WN Podcast 045 – WiFi 6e and Future of WiFi with Gabe Desjardins from Broadcom

Welcome to the latest WiFi Ninjas Podcast!

Today we have a pleasure discussing WiFi 6e and future of WiFi with Gabe Desjardins, Director of Product Marketing, Wireless Connectivity Division at Broadcom.

Here is what we have discussed:

  • 6GHz Spectrum & Channels 
    • US = 1200MHz of additional spectrum
      • 59 x 20MHz channels
      • 29 x 40MHz channels
      • 14 x 80MHz channels
      • 7 x 160MHz channels
    • EU = 500Mhz of additional spectrum
      • 24 x 20MHz channels
      • 12 x 40MHz channels
      • 6 x 80MHz channels
      • 3 x 160MHz channels
    • Issues with the SNR and 160?
    • Why are the EU getting less than half the US? 
    • Broadcom have been advocating 160MHz channels. Is this really a viable option? 
    • More channels = more time to scan the channels = could lead to problems for devices to roam, how will this work? Will we scan 100 channels? 
    • Channel numbering scheme? Starting at 1 again in 6GHz (8-bit field 59 x channels barely fits the 8-bit field)
  • What else operate in the 6GHz frequency band? 
    • Any DFS? 
    • TV & Radio?
    • Emergency Services / Public safety? (UNII6 & UNII8) 
  • Indoor and outdoor power constraints? 
    • Low power indoor (27dBm in 160MHz channels, 24dBm in 80Mhz channel) permitted across whole 6GHz band. 
    • Constant EIRP of 30dBm – so even if we double the channel width we keep the same SNR.
    • 5dBm per MHz?
      • No longer lose SNR when we bond channels together
      • Power is independent of the bandwidth (PSD) – ensures the same net EIRP
    • Fixed indoor AP
    • Outdoor mobile AP (Phones & Cars etc) 
    • Very low power (14dBm EIRP) (AR & VR) (In car AP, game controllers)  
  • 6GHz Chipsets & Radios 
    • APs – Multi-bands
      • Tri radio APs? 2.4 + 5 + 6?
      • Quad radio APs? 
    • Will we have antennas that sit natively at the bottom end of 6GHz and can also access the upper channels in 5?
    • When are we likely to see APs & clients with 6GHz chipsets in them?
    • Broadcom launches world’s first WiFi 6E 6GHz chips (Jan 2020)
      • Intended for enterprise APs and residential networks
      • 4×4 dual band 160MHz support
      • 2×2 tri-band
      • 2×2 dual-band with ARM CPU
    • 15 billion WiFi devices that are currently on the market that are not 6GHz capable 
    • Timeline for 6GHz client penetration prediction? 
  • Access/ Edge Switches
    • Currently 1Gbps & 30Watt PoE on average
    • With all this additional spectrum and radio chains their will be new PoE & bandwidth requirements for access switches. What do you think these are realistically likely to be? 
  • WiFi 7
    • 320MHz wide channels? (would be only 3 x non overlapping)
    • What speed would that potentially give us?
    • Even more consideration for PoE budget & bandwidth for access switches.
    • Do you think it’s a good idea to add 802.11ax into 6GHz or have IEEE missed an opportunity to redefine the 802.11 protocol within a brand new spectrum that doesn’t have any backward compatibility to deal with?

Thanks a and tons of love!

WN Blog 030 – USB Network Adapter on VMware ESXi (tested on NUC 10)

Welcome to our latest blog!

If you’re like me and want to have most compact, cold, silent and energy efficient ESXi server at home, you probably looked at Intel NUC more than once 😉

I’m now upgrading (or rather downgrading?) my lovely 2U ESXi that built myself 2 years ago. It is still powerful, but I have no space for it. I will tell you why.

My server room is located under the stairs. It was filled with equipment – Cisco FTD 5506x firewall, Cisco 3560cx switch, Cisco WLC3504, Cisco 9120, 9130, 3x 3702 APs, 2U ESXi server and UPS battery ensuring my NFS storage is not corrupted in the event of a power cut.

All that boxes generated so much heat, that I have decided to make space for clothes airer – my washing was dry just 2-3 hours after putting it inside the server room 🙂 This space could also be used as sauna. 

I then decided to simplify my home network and lab. Moved NAS to the cloud, virtualised firewall (chosen Untangle – amazingly sleek), mounted APs properly outside of the server room and switched to Mist.

Now I’m down to just an ESXi server, 1 small, passive, lovely Juniper EX2300-C-12P switch (that can be managed from Mist cloud!) and 2x Mist APs – AP41 and AP43. No more controllers, batteries, firewalls.

Do you see what my problem is?

Washing don’t dry out quickly anymore, as it’s cold in the server room!

To fix this, I will put a dehumidifier in that room. But I need more space to do it. This is why I wanted to switch to micro server (NUC) – so I can replace the rack with massive ESXi server with dehumidifier.

I ordered 10th Gen Intel NUC with 64GB of RAM and 2TB SSD – it’s more than enough to run my production and lab networks. But since I no longer have a physical firewall, I encountered a challenge – NUC has only one wired NIC card. I now needed two – one leg connected to BT fibre converter (WAN PPPoE) and one leg connected to the switch (LAN). 

After putting ESXi 7.0 on my NUC (it was quite challenging – NUC Intel wired NIC is not supported by ESXi and it required adding Intel NIC drivers to the ESXi image – thank you Bernhard @WiFi_Burns for your help!), I realised that my USB NICs are not recognised when connected.

Additional drivers are required to make it work.

Since we WiFi nerds don’t use VMware excessively, I personally found instructions available from VMware quite confusing and difficult to follow, so I’ve decided to put all steps needed to make external USB network adapters work on Intel NUC running ESXi.

Steps required to use USB Network Adapter on VMware ESXi (tested on NUC 10)

1. Download .zip file from here, making sure you get the correct version for your ESXi (currently 6.5, 6.7 or 7.0 are supported)

2. Make sure Safari (assuming you’re using Safari) doesn’t automatically unzip the downloaded file (Safari > Preferences > General > untick ‘Open “safe” files after downloading’)

That’s it!

Your external network adapters should now be natively supported in ESXi 6.5, 6.7 or 7.0 run on 10th Generation Intel NUC.

I have tried two different adapters, Belkin F2CU040btBLK USB-C and some very old USB-A 3.0 Adata one – both worked perfectly. I left Belkin plugged in as it’s much newer and 2 weeks after switching to NUC I can confirm that I’ve not had a single network performance issue. My USB-C wired NIC is happily used as a WAN interface by Untangle Firewall VM. Happy days!

Lastly, if you need Intel NUC 10th Gen ESXi image without having PhD in VMware PowerCLI and Google, give us a shout and we will share the image, hopefully saving you some time!

Here is what we have discussed:

  • Quick Mist recap – wireless roots
  • Mist & Juniper – filling gaps
  • Mist focus on intelligence (dash, API, machine learning, AI elements, BLE RTLS)
  • Juniper focus on top quality hardware and traditional software
  • Mistifying Juniper – basic switches integration done – why is it so cool?
  • Management of wireless and wired – dash, API, CLI?
  • Troubleshooting and assurance – both wired and wireless in the same place?
  • Pre-reqs to run Juniper / Mist wireless and wired network – any on premise equipment?
  • Management and users data – any concerns about data security with cloud managed systems?
  • Licensing of the new switches – can be combined with simple wireless licensing?
  • Software updates – mandatory and pushed from the cloud?
  • Scalability, templates
  • What’s next?
