- By 2020, 4 in 5 Mobile internet subscribers will be accessing the internet using mobile broadband.

- More than 9 Billion Mobile subscriptions by 2020

- Social Media and Video adding a lot to data demand

- 35000 Petabytes of data per month for Video content by 2021.

- Neutral Host scenarios getting more and more common.

- Higher frequencies for more capacity, makes it difficult for building penetration.

- With limited bandwidth operators need to have in building and small cells for better QOS.

- Higher modulation requires higher SNR.

Support multi-operators (5) infrastructure sharing

Frequencies: 700M, 800M, 850M, 1800M, 2100M, 2600MHz

Systems: IDEN, GSM, UMTS, LTE + WiFI

Very high capacity demand

Sau Paulo stadium for example: 18 sectors (12 sectors for the bleachers), 32 Master Units + 50 Remote Units

Wi-Fi add more capacity: 100-150 APs to cover the bleachers

For all 12 stadiums, there were 3,724 cellular antennas installed for indoor coverage and 1,014 Wi-Fi antennas

Wi-Fi Doubles the Data Capacity

45

In Wi-Fi enabled stadiums, almost 50% of the traffic is carried by Wi-Fi network

People intends to use WiFi as much as they do with 3G/LTE

Brasilia stadium: Capacity 70,064 72 indoor APs + 141 outdoor AP
