Deja Vu? Ericsson taking wideband antennas into the field with Softbank

Ericsson has said it is taking some 5G trials into the field with Softbank. Details in its release are sparse, beyond the usual 5G rhetoric (“common understanding of 5G use cases and deployment scenarios” etc). But it looks from this section quoted below that the company will be looking into wide bandwidth antennas and some higher frequencies, perhaps still in the sub-6GHz area as well as one higher band? (For reasons which will quickly become clear, Inside5G thinks this might…
