5G is going to be the new generation of engineering wireless services and it’s going to mark its presence all over the world. 5G, which stands for Fifth Generation, is going to be all about way faster speeds, faster data transmission and even broader coverage. This will change the landscape of how we do things today. However, there are some challenges with the successful implementation of the 5G network design. So let’s understand what these challenges are:
1. Hardware for high-frequency bands is complex to make
The hardware to support high-frequency bands is the most difficult to develop. The 5G standards require that the antenna elements have a bandwidth of at least 1 GHz and transmit power levels of several hundreds of megawatts. This is because they must be able to cover more frequencies than the current 4G systems can. In addition, they need to be able to handle much higher data volumes, which is also difficult because of the large size required for each component. To achieve 5G, carriers need to build new equipment for the high-frequency bands (30 GHz and above). This will require a lot of R&D by the telecom industry, which is not easy to do because it involves other industries too. The cost of equipment will be high, so even if there is demand, it may not be profitable enough to be done in the long run.
2. Huge Data Volume
The amount of data that can be transferred over a single channel during a call is likely to increase significantly with 5G technology, as well as its capacity to handle multiple channels simultaneously. According to the US Federal Communications Commission (FCC), 5G will require more than 100 times more spectrum than the current LTE networks do, which means that some countries may have difficulty finding enough space for all this new gear if they want their own 5G networks operating soon. Additionally, in order to achieve this level of performance, carriers will have to increase their bandwidth by a large amount compared with that of 4G LTE. This means more deployment is required and more cost is incurred by each carrier.
3. MIMO Technology
Multiple Input Multiple Output (MIMO) technologies uses multiple transmitters and multiple receivers to improve performance in wireless networks. This means that instead of transmitting data through a single antenna at one time, your device will get multiple signals from different antennas at once, which allows for faster speeds and better coverage. However, the problem is that to ensure that MIMO technology gives its full benefits, it must be backed by really complicated algorithms. These algorithms need to be present both in the equipment that the user has and the base station.
Beamforming is a technique that allows the transmitter to send out narrow beams of data specific to the user after finding their location. For transmitting these signals highly sophisticated antenna arrays are needed. The problem with the beamforming technique is that it significantly reduces the operating power of the base station.
