This Week In Wireless
- Rowell recorded a video on Wi-Fi 6 on David Bombal’s YouTube channel

- 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.
- SpaceX Launches 60 Starlink Internet Satellites Into Orbit
- “The Starlink satellites will orbit much lower — between 210 and 710 miles above the surface. That reduces the
or latency. SpaceX has said performance should be comparable to ground-based cable and optical lagginess, fibernetworks 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
- Certification on
non-802.11 technologies (BLE, Cellular, Zigbee, wired-side technologies, location services, APIs, Project Management) Firstclass 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.

- How to Design Wi-Fi for Higher Education
- Very Dynamic environment!
- Very High Density of devices
- There are a lot of ad hoc requests throughout the event
- 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
- 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.
- Configuration of the Wi-Fi
- Public Wi-Fi
- Keep it as simple as possible
- If possible, no Captive Portal
- Private Wi-Fi
- Understand if you need to configure QoS
- Create AP groups and RF Profile to be as flexible as possible
- Use all the channels you can (even DFS, 165)
- Place the temporary APs as close to the clients as possible
- Use the people and floor element to content the signal and limit the CCI and optimize your channel re-use
- Do you use DCA or static?
- Study the use of more specific features (Probe Suppression, AirTime fairness…)
- Public Wi-Fi
During the Event
- Adjust the RF settings based on where the people are
- Busy Areas
- Lunch Areas
- Handle Requests
- Setup new SSIDs
- Add coverage in specific areas
- Battle the ROGUES
- Make sure people turn their ROGUE APs off
- Find solutions to answer their needs (using the existing infra or alternative solutions)
- Ekahau with a sidekick
- Wi-Fi scanners (Explorer Pro)
- Screens 🙂
- Your favourite terminal application. My new favourite: iTerm2
- Your favourite network diagnosis tools. My new favourite: Mtr
Ideas to help us supporting such events
- Can some of the configuration and monitoring be automated?
- Create your own monitoring dashboards
- Create your own scripts to automate some tasks
- Create a simple application to process the AP tracking
