RE: [WIRELESS-LAN] Providing wireless on a tour bus

[Hoffman, Douglas]

You may want to look at CradlePoint mobile routers. I have personally used the 
CTR500 with a Verizon USB760 to provide wireless in/around my car for some 
time, which has worked excellent. The CradlePoint devices can even be 
configured to failover from one cellular connection to another (even on a 
different carrier), if coverage issues are a concern for traveling cross 
country. If you're concerned about bandwidth, the MBR1200 can be populated with 
up to five cellular modems and load balance (round-robin, not by bandwidth 
utilization) across them.

I would advise you to proceed with caution if attempting to use 3G/4G 
devices, since switching between 3G and 4G is usually not seamless and may 
happen too frequently when mobile.

  Subject: [WIRELESS-LAN] Providing wireless on a tour bus
  
  Has anyone installed a wireless system on a tour bus that is traveling
  cross country?  Our athletics department would like to outfit their
  bus for long trips to games.
  
  My first thought was to get enough mobile hotspots (perhaps from
  various vendors) to cover the number of users at 5 users each (the
  typical limit).  I could also try a 4G USB modem bridged across a
  small PC to share that link.  For best signal, I imagine that an
  antenna on the roof would be best.
  
  Has anyone done this before?
  
  Thanks,
  
  Nathan

Cisco introduced “private groups” to iPSK in 8.8: 
https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-8/b_Identity_PSK_Feature_Deployment_Guide.html#ariaid-title13

We don’t have any controllers on 8.8 yet, so I haven’t had an opportunity to 
experiment with it. If I had to guess, based on the fact they rolled this 
feature into peer to peer blocking, it only affects unicast traffic. There is 
no indication it would convert broadcast/multicast to unicast and forward it to 
members of the same group. For that reason, I suspect this is not exactly what 
you had in mind… but it may be the closest thing we get for a while.
