DT1 broadband FAQs

Can I assume gigabit in DT1?

89.2% of postcodes have it, so most likely. The 10.5% on 30-300 Mbps are the exception.

Are there any very slow postcodes here?

No. All postcodes exceed USO standard.

Why is wireless coverage absent?

Terrestrial networks, mostly cable, reach all premises.

How does DT1 compare to the wider Dorset area?

DT1 is the best-served. DT2, DT6, and DT7 show materially lower gigabit and higher below-10 Mbps.
