AT&T echoed comments from Verizon Communications and Google by stating that mobile networks have different needs to fixed infrastructure when it comes to “net neutrality”, the principle by which operators do not differentiate between different types of services delivered over their networks.  It  argues that the finite and shared resources that underpin wireless services, coupled with sharp increases in traffic, means that mobile broadband is  “simply different” to fixed and, as such, should be regulated differently.
