This makes it a flexible solution for expanding internet access in urban areas where time and space constraints make traditional cable deployment challenging.

Limitations of 5G

Signal Range and Penetration Issues: 5G, particularly millimeter-wave (mmWave) frequencies, has a limited range and struggles to penetrate buildings and physical obstructions. This can be a challenge for indoor use, where signals may weaken or drop altogether.

Network Congestion: In densely populated areas, 5G networks can become congested, reducing speeds during peak usage times. This can be a disadvantage for MDUs where many tenants may be using the network simultaneously.

Dependency on Proximity to Towers: For the best performance, users need to be close to a 5G tower or small cell. This makes 5G a less viable option in remote or sparsely populated areas where cellular infrastructure may be lacking.

Fiber-optic internet and 5G wireless networks each have unique strengths, making them suitable for different needs in MDUs (Multiple Dwelling Units) and business environments. Fiber-optic internet offers extremely high speeds, often surpassing 1 Gbps, with very low latency, making it ideal for real-time applications. It requires a physical infrastructure investment but provides stable and reliable connectivity in areas where fiber is available. Although it has a higher upfront cost, fiber's long-term reliability and durability often make it a worthwhile investment.

On the other hand, 5G wireless networks can deliver high speeds, up to 1 Gbps or more under ideal conditions, with low latency. Its key advantage lies in its quicker deployment due to the wireless nature, though it relies on nearby towers. 5G's coverage can be broad, but it tends to be less effective indoors or in remote areas. While 5G may have lower initial setup costs compared to fiber, the ongoing costs can vary, especially when considering data plans. It may also be more susceptible to service fluctuations due to network congestion or physical obstructions.
