BYOD use among Transport for London (TfL) staff jumped fivefold in three years, according to a Freedom of Information request.
The transport network’s mobile device policy saw a rise from 106 devices in use in 2010 to 583 devices this year, according to an FoI report received by network automation provider Infoblox.
The iPhone was the most popular device, with its 320 users outnumbering Samsung’s 87 and Android’s 70.
Apple took second place as well with 178 iPad users, with just eight Surface users and one Asus owner.
Only two Motorola and two Nokia devices were in use, while 22 staff used BlackBerrys – three more people than those who owned an HTC device.
The stats show a steady rise in the number of devices used over the three years, from 106 to 242 over 2010/11, then up to 430 in 2012 before hitting 583 this year.
Chris Marrison, EMEA technical director at Infoblox, said: "Personal mobiles and tablets are becoming ubiquitous in the workplace and IT directors will need to ensure that these devices can be used safely and securely on the network.
"Forward thinking organisations are already putting the necessary measures in place to enable improved productivity through BYODinitiatives, whilst safeguarding the organisation’s network from unauthorised access attempts which put data at risk."
