      How to improve low cost stable Philipines internet connection

      preptorrent · Wednesday, 17 August, 2022 - 17:01 edit · 16 minutes

    Deploy "debian edu" servers (with built-in Squid servers) connected to 802.11g wifi hubs so that students can get basic 128kbps wifi (which will somewhat travel through building walls) per person. A bluetooth (basically a PAN, personal area network) handshake option could be allowed too for those with wifi problems. A Laser inernet (shown as the red beam on the map) links wifi hubs, although a directional wifi instead of the laser part could be used of laser was too expensive. Each user (student) has an (OIDC) open i-d (connect) registration for federated SSO (Single Sign On). So not only educational material but linux security updates can download via that bluetooth or 128kbps wifi from a squid-server as a deb file or tar-gz file with shell script if need be (for installing later when the internet is disconnected or for taking to another PC so that actually even members of the public can get those linux distro security and packages updates if copied to a CDRW or external usb HDD). Even the older bluetooth can allow for 300kbs and so a 128kbps connection should not be a problem. Each building could choose to use light-bulb internet if they wish so as to avoid reducing the bandwidth of available wifi. They would pay for that part themselves though (if they even needed it). Students (child students but also including a few adult medical students) register for internet using OpenID-Connect (OIDC) via SimpleSAMLphp installed on a linux server on the wifi network connected to thet internet laser system (so they receive a federated login SSO, single sign-on and it allows them to access data cached via a squid server).

    Wifi and Laser Internet Map in Philipines

    Purple Wifi circles (also indicating bluetooth) are about 5KM diameter and that would do and be low cost because electricity consumption is low (and can use battery backup), although it is possible the range would exceed those 5KM circles (at each internet "Laser conversion to 802.11g Wifi hub"). Each Wifi hub (as a purple circle on the map) provides a 5KM diameter circle of 802.11g to about 400 students (including some medical staff at the medical buildings in those purple circles also using SSO OIDC via the SimpleSAMLphp), and there are 10 hubs in purple circles so that is 4000 people with 128kbps internet simultaneously, although more could be added if "shifts" are rotated such as 12hour night shift and day shift to double the number to 8000, or there could be 8 hour shifts (if some students do night-classes instead) to thereby triple the number in 24 hours to 12000 people with 128kbps internet, getting 8 hours per day. That is 12000 PC linux computers that therefore get security updates from a Squid-server and those PC machines might be used for offline activity elsewhere such as a family member using LibreOffice to calculate their home dietary plans. That would really mean though that "8 hour" slots are used instead of simultaneously all ten hubs of 1200 PC linux machines (i.e. 12000) using the internet simultaneously from a (approximately maximum) 56Mbps Wifi hub. So each 8 hours (3 slots in a 24 hour day), 400 PC Linux machines would connect to a 56Mbps inernet Wifi hub (in a purple circle). About 360 Megabytes data per Linux PC (of the 400 group subset) would be able to be downloaded/uploaded (shared between download and upload) in that maximum scenario of 10 (purple circle hubs) of 1200 Linux computers (totalling 12000 Linux PC machies) sharing time slots in a 24hour day. There are ways to avoid squandering it all on linux secrity updates if multiple Linux PC computers are willing to share data over their own wifi (faster up to 56Mbps for the 802.11g even if they have no faster a wifi card which they might do), either by KDE connect or mesh networks and even sometimes using software like "DD" and Clonezilla and partimage and fsarchiver and partclone and LVM, all combined, saving data across a network.

    If two such Linux PC computers are near to each other, they can also share what software updates they have received so far between each other using KDE connect or similar software and GSConnect, speeding up the process if one of the PC machines already has the updates especially with Squid-server installed (because wifi is up to 54Mbps peer-to-peer like that), or bluetooth notifications via "nuntius" software. The Linux PC desktop would be likely to be XFCE with a "Whisker menu".

    All 802.11g wifi hubs (connected each to one of multiple debian-edu server which can be a low power SBC) would be sent with an option to connect your own paid-for internet sim-card ISP plan in case the signal drops out (so you have at least 128kbps internet which is a gibayte every 24hours but it woudl not be promised to function per student 24 hours a day but might only run at their own classroom times and homework slots, and so some students rotate their "turn" otherwise a 54Mbps connection only allows, per hub "purple circle", 400 students using it even though there is more ways to share bandwidth than that most limiting scenario).

    This is low cost and allows private ISP companies to still operate. The "entirely free" part (for students) is the "not-internet" (basically a Wifi LAN) 128kbps. A 480p ogg vorbis theora video an be sent via that.

    The investment (which is not to be expensive) is down to using Lasers for internet as "line of sight" along water ways, and sometimes roads. The internet laser won't use up Wifi bandwidth. water ways will always have a line of sight. there may be some relay posts for bening river waters. However, even in a bad scenario, a small vessel (like a boat) could have a laser and wifi device onboard to traverse thet water-ways and improve signals on a rare occassion, like a drone on water or instead a bouy with a drone or (wifi signal) winch-tied baloon that is docked to it.

    Send fast (but low cost) internet via laser line-of sight to multiple "Laser conversion to 802.11g Wifi hubs" (allowing 128Kbps per person) as backup to stop internet connections dropping out entirely.

    Send the Laser for the internet over water mainly but a key point of land would be the linking of Manila Bay (East to West) water to the Manila sea water (i.e. over land East to West from Muntinlupa City Police Station to Our Lady Of Peace Hospital).

    The internet Laser would start at Marikina Bridge, A. Bonifacio Ave, Marikina, Philippines (a Laser conversion to 802.11g Wifi hub).

    So the internet laser would beam along the Marikina River to Marikina River's, Barkadahan Bridge, Taytay, Rizal, Philippines (a Laser conversion to 802.11g Wifi hub). The internet laser is then sent, along the Marikina River. So the internet laser would be beamed from Barkadahan Bridge (a Laser conversion to 802.11g Wifi hub) which is on the Marikina River but the river there meets the Manila Bay water.

    So the internet laser would beam from Barkadahan Bridge (a Laser conversion to 802.11g Wifi hub), over the Laguna de Bay water to Muntinlupa City Hall (Town Hall), Manila S Rd, Putatan, Muntinlupa, Philippines (a Laser conversion to 802.11g Wifi hub).

    From Muntinlupa City Hall Town Hall (a Laser conversion to 802.11g Wifi hub), the laser would Link (over land) along the road (Parañaque Road), thereby linking (over land, East to West) internet from the bay water to the Manila seawater. From Muntinlupa City Hall Town Hall (a Laser conversion to 802.11g Wifi hub), the laser would Link (over land) to Muntinlupa City Police Station (a Laser conversion to 802.11g Wifi hub). So then from that Muntinlupa City Police Station (a Laser conversion to 802.11g Wifi hub), the internet laser would link to Olivarez General Hospital, San Antonio, Parañaque, Metro Manila, Philippines (a Laser conversion to 802.11g Wifi hub). So the internet laser would then link from Olivarez General Hospital (Laser conversion to 802.11g Wifi hub) over land to Our Lady Of Peace Hospital, E3, Parañaque, 1700 Metro Manila, Philippines (a Laser conversion to 802.11g Wifi hub). The internet laser then links from Lady Of Peace Hospital (Laser conversion to 802.11g Wifi hub) across the Manila Bay sea water to Orion Municipal Hall, San Vicente Bridge, Orion, Bataan, Philippines (a Laser conversion to 802.11g Wifi hub).

    So the laser internet across the land from Orion Municipal Hall, San Vicente Bridge, Orion, Bataan, Philippines (a Laser conversion to 802.11g Wifi hub) to Centro Medico De Santisimo Rosario Inc. (Laser conversion to 802.11g Wifi hub).

    So the internet laser then links from Orion Municipal Hall (Laser conversion to 802.11g Wifi hub), across the land (having already corssed thet Manila Bay Sea water) to Sasmuan Municipal Hall, Pampanga, Philippines (a Laser conversion to 802.11g Wifi hub).

    The internet laser then links from Sasmuan Municipal Hall (Laser conversion to 802.11g Wifi hub), along the (Jose Abad Santos Avenue) road, the laser links to Department of Foreign Affairs, San Fernando, Pampanga (Laser conversion to 802.11g Wifi hub). The internet laser then links from Department of Foreign Affairs (Laser conversion to 802.11g Wifi hub), so the laser could be sent along waterways (canals and rivers) if need be.

    It (the laser map and short wifi range) avoids using as much wifi bandwidth as possible (because it is laser internet) and the wifi available is only 802.11g (with bluetooth options too) and at that only 128kbps so there is a low bandwidth standard for educational linux video and XML data deployment which is capable of 480p video per student. Families and companies can purchase a small "extra addon" to combine this infrastructure (128kbps 802.11g) wifi with their existing sim-card or microwave bandwidth ISP internet to avoid dropped signal.

    This means that newer internet technology (via capitalism) is not intruded upon via this bandwidth (because it is limitedby being 128kbps and only 802.11g so as to get through walls) and also a person with an old deskop PC installing linux (presumably debian-edu aka skole-linux with a squid-server) can find it more likely that their old wifi dongle or PC-card (and 802.11g compatible) device will work with it (and they can use thet FCC ID to identify it for drivers or NDISWrapper). That can be the case even if they have a desktop PC which is 32bit i586 (circa 1Ghz CPU) or amd64 CPU (or intel equivalent or raspberry-pi3b) as long as they have say 256MB RAM or preferably 512MB RAM in the computer. Basically a "How TO" guide on upgrading your PC RAM would be provided so as to try to get as many old computers running 512MB RAM (or even over 1GB RAM) as possible. The Kwort Linux distro would also be acceptable.

    The debian-edu would be a low cost deployment. When it comes to paid-for deployments, people would probably be looking at Red Hat Linux (and Microsoft linux subsystem) both of which are good but they would have sufficient knowledge as an individual by then that such a subset of people would use a paid-for deployment solution usually for business or organisations paying Red Hat or Microsoft for a custom solution (as, like Apple they too have linux or BSD unix-style in their own operating systems). Students would be encouraged to have a usb-hub with mutiple usb-mass-storage device pendrives (about 7 where two are for index and 5 are for raw data, which gives the equivalent storage of about 4 such SDA drives) to make a BTRFS array as backup of data even though their main (SDA1) HDD is the normal linux distro on an HDD. It helps Squid-servers and snap-shots. So (purchased by students for their own PC or raspberry-pi such as a pi3b) the 7 usb (pendrive) "SDA" drives for BTRFS would be 32GB each (or a cheap 28GB NAND storage version), storing squid-server data (so basically 112Gb is four data SDA drives of circa 28GB each because 5 drives will give data equivalent to only 4 drives, and we remeber the other 2 drives in thet 7 are essentially for a form of indexing where if one fails, it can be replaced with an identical blank to repopulate the drives). If one of thet 5 data (not index) drives fails, it too can be replaced with n identical drive bought by the student to repopulate with data from thet other 4 data drives. A student could, if they wanted, have that data backed up to their own privately owned 120GB HDD such as with the cloning or backup tools one might find on a linux CDROM/DVD or knoppix and UBCD (both, on different disks or installed on a HDD also). The main OS is not booted on thet those 7 BTRFS drives but on a standard sata HDD, usually running Reiser4.12 or higher instead of ReiserFS (or the file system can be Ext4 if needed), and swap space is on that mechanical HDD. For that SATA OS boot drive (SDA1) for Linux, even a 50pence 20GB HDD from an xbox360 2nd hand would do. Eventually, extra features might be added where a local electronics repair shop (or technology magazine with paid subscription in bilingual English language and Filipino like Tagalog) sponsers a particular education program (e.g. computing law or electronics repair and HAM Radio with music games sold) so adverts for it are shown with a hyperlink.

    I would say that students get a multivitamin (iodine salts etc and vitamin C) as a bottle of (low cost) vitamin pills (1 a week) sent to their family once per academic year and they (like paying adults or companies who use the ISP) get HowTo wiki tutorials on prepping (making your own G-O-O-D-Bag, first aid and DIY, including how to use the Man-pages for advanced users). And no, familes and companies cannot "blag the students internet" to do personal internet. The could however have access to educational health "atom" feeds downloaded by the students automatically, probably in some GTK4 app. The RSS feeds would have everything you find on a teletext style system anyway including stocks and shares. A teacher would probably volunteer answers to an FAQ anyway once in a while. A parent or company cannot blag the student internet for say their own internet banking. Thereby, private companies (capitalism) should still have its area in which to grow.

    As for recommending Google (not just Microsoft and Red Hat and Apple) for linux/BSD (or 'nix based systems) deployment... Hmm well I would think about it. I will use the google-map screenshot to show there might be hope for google to be fair but I will discourage the use of google for this until they release this comment (basically identical to this post written here) because they have deployed a system that has hidden the comment. This laser internet and Wifi could actually be made by a community (via a whipround) instead of State and large company involvement and so a large company should feel happy at being invited into such a solution. This laser-wifi internet solution is about avoiding downtime so people can comment, and send-receive information, not to induce downtime artificially by making comments like this hidden.

    See this video on youtube for an alternative to using the laser because it is a (Wifi Device Rocket AC Gen2 with 25KM) wifi alternative (instead of using any laser) using the 802.11ac standard even though thet 802.11g standard could be converted at hubs between these links made by the Wifi Device Rocket AC Gen2 with 25KM.

    The internet laser connects in series, using some of its (thus far about half a gigabit bandwidth), but where laser is not available a fairly low cost Wifi device could be used across that long 25KM stretches of water (or less distance) thereby daisy-chaining mutiple such (Rocket AC Gen2 ) wifi links together. A 25KM stretch of water is between Rosario-Noveleta to the Eastern side of Manila Bay and the Western side ALAS_asin to the coast near Mount Mariveles. The Wifi device would span that 25KM and achieve 150MBps (if using WiFi 802.11AC) speeds and two such Wifi device pairs of dishes would double that bandwidth to give 300Mbps and by then only about 250Mbps would be needed unless the extra 50Mbps in the 300Mbps were used to create and 11th purple circle hub to expand beyond Sasmauan Municipal Hall to the north or instead, to expand far South, to link Old Lighthouse at Montemaria, Batangas, across the water to (a new purple circle Wifi Hub) Sabang Ferry Terminal which is connected by road to Puerto Galera Bayan Oriental Mindoro, so the Wifi would connect its signal over a stretch of water under 25KM, reaching the Island that has Mounts Iglit Baco National Park on it. The Purple Circle hub of Sabang Ferry Terminal would convert back to a 802.11g 54Mbps Wifi once again. since thet populationis lower in density, that 54Mbps of wif could be split into several links instead of using it all on an extra 400 students there and so, instead a few hubs link to some other Calamian islands, so each new purple circle hub tat far South would each exist whilst having say 50 to 100 students only (at 128kbps), so that way between 4 and 8 of the islands could get an internet connection from that Wifi Rocket AC Gen2 device. If that were done, the (Rocket AC Gen2) signal series would probably go next via the Island with Marinduque on it to then connect to Banton Island and then Tabias Island and over water to Northwest Panay Peninsula Natural Park and (with more such Rocket AC Gen2 wifi links) it would probably be able to get to Cebu City, Lungsod, then Samar Island and Surigao City Port & Ferry Terminal, Port Area, Surigao City, Surigao del Norte, Philippines. All this is still on the half a Gigabit connection. If it were to work, the South Islands or the North could use another half Gigabit perhaps, thereby creating the entire nework on solely 1 Gigabit of a connection.
