However while that will certainly happen at the higher layers of the network – WiFi and LTE are already increasingly intertwined in virtualized architectures and common management systems – the effects will be limited if there is not harmony at the radio level. That will require cooperation between the IEEE and 3GPP standards bodies, but despite plenty of talk there have been few signs of that materializing – until now. The chair of the IEEE 802 standards committee has written to the chair of…
