Larger and Faster
For the quality of voice services provided by mobile network operators, a round-trip delay (latency) of 100 milliseconds or less usually falls in the acceptable range. If a delay lasts longer than 100 milliseconds, it can be perceived by users.
On the other hand, video services require a faster response time than voice services. Users will find that the service quality is deteriorated if a video response time exceeds 10 milliseconds. The delivery of quality video service often requires high bandwidth.
In the IoT era where virtually everything can be connected to the network, the focus of future network is on reducing the latency. For augmented reality and IoT-based services, a latency of 1 millisecond or less will be expected to provide quality services. If network latency exceeds 1 millisecond, this will compromise dynamic growth of the Internet of Things, compared to the existing technologies.
To meet the extreme traffic demands in future networks, for example, the growing popularity of 4K video, much more spectrum will be needed. According to the recent research by Nokia, traffic volume is expected to increase up to 10,000 times by 2020. To handle higher traffic in a larger bandwidth, future network technologies will need to enable peak data rates “exceeding 10 Gbps, with user data rates greater than 100 Mbps even under high load conditions or at the cell edge” (Nokia Solutions and Networks, Looking Ahead to 5G: Building a Virtual Zero-Latency Gigabit Experience).
Today, as a mobile network user, you need to choose one of the pricing plans that your mobile network operator offer. With a limited number of offerings, you do not have the flexibility to choose the most suitable service for you.
However, this will change in the future networks. In the IoT era, you will need not only voice and data services but different types of connectivity for numerous devices that you own. That is, the Internet of Things will have a profound impact on the way networks evolve, creating new service requirements that have not been considered before. These requirements will be a key driver of network evolution and lead mobile network operators to accommodate user-oriented services.
