Network monitor OpenSignal has released its mobile networks update for Belgium and it reveals BASE as made the biggest improvements.

OpenSignal spent 90 days measuring the Belgian market from the start of May. It found that BASE has taken the lead in the key 4G download speed metric, having been level with Orange six months ago. BASE now averages 45 Mbps, up 5Mbps from the last time, while Orange has fallen off to a mere 34 Mbps. Proximus is right in the middle with 39 Mbps.

None of these are bad scores, it should be noted. An OpenSignal test on your correspondent’s phone running the EE network in north Herefordshire yielded 24 Mbps. The overall Belgian speed rankings reflected the 3G scores, as you would expect, while coverage was pretty identical for all three. Here’s some more data.
