Summary Bullets:

  • Diameter signaling is very complex and can be costly for mobile network operators (MNOs) to deliver
  • Wholesale carriers are moving in to help solve these complexity issues on behalf of MNO clients, and in the near future more widely available 4G roaming will help business users be more productive while on the road

Whilst Diameter signaling and IPX seem purely technical terms that have little to do with enterprise IT and communications, the fact is, the implications of these technologies on the way we can be productive while on the move are considerable. Imagine leaving your home 4G network, getting on a plane to travel to another country, and within minutes of landing, zap! you are once again able to enjoy high-speed mobile access and enterprise-quality video and voice. However, users are going to have to be aware of how their cross-border ubiquitous 4G LTE mobile experience is going to cause a huge spike in the monthly bill. We are all familiar with the high data roaming costs that can come with mobile broadband roaming, and therefore the enterprise customer needs to be continually pushing mobile vendors for fairer terms and prices, and already begin conversations on cost effective widespread 4G LTE roaming. Vodafone, for example, has recently suggested that 4G doubles data usage and that it expects 4G to increase mobile data revenues, including roaming, even in the light of incoming EU roaming legislation.
