GPRS signalling is there any plans on 4g for primary and secondary signalling company’s have there own units in production .will BT WEBWAY be making the move to the 4g networks any time soon 

 

In dual path signalling you can't use the same path for primary and secondary.

Is there a reason for your preference on "4G", with many terms like this it's more about marketing than performance.

There are also differences between counties and the technologies they wish to implement going forward, manufacturers may not wish to make a product several times or different variants if they have a working one with better coverage at the moment.

I see my question was are there any company’s out there that have taken advantage 

of 4g for secondary signalling or even for that matter primary signalling I am aware of PSTN Ethernet etc many thanks for your reply
