Dynamic Spectrum Sharing in Wireless Network

Dynamic spectrum Sharing (DSS) is a new emerging technology that allows flexibility to mobile operators for switching between low, mid, and high-band frequencies. It allows both 4G and 5G to share the same spectrum. In this article we are going to learn about the definition of DSS, how it works, all terminologies related to it, what are its disadvantages and disadvantages, and why it is making people’s lives easier.

The full form of DSS is Dynamic Spectrum Sharing. DSS is an emerging technology that provides mobile operators with flexibly allocated spectrum across low, mid, and high band frequencies and dynamically switches between LTE and 5G. This technology allows efficient use of the spectrum. In Dynamic Spectrum Sharing (DSS), the spectrum is intelligently switched between 4G and 5G depending on its requirement. DSS technology allows cellular networks to serve 5G service without physically upgrading their radios

How Dynamic Spectrum Sharing Works?

There are various steps that happen while dynamically allocating spectrum in a wireless Network. First is the allocation of spectrum, In earlier times the 4G and 5G networks have different spectrum frequencies. With DSS technology the available spectrum is dynamically allocated to different technologies based on demand and usage. DSS uses the Software-Defined Radio (SDR) technology, which allows the behavior of communication devices to be redesigned through software updates. SDR allows the required allocation of spectrum without changing any hardware component.

Why DSS is necessary?

We can understand this through an example, if any person(operator) wants to upgrade his 4G mobile network into a 5G mobile network then DSS allows smooth migration of spectrum resources from one technology to another. This technology migration does not require any changes in hardware or existing infrastructure. For the development of any country or region, it is very necessary to have a good network connection because it facilitates communication and collaboration easily. DSS is also Cost-effective and efficient.

Advantages of Dynamic Spectrum Sharing

• Speed: 5G networks are faster than 4G networks. It becomes easy with DSS technology to update from 4G to 5G as it does not require much effort or any changes in infrastructure. So, DSS technology helps 5G reach more users faster than traditional radio hardware upgrades.
• Increase in Performance: The increased speed of any device is directly proportional to the high-speed network connection. DSS technology also helps in increasing performance along with speed.
• Cost: Enabling 5G through DSS helps commercial carriers reduce the cost of upgrading their service. That’s why DSS technology is more widely preferred by organizations and industries for upgrading their network services.

Disadvantages of Dynamic Spectrum Sharing

• Resource Overhead: DSS introduces additional resource overhead on the network infrastructure. This increases the complexity of the overall infrastructure. This overall increase in resources may reduce the efficiency and performance of the network.
• Security: Dynamic spectrum sharing introduces additional concerns of security. The reformation inside systems through software updates raises concerns about potential vulnerabilities.
• Complexity of Implementation: Implementing DSS technology requires software-defined radio (SDR) technology which has a complex algorithm for real-time spectrum management. The complexity of this system increases challenges at many steps during implementation.

Some Terminologies Related to Dynamic Spectrum Sharing (DSS)

• Software-Defined Radio (SDR): A software-defined radio (SDR) system is a radio communication system that uses software to process various signals. Technology that allows the behavior of communication devices to be reframed through software updates which enables flexibility in spectrum utilization.
• Cognitive Radio: Cognitive radio is a type of wireless radio communication system that can automatically change its transmission parameters based on the requirement of the user and the availability of spectrum.
