Mobile data technologies

It's been a while since I passed by the lounge

Wanted to share these two pages. I was looking for GSM standards and needed a reference to carrier signals.

Mobile data standards

Frequency reference

@SynoMan says he has infinite space on this server. Like exabytes of terabytes and gigabytes with lots of megabits inside them
So I keep posting!

Glad to see you back posting. Here's a cookie for you

there is also WTTx as bridge between 4G and 5G. Perfect solution for rural areas.
WTTx is a 4G & 4.5G-based broadband access solution, which uses wireless to provide fiber-like broadband access for household (xDSL replacement).

Tested 1,5y and really happy in my parents house. The deployment is really quick (external antenna, cat6 cable, WTTx router). Internet speed for this kind of technology is limited to 200Mbps, there is one and only dependency - direct view to BTS from your roof/window/balcony.... (no weather dependency). Stable.

That's interesting. So how far can I be from the BTS? I mean I might use binoculars and can see it, is that ok?
No distance limit as far as I can see?

There's a lot of health concern debates now especially with 5G being deployed. And if you come to think of it, all of this is new (20+ years), we don't really know the long term effects on our health if any. 5G is polarizing people's opinion more than ever.

We have to die from something right :P?

We have to die from something right :p?

So let it be 9G For us...

 

[Rusty]

Considering how fast they are pushing out xG technologies... we will die soon

 

[WST16]

We are all going to die?! All of us?!
What a miserable forum this turned out to be!

There there @WST16, how about a box of 's? Just got a fresh truck of them

That’s more like it. It was getting depressing with this insinuation that we are all going to die.
Thanks.

I’m sure that we were going to die if we made calls on a GSM mobile phone. That’s what they said in the mid-90s.

Might’ve been an indirect relationship to the increase need for electricity and burning fossil fuels?

@WST16 they take a long time to cook in the solar power oven, sorry for the wait. Here you go

Macrosite BTS (scalable sectors, 50 users/sector) up to 5Km
Microsite BTS (just one sector for max. 30 users) up to 2Km, really cheap

WTTx is just enhaced LTE, but for "Fix Air" usage. Then WTTx is LTE TDD. An explanation:

LTE is defined to support both the paired spectrum for Frequency Division Duplex (FDD) and unpaired spectrum for Time Division Duplex (TDD).
TD-LTE does not require a paired spectrum since transmission and reception occurs in the same channel. In FD-LTE, it requires a paired spectrum with different frequencies with a guard band.
TD-LTE is cheaper than FD-LTE since in TD-LTE there is no need for a duplexer to isolate transmission and receptions.
In TD-LTE, it’s possible to change the uplink and downlink capacity ratio dynamically according to the needs. In FD-LTE, capacity is determined by frequency allocation by regulatory authorities, making it difficult to make a dynamic change.
In TD-LTE, a larger guard period is necessary to maintain the uplink and downlink separation that will affect the capacity. In FD-LTE, the same concept is referred to as a guard band for isolation of uplink and downlink, which will not affect capacity.

And what about the fact that more and more (meshed?) wifi's are appearing everywhere?

I mean, look at this jungle of WiFi's. I live in an appartment complex, and the rest of the streets are also appartments...

 

[Rusty]

Same @Shadow. Moving to a house in a short while and will setup a 5G mesh but I’ll definitely be alone. In my current block it’s the same thing. Still the only one running with AC on high ports so no wifi problems

There're textile products that can limit one's exposure to electromagnetic radiation. Something like this by Swiss Shield (the girl is not included).

There are many brands with different prices and varying effectiveness— yes we researched this

The movement to the cave is imminent

Get a futuristic look and Faraday cage in one go by 'wallpapering' your rooms with aluminium foil

Surely you'd have to sleep with the covers over your head?

 

[fredbert]

Not a problem for a narcissist or having poor eyesight

by 'wallpapering' your rooms with aluminium foil

Much cheaper and in case you need to put something in the oven urgently and you’re out of aluminum foil, you can “borrow” from your wallpaper too
