That has a lot of implications. Various large campus-style environments such as ports, airports and maybe business parks, industrial ..read more

Please follow / connect to me on LinkedIn, to receive regular updates (about 1-3 / week) While the broad concept of #privatewireless seems to be getting a lot more awareness in the wider tech industry, some of the implications haven't quite fully landed yet. I've had a couple of meetings recently where there was still a prevailing view that #5G evolution would continue to be "top-down", with major M ..read more

Please follow / connect to me on LinkedIn, to receive regular updates (about 1-3 / week) It's always interesting to attend non-telecom industry events. Too often, we breathe our own smoke. Visiting another sector's conferences gives better perspective. Often, networks are less important than we imagine for "verticals". Yesterday I chaired the Connectivity stream of the World Passenger Festival conference i ..read more

This blog combines two separate, linked LinkedIn articles published in June 2023 on consecutive days. The original posts and comment threads are here and here. Measuring #mobile data traffic is important for operators, vendors, and policymakers. As I've said before, we should use *good* #metrics to measure the #telecoms industry, rather than just *easy* metrics. This post is an example of what I mean. Yesterday, Ericsson released its latest Mobility Report. It's always an interesting trove of statistics on mobile subscribers, networks and usage, with extra topical articles, sometimes written ..read more

Please follow / connect to me on LinkedIn, to receive regular updates (about 1-3 / week)  There have been recent headlines about the possible ending of on-train passenger #WiFi services in the UK. It is deeply controversial. Apparently the Department for Transport (DfT), United Kingdom has insisted rail WiFi must be "justified financially". It's unclear if that means by extra ticket sales, higher cus ..read more
