Isn't a major problem with CDMA-based sources that the networks they depend on are getting shut down? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Ethan O'Toole" <telmnstr@757.org> To: "Mike Hammett" <nanog@ics-il.net> Cc: nanog@nanog.org Sent: Thursday, July 11, 2019 9:46:24 AM Subject: Re: Time and Timing Servers
I'm looking for a device that can receive GPS inside a building without the assistance of an external antenna (Frontier says they no longer allow external antenna), will provide traditional NTP services, and will provide a timing signal that my Metaswitch can work with.
GPS inside a building probably isn't going to work unless you have the antenna up against a window. Look at CDMA NTP Servers like the EndRun Sonoma. They use the cellular network which requires accurate timing and has good building penetration. - Ethan O'Toole
