Virtual wifi network? piggyback wifi connection? extend range how ?

Virtual wifi networks were suggested quite a few years ago. But a version of which is now in windows7.
Microsoft can do it. I use XP(sp1) and have a wifi adaptor on USB(realtek8191). I use dialup ISP acount when I have only encrypted hotspots. But with Microsoft autoupdate, I can get virtual hotspot free.

What it does, is simple. Your wifi adaptor can change to use some data channels of an encrypted adaptor. and reach a gateway router to internet unsecured. This is the virtual wifi network This technology can extend short range wifi hotspots to cover very large area as long as you have encrypted hotspots to piggyback on it.

This concept started when we proposed fee based wifi piggyback technology. But wifi free hotspot became a reality at stores and public places. So virtual wifi network is also free. Virtual free wifi network can use any data channel on a wifi adaptor(data rates) different(slow 1-2 mbps) from encrypted data rates(54 mbps).

This means Microsoft is already using the new technology to give me the virtual wifi connection, when I am using dialup modem superceded by virtual wifi connection for speed. WiFi 1-2 mbps(60 kBps) is 10x speed of POTS dialup modem 5.7kBps. USB edgeQam(1 ghz) telephone lines are much faster than free WiFi(2.4 ghz).

Footnote:
Microsoft did autoupdated bios administrator on my computers to check out some technology requirement since year 2001. Now, we are working on several new technology for windows. I use XP sp1 to have codes easily changed for the better, instead of sp3 which has more layers of temporary security improvements. I work on new technology but never paid by Micorsoft. Virtual wifi network reduces total number of airwaves to avoid collision and interference.

Does this mean that XP users may get autoupdated wirtual WiFi network to speed up their internet experience; its inevitable. Because its that simple to apply.

Otherwise, third party might cash in.

Unsecured Wifi transmission is going thru the trust factor protection by identity(cookies). There will be mac address encryption and video encryption combination.

MAC address is hardware password. Then location ip address puts hackers out of range.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

Microsoft can make virtual wifi network free hotspot for anyone at their home.

This will have impact on the economy, when more money is changing hands on the net. However, it will make US Post office more important in the economy to run an efficient delivery system. The economy depends on productivity and cost effectiveness. Big business trying to gorge the public will suffer from lack of business. Post office has to employ more young people part time create jobs to average down their pension system. Presently, they have too much overtime workload.

Part timers are usually recruited from postman's family.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

However, win7 virtual network is really a software wifi adaptor to become a router to internet thru cableTV? Or a software wifi adaptor for access point. Or a computer to computer ad-hoc network.

This is quite different from using wifi network and piggyback on encrypted network using available data channels.

One is virtual wifi network much like virtual private network. The other is virtual hardware made of a software driver act as an adaptor to us wifi data transmission.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

Extended range of wifi network is always popular and most people use antenna extension to try for more range.  Some UHF type of reflective antenna can cost quite a few bucks unlike the cheap TV antenna market.

There are problems of wifi reception that is not a matter of range and signal strength. When too many users get together, the lengthy codes of many webpages can not be delivered by sequential packets without checksum remembrance. Yesterday was such a day. Only short webpages are working. Long webpages suffered lossy packets.

most people have seen the charts of distance and data rates. 1-2 mbps has the longest range of distance and signal strength. 54 mbps has the shortest range of transmission. Microsoft has no code logic to slow down data rate to compensate for distance to the router yet. But any one smart will figure that out in time. Quality of link will improve too.

As for long webpages, repeating packet until checksum of a webpage is satisfied will assure the completion of downloading a webpage no matter how long the codes are. This does not change the terrible webpages of too many advertizements of links from DNS servers.

So, the present state of art is not yet fulfilled by short webpage directive. Reduced pixel webpage programming will definitely help. Ondemand servers will stop the mess DNS servers created in the advertizing field in webpages.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

Since 2003 Sandisk announced cf wifi cards, virtual wifi network is installed in flash cards.

WiFi function can be programmed in firmware. And drivers are software only. the hardware used is in the soumd card chipset.

So, windows7 has Wifi virtual network in it. Just software WiFi. Easy to upgrade to the latest speeds.

The trick is to do traffic control in the browser. Not to have too many radio signals to jam other signals. Control webpage downloads by download manager resume if packets got lossy. Reduce total number of pixels per webpage.

This technology is coming.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

Today to extend range of free hotspot, antenna design is very important. WiFi ofter boast of range  extender antenna design. But often antenna does not do the only job. Range is extended by adding low frequency to the network carrier. More frequency discriminator to lower noise ratio. Its no longer like home router that can be feet away, not hundreds of feet away.

Multi element antenna has multi 1/4 wave length of antenna elements. Fresnel antenna design is well proven in cellphone applications.

Then, WiFi is going the way of MIMO. Data channels are going to add hundreds of channels for massive parallel data channel processing. This could be virtual network in SD card as long as you do not run out of memory to cache and swap data.

Data Processing is after all mostly transfer, not calculate. ARM cpu is thus different from x86 architecture and branch prediction of 32 bit data is different too. Not for instruction set, but from phrases of language to be transfer from one memory address to another..

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

Virtual wifi network is already installed in most older windows operating systems.

Except you have to activate it by some one with a network to connect to.

So, cable people will be able to sell subscription to your virtual network connect to wifi routers on the street near your home.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

Recently, Microsoft wifi traffic control is put in place in your browser, with wifi network(icon is screen broadcasting) instant on during booting of the operating system. The glitches of the DNS server not available is gone. Firefox is again cooperating with Microsoft to do wifi traffic control. I am using firefox7 autoupdated to Firefox8.

The wifi traffic control on wifi network around the world will reach all the homes either paid subscription per computer, or free in some countries(paid by real estate taxes collected).

Some R&D is still going on to use higher data rate of OFDM or /g technology. But it looks futile due to resend ratio being too high to waste time. Another discriminator IF frequency stage may have to be added to improve data integrity during broadcast.

So it will stop to have good data transmission again; one step forward one step back until the traffic system can allow more users per router; to improve by slower data rate discriminator soon.

DSSS uses data channels as carrier frequency then data rate as IF discriminator upto 11 mbps. OFDM data rates are 54, 36, 24, 18, 12, 6 and 1-2 mbps as IF discriminator frequencies. Some discriminator frequency need better signal to noise filtering to avoid too high a resend ratio to good RX packet received. Or OFDM needs slower data rates like 1-2 mbps(50-100 kBps) and 6 mbps(500 kBps).

Next step is to add double data rate synchronization on leading edge and trailing edge on discriminator wave form to increase throughput and get better data integrity at the same time using 2x oversampling technology. Hardware or firmware design will be studied for over 1000 kBps transmission speeds.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

When the wifi data rate is increased to 36 mbps at 58% signal strength, the RX retry is 8x of each good rx packet received.

This shows that the throughput of wifi at 36 mbps is still 65 kBps. Most of the speed is wasted on retry of resending same packet eight times over.

It shows that 5.5 mbps data rate is still the fastest speed so far on DSSS signal. OFDM so far had no improved resend ratio because people did not try the slower data rates. I could explain OFDM is used in AM radio stereo and the high frequency response is 1,000 hz. FM or TV stereo response for high frequency is 15,000 to 20,000 hz using 75 microsecond time delay multiplexer. This tell us a whole lot about OFDM characteristic of data integrity of data channels A and B transferring high frequency faithfully.  Data rate can be higher frequency discriminator(TV 4.5 mhz, FM 10.7 mhz) and must be filtered off noises that effects A/B stereo channels to get higher frequency of stereo data.

In wired pots telephone line, the longer the wire the worse the frequency response. In OFDM long range transmission too, the longer the range, the worse the data integrity due to ghost signals. If OFDM is used at home and within 6 feet distance 54 mbps probably has good data integrity(not much ghost signals due to reflecting surfaces in the path of directional antenna).

I think before too long we will develop a feeling for wifi signal integrity and ghost signal reduction technology using oversampling noise reduction of -96db.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

The development of computers in general was from punch cards to magnetic memory for digital computers. It lasted many years. Today, there are many types of memory even flash cards. from flash cards we can built hardware using analog digital mixed signals. So, cheap computers will be made of DSP and huge memory. Many hardware functions will be ambiguous and just by changing the software in memory. virtual wifi network in future tablets will be just a software in flash card.

Indian government has to develop a computer using speech for commands, and only cpu and memory for main components and microphone and speakers(smartphone on internet that can repeat answers). Video screen will be the more fancy design.

It shows that underdeveloped countries only tried to follow and have not tried to be creative in technology where electronics parts can be minimized or made cheaper.

Hopefully, creativity is to be emphasized in India, not subsidy and follow the leaders in legacy technology.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

If you don't use sp3, then your browser is still iE6. Sp3 is required to do iE8 and autoupdate it.

iE8 can do facebook with adobe flash player(webGL) activeX. Instead of (webGL) html5 for other browsers. To avoid directX and do webGL for apps and games in facebook.

Virtual wifi network(hardware build in memory) is dead, taken over by cable set-top boxes marketing.

Its the bigdata webpages which reduced the time on the internet.

Wifi job assignment on each customer is so short a time that busy never happens.

Re: Virtual wifi network? piggyback wifi connection? extend range how ?

Wifi drivers are not good for multiple wifi device installation, often crashes the operating system.

Avoid installing more than one wifi device in your computer.

If more than one wifi shared software, it is difficult to uninstall just one drivers.

Some wifi drivers have the same name can not be installed at the same time same computer.
