What is 5G?

It depends.

Briefly, there are actually 3 bands being used with 5G technology.

The 5G low band (600-700MHz) can cover hundreds of square miles with service that ranges from 30 to 250 megabits per second (Mbps) in speeds. That frequency also readily penetrates buildings; think old analog TV signals.

The 5G mid band (2.5/3.5GHz) can cover a several-mile radius that currently ranges from 100 to 900Mbps. That frequency is close to Wi-Fi so think about what Wi-Fi can penetrate, e.g. interior walls and brick but not so much concrete.

Finally the 5G high band (millimeter wave/24-39GHz) works within a one-mile or lower radius to deliver roughly 1-3 gigabits per second (Gbps) speeds. That frequency won't penetrate your hand! This is pretty much only useful in arena type scenarios, e.g. football games.

So the speeds of the low and mid band signals are Ok (250Mbps) to nice (900Mbps) but the real high speed band is very limited in penetration. Think too that to get 900Mbps to even one device will require a gigabit backhaul.

Oh, and not all "5G" phones (don't get me started on AT&T's "5Ge") have radios in all three bands.

Double oh, not all "5G" carriers use all three bands.

Don't rush into 5G mobile phones.

Lenovo Tab M8 FHD

That's one of the worst product names I've come across.

You'll remember that I wasn't thrilled with the Amazon Fire HD 8.
[It] would be tolerable if it was blazingly fast but it's not. 
It only has 1.5 GB of RAM so apps are constantly restarting. The launcher "fix" works by letting the Amazon launcher run then running the alternate launcher so you get a noticeable flash every time you press the Home button. 
I'm just not sure.
So I came across the Lenovo Tab M8 FHD for $120 and went for it. There are several variants. In addition to the FHD there's an HD model with lower resolution.

It's pretty much everything that the Amazon Fire HD 8 isn't.

I don't think it will be getting regular security updates nor Android 10.

Still good enough for a bedside table.

Windows as a Service

Oh, you didn't know that Windows was a service? Just keep reading.

Windows users have been complaining about a problem with the search box for months. There was even an out of band cumulative update ( offered for it in January 2020. I thought that this was the search box in Windows Explorer but it's not.

The search box in question is the one that shows up on the taskbar. That's one of the first things that I disable on a Windows 10 installation.

So I turned it back on and looked to see what build I had.

Since I'm not using it I wasn't familiar with the various build numbers.

The point here is that Microsoft is capable and is, in fact, updating the build of Windows Search over the Internet WITHOUT notification nor interaction. Read this Computerworld article ( about the details. And there's more here ( with examples of dynamic changes.

Folks, that's called "Windows as a Service."

What else is Microsoft updating silently?

That's not what I signed up for.

Office Deployment Tool

Recently I bought a new laptop. It didn't come with Microsoft Office.

I used to have a TechNet subscription that gave me a number of Office licenses but those have all been used up.

I found one of those gray market key vendors and bought a Office 2016 Professional key for less than $30. It came promptly and even included a link to a Microsoft download site.

I downloaded the bits and ran it expecting to get the old fashioned dialog that would let me choose which application and features would be installed.

I usually use that dialog to omit all the Office apps except Word, Excel, and PowerPoint.

But that's not what happened.

The download installed installed all the Office apps without give me any options. As the new laptop only has a 64GB SSD, I wanted to minimize the space used.

I searched for a while and came across several articles on Microsoft's Office Deployment Tool. The instructions were primarily aimed at enterprise installs. After a couple of failed attempts, I came across MS Guides.

The article (.png) is written mainly to describe how to use the Office Deployment Tool to add/change languages within Office. But a few obvious changes tailored it to just what I wanted to do.

The process even automatically downloaded the Office bits.

Are you worried about what Google knows about you? Here's a way to reduce that AND what the web sites you visit know about you.


Their tagline is:.
The world's most private search engine.
While that's not a very high bar, every little bit helps.

Startpage is headquartered in the Netherlands so it operates under the European Union's privacy regulations.

If you've tried alternative search engines, you've probably been disappointed with the results. However Startpage has an arrangement with Google  This is done without saving the users' IP addresses or giving any personal user information to Google's servers.

But the part I really like of Startpage is the anonymous surfing feature. Here's an example.

Here's where the Anonymous View took me.

Notice that the page is framed so that you know you are anonymous. You can break out by clicking on the "door" in the bottom right corner.

I was interested in why there was this big blank space so I loaded the page normally.

The site was trying to get the user to give them credentials.

Good job Startpage!
