A small tower and 5G cell site costs $30,000–$50,000. The cell site will also require commercial power and batteries if the wireless network is expected to work during a power outage.
Does 5G use more data than 4G? The short answer is no – 5G doesn't use more data than 4G. If you download a file or load up a web page, it will take exactly the same amount of data to do that over 5G as over 4G. Yet data use on 5G often will be higher.
These include higher-quality FaceTime, high-definition content on Apple TV, Apple Music songs and videos, iOS updates over mobile, and automatic iCloud backups. With this setting, your iPhone can automatically use 5G instead of Wi-Fi when Wi-Fi connectivity is slow or insecure on a network you visit occasionally.
The growth of 5G networks doesn't mean 4G is going away. Mobile carriers will use existing 4G LTE networks to provide their customers' cell service well into the next decade. 5G networks will work with 4G — not outright replace it. The upshot is that 5G-capable cell phones will still use 4G technology.
E-UTRAN New Radio - Dual Connectivity (EN-DC) is a technology that enables introduction of 5G services and data rates in a predominantly 4G network. UEs supporting EN-DC can connect simultaneously to LTE Master Node eNB (MN-eNB) and 5G-NR Secondary Node gNB (SN-gNB).
A more realistic 5G deployment for rural areas (when it eventually happens) will be with transmission in long-range, low-bandwidth frequencies or what are known as the low and mid bands (600 MHz to 900 MHz and 2.5 GHz to 4.2 GHz, respectively). This will require fewer cell towers since signals can travel a few miles.
In Ookla's Q1 Speedtest® Global Index Market Analysis United States report measuring nationwide network performance, T-Mobile took the top spot for Overall Speed, Highest Consistency, Fastest 5G Speed and Best 5G Availability. Since the Q4 2021 report, T-Mobile's overall median network speed increased 30%.
During the two-week delay in deploying new 5G service, safety experts determined that 5G interference with the aircraft's radio altimeter could prevent engine and braking systems from transitioning to landing mode, which could prevent an aircraft from stopping on the runway.
Whereas 5G can have downlink speed up to the scale of 20 Gbps and 10 Gbps uplink, practical speed measured on Fiber cables is 100 Gbps. One major drawback with using 5G technology is that each cell/station can have expanse up to a few 100 meters while Fiber provisioned signal can reach up to 70 Kms.
“Huawei continuously supports South Africa to build its 5G networks. So far, over 2 800 base stations have been deployed, making it the largest 5G network on the African continent.” US-based broadband testing diagnostics company Ookla recently revealed SA has taken the driver's seat in Africa's 5G race.
