Can Qualcomm broker a peace deal between LTE and Wi-Fi in unlicensed spectrum?

Mage

Wi-Fi stakeholders

Ultimately the Public, consumers. Qualcomm is no-one's friend, they are out to sell chips & licences. They will want this. I'm not convinced Operators do. I know decent ISPs won't touch unlicensed spectrum.

I think this is Qualcomm greed.

Mobile Operators misuse far too much spectrum (Coverage in Ireland FALLING due to lack of regulator conditions) already because Regulators love the licence fees.

Mobile Services and other paid for subscription services should actually be forbidden to use ISM, which should be short range free consumer ad hoc use only/

don’t have the space to accommodate SIMs

No, they do.

Device vendors want to do away with physical SIMs so that they, not operators are in control. The Network operator and Device maker then do deals. Less control to consumer.

Have you LOOKED at a SIM, never mind the pointless new smaller ones (that we don't really need anyway).

BATTERY dwarfs everything else.

It's not about saving space, that's merely spin to justify user loss of control. Unless the device is locked to a network, the operator has no control with physical SIM, user can change it and many governments have demanded users should be able to unlock.

The virtual SIM is all about giving a partnership of a Network Operator and Device maker control and the user less control.

Privacy and Security

We don't need any of these Organisations. So called IoT is been around as long as the Internet, before even websites.

We have plenty of good standards.Cue XKCD (Ah I see it's been mentioned). New ones simply mean gadgets won't play nice with printers, PCs, phones, tablets and Routers.

What we need is enforcement of approved 3rd party CE / FCC testing, in market policing and compliance with basic Privacy and Security standards. But that would remove the major revenue stream Megacorps are drooling about. They'll practically give away this junk if it needs a service contract or subscription, or exploits you for advertisers and revenue.

Gigabit duplex DOCSIS 3.1 passes feasibility study, kind of

Mage
Silver badge

100BaseT vs 1000Base T

1000BASE-T uses all four pairs bi-directionally and the standard includes auto MDI-X; however, implementation is optional. With the way that 1000BASE-T implements signaling, how the cable is wired is immaterial in actual usage.

https://en.wikipedia.org/wiki/Ethernet_over_twisted_pair#Cabling

It does for common Gigabit, but not for 100Mbps.

The reason is that it's easier to do the cancellation for up to 100m than get twice as fast signalling over Cat5e.

Always been in theory possible

In practice this is really really hard the longer the cable, the more variable the cable quality is, connectors and the wider the bandwidth.

Speech on copper pair uses cancellation and there is significant crosstalk. Gigabit ethernet uses this technique and as a result needs much better cable and connections than 100M bps, as well as strict distance limits. it uses all four pairs in parallel, in duplex, versus original cat5 Ethernet which actually only used one separate pair in each direction.

I imagine only part of the 110MHz to 862MHz band will be used and often only on cable that is good quality (no nips, sharp bends, corrosion, poor connections and accurate impedance). At the minute 5MHz to 65 MHz (or sometimes 88 or even 110MHz) is used for upstream which is lower QAM and and TDMA. That's 0.8, 1.6, 3.2, or 6.4MHz channels with virtual TDMA channels in them. Downstream is 2, 4, 6 or 8MHz channels between 110MHz and 560 (old cable), 862MHz or even up to 1200MHz, essentially using DVB-C, but multiplexed data rather than TV.

The problem also is that downstream is really One to Many broadcast (though modems ignore data for other users) and upstream is Many to One, with potentially only 10 simultaneous users if you dedicate a physical channel rather than TDMA. Non-HFC is very much longer cables shared to more users. Hence the typical 8:1 or worse ratio Download/Upload with DOCSIS, though DSL is often worse. Also the QAM is typically lower to reduce modem TX power, this means lower speed. The symmetrical idea would mean very much higher modem power.

A simpler solution on cables not passing too many houses is to use 5 to 500 MHz upstream and 550MHz to 1200MHz downstream. Much more robust than full duplex on the same channels.

Re: Linux vs Win10

NT4.0 32bit Enterprise could use (via PAE) more than 4G

32 bit XP can only use 2.5G application, 4G (minus graphics hole) entire OS. Same with 32bit Vista

I've not tried a recent 32bit Linux on a PAE based Mobo, but certainly on a 64bit mobo, 32bit linux isn't limited to 4G.

Note that address space isn't usually the same as Word size on almost any CPU anyway and unless you NEED a 64bit OS, it might be less compatible with widest range of drivers and do some few things slower than 32bit OS, as well as actually use a bit more ram.

Most 64 bit CPUs do not have 64 bit physical addressing

Most mobos don't even accomodate as much RAM as the CPU can physically control (via PAE or MMU or whatever physical address bus there is.

On a suitable Mobo, with 64bit CPU, you can run a 64 bit VM on a 32bit Host OS too, though that's usually an afterthought, as starting with a 64bit OS might be better if you are wanting VMs too.

Strangely not all 64bit CPUs /Mobos support a 64 bit VM. I've an AMD that won't.

Linux vs Win10

Linux seems to have better support for old hardware (Epson Scanner + PCMCIA 1460 SCSI or PC PCI 2940 SCSI just worked) compared to Win 10

Linux seems to now have good support for new hardware.

Putting Linux Mint + Mate Desktop on 12 year old XP laptop will work, or replacing Win7 or Win 8.x on a newer computer.

1G RAM and 32G CF card or HDD seems to be a reasonable minimum spec for Linux. Less RAM and HDD is usefully feasible for simply LibreOffice, Firefox, Thunderbird, Filezilla and The Gimp. Kindle Reader, Notepad++ and Digiguide work fine on WINE (1G or more RAM a good idea).

Unlike Windows, 8G ram is available even on a 32bit install on a 64 bit CPU.

Strangely Linux version of Skype works better than Windows version.

Linux Calibre works better than Windows version.

So compatibility of computers with Linux, IMO is now better than with Windows 10.

Why would you buy a new PC or Laptop to replace Win7 with Win10?

Surely you'd only buy a new PC or laptop if the old one was broken. Unless you are doing bleeding edge games, or rendering or decent Virtual Reality, you don't need to replace any DECENT PC made in last 10 years for better speed.

I'd like to buy a new laptop without an OS.

Bluetooth direct to the internet: What could possibly go wrong?

Mage
Silver badge

Re: 433/868Mhz RF comms

They are just ASK/OOK slow speed physical links. Lowest level. You put whatever security you want on the TTL serial pins. It's trivial even with a PIC to have a CRC and 256 bit encryption, as the maximum data rate is probably about 1kbps to 10kbps at physical layer, certainly less than 50K. The TTL Serial data needs to be Manchester encoded as the links don't work well with a DC component. Trivial. Some receivers are optimised for Manchester encoding between 30kHz and 45kHz due to the AC band pass filter on the baseband of the receiver. They are really really cheap and easy to get CE approval as SRD. The USA band is at I think 385MHz rather than the European 433 MHz SRD allocation which is slap bang in middle of USA and Europe 70cm Amateur band. The EU 864 MHz SRD band can be less interference, it's wider, so supports up to about 1Mbps simple OOK/ASK or PSK and maybe 16Mbps very short range using QAM.

Re: Bluetooth will always be handy

Bluetooth IS wireless, it's same 2.4GHz band. It can reduce speed of WiFI as the S/N is then worse for wifi.

Simplest is a 3.5mm stereo jack. Though Apple wants to abolish it so that they can charge more for earphones, even though there are stereo bluetooth earphones already. Bluetooth means re-encoding the audio, so in theory it's lower quality than a 3.5mm jack analogue connection.

It's true that the only advantages (especially for intermittent and low data rate gadgets) of Bluetooth over WiFi is the simple pairing (though often too simple with fixed 0000 code and poor security) and lower power (which means very short range, x10 range needs x100 power, that's physics, nothing to do with WiFi or Bluetooth or 3G or 4G etc).

Impossible, because the human race is on average gullible. Loads of people in the family, friends, workmates etc using it.

Companies or media outlets you want to use are promoting it or using it.

Ignoring it is about as viable as using translation, video sharing, maps and search with Google. Is babelfish still running? Dailymotion instead of Youtube, Apple or MS instead of Google maps/Streetview/Earth, Er ... Bing/Yahboo instead of Google?

It's only slightly easier to ignore Twitter.

I predict 5G will mostly be about management, seamless bonding of data channels that use different bands and maybe even 3G and 4G at the same time. Possibly even on Edge. Better integration with WiFi too.

It won't be specifically about new spectrum (any generation can use any spectrum), or new air interfaces or any stuff like that.

Existing recent basestations will work, maybe with a minimum of new controllers.

Nothing to do with IOT or Traffic.

Mobile is CELLULAR. Due to weak licence conditions to drive up licence auctions there are not enough base stations on existing bands.

This ONLY about raising revenue from Mobile Licences.

700MHz is too low a frequency for smaller cells. For more traffic and speed you need smaller cells, more base stations at the under used 1800 and 2100 bands. Even the 900MHz can have far more bases.

They are not even utilising the 800MHz they got from TV properly due to useless greedy regulators.

You talking Linux is your favourite OS? Because while OS X Server edition still exists (Only for Apple stuff), Apple stopped selling real Server Hardware and dropped "Computer" from their name. Also Apple's intention is that OS X should only run on Apple HW. Unlike BSD, Linux, Windows etc.

Apple is purely a Consumer Gadget company that still happens to make some laptops and workstations, a tiny part of their profits.

Maybe Apple stuff "just works" because it's a closed ecosystem? If I buy a TV, DVD player or MP3 player, compared to evil horrible Windows 10, they just work.

Re: Desktop Vs Phone

MS Mistake 1

Putting Win95 style GUI on a PDA/Phone

MS Mistake 2

Inflicting Zune derived Phone GUI (pretty good for a phone vs Win CE!) on Desktop at 8.x

At the VERY LEAST THREE RADICALLY DIFFERENT GUIs:

1) Phone / small tablet

2) Large (10") Tablet, Laptop, Desk top. (if it can't 100% work without touch and 100% only with touch then two separate GUIs)

3) TV type interface, screen at least 1.2m / 4' away and only Sky style remote.

Servers and Embedded need a flexible array of interfaces with GUI option, low bandwidth text remote and ability to script/automate everything, depending on deployment. Embedded might be LCD text panel on a CNC tool, screen + keypad on ATM, cash register keyboard & multiple format screens, or whatever.

Touch screen cash registers and ATM are niche applications.

N0-ONE EVER is going to be able to make a GUI or an app framework suitable for desktop and phone. Phone suitable apps are like widgets on a laptop etc. A full feature productive application taking advantage of a desktop is IMPOSSIBLE to use on a sub 6" phone screen. MS and Ubuntu are moronic even to promote it. For YEARS we have been able to write a Java App for phone and desktop. You can make the SAME code work on both. But it's pointless. Proper desktop Java applications simply don't have enough screen on a phone and phone /PDA/Tablet centric applications on a desktop are either like tray widgets or poor cut down versions of real desktop applications.

Unity is madness. MS's thing formerly Metro Apps is POINTLESS on a desktop. They are both deluded.

I'm no Apple fan, but they did the right thing chopping up OS X to make iOS and sticking Fingerworks derived GUI on phone and mostly leaving desktop OS X GUI as it was (they have degraded OS X desktop usuability, but not for same reasons as bonkers Ubuntu Unity and MS Win 8.x).
