Re: VietNam Has Live Demo 5G Systems
"The station is fed through a fibre optic cable. The antennae are relatively low in height (demo system)"
No - this is the challenge of 5G. MUCH shorter masts and more of them. Existing mobile towers are likely fed with fibre anyway (i.e. 1Gbps ).
The real challenge is will 5G offer what carriers/customers want or is there a slower 4G+/6G solution that offers a 5G-like experience without the significant increase in mobile real estate. ie. Verizon's LTE Advanced which is deploying some of the 5G features (increased MIMO and QAM) with a small increase in towers
