REPORTS EXECUTIVE SUMMARY
Gfast Rollout Starts With Amendment 3 Chipsets

With governments mandating minimum broadband speeds and users investing in Ultra HD TVs and the latest gadgets, we are seeing rapidly-growing demand for higher-speed fixed broadband. Small- and medium-sized businesses (SMBs), which are increasingly using cloud-based services, are also using fixed broadband lines for their main Internet connection or as a backup connection. Mobile data offloading to local WiFi networks sends further bandwidth through fixed broadband links.

Gfast's rollout has been delayed while silicon vendors work on second-generation chipsets (that benefit from lessons learned in initial trials) and implement new features defined in Amendment 3, which was agreed in April 2017. These new features include 212 MHz bandwidth operation, support for coax and dynamic time assignment (DTA). In the meantime, there have also been developments for VDSL, including VDSL 35b, which supports bandwidths up to 300/400 Mbit/s, and trials of long reach the ADSL.

All the pieces are falling into place for the rollout of Gfast during 2018 and into 2019. The success of Gfast now depends on the real-world performance achieved and the relative attractiveness of alternative solutions, including FTTH and fixed wireless using 5G. As systems based on second-generation Gfast chipsets are moving into production, semiconductor vendors are already working on their third-generation solutions. These will include further enhancements to Gfast performance, lower power consumption per line and greater integration. Taken together with the growing number of Gfast systems that should be available during 2018 and into 2019, we should see a significant reduction in the cost of delivering gigabit services over existing copper infrastructure.

We expect the rollout of Gfast systems and services based on the latest chipsets to start in 2018 and ramp during 2019. Gfast Rollout Starts With Amendment 3 Chipsets details and analyzes chipsets from the leading vendors in this important market as network operators plan the rollout of Gfast and the latest the VDSL2 services. The report profiles the vendors and reviews specific chipset families, identifies the key features and highlights the advantages they hold for system developers and service providers.

Mobile and fixed-line broadband traffic is growing steadily, as shown in the following excerpt. Connected homes have an increasing number of connected devices, and many connected devices support high-bandwidth applications. When the first broadband connections were made to homes in the late 1990s most were servicing a single PC. Now most TVs are connected to the Internet and each family member has a mobile phone, a computer or a tablet, with many having all three. Most wireless service providers, and the latest handsets, support WiFi offloading, which adds mobile data to the fixed broadband traffic. The home may also have many connected devices, such as burglar alarms and surveillance cameras.
