Broadcom is now over 3 years late. DT briefed German reporters after their financial call and revealed 35b was now delayed until 2019. This was confirmed to me by Achim Sawall of Golem.de, a reporter I respect..
35b should deliver 200+ meg downloads 500-600 meters, a crucial tool for DT, which is losing share to cable. Cable now covers about 70% of Germany and is expanding. DT now only offers 50-100 megabit DSL while cable is often 400 megabits, going to a gigabit. The government is calling for gigabit fiber, but DT has financial limits that make that tough.
The problem is software; the hardware is shipping and supposedly will work. DT says 35b is not ready to turn on.
