8. What makes wireless work?
● Technology:
● Cellular, Wi-Fi, PMR, BLE, TETRA/ESN, OB etc.
● Based on stadium owners requirements
● Topology:
● DAS, Small Cells, Relays, Repeaters
● Structured wiring, fibre, coax, antennas etc.
● Spectrum:
● Based on technology chosen
● Licenced spectrum (Cellular, PMR etc.)
● Licence exempt (Wi-Fi, BLE etc.)

10. Let’s look back 20 years
15 January 2018 Confidential & © Real Wireless Ltd. 2017. All rights reserved.10
Typical early stage In-Building Wireless Solutions (IBW):
● GSM based
● 2 bands - 900 & 1800 MHz
● Single- or Multi-Operator
● Active or Passive DAS
● BTS or Off-Air Repeater fed
● MNO funded
● Coverage was a differentiator
Landlords were not very enthusiastic

11. What changed in the last 20 years
● Download speeds went from 9.6 kbps to 1 Gbps
● The iPhone revolution started in 2007
● Video to be 75% of all mobile traffic by 2022
● Voice accounts for < 5% of total traffic today
● Mobile (arguably) became a “utility”
Outside in will not work well for data

2G
• GSM
• Voice, Text
• In UK since
1992
• 900 and 1800
MHz
3G
• UMTS, WCDMA,
HSPA
• Data: typically 1
Mbps, but
increasing up as
high as 42 Mbps
• In UK since 2003
• 2.1 GHz mainly,
now 900 MHz
for better
coverage
4G
• LTE
• Data: typically
5-15 Mbps, but
potentially as
high as 100
Mbps
• Becoming a
ubiquitous
global standard
• Hundreds of
devices now
support LTE
• 700 MHz, 800
MHz, 1800
MHz, 2.6 GHz,
3.5 GHz

15. Topology, architecture and infrastructure
● What solution
● Small Cells
● Distributed Antenna Systems (DAS)
● Radio Remote Units (BBU/RRU)
● What infrastructure
● Comms Rooms & Antenna Locations
● Structured Cabling / Fibre / Coax
● What architecture
● Centralised versus Edge
● Star versus Ring
Infrastructure inside is essential – how far ?

16. Development of a telecoms strategy
● A “Telecoms Strategy” is key to meet the venues/stadiums requirements
● An independent advisor can represent the venue/stadium throughout the project
● This “honest broker” can ensure that:
● the fans needs are taken into consideration from the outset via the venue owner
● the right solution is chosen (e.g. DAS, Small Cells or BBU/RRU approach)
● the performance requirements are met
● it is realised within the projects economic restrictions (Capex & Opex)
● a suitable and future proof infrastructure is deployed

17. Conclusions
● Each stadium is unique
● There is no single best technical solution
● Who pays?
● Ultimately the venue (and/or MNO)
● Focus on benefits, not ROI
● Ensure that the infrastructure is right
Consider a “Telecoms Strategy”
