This document summarizes Dean Phillips' presentation on delivering eduroam WiFi connectivity beyond the University of Aberdeen campus. Key points include: - The university has partnered with Aberdeen City Council to provide city-wide eduroam WiFi access using the council's public sector network ducts. - Future ambitions include expanding eduroam to additional public locations like the airport and train station to create a virtual city-wide campus. - The partnership aims to commercialize the public sector network infrastructure and further enhance the student and staff experience through ubiquitous connectivity.

17. Selected parameters
ITU-R IMT-2020 Requirements
> The minimum requirements for eMBB peak data rate are
as follows:
– Downlink peak data rate is 20Gbps
– Uplink peak data rate is 10Gbps
> The minimum requirements for eMBB peak spectral
efficiencies are as follows:
– Downlink peak spectral efficiency is 30 bit/s/Hz
– Uplink peak spectral efficiency is 15 bit/s/Hz
> The target values for the user experienced data rate are
as follows in the Dense Urban – eMBB test environment:
– Downlink user experienced data rate is 100Mbps
– Uplink user experienced data rate is 50Mbps
> The minimum requirements for 1-way user plane latency
over the radio interface are:
– 4 ms for eMBB
– 1 ms for URLLC (3GPP target = 0.5ms)
> The minimum requirement for control plane latency is
20ms (Proponents are encouraged to consider lower
control plane latency, e.g. 10ms) 3GPP target = 10ms)
> The minimum requirement for mMTC connection density
is 1,000,000 devices per km2
> The minimum requirement for eMBB and URLLC mobility
interruption time is 0ms

18. Pioneer bands:
> 700 MHz band - to provide a coverage layer
> 2 x 30 MHz + 20 MHz centre gap - SDL - 2019
> 3.4 - 3.8 GHz band – to provide a large amount of contiguous
spectrum for high-data rate and low-latency services and a capacity
solution in congested areas
> 150 MHz in the 3.4 - 3.6 GHz band in 2018
> 116 MHz in 3.6 - 3.8 GHz band in 2019
> 26 GHz band - to provide “fibre-like” data rates and very low
latencies at short distance, as a capacity solution in very congested
hotspots
> 24.25 - 27.5 GHz - date tbd, likely auction post WRC2019
Note: Existing bands could be refarmed to 5G and more bands are likely in the future…
