Many telecom companies are currently planning their 5G network deployments. However, technical and logistical issues will make rolling out 5G coverage more complex than with earlier generations.
At a glance:
Telecom companies are betting big on 5G. According to a global analysis by consultancy McKinsey, firms will spend over $600bn on the next generation of mobile networks between 2022 and 2025. As of March 2024, 308 operators in 118 countries had launched at least one 5G service, according to the GSA, an industry association.
Expanding public and private 5G networks will support emerging technologies - from autonomous vehicles to edge computing and virtual reality. However, the practicalities of rolling it out are considerable.
Let’s learn about some of the practical and logistical challenges surrounding the network deployment of 5G technology and how they can be overcome.
5G network deployment is significantly more complex than the rollout of earlier generations of mobile networks (such as 4G and 3G).
There are two key reasons for this greater complexity:

Telecom companies will likely encounter several challenges as they continue designing and installing 5G networks. Preparing for these issues will be essential to successfully deploying 5 G.
Around the world, telecom companies are paying enormous sums of money on 5G spectrum auctions. For instance, the four major telcos in the United States spent an extraordinary $100bn on 5G midbands in 2022. Similar spending is being seen elsewhere. Nevertheless, there remains much uncertainty about the potential return on their investment.
5G components and equipment are also very expensive. Prices vary, but according to
TechTarget, 5G macrocells (a core part of network architecture) cost around $200,000 to set up. Individual small cells are priced at around $10,000.
Planning permits remain a major obstacle to 5G network deployment, particularly with the mmWave spectrum base stations. These will need to be installed in dense networks around urban areas - on street lamps, bridges, buildings and so on. However, local planning laws must be navigated in many cities to install this technology. This can delay deployments of 5G public networks.
When planning coverage areas for 5G, technicians and engineers will need to spend much time visiting sites to plan the precise location and position of base stations. Since high-band mmWave 5G attenuates rapidly over short distances and can be disrupted by obstacles such as foliage, engineers must conduct meticulous line-of-sight analysis.
For 5G to offer the promised speeds, a backhaul network that can handle the high volumes of data transmitted from the 5G core network will be required. Therefore, telecom firms may need to invest in expanding fibre optic networks, too - and the cost of fibre optic cabling and installation is often very high.
As telecom companies deploy 5G, they must manage an ever-larger array of hardware and equipment in the field. This must be monitored, maintained, upgraded, and replaced over time. Managing this inventory will be challenging.
Furthermore, since much of this hardware will be in easy-to-access places (such as lampposts), it may be a more likely target for theft, interference or accidental damage than traditional cell towers.
In certain countries, there is a shortage of skilled technicians, engineers and project managers who are essential for network deployment. Recruiting, training and upskilling staff to support 5G network deployment will be critical.

For over 30 years, LuxCarta has provided the telecom industry with maps for every generation of mobile network deployment. We can also provide essential tools to help you deploy 5G networks.
Our RF planner solution uses satellite images from high-resolution sensors. It then uses our proprietary machine learning algorithm to analyze any area you select (from dense urban environments to rural areas), identify terrain, and classify landscape features such as terrain, manmade features and vegetation. Human experts validate this to provide detailed, reliable, easy-to-use 2D and 3D maps.
When it comes to 5G network deployment, technicians, engineers, and project managers at many telecom companies are already using LuxCarta to help with:
