backbone for many of the things we know and love, allowing us to access the Internet, ride public transit, contact friends, shop, watch videos, and more. In addition to well-known personal applications, cellular networks play a vital role in many IoT applications and are constantly evolving.
What is the role of cellular networks in IoT?
In IoT, a large number of applications do not actually require high data rates, but have more stringent requirements on terminal power consumption and cost. And because these terminals are so numerous and widely distributed, they require extensive wireless networks to provide complete coverage, such as networked street lights, smart parking meters and smart water and electricity meters, as well as countless industrial and agricultural applications, which have been dramatically changed by cellular networks.
Cellular network system has the advantage of high coverage and high reliability, in the outdoor coverage can be achieved through the realization of more than 99%, and the development of infrastructure and education facilities are well-built, high reliability, and trustworthiness is likewise high, compared with other communications information technology enterprises, the cellular technology in the distance, coverage, stability, etc. have their own certain economic advantages, there can be no formation of a complementary.
Advantages of cellular networks?
Because cellular IoT uses existing mobile networks while the already existing extensive coverage. One can also handle the distribution of devices across countries and cities. This is necessary for any information-critical iot project, especially for monitoring properties, mobility and other technology company activities.
It's important to remotely manage, regularly test and monitor any physical device involving cellular IOT devices. Regardless of geographic location, you can use an online IOT system to remotely monitor and troubleshoot connected devices. This advantage means that service technicians can be notified without having to search for anomalies in each system. As a result, cellular connectivity eliminates interruptions and significantly reduces the costs associated with field service.
Personal networks and protection tools, in order to prevent illegal disclosures, every IoT application requires security protocols. This is especially important for all sensitive data tracking devices such as medical applications or fraudulent applications. To add a layer of protection for users, networks and data, cellular IoT devices can use private network technologies such as VPN, APN and IPsec protocols.
