Geospatial Utility Infrastructure Data Exchange Procedural Guide

This guide is put out by the Michigan Department of Transportation.  Some good useful stuff in here that applies to all fiber contractors.  It’s a good quick read for those of you getting into fiber. You can skip over large sections and still get some information out of it.

Geospatial Utility Infrastructure Data Exchange (GUIDE) creates an organized and sustainable approach to data collection, management, and dissemination of 3D geospatial data on underground utility infrastructure by capturing accurate XYZ information at the time of installation and organizes it in a spatial database format for secure, highly accessible use by downstream stakeholders.

10 Gig SpeedTest server Intel Nuc

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.

Intel Nuc, Sonnet 10 Gig adaptor, Mikrotik HexS

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.

The Software
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.
