5G FAQ: The 12 Most Common Questions

Jun 2, 2021 | Featured Posts, DAS/5G

1. How does 5G work?

5G operates much like it’s 4G LTE predecessor and often reuses some of the Radio Frequencies (RF or Spectrum) that were used or repurposed from 2G, 3G or 4G LTE. 5G will work together with 4G initially while 5G evolves to better integrate with internet and cloud base services. Some Wireless Carriers will utilize higher RF bands called ‘millimeter waves’ (mmwaves) through small cell on streetlights and buildings. Through Network Densification, Wireless Carriers will provide customers will faster data speed and lower latency.


2. How much does it cost to install 5G?

The  cost to install 5G varies, 5G comes in many different forms as simple as small cells to tower upgrades and can range anywhere from $20,000 to several hundreds of thousands.


3. How are 5G networks installed?

5G networks will co-exist side by side with 4G LTE’s Evolved Packet Core (EPC) as 5G Core evolves into a common multi-access, cloud based platform. Small cells and tower sites will be installed or upgraded into the existing carrier network to support 5G services.


4. Does 5G require a new phone?

The first Samsung 5G phones were released in 2019 and 2020 for iPhone.  If you have an older phone, you will need to upgrade your phone for 5G Services.


5. What are the benefits of 5G?
  • Coverage inside buildings and structures, especially those with areas of poor or intermittent connectivity
  • Increased data speed (up to 100 times more throughput)
  • Increased uplink and downlink speeds
  • Improved latency (device response over wireless) as low as 1 millisecond, as compared with 30 milliseconds on a 4G network
  • Additional cell sites for increased capacity using network densification solutions


6. What are the disadvantages of 5G?

Millimeter (mmwaves) have a higher band radio frequency and are being utilized for 5G signal but do not penetrate buildings well. To address this issue, more small cells and in-building DAS will need to be installed to provide adequate coverage and throughput.


7. Which Cities have 5G?

5G has been rolled out to most Metropolitan areas in the US and Worldwide today.


8. How do I find a 5G coverage map near me?

Each Carrier has coverage maps posted on their website.

9. Is 5G worse than WiFi?

5G can actually be faster than your home WiFi network.  The average speed of US Carriers are about 70Mbps and can theoretically reach speeds of 10Gbps.


10. How is 5G different from 4G?

5G is up to 100 times faster than 4G. There is less latency and capacity for a much larger number of connected devices.


11. How is 5G transmitted?

5G will leverage the Wireless Carrier’s existing tower sites and a network of small cells to provide additional bandwidth and coverage that is needed for 5G speeds.


12. Do I have to worry about 5G radiation?

No.  For all radio frequencies (0 to 300 GHz), international maximum levels are designed to avoid any adverse health effects. See chart below.​​​​ ​​
