13. New business models for rail connectivity
…some considerations
21/03/2016 13Company Confidential © Real Wireless Ltd. 2016

14. How and when will we see the Gigabit train?
Six targeted questions:
1. What does the mobile industry need to do to achieve the Gigabit train
2. What does the rail industry need to do to support the achievement of the
Gigabit train
3. What can Government/regulators do to support industry
4. What is missing from the industry that would help facilitate developments
of achieving the Gigabit train
5. What are the next steps that are SMART
6. How and when can all this be achieved? Should we set targets now and
who should take ownership of the responsibility to deliver?
