What is a limitation of 5g mmwave, despite its high speed? All major TECH COMPANY is now introducing 5G cellular technology in their mobile networks. Businesses should examine not only the benefits of 5G but also the constraints of the limitation of 5g mm wave, despite its high-speed wireless networks.

5G technology provides low latency and high-speed bandwidth, which supports real-time applications and data-rich mobile apps, leading in a superior overall user experience. Now that practically all devices enable 5G with essentially no price premium, 5G should be a prerequisite for all new mobile phone purchases.

There should be no price premium, and all new mobile phone purchases should have a 5G need.

However, while the technology vastly expands 3G, 4G, and LTE cellular infrastructure, 5G has a few Limitations, despite its high speed that organizations should consider before replacing prior generations of wireless technologies.

While cell networks are regularly building new 5G towers and transmitters, proximity will continue to be an issue. To receive the finest 5G connectivity, you must be close to 5G infrastructure. Densely populated urban regions will have higher 5G coverage, but even this will be restricted.

5G largely employs millimetre wavelengths, which are smaller than those used by 3G and 4G and do not travel as far. Despite the fact that the 5G coverage profile is lower, the 5G signal can transport more data. Carriers are constructing a considerably bigger array of antennas to compensate for this restriction.

Beamforming is also utilised with larger arrays to assist the 5G system in overcoming additional barriers by allowing packets to travel several routes to reach a client. Businesses that want to employ beamforming technology should look into their carriers’ 5G coverage maps. Carriers are deploying 5G networks now, with increased coverage in urban regions; 5G network rollout will expand to more rural or distant sites over time.

2. Spectrum and bandwidth

As service providers share more of their radio frequencies across 4G and 5G, spectrum and bandwidth are improving. While carriers continue to expose more of their allocated spectrum to high-speed 5G, the desired performance and low latency of 5G will mostly come from millimetre wave deployments, which will be significantly more limited in distance due to the proximity issue.

Spectrum is an important issue while selecting carriers and equipment. The majority of 5G rollout will occur across current 3G and 4G spectrum, allowing for backward compatibility with older devices.

Network slicing is one way 5G will overcome the bandwidth limits of today’s technologies. Network slicing borrows from the virtualization movement, which has increased data centre density, capacity, and capability by “slicing” up resources in order to share more idle resources and boost overall usage. With network slicing, 5G operators may better use their networks by handling more users and transferring more data at the same time.

3. Rural and remote locations

Rural and isolated areas have seen little change as 5G rollouts have focused on urban areas, but carriers have begun considering fixed 5G solutions for connecting to home Wi-Fi. Rural broadband providers have increased, with Starlink satellite service vying with the dominating HughesNet for rural internet via satellite, but we have yet to see a significant push on rural 5G.

Rural and rural areas are unlikely to obtain 5G service until after most urban construction projects have been finished. While 5G applications abound in industries such as agriculture and mining that require remote access, carriers may find it cost-effective to deliver 5G in some isolated locales.

The economic ROI that a carrier can obtain from a certain geographic location will drive much of the 5G deployment expansion. The 5G golden spot for carriers is when they take 3G and 4G equipment down or minimise their footprint.

4. Security

Both carriers and enterprises are concerned about security. The whole architecture of 5G, particularly in back-end provisioning and handling, allows for improved and more granular security capabilities on the carrier side. Furthermore, like with previous wireless technology transitions, security is primarily handled on the most recent platforms first, so it is believed that 5G would largely bring greater security.

Because it includes new security features, 5G has a different security paradigm than 3G and 4G. The good news for businesses is that much of the deployment will be handled by carriers. However, understanding these new security models will be crucial for enterprises that build network services on top of 5G cellular networks to ensure they are building comprehensive, secure services.

Overall, businesses are in a better position than ever to take advantage of the prospects presented by 5G, as the benefits can clearly boost mobile communications. However, the actual change must consider not just the rewards, but also the problems.

Despite its network performance improvements, mmWave 5G has significant coverage and range limits when compared to Sub-6 GHz 5G and 4G technologies. As a reminder, higher-frequency electromagnetic waves cannot travel long distances and are more sensitive to physical barriers.

To fully realise the promise of fifth-generation networks based on millimetre wave specifications, hundreds to thousands of smaller cells must be placed in a single area to increase and improve network coverage. It should be noted that the Sub-6 GHz 5G network does not have this stringent infrastructure requirement.

The following are the drawbacks and limitations of 5G networks based on the millimeter wave specification

• Because of the requirement to construct numerous smaller cells in strategic areas to achieve maximum coverage, deploying mmWave 5G networks is inherently more expensive than deploying 5G networks based on the sub-6 GHz specification.

• With some tweaks, sub-6 GHz can utilise the existing infrastructure of 4G networks. Furthermore, because the sub-6 GHz frequencies may travel vast distances, the space between these towers is larger or wider.

• As a result, of the two 5G NR specifications, Sub-6 GHz networks are more practicable and appropriate for rural areas with populations and structures dispersed across a big geographic area. mmWave 5G networks are more suited to densely populated areas.

There is also an aesthetic issue to consider. Placing multiple smaller cells in every corner of a street or segment of a block can have an impact on the beauty of a natural environment or the aesthetics of significant man-made structures.

• Another disadvantage is incompatibility. Not all 5G devices are created equal. Some of these devices would only work on networks operating at less than 6 GHz. Consumers should investigate the underlying radio technology in the products they intend to purchase. Devices fitted with the millimetre frequency requirements would also consume a lot of power, especially when coupled to a fifth-generation network. As a result, in particular use-case scenarios, it is preferable to run on 4G or 3G networks.
