It's hard to hit moving targets, but subscribers to 4G and LTE networks need to be assured that their data has better protection than just being part of a high volume, fast-moving flow of traffic. This is a key issue with LTE architectures – the connection between the cell site and the core network is not inherently secure.
Operators have previously not had to consider the need for secure backhaul.
2G and 3G services use TDM and ATM backhaul, which proved relatively safe against external...
