The latest wireless standard is the fifth-generation network. What makes it exceptional is its service categories, including — eMBB, URLLC, and mMTC.
The categories can make the 5G network stand out in the market, among others. In addition, these categories enable virtual connectivity between people, machines, things, and devices. You should know how mobile networks evaluate and the way 5G supports smarter cities & future advancements.
What are eMBB+, URLLC and mMTC?
eMBB (Enhanced Mobile Broadband), mMTC (massive Machine Type Communication), and uRLLC (Ultra-Reliable Low Latency Communication) are the three important use case classes for fifth-generation networks. Networks of Fifth Generation have to meet the requirements to enable current & future use cases in mobile telecoms.
The Evolution of Mobile Networks:
Every network generation offers new services to cellular communication systems. People are using the 5G mobile network standard currently. Mobile networks evaluate from 1G to 4G. However, this generation is the most capable air interface wireless communication standard. It can quickly open new realms for the mobile ecosystem at low latency.
The Fifth Generation Mobile Network (5G):
With the help of the foundational technologies made by the fifth generation, it is possible to connect everything. Its focus is bringing the most reliable network at low latency for communication between devices and humans.
5G wireless technology is famous for its quick data speed at multi-Gbps. The advent of this network offers lightning speed to cellular communication. Regarding reliability, the fifth generation network has improved many times more than the previous 4G one.
Due to the massive capacity of the network, 5G lets us realize the Internet of Things (IoT). The entire world is updating itself to be involved in a smarter environment. In this case, IoT technology is exceptional. The fifth generation is wireless technology supporting IoT applications.
If a comparison is done with its predecessors and the 5G network, it can be said that the 5G network offers a uniform experience to the users. Therefore, you can experience a substantial rise in devices that you can interlink over 5G networks. As a result, the number of users enjoying 5G network services is increasing.
What is the role of eMBB, URLLC and mMTC in 5G networks?
These set up the building blocks for 5G networks to provide high-speed mobile broadband more than 10 Gbps and reliable communication at low latency.
While these networks are ultra-fast mobile broadband services, these can solve different use cases for the flexibility provided by the 5G New Radio technology.
These support millimeter frequencies (over 6 GHz) and sub-1 GHz bands. Various network characteristics can be used by them for facilitating use cases with various requirements.
If the network supports sub 1 GHz frequencies, it will address use cases with the need for low bit rates & low-powered devices. But if it supports over 6 GHz frequency bands, this network will provide solutions for fixed wireless scenarios where devices consume a lot of power. The outcome may be high data rates and ultra-low latencies.
What use cases can eMBB, URLLC and mMTC support?
The new networks are the evolution of 4G LTE, LTE-Advanced, and LTE-Advanced Pro networks. Their design allows these to support new enterprise-level use cases and support the regular use cases, which are still supported by 4G, 3G, and 2G networks already. 2G GSM, 3 G UMTS, and 4G LTE are the pre-5G networks. All these previous networks can deliver mobile data, voice calls, and text messaging services. These use the essential network capabilities depending on what the customer does.
Flexible bandwidth may be used through carrier aggregation by the network based on high-speed data requirements to accommodate higher data rates. It is why eMBB, uRLLC, and mMTC are important. These allow 5G to cover many use case types. Industry requirements for the future & already available use cases ( supported by mobile networks) are covered by the three use case categories.
We have given an overview of them.
5G eMBB, URLLC and mMTC:
The presence of these categories makes the network perfect for smart utilities, smart cities, virtual healthcare systems, digitized logistics, and industrial IoT.
5G eMBB:
People first learn about the 5G network’s benefits from this category. It can offer excellent internet access even under harsh environmental conditions. With higher data bandwidth, you can get the broadband speed at a gigabit level.
As 5G’s most potential customers, we assume super-fast mobile broadband speeds. Therefore, it is an obvious use case that can be related to even today. We know the importance of high-speed broadband services and most of us explored 4G LTE network’s capabilities as home broadband.
It is 5G, because of which the speed of mobile broadband has gone to another level. Hence, the highest speed can be expected at over 10 Gbps. However, these are virtually theoretical because any network can create a speed this amount maximum in ideal conditions.
But people must experience loss, which a phone signal must endure (signal fading). The network is usually distributed to a lot of people. As a result, the speed per person is decreased. The 5G data rates in real life are considerably lower than the 10 Gbps.
A high data rate is necessary for eMBB, and 5G networks can deliver this even working together with 4G LTE networks. Its combination with URLLC and mMTC benefits new networks because these enable wireless networks to fulfill their needs. The three categories can solve IoT and mission-critical healthcare, defense, and industrial projects.
It is helpful in the following cases:
- Good indoor connectivity among many devices in populated areas
- Consistent user experience with comprehensive network coverage
- Real-time communication and connectivity
5G URLLC:
It refers to ultra-reliable, low, latency communication. People use this category type when they need a 99.99% reliable connection to provide low latencies of one millisecond or below. In this case, the high data rate is not a big concern. Instead, its major target is reliability and connection speed at low data rates. Fifth-generation networks operate a lot of frequency levels like high, mid, and low-frequency bands.
You can experience improved performance, such as lower latencies or enhanced data rates from higher frequencies. Suppose the self-driving vehicle is the use case. Therefore, real-time communication is essential for the connection between the network & vehicle. It indicates that latencies are very low. Different use cases are supported by latencies of 1 millisecond or below. Examples of some use cases are self-driving cars, mission-critical applications, industrial automation, etc.
It features:
- Low latency below the 4-millisecond range
- End-to-end latency between the device & base station – around 5 milliseconds
- 99% reliability
- End-to-end data security
5G mMTC:
It stands for massive machine-type communication. This category is compatible with huge device connectivity in IoT activities. Non-human-type communication models are used in this category. Schemes of this category are different from those used in traditional human-type communication. Therefore, no collisions are seen. Its use cases utilize small packet data transmission techniques. In addition, it offers a combination of random access & scheduling strategies.
It is the Massive Machine Type Communication that needs the network for supporting the billions of low-cost, low-powered devices’ mass deployment. It is an important use-case category that a foundation needs for the digitization of several industries via cellular IoT technologies. Smart meters are one of the instances which don’t need real-time communication. Therefore, delaying some seconds won’t create a problem. They can transmit text-based data at low data rates.
Conclusion:
eMBB, URLLC and mMTC are the 5G service categories that develop smart systems to plan farming, transport safely, remote patient monitoring, digitized logistics, smart grid, and smart traffic management system. So, we can say clearly that 5G is the best.
