Four years ago, security researchers showed how a flying drone could hack an entire room full of Philips Hue smart light bulbs from outside a building, by setting off a virus-like chain reaction that jumped from bulb to bulb. Today, we’re learning that vulnerability never got fully fixed
Apparently, some of the new GE refrigerators and their filters use an RFID chip to validate if the water filter is genuine or not. This reminds me of the great printer ink wars.
There are even articles on how to hack your 3rd party filter.
Recently a client testing their 5G solution came to me asking for a solution to testing speed from their CBRS/5G/802.11ax clients. One of the requirements was it had to support greater than 1 gig speedtests as close to the devices as possible. This particular client has a small cell device which has room for a small form factor PC. The challenge was finding a small PC that could handle a 10 gig port.
In steps my buddy John from Columbus. John is up on hardware more than I am. After some talks, we settled on the following two pieces of hardware
Once we assembled this we need a router for the Internet and DHCP. We chose a RouterBoard hexS
As a not both of these will run off DC power. The Nuc comes with a 19Volt power supply so if you are running Pure DC you may want to drop from, say a 24volt battery bank to 19 volt with a Meanwell converter.
Proxmox was installed on the Nuc. Nothing crazy about this. Just make sure the thunderbolt adaptor is plugged in during install. For our purposes, we are just using the 10 gig adaptor. Proxmox recognizes the adaptor without a hiccup.
In some earlier blog posts I wrote about the self-hosted speedtests.

I installed the self-hosted speedtest under a Centos Minimal Install. Everything was put on a 172.16.x.x network. This was done in order to prevent any conflicts with various types of Internet the Mikrotik may be plugged into. By default, port 1 is set up to be a DHCP client. In our setup, the Internet is the bottleneck, but we are not testing the Internet. We are testing clients on the 5g/CBRS/802.11ax network. Our 10 gig port on the nuc will be plugged into a 10 gig switch at the small cell, and not into our routerboard. The routerboard is just there to hand out DHCP and allow Internet access, if available.
You may have heard of Ethereum as a cryptocurrency. What you may not know is that Ethereum is so much more. Ethereum is a distributed virtual computing network that stores and enforces smart contracts.

In this article, I am going to talk about how WISPs can monetize their networks in the ever-growing hype of 5G. Whether you think 5G is hype, or overblown from a technical aspect, you need to embrace the 5G wave of hype and use it to your advantage.
Many WISPs should be familiar with 5G in terms of how small cells work from a technical, physical, and a philosophical viewpoint. This knowledge is important, as outlined in Small Cells and hybrid networks for WISPs: Part 1, as well as making your network attractive for Network as a Service (NaaS).
Wireless Service providers, especially ones with active community ties, have a unique advantage over the larger providers such as Verizon and AT&T when it comes to small cells. Many of the local WISPs have the contacts to be able to put up small cell infrastructure in their coverage areas. The provider does not have to own any licensed cellular spectrum to do this. Many WISPs can make a business model with unlicensed (2.4 and 5GHZ) and CBRS band. The big benefit of this is if these providers build this infrastructure in mind of selling space to the larger carriers, then it can be a huge benefit. The local ISP is now selling its infrastructure. Many ISPs would rather have one client paying $1000 a month and 10 clients paying $100 a month. With this, you can do both.
How do you do this? In an upcoming podcast, I am going to talk with Tolly Marcus from Airpacket about how WISPs can “up their game” to design and engineer their networks to be in-line with what the larger carriers’ design. This mindset will focus on the thinking processes ISPs need to start implementing into their own networks.
One of the things the local provider can start looking at is small cell poles. Companies like Wytec International are implementing the next-generation of smart poles. These poles tie cellular, CBRS, wifi, iOT, and other technologies in an unobtrusive design. The photo below is from this month’s edition of AGL Magazine.
By looking at this pole we can see the many compartments inside. Cities like this design as it covers ugly wires and just kind of blends in. So, what does this have to do with the WISP? If a WISP were to design and engineer these to take into account the designs the carriers mentioned earlier require then the network can be sold as a service to them. Many factors and things need to be met, but it is doable. Again, the WISP does not have to operate in the Cellular bands in order to put up the pole infrastructure.
WISP puts up these throughout the town or city they can leave options for a carrier or multiple carriers to add their equipment into existing infrastructure. The local ISP is selling capacity on a purpose-built network they have control over instead of the large carrier rolling over them. The addition of small cells also opens up additional opportunities for the local ISP which otherwise might go to a 5G carrier.Some of the opportunities to the local ISP can be •Cellular Small Cells
•Digital Signage and displays
•Informational Kiosks These services are just a few of the ones an ISP with local connections can provide many services needed while selling to carriers who are already deploying small cells. In closing, if you are an ISP, especially a WISP use the 5G hype to further your business instead of trying to fight it. Adapt what you need to your business model to help provide the next generation of services. Don’t get hung up on semantics.
Spectrum use Article
The wireless industry has always had to deal with regular (and alarming) pronouncements that we’re somehow running out of radio spectrum. We’re not. But the misconception regardless gives many IT and network managers pause.
It does not mention WiSPs, but is a perspective nonetheless.
How many of you are focusing on Internet of Everything (IoT)? I have posted some links to how healthcare and others are using IoT to further their business. As a service provider, you should be coming up with an IoT strategy.
Microsoft and IPV6
I have written about IPV6 lately and Microsoft has published a post where they are moving their internal network to an IPV6 only network.
Carriers and telcos are also interested in adopting Kubernetes — AT&T is using Kubernetes as the basis of the Airship project it will use to run 5G and public safety network services — but they’ve already deployed significant amounts of IPv6, especially for mobile networks. Around 90 percent of T-Mobile USA and Verizon Wireless traffic already goes over IPv6; for Comcast and AT&T it’s about 70 percent.
