What are the challenges in 5G technology :
There are many challenges to address when we move towards 5G standard which demands much higher data rate, ultra low latency, high reliability and security. As we know, fourth generation wireless communication technology LTE and LTE advanced has already been deployed all over the world. 5G – the fifth generation wireless technology requires a new standard to support ultra fast, low latency services to customers.Let’s take a look on major challenges in 5G technology design, development and implementation stages.
5G – Technology Challenges
1. Frequency Bands :
Current LTE system operates with more than 50 frequency bands which are below 3.6 GHz range. One of the frequency candidates for early deployment of 5G is sub-6 GHz range. Unlicensed spectrum below 6 GHz (600 MHz and between 3.5 GHz and 6 GHz) will be used for first generation of 5G networks.5G NR- New Radio standard for 5G networks are set of frequency bands at sub-6 GHz range and millimeter waves of the RF spectrum. Design of hardware at millimeter waves are much complex than low frequency range.In order to ensure interoperability of devices across different countries and regions, it has to supportmulti-bands. Addition of more frequency bands increases the device complexity.Lack of coordination of 5G frequency bands across different regions could cause trouble to mobile device manufactures.
2. Huge Data Volume :
As the technology advances, the data volume of each network also increases every year and the trend is growing. Each network has to support huge volume of data since many applications capable of high resolution video calling, live streaming, downloading etc…
The new media trend is towards video standard and there is huge demand for video contents compared to conventional text form. Multimedia gaming, augmented reality (AR) and virtual reality (VR) applications needs high speed network for better user experience.

3. MIMO Technology :
Complex MIMO antenna arrays will be used to deliver high speed data to individual users. The idea of MIMO is to increase number of transmitting antenna at the base station and mobile device (UE) to maximize the data transfer by simultaneously sending and receiving. MIMO technology requires complex algorithms and device capability at both base station and user equipment.

In order to avoid transmission power wastage, new generation wireless transmission technology will usebeamforming method to efficiently transmit data to user devices. Compared to conventional base stations,beamforming technology will locate the user’s location precisely and transmit signals to that direction usingsophisticated antenna array system.Base station’s operating power can be significantly reduced by beamforming concept. However, beamforming is acomplex task to locate each devices under a particular cell and it needs high level processing at basestations.
4. Device to Device Communication :
D2D communication is new concept to enhance mobile connectivity by using one mobile device as data hub forother devices which can’t access the base station signal. Device to device communication is considered one ofthe efficient mode of communication during emergency situation (like natural disasters) where connectivity islimited or absent. However, complex data transmission protocols required to implement D2D communication.
5. Ultra low Latency Service:
Mission critical applications and self driving cars require ultra low latency services to ensure smooth
operation. Any delay could cause unexpected and devastating results in mission critical applications. Latency less than 1 millisecond need to be achieved to satisfy medical applications like remote surgeries.
