(lower right side) https://books.google.com/books?id=QS0iAAAAIBAJ&lpg=PA50&dq=new%20911%20service&pg=PA49#v=onepage&q&f=false While an operations issue and not a technical one, in Philadelphia a boy died from a beating because police did not get the message. Multiple people called 911, but the operators or the system failed to properly prioritize it and by the time the cops arrived the kid was dead. The parents sued the city and won a settlement, but they graciously said to have the money used to upgrade the city's system to one that actually worked and hopefully save future lives. (As an aside, the offenders being 18-19, were deemed juveniles and got only five years in jail. The victim was one of mistaken identity.) ------------------------------ Message-ID: <20190323020419.GA9063@telecom.csail.mit.edu> Date: Sat, 23 Mar 2019 02:04:19 +0000 From: Bill Horne <bill@horneQRM.net> Subject: AT&T's "5G E" slower than Verizon and T-Mobile's 4G LTE services, report finds By James Sanders AT&T's "5G E" network is just LTE Advanced. An OpenSignal report finds no meaningful advantage to AT&T's network over the networks of Verizon or T-Mobile. Users of AT&T-branded smartphones began receiving software updates in January that replaced the "4G" or "LTE" icon to read "5G E," as part of the carrier's attempt to blur the lines between two fundamentally incompatible mobile network standards. The move prompted T-Mobile to mock AT&T on Twitter, while Sprint sued AT&T for deceptive marketing practices, and placed a full-page ad in the New York Times bemoaning the situation. https://www.techrepublic.com/article/at-ts-5g-e-slower-than-verizon-and-t-mobiles-4g-lte-services-report-finds/ -- Bill Horne (Remove QRM from my email address to write to me directly) ------------------------------ Message-ID: <bcf02ae8-129c-4933-80d5-038c913caafd@googlegroups.com> Date: 22 Mar 2019 14:19:45 -0700 From: HAncock4 <withheld@invalid.telecom-digest.org> Subject: Re: early fiber systems On Wednesday, March 20, 2019 at 8:33:04 PM UTC-4, Eric Tappert wrote: > The first long distance system was installed between New York City and > Washington DC along the NE corridor in 1983, at a much higher rate > than DS-3.
