A total of 26 different manufacturers were detected, which is slightly less than the 33 manufacturers we identified in 2006.
In the Canary Wharf district, equipment from 16 different manufacturers was found, five of which are the most common and used by 15% of the networks.
The equipment of the other 11 manufacturers is used in less than 10% of the networks.
The volume of unidentified equipment (Fake, Unknown, or User Defined) increased from 10% in 2006 to 76%.
Cisco was able to maintain its foothold at Canary Wharf, despite the amount of equipment from this manufacturer having almost halved in number. CyberTAN was squeezed out of second place by Airespace, a manufacturer that was not featured in our previous reports.
In London as a whole, as we noted above, we identified 26 manufacturers. Equipment from the top five manufacturers was used in 15% of all networks, just as in the Canary Wharf district.
The volume of unidentified equipment (Fake, Unknown, or User Defined) grew from 15% in 2006 to 76%.
The main difference between the London as a whole and the Canary Wharf district is the top five manufacturers.
Cisco was squeezed out of first place by CyberTAN, and Aruba and 2Wire have lost ground to Linksys and Airespace. Only Netgear's share has not changed.
The most important and interesting factor when it comes to wireless networks is the correlation between secure and unsecured hotspots. Since we first started wardriving in 2005 in Beijing and Tianjin, each city we investigated set new records in this area.
Beijing’s figures showed less than 60%, which was down to 55% at CeBIT 2006. London in 2006 was recorded at 50%, and Paris seemed to have achieved the unachievable with only 29% of networks not using encryption. Warsaw did fairly well this spring - better than London - with 42%.
We were happy with the results we found during our visit to the British capital this year. First let's take a look at the numbers for Canary Wharf.
