Mobile Telephony for CERN in the Pays de Gex Tony Cass — ACCU — 6th September 2016 cern.ch/dpp: Restricted: CERN Internal
Orange/Swisscom Status All Orange transmitters were enabled by Monday 29th August. Swisscom transmitters in France were shutdown at 2pm on Monday 29th August. During the rest of that week, Orange disconnected Swisscom equipment with some unexpected disruption as the transmitter at point 5 was disconnected on Aug 31st, not Sep 2nd. adjusted transmitter power settings and antenna configurations to meet their needs. “Drive by” measurements of signal strengths in the Pays de Gex are being carried out by Orange this week (Sep 6th-8th). These will provide the reference levels for our “service agreement” with Orange. Mobile Telephony for CERN in the Pays de Gex
Mobile Telephony for CERN in the Pays de Gex Known issues Phones connected to the wrong network stuck on Orange, even when there is Swisscom coverage this depends strongly on how the phone behaves. iPhones switch quickly to Swisscom; more recent Samsung devices stay with Orange. connected to Swisscom even if the signal strength is too low, so calls are missed. Again, this partly depends on the behaviour of the phone, but there is a link to our request to have phones connect quickly back to Swisscom to save costs. We are investigating with Swisscom. Also, Swisscom signals reach France from transmitters in Switzerland. This seems to be a problem around the CCC (from Meyrin/Mategnin) and in Thoiry (from Satigny/Dardagny). People usually working in France should probably manually connect to Orange, and not roam. Lack of Orange coverage Some people in France have no Orange signal, although they do have coverage from another operator, SFR or Bouygues, say. We still need to understand the overall impact of this. How many people are affected? How many are on a piquet rota? Calls are shown as being from …76111, not the number of the caller Unfortunately, the system is “working as designed”, but we are discussing with Swisscom whether there is a way to have the calling number shown.
