2. What we are covering today The evolution of ieee802.11 What does 802.11ac wave two deliver What options are available and should be considered.

3. Wireless LANS In the late 1990’s ieee 802.11 and 802.11b were introduced. Deployed for connectivity in huddle rooms, boardrooms and conference rooms and scanning. Lacked speed, concurrency and was subject to interference at 2.4GHz. Mbps 1000 800 600 400 200 0211 802.11 1997 802.11b 1999

4. Wireless LANS Followed by ieee 802.11 a at 5.8GHz and ieee 802.11g at 2.4GHz. Using 5.8GHz maximum raw data rate of 54 Mbit/s, which yields realistic net achievable throughput in the mid-20 Mbit/s. Using 2.4gHz maximum raw data rate of 54 Mbit/s with a theoretically 31.4 Mbit/s is the maximum but rarely achieved. Small packet size results in 3 Mbps. Mbps 1000 800 600 400 200 021154 802.11 1997 802.11b 1999 802.11g/a 2003

5. Wireless LANS Next came ieee802.11n with some innovative features: MIMO (multiple in multiple out) 40 MHz channels (up from 20MHZ for previous) Deployed as 2.4MHz or 5.8MHz less interference. Mbps 2000 1800 1600 1400 1200 1000 800 600 400 200 021154 802.1 1 1997 802.1 1b 1999 802.1 1g/a 2003 802.1 1n 2009

8. ieee802.11ac and Wave II Wider RF bandwidth (up to 160 MHz) More MIMO spatial streams (up to eight) Downlink multi-user MIMO (up to four clients) High-density modulation x 4 throughput. (256-QAM vs 64-QAM ) QOS defined in the standard Beamforming defined in the standard Fairness in the Air Quality of Experience

9. Scenario Typical client form factor PHY link rate Aggregate capacity (speed) One-antenna AP, one-antenna Station, 80 MHz Handheld433 Mbit/s Two-antenna AP, two-antenna Station, 80 MHz Tablet, laptop867 Mbit/s One-antenna AP, one-antenna Station, 160 MHz Handheld867 Mbit/s Three-antenna AP, three-antenna Station, 80 MHz Laptop, PC1.27 Gbit/s Two-antenna AP, two-antenna Station, 160 MHz Tablet, laptop1.69 Gbit/s Four-antenna AP, four one- antenna Stations, 160 MHz (MU-MIMO) Handheld867 Mbit/s to each STA3.39 Gbit/s Eight-antenna AP, 160 MHz (MU- MIMO) one four-antenna Station one two-antenna Station two one-antenna Station Digital TV, Set-top Box, Tablet, Laptop, PC, Handheld 3.39 Gbit/s to four-antenna STA 1.69 Gbit/s to two-antenna STA 867 Mbit/s to each one-antenna STA 6.77 Gbit/s Eight-antenna AP, four 2-antenna Stations, 160 MHz (MU-MIMO) Digital TV, tablet, laptop, PC1.69 Gbit/s to each STA6.77 Gbit/s What that all means

10. Quality of Experience Networks represent the circulatory system of the organisation; insufficient flow means that productivity is being lost. A poor quality of experience costs money Considerations: System Architecture: wired and wireless Management systems Analytics and forensics = Compliance Financial structure Cap Ex or Opex

11. System Architecture Power Over Ethernet Ensure the Aps work on standard POE AF Don’t use external power supply per AP Energy efficient Automatic reduction of power consumption Single/Dual port or high speed port The AP will be capable of more than 1Gbe Plan to change switches What is the Packet output of the AP to the LAN? Site Planning Higher speed = lower distance e.g. 256 QAM user density Efficacy of device population Ensure the end stations support MIMO ++

12. Management Systems Management systems should include elements from: Planning include maps for location based services Configuration through roles and rules Easy deployment ease of on-boarding users e.g. Active Directory Optimisation through roles and rules Monitoring with alarms and alerts to mobile administrators Ease of use one SSID IPS/IDS rogue mitigation Compliancy reporting Interface to network analytics.

13. Analytics and forensics High density high performance WiFi networks provide complex issues around: User Device Application Location and time of day Quality of Experience

14. Analytics and forensics High density high performance WiFi networks provide complex issues around: User Device Application Location and time of day Quality of Experience Analytics will define all the network matrix needed to see Who On What device Did what For how long/much data Network, server and application latency Enables planning Reporting and compliance

16. Wi-Fi has now turned into a marketing tool

17. Wifi Analytics: collect activity-based data (marketing, technical, etc.), and learn valuable visibility from a variety of metrics, such as the number of unique visitors, their profiles, or the average duration of a session. This granular data can provide you with the means to improve your customer- focused communications by analysing how your customers use the available wireless services. Wifi Marketing all communications can be personalized, thus ensuring that individualized messages get delivered in real time to your online users. Product offerings and special offers can be showcased through banners, pictures and videos that are injected directly into the user navigation session. Payment Wifi. Enable users to immediately purchase good and services whilst on line. Big Data: Create data base of users and behaviour. With wireless-based marketing, the promotion of services and new offerings has become child’s play

18. Financial structure Cap Ex or Opex The high total cost of ownership is driving more organisations to Wireless As A Service

19. Avoid: High Capital cost for an enterprise solution. Specialist staff to manage and fault find Being locked in to a technology Easy Scalability Walled Garden deployment architectures. Cloud Hybrid Cloud On premises.

20. Demand WiFi connectivity, in excess of 90 % of IOT only support connectivity via Wifi
