Introduction

After initial lab tests showed promise for teh emerging G.fast technology, British Telecom’s Openreach announced further testing in two pilot locations in the UK. At the same time, BT unveiled a bold vision to deliver 500Mbps to most of the UK within a decade with G.fast starting in 2016/17. BT did specify that the pilots needed to succeed.

Highlights

  • BT is one of many operators testing G.fast, but has been the most prominent one to disclose the results of its lab trials. The outcome of its field trials in Huntington and Gosforth will be extremely revealing not just for BT but for other operators also considering G.fast.
  • Due to G.fast's current limitations, BT would have to move its newly installed FTTC nodes at considerable expense to within 100 meters of the customer in order to get 1Gbps (or a little, but not much, further out for 500Mbps).
  • The key objective (and key to widespread G.fast deployment globally) will be for these field trials to prove that G.fast can deliver 200-300Mbps economically with FTTC nodes at BT’s existing locations, until they can be relocated closer to customers for maximum G.fast speeds.

Features and Benefits

  • Relates BT's G.fast deployment announcement and trials and provides context in terms of drivers.
  • Identifies key issues required for BT's trials to be successful and for widespread global G.fast deployment.

Key questions answered

  • What did BT announce about its G.fast trials and deployments?
  • Why is BT going ahead with G.fast even though it is still being tested?
