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 be 15GHz).

Here’s the relevant quote from Ericsson’s PR:

“Ericsson has developed advanced antenna technologies with wider bandwidths, higher frequencies and shorter transmission time intervals, as well as radio base stations built with baseband units and radio units developed specifically for the 5G trials and already succeeded in achieving bitrates of over 5 Gbps in live, over-the-air demonstrations of the company’s pre-standard 5G network technology.”

If this sounds familiar, that might be because these are the exact words Ericsson used when it announced 5G trials in the 15GHz band with NTT DoCoMo over a year ago.  Here’s the section from that  2014 release.

“Ericsson has developed advanced antenna technologies with wider bandwidths, higher frequencies and shorter transmission time intervals, as well as radio base stations built with baseband units and radio units developed specifically for the 5G trial”

Although the research may have moved on, Inside5G wonders if the people at Softbank know that NTT DoCoMo got first bite at this press release?
