The appropriately-named Flash Networks in Israel claims that mobile broadband is now capable of consistently outperforming landline broadband services.
With Vodafone claiming speeds of 7.2 megabits per second in London and other major cities, I almost believed the Herzlia-based firm's press claims - until I thought about the packet latency issues.
Unlike landline copper circuits, mobile phone connections are effectively radio connections and, as such, are subject to small delays as the signal moves between devices.
These delays - known as packet latencies to the Dilberts out there - don't normally affect voice calls, but are noticeable when, for example, you're surfing the Internet.
To claim, therefore, that a mobile broadband connection is faster than a landline link, is a bit silly. Or a bit too flash.
