I looked before at who had spectrum allocations in the frequencies my boxes supported. I then used Cell Mapper to figure out what technology was deployed on that frequency. IIRC, both US Cellular and Verizon had basic CDMA running in my area on those channels. Sprint was running LTE and 1x Advanced (or something like that), so probably wouldn't have worked out. If Verizon is dropping theirs, then depending on only one company seems a bit unwise.... which means I gotta find some kind of solution by then. *sigh* ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Brielle Bruns" <bruns@2mbit.com> To: nanog@nanog.org Sent: Wednesday, May 1, 2019 3:58:57 PM Subject: Re: NTP question On 5/1/2019 2:50 PM, Andreas Ott wrote:
If you can't get a good spot for an antenna, you could be on the lookout for a CDMA NTP clock. CDMA service is about to be retired in several places, please check in your area before you install a "new" CDMA based time server. C.f.https://www.verizonwireless.com/support/knowledge-base-218813/
I looked into the same thing and decided not to go with CDMA.
There's actually a few other CDMA networks in our area (Boise) besides Verizon, so it wouldn't hurt to look. I seem to remember Sprint is planning to go to 2021? There also appears to be a few smaller independent CDMA networks around as well. -- Brielle Bruns The Summit Open Source Development Group http://www.sosdg.org / http://www.ahbl.org
