How do satellite systems fit into 5G?

As we are bombarded from all over the places with the repeated phrase that “5G will not be only about higher speeds and shortened latency, but it’s the whole ecosystem change”, the question arises, do the satellite systems also fit in this picture? Based on recent research and 3GPP standardization discussion, the answer seems – […]

Mobile network architecture – 4G design issues

This time I’d like to sketch the current LTE mobile network architecture. After the basic introduction of nodes and interfaces in-between them I’ll underline the most important aspects in terms of network design. The design issues are discussed in the context of radio interface and the IP-based interfaces within RAN and CN.   LTE network architecture […]
