There's also around 400 MHz of dedicated sharing-only spectrum in mobile bands, available in the UK at a flat price per 10 MHz required. (Replying to GP) At least in the UK, no bribes or envelopes of cash required. Nobody is going to w

The threat posture of both networks is quite different. As a user, as you rightly point out, TLS means it doesn't matter to you much! But if you turn it around and thinks about the problem as a business user, where you have some ancien

Don't force your dreams like this to be grounded! There is complexity in this, but remember here you're talking to people who chose to get deep down into the tech in every component out of a desire to learn, do it themselves, and

Exactly. The whole baseband in your phone is considered "trusted" by the network because you can't easily control it. Don't give the carriers ideas - if they thought they could move to a "ma Bell" style of you

Not OP you replied to, but have done similar before. Answering your questions in order (at least the ones not specific to that scenario) to share some thoughts, which are certainly not answers by any stretch: - setting up a mobile network i

In general, cellular technologies have been designed against assumptions of a clean (or at least exclusively used) RF channel. 4G and 5G are deployed with frequency reuse between base stations, which implement the same standard and can coor

From memory, I believe GSMA (the industry association that helps to keep mobile technology dominated by carriers that hold exclusively licensed spectrum, if you're cynical) require everyone who provides eSim to have been security audit

TVWS channel allocations often don't align neatly with duplex paired 3GPP bands, meaning you might need multiple adjacent TVWS channels. In addition, in many countries the TVWS regulations only cover specifically authorised devices whi

I understand that NR-U is a full implementation of a 5G base station (and client handset/CPE if you can find one that actually implements NR-U!), and therefore you will require patent licenses for the full implemented stack. In an idea

Unfortunately not - eSim is a fairly closed-shop ecosystem. You can't easily type in the provisioning parameters into a QR code generator and get an eSim to use. You need to work with a GSMA-approved eSim issuer who has a special CA-si

In the UK there are 2 ways to get access to long-term spectrum. It's also usable from a bands and handets perspective! 1. Shared access licence. There's 3.3 MHz (duplex paired) of former DECT guardband available for local use at t

I do wonder if the workplace safety/health and safety approach can be used here to good effect - even if your company's activities are nothing to do with safety, your workplace has to, by law, be safe, and company officers are res

Indeed, I was using LTE as an example of the peak standards benefit, but in Europe this simply hasn't been a factor for decades. 2G and 3G were similarly uneventful and straightforward (for the most part).

Not really - many are still running it on legacy appliances like they have done for years. There's also a lot of implications of moving CSFB type functions into the IT environment due to completely different security assumptions in bot

It strikes me that companies need to look back at covid and consider the value IT provided to their business during that period, and the extent to which it has grown their business since the 90s. Then take that and allocate a reasonable chu

There's significant misalignment of incentives at play here (irrespective of company, generally). Many "management types" are measured solely and almost entirely by the bottom line - the share price in a traded company, or pr

One of the common complaints I hear from MBA-type CEOs is they don't understand what to look for in a security person. This means they often end up with a similar MBA-style smooth-talker who says they're good at security, and talk

The US (not sure about Canadian) mobile market is completely different to the European one. It's almost alien in comparison - the carrier tries to control absolutely everything, and generally sees the handset as an extension of their n

VoLTE has been "broken" (from a standards perspective) since before it even launched in most markets - it is just too "finicky" and configuration-specific. LTE/4G demonstrated the success of standards in that it &qu

They are using 4G/LTE cell broadcast, with integration on the back-end to Gov.UK notify. There's nothing truly from scratch here (thankfully), other than integration at non-telecoms layer to get the system working. I believe there

It's very odd. I don't know how Microsoft implements their own server-side spam filtering, but the issue was coming from their filters. No issues with any other host. G Suite accounts received plaintext mail fine. I never found mu

My guess (pure speculation) is that more spam is auto-generated via email libraries and similar, and that is producing plaintext mail to try to simplify what it's getting through the filters. On the other hand, most human-generated mai

To share one trick I found (after you've done all the DKIM/SPF/DMARC/PTR things others point out), if you still have deliverability issues to Microsoft 365 tenants, it is worth sending mail as HTML rather than plain text

Your symptoms sound exactly like the issues I was having - everything was "right" (in theory) - emails were leaving on the right IPv4, that had the correct PTR, etc etc. I just couldn't figure out what was wrong. It was the s

One "weird trick" I discovered with deliverability was that plaintext email from my server was rejected, but HTML email from it was accepted. For anyone with deliverability issues and mail going to spam, it might be worth trying t
