Yesterday we updated our M2M Leaderboard based on our assessment of operator performances since March. The main findings were that there is no change at the top, with Vodafone, Deutsche Telekom and AT&T taking the top 3 spots. Telefonica had a strong few months and closed the gap with the top 3. Other strong performers were China Unicom and NTT DoCoMo, the latter replacing Telenor Connexion in the top 10. Click here for more details.
