(This message was added in version 6.7.0.) in /home4/scienrds/scienceandnerds/wp-includes/functions.php on line 6114Source:https:\/\/techcrunch.com\/2023\/04\/28\/satellite-to-phone-race-heats-up-with-voice-calls-and-cross-canada-access\/<\/a><\/br> The prospect of contacting a satellite to send a text or contact emergency services may soon be an effortless reality as startups move from proof of concept to actual product. Canadians on the Rogers network, which just inked a deal with Lynk, will get direct satellite-phone connections across the country; and not to be outdone, AST SpaceMobile claims to have made the first satellite voice call using a regular cell phone as well.<\/p>\n Connecting a stock smartphone like last year\u2019s Samsung or iPhone to a satellite would have sounded like a fantasy a few years ago, when we all knew it was impossible. But now companies are jostling for position as it becomes clear that satellite services will be a compelling offering on any mobile plan or phone model over the next few years.<\/p>\n Lynk\u2019s approach is to offer as universal as possible an SMS service to as much of the planet as possible, in the hopes that no one who needs help or is off the grid for any other reason will ever have to face \u201cno signal.\u201d It has demonstrated texting from the middle of nowhere (in fact the founder texted me) and also can blanket an area unexpected without signal \u2014 due to a power outage or natural disaster \u2014 with crucial info like where to find shelter.<\/p>\n The company has been striking deals across the world with various carriers, and is now at the very doorstep of the U.S. (which has a tough regulatory environment and entrenched mobile players) with a deal with Canada\u2019s biggest provider, Rogers<\/a>.<\/p>\n Although the idea is that everyone will be able to use this, every satellite cellular station still needs to operate through a licensed carrier. The Rogers deal doesn\u2019t mean total exclusivity (for example, you\u2019re lost and need help but have a different carrier) but it is the carrier that is paying Lynk, and will take payment from customers across Canada as the local partner. I\u2019ve asked for more details on this and will update if I hear back.<\/p>\n Bringing a more comprehensive connectivity package to the table is AST SpaceMobile, which has launched its first test satellite and for the first time demonstrated a direct phone-to-satellite call<\/a> using an unmodified consumer handset. I double checked (this stuff can be tricky) and the connection was a continuous two-way data exchange between the phone and the satellite, which relayed it to the terrestrial network:<\/p>\n Abel\u2019s phone in Texas was connected directly to the satellite for both send and receive two-way communications, without any other intermediary. He made the phone call by typing in the number to the regular Samsung dial app on the Galaxy S22, just like you would make any regular phone call. The other end of the phone call in Japan was received via the normal terrestrial communications network (a cell tower).<\/p>\n<\/blockquote>\n Demonstrating the capability is a huge step forward, since the engineering involved in getting a regular phone to connect with something in low Earth orbit is already difficult \u2014 maintaining that connection to the point where data can flow constantly between them is even harder. Scaling is yet another problem that AST SpaceMobile will face, but having proven the capability, that challenge probably seems less daunting now.<\/p>\n The company\u2019s BW3 satellite is the prototype for a constellation that will provide \u201c2G, 3G, 4G LTE and 5G\u201d coverage from space, which is great because I lose 5G just going down the block. Help me out, AST SpaceMobile.<\/p>\n Of course Apple has made headlines with its emergency SOS service, which connects to the Iridium network but requires you to sort of sight your phone on a passing satellite in order to exchange a set of mostly premade messages. Useful if you\u2019re stuck in a canyon and need a helicopter to scoop you up<\/a>, but not if you want to check the weather or tell your spouse your backpacking trip is going fine.<\/p>\n
