Previously I suggested that some 3G or 4G network phone
s data rate (2Mb to 100Mb/sec) could be split into smaller parts and using that same data rate that is now used for one one phone could be split between many users, if data rate is only 20 kilobits/sec this "virtual 2G" network can be installed for example 1000 users instead of only one user using 2Mb data rate. Because teleoperator costs drop now only 1/1000 of previous, and simultaneysly advertisers reach 1000 times more customers (1000 customers can be now reached at the same cost than one customer using 2Mbs/sec data rate, advertiser gets 1000 times more money per customer), total cost free internet for end user can now be true. If 4G/LTE network is used data rates are 20 - 100Mb/sec and splitting that in 20kilobits/second sections brings 100 - 20 000 "data users" in the place of only one customer. However it seems to me that splitting data between customers is not possible in nowadays technology. But there is solution for this: multiuser "phone cell", or multiuser content system. The radio "cell" that one customer uses in 3G or 4G cell phone network is now shared between 100 - 20 000 customers in multiuser content system. Now every message received in this radio "cell" targeted for only one phone is received to thousands of telephone / tablet PC owners. In order to keep messages private data encryption is needed: For example every receiving message has "adress code" similar to individual phone number, altough thousands of phones inside radio frequency cell receive that same message, phone hardware checks the address code in the beginning of the message, and if the address code is not the same as in the telephone, telephone does not react to that message and does not process or open the message. Information can also be encrypted, text (SMS messages and email), and voice can use "scrambler" that military radio phones use to hide its information. So altough thousands of phones receive the same message or information, only if address code is right the phone opens the information, and if encryption is used not even opening the message bring information usable to someone who is not in the same address code. The encryption key must be of course individual to every user. If encryption on the hardware cannot be used or radio communication already uses it in the 4G network, then using double cryptography that uses one code to open the message, but the opened information is encrypted using another coding method, that another code is decrypted in the software in each individual phone. I don t know how video or visual information can be encrypted. There are things like Mikogo desktop that is shared desktop / operating system. In Wikipedia is "comparison of remote desktop software". But this multiuser system is not exatly like shared remote desktop, altough it can be used like it. It can be even better than conventional internet because now one receiving message can be received between thousands of customers if needed instead of one , in the cost of one message, messages like commercial advertisements, or shared messages etc. Negative aspect is slow data rate for one customer, but using sophisticated data compression methods like Finite State Encoding (FSE), or QDigest or other it is possible to overcome this and different audio- video etc. compressions etc. Instead of 3G or 4G LTE, Wifi phones can be used. Wifi phones can be even cheaper to built than LTE phones and data rates are at 4G 100 Mb/sec to 350Mb /sec. That means 5000- 20 000 "virtual 2G" data rate channels, or 5000- 20 000 customers in inside one Wifi cell. Cheapest chinese Wifi phones start at 5 dollars for large factory order, and cheapest GSM phones about 4 dollars, altough both these cheap Wifi and GSM phones are quite primitive. Using Internet of Things protocols (some of them have megabit sec data rates, at least in"burst mode") can be used to bring costs down for both receiving device and teleoperator. On the uplink if messages that are send "crash" because there are thousands of customers in same radio cell, simply "send again" procedure and message on the phone screen resolves this problem. If user wants to share his information, song he is using or video he is downloading, customer can simply left it be not encrypted and without address code, now everybody in the same radio cell can watch the same video or hear the same song. In free internet for development countries only public domain material or other license / royalty payment free material is used, so sharing information (like song or video) is cost free in free internet for developing countries. Public domain means different things in different countries. In USA early Alfred Hithcock are publibc domain but not outside USA. In England old Michael Powell films are public domain but not outside England. In Japan old Akira Kurosawa films are public domain but not outside Japan. If now could be agreeded that if some information is in public domain in its home country (or in the USA, USA is the most used source of public domain material) that same material can be public domain if not all over the world, at least in poor development countries. Altough material is license payment free, the free internet is still funded using commercials, there will be commercial breaks like between Youtube videos, but not opportunity to skip adverts, and in audio stream adverts too. Using graphical user interface in free internet net is full of pop up window comercials. The more money from advertisers free net collects the better, enven licence payment material can then be used on free intrenet of developing countries. If Wifi and IoT is used devices can be very cheap, or even usual phone components. Maximising roll printed electronics like displays, keyboards and batteries and making rest of integrated circuits so cheap as possible in some chinese OEM factory. Printed electronics solar panel on the phone itself can be used as battery charger, or left battery out and use solar panel as only means of electric power, when sun does not shine phone does not work. Or other similar methods like using body heat as energy source etc. Some IoT low power device can work on these methods. These super cheap phones could be advertisement paid, because production costs are 1-3 dollars per phone and then distributed free, without cost to end user in free net. Even "expensive" "smart phones" and tablet PC:s that cost 10 -15 dollars to make in mass production factory price, can be adevertisement paid with commercial sponsors, phone is painted full of advertisement logos, in the hardware level there is adware etc, user must hear/ see commercials from the manufacturer all the years he uses the phone etc. If there is no way to encrypt information individually in one phone radio frequency cell, or use address code that prevent to open messages if address code is not right, then only way to use this multiuser system is that privacy must left out, every message is heard to everybody inside radio frequency cell and that is the price of cost free internet. Like using skywave radio comunication, at low 20 watts every message can be heard all over the world to everybody, that is real "multiuser system" and worldwide without teleoperator costs, because athmospheric propagation transports the message. There are several athmospheric propagation methods different wavelengths from below 1Mhz to several gigahertz, and some are being examined as means of long range Wifi (hundreads of kilometers Wifi range radio communication). These things (multiuser internet for development countries, slow data rate, many customers using same radio frequency cell simultaneysly, either for receiving data or sending) is possible today. Costs will be 1/1000 - 1/ 20 000 compared to nowadays teleoperator costs for one customer. State owned telephone firms are possible the most suitable users. Over third world almost in every country there is teleoperator that is state owned, or partially state owned, by some rich industrial country, some middle eastern super rich country, or China, or development country itself. Teleoperator business is together with weapons trade and oil business one of the most state owned businesses in the world. And this shared multiuser system will perhaps bring huge profits to teleoperators and expand their customer base exponentually to billions and billions more customers. And it will be cost free for end user. Propably private firms like Millicom that operate only in development countries can use this method too. In development countries, even in poorest ones, have today 4G networks, either Wifi or LTE, and state owned teleoperators are using them. Cheap Wifi device is easy to build, even cheaper using roll printed electronics on those parts that are possible to manufacture using it. The multiuser "virtual 2G" concept inside one 3G or 4G radio cell is capable to bring down costs to minimum and expand advertisement money to maximum. For free internet for developing countries. If 20 kilobits/sec is too slow data rate then higher rate is possible. Obviously all 1000- 10 000 users inside one cell are not simultaneysly using net so data rate in most cases can be higher. This "radio cell" is not like traditional cell phone radio cell that telephone networks uses, normally one radio cell holds thousand individual phones.this "virtual 2G" is just one telephone connection in this normal radio cell of thousands of individual phones that have 100 - 350 Mbtis/ sec data rate for one user in 4G network, But in multiuser content system this one connection of 100 Mbits/sec data rate is shared by thousands users. If 4G wifi connection has 350 Mbits/sec data rate, it is shared between 20 000 users. It is like all 20 000 have the same telephone number, because they all are using same telephone connection that is normally used by only one people (altough they dont have the same telephone number, but principle is that one teleophone connection is used by thousands of people). It is like 20 000 people using the one and only telephone at the same time, (although there are 20 000 phones, using only one telephone connection). They can
t all have same telephone number because when people move and use mobile phone they change radio cell and link tower when they move. Despite the fact that people have different telephone number if there are 20 000 people in some geographical area that fits inside one "radio frequency cell" that is normally used for only one telephone Wifi user, all received messages (downlink) will now be received together with 20 000 different cellphones, and all sended radio frequency messages (uplink) of 20 000 phones will go to one telephone connection "slot" of the link tower. The principle is same as net browser that uses only one net connection but the browser has browser subdomains, or many sub- browsers inside one main browser and now many different users can use only one net connection through these sub- browsers inside one main browser- principle (in this case "main browser" is shared between thousands of phones, there are distributed browser, or distributed operating system concepts etc., many different ones, but the phones used in this shared network can still be Symbian or Android etc. if wanted, and shared network is just simple communication protocol inside Symbian or Android phone, or go step further to complicated distributed operating system concepts, byt because simplicity is needed in free net these high-tech concepts are propably not needeed like distributed operating systems. Dooble browser itself is in its original distributed form and now a "desktop" or sort of simple operating system). Multiuser browsers with one net connection are iSpaces, iCube (previously called iRock or Rocknelt browser) etc. This is the same situation like multiuser browser inside one phone using one net connection, but not used for internet browsing only but all audio and video communication also, and those 20 000 cellphones have the same multiuser browser for one telephone connection to link tower that has 20 000 subdomains. In normal multiuser situation all messages received will automatically go to 20 000 cellphones. For privacy all messages and received information downlink have individual "address code" in the beginning of every received or send message, (text, audio or video) and now phone sees should it react to message, and open the message (right address code) or not to open the message (address code different than in on the phone), and perhaps individual encryption or double encryption for privacy. For tablet PC or laptop this same method can be used, and in the net browser browser "subdomains" that share one browser to several users, like iSpaces Cloud browser/computer. Maximum data rate is 17 kilobits/sec in this 20 000 users inside one 350Mbits /sec phone connection model. For uplink and send messages to prevent data crashes maybe "waiting on the line" model where one has to wait in the line perhaps several seconds or minutes to have free data slot to messages uplink, after pressing "send" button it takes time until phone announces "message send". Realtime data transfer like telephone conversation is difficult using this method uplink, but perhaps possible using slow dta rate and frequent "data crashes"on the line if many people are using realtime data transmission at the same time. Normally in cell phone radio frequency is shared into cells that use "time division multiplexing" and other tricks, one cell has perhaps thousands users and data rates of one user is from 2Mb (3G) to 350 Mb (4G Wifi). But now this one user slot must be divided between thousands of users, and then thousands of these slots (that normally combine only one user with hundreads of megabits data rate) combine one normal "radio frequency cell". Multiuser content model where information downlink must go to everybody in the same one user radio cell area is only possible solution. If information is individually encrypted or have some sort of identity code, altough thousands of phones receive message only one opens it. when user shifts position and enter another cell phone tower link he is in the area of another radio frequency cell and shifts now to use it and there is another 20 000 people in the same user slot that he is using. This is like normal cell phone operation but insead of one user for one telephone connection there is now 20 000 users for one Wifi telephone connection in shared multiuser model, using same frequency, same time slots etc, same time division multiplexing, same everything, sharing one telephone connection. For voice communication perhaps sharing one speech voice channel between dozens of users brings data rate savings. The cacophony of dozens of voices speaking same time would be enormous, but using "voice scrambler" code that military radio phones are using, individually coded voices can perhaps be separated from cacophony, and using "polyglot synthesis" or other to make information audible, at least speech voices of telephone conversations and internet radio speech voices. And using CELT type speech synthesis. Now several speech voice channels can now be transmissed using only one channel for voice. All this shared multiuser content system thing, one radio frequency connection normally aimed for one user shared between many people, "virtual 2G" system, can be used in 3G, 4G, 4G LTE or in Wifi networks. For voice communication, because "wait on the line" model is used, perhaps radio telephone (trunked phone network) type communication (push to talk over cellular) that is already possible in some phones, after one say something on the phone he/she presses "send" button on the screen, then voice is send using data compression, "beep" sound gives signal when data packed voice is send, if signal is not heard that is because data crashes on the upling have prevented message, pressing "send again" button and perhaps now message goes through. This kind of push to talk over cellular limits voice channels to one (instead of two) and makes voice communication possible even in "wait on the line"procedure. Radio protocols like TETRA, its british equivalent, Tetrapol or Project 25 operate at low frequency range (about 100 Mhz lowest) and does not neek link towers, because contact is direct between phones. Motorola IDEN and WiDEN and european OMA PoC are similar but inside mobile phones, and does not neet link tower either. Low frequency gives more range to phones and slower data rates, but one link tower can now cover much large geographical area. Thats why CDMA phones are recommended for development countries because their lower frequency than GSM gives them greater range and therefore less infrastructure (cell phone link towers) are needed. CDMA phones are more expensive by avarage than GSM phones, but only because they are manufactered in smaller quantities, when mass production reaches same level as GSM phones there is no difference in prices of GSM or CDMA. CDMA requires however less infrastructure costs because of greater range. If GSM frequencies go down to same leveI as CDMA, GSM can cover the same area as CDMA also. If frequencies go down to 100 Mhz which is close to TETRA etc. networks, range is even more greater and perhaps athmospheric propagation methods becomes one way of communication to over long distances, athmospheric propagation have several different areas and methods between about 90 Mhz - 430 Mhz, and even more below 90 Mhz. Chinese TD-SCDMA is a rival of western 4G netwoks, and it is specially designed not to include western licenses, so it is cheaper then western versions. Japanase iBurst is not anymore developed cell phone standard, it is capable of low data rates and low bandwidths, and it is in use globally. It has good spectral efficiency as 3G standard, in the Wikipedia "spectral efficiency" page, so it is consuming less bandwidth, but 4G standards consume even less. "LTE-Direct" is a phone standard like Motora iDEN where phones contact each other without the need of link tower, range in LTE -Direct is 500 metres. So it is possible to keep infrastructure costs down if phones don`t need link towers so often than they nowadays do and link towers can be sparsely separated. There is a text "An intelligent extracting web content agent on the internet" 2005 MIng-Huey. Using Ogg Opus as speech / music codec and Daala etc. as video codec no license payments are needed for video / audio codecs. However, if there is commercial codec that require license payment as hardware devioce, if that is more efficient than license free codec, license payment price has no signifigance because more efficient data compression helps to bring data rate price down and so it is significantly more important than one 0,5 -1 dollar etc. license price of commercial hardware codec. More efficient compression saves perhaps many dollars per month from data rate costs, and better service and content can now be offered at cost free internet."Shruti Drishti" is a special web browser for visually impaired text-to-braille coneversion tool, developed for development countries own use. Previously chinese factories manufactured super cheap "wristwatch phones" that were just basic GSM phones without operating system (some had Symbian), phones where wristwatch type, minimal size display, WAP text browser was optional for extra price, and price for phones was 1,35 - 2,5 dollars. But mobile ineternet made these basic phones outdated, and last models were manufactured 2013 - 2014 about. SoC was Coolsand or cheapest Spreadtrum etc. no mali graphics so WAP text browser was only option. MP3 player was however included. Minimum order of quantity was 10 000 - 50 000 phones for super cheap basic phones. Text browser without graphics is still option in cost free internet, together with efficient text compression, without video/graphics processor phones can be made cheaper. However using printed electronics even 7 inch tablet PCs can be made cheaply, display is most expensive component of tablet PC, if that and keyboard (no touchscreen is needed) and battery can be made with roll printing mass production, super cheap tablet PC, that can be used like Google virtual cardboard phone glasses as 3D glasses also, and together with printed electronics made solar panel (solar panel can be on the backside of tablet PC etc.) or using body heat or other heat source as battery charger etc, and cheap lamp (roll printed manufactured) that will bring light at the evening and uses tablet PCs battery. This phone/ tablet PC / 3D or 2D glasses/ lamp combination can be made very cheaply and paid by commercial sponsors and advertisers together with adware, and internet connection (low data bitrate) will be advertisement paid too by commercial sponsors. In third world and poor countries this is possible.Or combination of primitive 2D or 3D video glasses together with "Android TV stick" style cheap Wifi computer stick, that is cheap to manufacture, but this TV stick works as phone/ tablet PC, not just a TV Wifi middleware. This "Wifi computer stick" / cheap video glasses/ headphones / lamp -combination is all that is needed for audio and video communication and light at night. Extra internet time is possible to earn using "advertisement watching work", watching adverts for hours and earn some money or credit or internet time.
