Full description
JCdrawn is a YCombinator Certified Startup, and also we were 2016, 2017 shortlisted on Wireless Broadband Alliance's WGC annual industry awards. WBA launched OpenRoaming in 2020, that makes login unvisited WiFi automatically, and DoubLinks as a Multi-Path VPN service combining WiFi and Cellular data in realtime to make a Video/Audio Call Seamless, Secure and Reliable, will be the Best to leverage with. ****Notice 1**** As a Free run, we request for your email to sign up, so we can maintain your account, to refuel 5 GB FREE data per month into it. ****Notice 2**** To run DoubLinks as a Multi-Path VPN service with 2 active Links, Mobile and WiFi, you need to Enable “Cellular Data Always Active” mode on Android by doing following steps, and also you need to permit VPN service on your phone. 1. Go to Settings » About phone » scroll to the bottom and tap on Build number seven times to enable Developer options. 2. Go back to Settings page and select “Developer options” from here now. Scroll down a bit and you’ll see “Cellular Data Always Active” toggle under Networking options. 3. Enable it and you’ll have Mobile active even when WiFi is also active. That’s the basic to run DoubLinks. ****Tips**** If you prefer WiFi than Mobile, you can check the First switch for WiFi, it will make WiFi be prioritized than Mobile to send data over. Vice versa, if Mobile than WiFi. Or let them both unchecked with same priority. ****Introduction**** In our daily environment, at times we probably don't have good enough connectivity to do things with good quality, especially so called LIVE APPLICATION, such as Online Game, Live Streaming and Virtual Meeting. Most of the time, it's because WiFi is not as good as we need, since it's run on unlicensed frequency. Can we make the experience better? Yes, because we also have Mobile link on our smartphone, what if we can combine the 2 links together to make a much stronger link? with each of them augmenting the other at runtime. When the WiFi getting weak in signal or congested according to capacity problem, Mobile can fill in the "bullets" (packets capacity) in real time, just fix the gap. Yes, someone may say some source already provides the solution, so far been known, even it'd been true provided, most of them were like kind of REDUNDANT mode, that means duplicate each packet an Application generated down to both path. It's flooding the NETWORKS, especially in a time that network resources are both critical assets on Mobile and WiFi networks. DoubLinks as a Multi-Path VPN service, combines Mobile and WiFi data in a LOAD BALANCE way, so the effect is WiFi and Mobile augments each other to make the link Best: More Seamless, Secure and Reliable with less Glitch and Lag. OK, what scenarios DoubLinks are for? Most of them are the times you doing LIVE. Virtual Meeting: You probably do it at indoor, if you experience WiFi not always good enough by seeing the video/audio performance fluctuate a lot, then please check if you can see couple grades that Mobile signal icon shows on your phone, if it does, then it's time to use DoubLinks, let Mobile augment WiFi for you. Going Live: Your kids have a baseball game taken place in the afternoon, You want Live the kids to grand pa on the other side of the country. Ok, it's typically at outdoor, please make sure if your spouse or friend willing to share their Mobile data (best from other operator) by hotspotting his or her smartphone, so you get a WiFi link, then you can let DoubLinks combine the WiFi with your own Mobile to make the Live best. Online Game: Hey, probably you'd say it's one of the most critical time you want Link best, otherwise you got killed by doing nothing wrong, just because the WiFi or Mobile stuck. Yes, just in case the link would go wrong, so you could have precluded WiFi or Mobile before you play. Hah, it's time you let DoubLinks combine them for you :) Facebook page: https://www.facebook.com/DoubLinks-APP-usergroup-111892553921880/
