CTS 172: Conference Wi-Fi

This Week In Wireless



* Rowell recorded a video on Wi-Fi 6 on David Bombal’s YouTube channel* Long version: https://www.youtube.com/watch?v=uZMA4p00c9g* Short version: https://www.youtube.com/watch?v=r62vs2uyQjM* Huawei* Huawei is temporarily pushed out of the Wi-Fi Alliance* Wi-Fi Alliance is fully complying with the recent U.S. Department of Commerce order without revoking Huawei Technologies membership. Wi-Fi Alliance has temporarily restricted Huawei Technologies participation in Wi-Fi Alliance activities covered by the order.* https://www.androidauthority.com/huawei-wi-fi-bluetooth-990610/* SpaceX Launches 60 Starlink Internet Satellites Into Orbit* https://www.nytimes.com/2019/05/23/science/spacex-launch.html* “The Starlink satellites will orbit much lower — between 210 and 710 miles above the surface. That reduces the lagginess, or latency. SpaceX has said performance should be comparable to ground-based cable and optical fiber networks that carry most internet traffic today. Starlink would provide high-speed internet to parts of the world that currently are largely cut off from the modern digital world.”* CWNP new certification: Solution Administration* https://www.cwnp.com/certifications/cwsa* Certification on non-802.11 technologies (BLE, Cellular, Zigbee, wired-side technologies, location services, APIs, Project Management)* First class will be in September 2019* In the future, additional certifications will address key areas in greater depth, such as automation/integration, IoT, private 5G, etc.* Wi-Fi Images* Instagram @cleartosend* https://www.instagram.com/cleartosend/* iBwave webinar* How to Design Wi-Fi for Higher Education* https://www.cleartosend.net/designing-wifi-networks-higher-education/



Conference Wi-Fi



Challenges



* Very Dynamic environment! * Very High Density of devices* There are a lot of ad hoc requests throughout the event* ROGUES* Very intense, long hours, little sleep



Prep Work – A lot of it!



* Understand the type of event* Understand what type of people will be attending* Understand which application will be used over the Wi-Fi. Any critical ones?* Understand the layout of the conference* Where will the stages be* Where will the VIP zone be* Where will the media zone be* Where will the TV broadcaster zone be* Where will the registration zone be* Understand the flow of people* Prepare the LAN* Size it properly so it can handle the number of devices expected (2.5 devices per person)* Make sure the basics are covered* DHCP* DNS* Firewall* Core network* PoE budget* Prepare alternative plans just in case something goes wrong with the basics* What do I do if the internet goes down? Maybe plan for a backup internet link* What do I do if my DHCP server goes down?* What do I do if my DNS server goes down?* What do I do if run out of PoE power?* Make sure that you have enough internet bandwidth* Prepare the Wi-Fi* Understand the limitation of AP placement* Leverage the APs installed under the ceiling* Understand where to place temporary access points if required* Do you have access to cables from the floor* Plan to have APs ready to go and being deployed fast* Size your controller properly* Forget 2.4GHz, plan for 5GHz. Expect to see a lot of 802.11ac devices (and a few 802.11n devices)* Stage as much equipment ahead of time as possible* Organize the APs, name them properly and keep track of them in a document* Tweak the RF on the under ceiling APs as much as you can.
