About
Extunda leads national R&D Projects on 5G wireless communication technology. Extunda invests in cloud-RAN development. The project consists of NFV and SDN software development for cloud-based centralization of the RAN components of base stations for 5G.
Goal
The aim of the project is to develop the first 5G cloud radio access network in Turkey.
Background
The first base station hardware was produced for 2G systems in the 1980s, and since then all 3G and 4G network generations have base station hardware developed and used in remote locations. Today, 4G-LTE and 4.5G networks use base station hardware systems to serve subscribers as well. Due to the nature of network distribution, base stations must be deployed close to subscribers and therefore base stations must be connected to the service operator\'s main network using fiber or xDSL technology.

However, increased consumption of data, reduced revenue from voice traffic, and intense competition between service providers negatively affect the bottom line of operators. Therefore, service operators are looking for ways to reduce investment per subscriber today.
To achieve this, the reduction of CaPEX by opening fewer base stations and similarly the reduction of OpEX by lowering distribution, operation and pre and post launch optimization costs. Cloud RAN technology achieves these CaPEX and OpEX savings by centralizing all base stations in the data center and providing requested services from this central location.
In cloud RAN technology, all functions of the base station are performed in software running in the cloud. The cloud consists of separate software and hardware clouds. All base stations are created in real time and on demand. Each base station created runs on the same hardware cloud. In addition to the advantages of low cost and ease of use cloud architecture, another important advantage of this system is the ease of trials of new features on the network.

Operators can easily try new features in the central location and do it before and after comparison to decide whether this feature should be deployed on a network. Currently, the duration of a single feature trial is on orders of months. With the 5G cloud, the time will be in the order of days. Therefore, service operators can deploy useful features and quickly improve network coverage and capacity.
Advantages of 5G Cloud RAN
Cloud RAN technology has unique technical and financial advantages.
Basic advantages;
Centralizing all the functions and features of the base station in a central location makes network deployment, troubleshooting, and operation less erratic and faster.
It will be much easier to improve network performance, change base station parameters, and attempt to execute and manage on new network features.
Network operators will be able to manage the performance of all networks together rather than managing the performance of each base station. Spectrum management, traffic management and load balancing will be done faster and more optimally.
The data of the base stations are stored and processed in the data center. Since this data will not be transported over the operator\'s backhaul network, the backhaul capacity will be used to carry the user\'s traffic. Therefore, subscribers will be provided with better, faster and low latency high quality data services.
Access and processing of data will be strictly controlled, as the base stations will operate in the data center under the service operator\'s control. Thus, data security will be higher for cloud RAN.
All smallcell, metro cell and picoceles are connected to the operator\'s core network. Today, the optimization of these network nodes is done semi-independently.
With the cloud RAN technology, the optimization of the entire network will be done together with the smallcells, which will significantly increase the performance of the network.
