Objective

Making a white paper of GTI on the concept/ideas and definition how to make 4G HW can be smoothly evolved into 5G
1) RRU evolution to 5G
2) Architecture evolution of 4G C-RAN to 4&5G C-RAN
3) Maximizing usage of pre-5G HW to evolve to 5G
-Radio hardware: wide bandwidth radio technology, massive MIMO support, high-speed fronthaul interface, modulation 256QAM
-Baseband hardware: 5G ready hardware expansion, high bandwidth processing, high throughput, high-speed fronthaul and backhaul interface, massive machine communication, Minimized latency, build-in resiliency
-Other hardware: high speed optical modules (QSFP+, SFP28, QSFP28)
