AT&T 5G Launch A Look Back at 2018

AT&T’s 5G Network Rollout in Late 2018

AT&T’s 5G network rollout in late 2018 marked a significant milestone in the evolution of mobile technology. It was a pioneering step in bringing the promise of ultra-fast speeds and low latency to consumers and businesses. This rollout was characterized by its phased approach, focusing on specific markets and utilizing a combination of technologies to achieve initial 5G capabilities.

Timeline of AT&T’s 5G Network Launch

AT&T’s 5G network launch was a gradual process, starting with limited availability in select cities and expanding over time.

• October 2018: AT&T launched its first commercial 5G network in 12 cities, including Atlanta, Dallas, and Houston. The initial deployment focused on fixed wireless access, using 5G technology to provide high-speed internet to homes and businesses.
• December 2018: AT&T expanded its 5G coverage to include more cities, including Los Angeles, San Francisco, and New York City. The company also began offering mobile 5G services in select areas, using its existing 4G LTE network for coverage and 5G for speed enhancements.

Technologies Used by AT&T for its Initial 5G Deployment

AT&T’s initial 5G deployment utilized a combination of technologies, including:

• mmWave: AT&T used millimeter wave (mmWave) spectrum, specifically the 28 GHz band, for its initial 5G deployment. mmWave offers extremely high bandwidth, enabling download speeds of up to several gigabits per second. However, mmWave signals have limited range and are easily blocked by obstacles, requiring dense network deployments.
• Sub-6 GHz: AT&T also used sub-6 GHz spectrum, specifically the 3.45 GHz band, for its initial 5G deployment. Sub-6 GHz spectrum offers a wider range and better penetration compared to mmWave, but it also provides lower bandwidth and speeds. AT&T used sub-6 GHz spectrum for its mobile 5G services, leveraging its existing LTE network for wider coverage.
• Dynamic Spectrum Sharing (DSS): AT&T utilized DSS technology to enable its 5G network to operate on its existing LTE spectrum. DSS allows for simultaneous use of the same spectrum for both 4G and 5G, effectively increasing spectrum efficiency and accelerating 5G rollout.

Initial Challenges Faced by AT&T in Launching its 5G Network

The initial launch of AT&T’s 5G network was not without its challenges. The company faced several technical hurdles and market adoption issues.

• Limited Coverage: Initial 5G coverage was limited to specific areas within select cities, primarily in dense urban environments. The limited range of mmWave technology restricted coverage to areas with high population density and line of sight.
• Device Availability: The availability of 5G-compatible devices was limited during the initial rollout. This limited the number of consumers who could access AT&T’s 5G network.
• Network Capacity: The limited availability of 5G spectrum and the high demand for 5G services led to network congestion and slower speeds in some areas. This was particularly evident during peak hours and in high-traffic areas.
• Consumer Awareness: There was a lack of consumer awareness regarding the benefits of 5G and the availability of 5G services. Many consumers were not aware of the difference between 4G and 5G, and they were hesitant to adopt the new technology.
