5G mmW - possible scenario

Recap: Aims of study
Identify top 5 priority bands for early investigation
- Potentially ease the task of investigating “above 6 GHz”
- Aim is not to identify all possible bands
- Not everything can be a priority
- Other bands remain possibilities
- Detailed co-existence studies will still be needed

Primary
- Bandwidth of 1 GHz or more, per operator
- Ease of sharing
Secondary
- Harmonisation
- Economies of scale
- Handset integration
Technology enablers
- Up to 100 GHz: RF and antennas - yes
Path loss @ 200m - yes

Recap: Findings in brief
“Once you eliminate the impossible, whatever remains, no
matter how improbable, must be the band”
(with apologies to Sir Arthur Conan Doyle)
Five potential bands identified
> 1 GHz bandwidth
- Eliminate passive bands, etc.
- E.g. top two bands are
66-71 GHz
45.5 – 48.9 GHz (3 sub-bands)
Avoid PMSE, 6mm Ham band
- Reflected signals are often wanted;
building penetration is low
