Do they make USB range extenders or wireless USB hubs?
« on: October 11, 2018, 10:56:34 am »
As always I'm trying to find ways to make my laptop stay wireless but play with my SDR. Is there a product that could make a usb signal wireless like a wireless USB hub? It would just be a standard protocol maybe or is the USB really fast with a huge amount of bandwidth especially with an SDR and packet drop would ruin it?

The closest I have found was a video by Kevin Loughlin W1aew on youtube(looking for video) where he goes to sdrplay to rpi then uses VNC to control the rpi. Can vnc connect a windows pc to a Linux rpi? It just runs the "standard" interface protocol like sending a mouse and keyboard signal along with the screen correct? It's just a simple interface and why the scammers on the internet use it for Leeval 7 Microsoft techneecal support tech neecians right? Last time I used tightVNC it seemed laggy but maybe that was the internets fault. He uses internet protocol with his router wirelessly connecting the two.

Someone should invent a wireless SDR with 802.11 ip in it. I wonder if electronics that only us geeky people played with were main stream products, like DVD players and phones, could have rather then the other way around: ie a TV tuner was turned into a SDR or a phone ARM processor was turned into a rpi. They do have a cell phone with a 2m and 70cm ham radio in it. Or I would like to see generic android phones turned into application specific devices like a form factor similar to the shell that FLIR has for the phone then make the phone like a star trek tricorder. The phone just serving as screen and CPU. A girl can dream can't she?

Um, something you should have already done, but apparently haven't.

Search for "wireless usb" with your favorite search engine.

I had one once but the problem is the wireless USB end that connects to the laptop has to run off of a power supply and was big and clunky. Unless they make both ends self powered?


I'm going to use Bing and will be the fourth person today to use that site.


EDIT: I tried webcrawler and AltaVista but they didn't work. Yahoo is just full of ads so bad that the search results are not hits but relevant ads disguised as results. Search for a free copy of windows 10 on google and you get a free DVD image first or second result, try that on yahoo and three pages of paying for the software or buying a copy through the mail. The old get something for free and charge for it hoping people don't notice scam. Ironically these companies get away with this but a guy I heard about from a Louis rossman video said a guy got jail time for charging 5 cents for a CD that had free apple soft ware. The 5 cents was to cover the cost of CD so he wasn't even profiting. Wonder how many people apple has sent to jail or worse their deaths from the roof of the foxcom building. They improved working conditions though there are suicide nets now. Good job. Can I have my head phone jack? I hate recharging shit or not having a line out. At apple you don't own the head phones the head phones own you.  :palm:

There are lots of SDR's on the market with ethernet ports, you can just plug a Wifi Bridge in to one, like a TP Link pocket router.

If you don't mind a long cable rather than Wireless I've got a SDR up a pole outside running off a 10m active USB extension, works perfectly fine and runs 24/7

Wish I had known that. Wonder if the SDRPlay will do Ethernet. How hard is it to turn USB to Ethernet? I think I remember having a router that did this? Maybe... it was something USB that you wouldn't expect to work over USB; like a cable modem, but this was when high speed internet was 4gbits. Be cool if you could take a wireless router and plug USB into it.


Are there chips that take a USB and turn it into eithernet or is this a complex process that involves a CPU? What goes inside my router anyways? I want to open it up and discover its just a spliter like old phone jacks and we have been paying 50$ for splitters all these years. I remember when people first started to get internet customers would come into my work and say "No I don't want to spend $60.00 on a router I just need a splitter to hook two computers to my internet (cable modem or DSL box). Oh yeah? here's a 2.00 splitter it will totally work, computer geeks pay $60.00 because they are stupid. Mr customer certainly outsmarted my upsell. I had one lady get mad say she was going somewhere else to buy a splitter for her internet. I wish I was working the day she came back to buy a router, I would have rubbed it in so bad. "Wait you told me you just needed a splitter and I was trying to oversell you. How much was the splitter? Where did you find it because I'm going to buy one and return my over priced 'router'." Its just a fat phone jack that's all.

That's not bad in China for people with no degrees.

What does it take to get into a university in China as compared to other countries generally (if you know) ? Who pays - the gubment or family?
I told my friends I could teach them to be funny, but they all just laughed at me.

their deaths from the roof of the foxcom building. They improved working conditions though there are suicide nets now.

Foxconn is a shithole. Period.

It pays more than most Chinese factories, sometimes double, but it's very depressive. The culture in Foxconn can drive people mad.
It has gang activities, it has underground gambling inside, and you share bedroom with 11 other people while the public toilet for a floor doesn't have even separators.
I shared bedroom with 3 roommates when I did my undergrad, and even with only 4 in a room, there is always one that never showers, one rubs his dick in front of the other 3, plus one listening to music with speakers.

Only the most desperate people work there -- lack of ability to do more intelligent works, and needs lots of money in no time -- those with family members needing money to go to hospital without insurance or savings, those with huge debts and with mafias hunting them, or those just want to work for a month and stay at home for a month.
Foxconn pays ~$300 per month as basic salary, and ~$300 for overtime for average workers, more if you want to work longer shifts. That's not bad in China for people with no degrees.

Put that into perspective, both my parents work for Chinese government, one in tax dept, one in health insurance dept, one as office worker with deputy rank, one as head of district bureau.
They both hold graduate degrees, and they make $1700 combined.
My cousin also works for my local tax bureau at the lowest level (fresh graduate), and she makes $350 per month.

$600 is indeed great in China for people without a degree, but not a lot can stay long in Foxconn. They usually make enough money to start their next career, and leave.
It is that depressive.

Also, many come to Foxconn with suicidal intent in the very beginning. Some want to scam money for their loved ones, some want an exit from debt collectors.
People don't go to Foxconn without a huge need of money in no time.
The only exception being students studying EMS and logistics or pursuing a technical degree having their summer intern for a month, or those wanting to spy on Apple's latest products.


I alwayWhen you say 300 Month do you mean $300USD eq, or do you mean 300 RNB?

Wow I always wanted to ask what it was like. Do they make you live in housing they own and is that the only housing around? Do they have stores where they sell things to you like a factory town then over charge, because its monopoly, allowing the monopoly to get their money back? How/where do you cook your food into little closet sticking the place up? I feel your pain: I got tricked/desperate and moved into Living at a bad place slightly smaller then your dorm, with Chinese peasant of the lost generation.  They older sick hand no concept of clean at all mice and bug are all over the  kitchen, That doesn't work well.

So why would you kill yourself instead of just finding another factory?  Do they do that thing where they hold you in debit by charging rent? How does "you" working, scam family members?

So when you say get paid 300 that equal to 300 USB (I meant to say U$D but the internet is on my mind right now haha) or 300RNB?
I know workers don't build one phone from start to finish but how many could you build in three months for the cost of a new 900$ iPhone here? 300?3000? I hate buying apple after I was subjected to their antisucid mental half cure. 3000 would equal 10 cents labour thats fail. In america if got minwage to make that many iphones you would get paid $4.40 perfone. So paying labor of less then 5 bucks for a $900 phone was too costly? Thats greedy.

Do they make you work 15 hour days and physicall threaten you if you dont? Can you come and go where ever you like?

Are most of the people uneduvated and have criminal back grounds?
What are the hours like it?When  punch a clock can you work more hours if you want? Or do they tell people come in/stay after the clock or do shut off to get caught up? How did you get out?
I had one of those jobs where you punched in and going 5 minutes realy would getyou and improbably them in trouble.

Do they make you live in housing they own and is that the only housing around? They offer dorm for free, but you can rent around.

Do they have stores where they sell things to you like a factory town then over charge, because its monopoly, allowing the monopoly to get their money back? No. People go to Foxconn only to make money. If they can't they don't work there.

How/where do you cook your food into little closet sticking the place up? Cooking is not allowed for fire safety reasons. They offer dining for cheap.

I feel your pain: I got tricked/desperate and moved into Living at a bad place slightly smaller then your dorm, with Chinese peasant of the lost generation. I paid 1200CNY per year for my dorm when I did my BS degree. Can't complain it. I actually rent outside, and I only live less than a few days in my university dorm before final exam.

They older sick hand no concept of clean at all mice and bug are all over the  kitchen, That doesn't work well. Most dorms have either cleaning service or rules to keep clean.

So why would you kill yourself instead of just finding another factory? To scam a big chunk of money. If you mom needs a kidney transplant and you have no saving nor does she has a good health insurance, you may consider the same. China doesn't have Medicare/Centrelink. If you don't save enough in cash or insurance, you're fucked.

Do they do that thing where they hold you in debit by charging rent? How does "you" working, scam family members? Either of us has problem communicating in English.

I know workers don't build one phone from start to finish but how many could you build in three months for the cost of a new 900$ iPhone here? 300?3000? I don't know. I never worked there.

I hate buying apple after I was subjected to their antisucid mental half cure. 3000 would equal 10 cents labour thats fail. In america if got minwage to make that many iphones you would get paid $4.40 perfone. So paying labor of less then 5 bucks for a $900 phone was too costly? Thats greedy. Foxconn gets much more than that. You get paid $600 per month doesn't mean the company spends $600 per month to keep you there. Foxconn pays full health, loss of employment and retirement insurance for their employees, plus Chinese government takes ~30% tax on gross margin. Also you need to keep the machines in good condition. Overall, hiring a $600/mo worker, you pay $1000 on the person plus tax, maintenance, etc. I won't surprise the real cost goes beyond $2000.

Do they make you work 15 hour days and physicall threaten you if you dont? Can you come and go where ever you like?  No, but you don't get to make more money. Chinese law requires double hourly wage for overtime labor, so workers want to work more. They will literally fist fight for working more.

Are most of the people uneduvated and have criminal back grounds? No. All have at least secondary degree, most have a rubbish bachelor's degree. They're not cons, they just don't have good capability.

What are the hours like it?When  punch a clock can you work more hours if you want? Or do they tell people come in/stay after the clock or do shut off to get caught up? How did you get out? You need to ask supervisor to be granted overtime. That's another reason why people don't stay long -- you get to make good money when they have orders. When they don't have orders, you get paid peanuts.

I think your English is better then my typing. Sometimes I can't see what I'm typing and it looks like I have the English skills of a Chinese peasant. The worst part is in America you used to a choice where things were made, I always looked at that when buying. When the news says "but consumers want cheap goods" I say BS there are lots of people who would pay more for quality products, that's just a cover for more profits. In the 90's the economy was great and all our clothes were made in the USA. So they can make a huge profit with American made they are just greedy.

Sounds more like the 1960's when 95% of apparel was domestic. By the 1990's it was down to about 50%. Today it's about 2-3% domestic.

If Ethernet is acceptable, but your SDR doesn't support it, maybe you could use a USB-over-Cat5 extender pair? I don't think they actually use Ethernet (so you couldn't run it through a switch or router), but they use the same cable.

There are also devices (some routers, some standalone devices) that make a USB device accessible over the network. They're usually made for sharing printers and hard drives only, but they sometimes work fine with other kinds of USB devices too.

The discussion of Foxconn working conditions is interesting too, but I have nothing to add to that.

I refuse to use AD's LTspice or any other "free" software whose license agreement prohibits benchmarking it (which implies it's really bad) or publicly disclosing the existence of the agreement. Fortunately, I haven't agreed to that one, and those terms are public already.

USB has strict timing requirements, for example a device can PLL sync to the host's Start-of-Frame (SOF) packets if it doesn't have a sufficiently good clock.  Isochronous modes transfer a certain number of packets for each SOF.  Many messages like SETUP will have very limited response times, and if the device doesn't respond in a timely manner the host will either drop it or it won't ever successfully enumerate in the first place.  This makes extending USB over ethernet an impossibility.  Network protocols operate on much more lax timing.

Not to mention USB is fundamentally a polled architecture, where the host tries to read from an endpoint every, say, 1ms to see if it has anything to send.  This stuff is anathema to networks.

USB can be extended with a USB hub which in the single port version becomes a bridge.  There are also custom USB extenders which use optical fiber or Ethernet cable for longer distances.

Better would be to use Ethernet which in its native form already supports much longer distances.
