E2E4: blbě čtu, pardón. Akutní bezkafetida.

E2E4: vsak 5G standard pocital s podporou non-terrestrial networks od zacatku a prakticky se resi od Rel16 a 17 :)

SATAI: dyt říkám

PER2: se divim že tohle vůbec funguje.

jako jasné, GPS taky jde do mobilu až že satelitu, akorát že tam mobil nemusí vysílat až do vesmíru, jen přijímá, takže se to na zem praží velkým výkonem a tím pádem do mobilu něco velmi slabého dopadne, když je prima viditelnost.

akorát že tady i vysíláme, je to nad limit vzdálenosti sítí se kterým jsou schopny kompenzovat posun, satelit slyší mnoho mobilů na stejný frekvenci, navíc se pohybuje..

On Monday, January 8, the Starlink team successfully sent and received our first text messages using T-Mobile network spectrum through one of our new Direct to Cell satellites launched six days prior. Connecting cell phones to satellites has several major challenges to overcome. For example, in terrestrial networks cell towers are stationary, but in a satellite network they move at tens of thousands of miles per hour relative to users on Earth. This requires seamless handoffs between satellites and accommodations for factors like Doppler shift and timing delays that challenge phone to space communications. Cell phones are also incredibly difficult to connect to satellites hundreds of kilometers away given a mobile phone’s low antenna gain and transmit power. Starlink satellites with the Direct to Cell payload are equipped with innovative new custom silicon, phased array antennas, and advanced software algorithms that overcome these challenges and provide standard LTE service to cell phones on the ground. As the global leader in rocket and satellite launch and manufacturing, SpaceX
is uniquely positioned to rapidly scale our Direct to Cell network and will rapidly launch a constellation of hundreds of satellites to enable text service in 2024 and voice, data, and Internet of Things (IoT) services in 2025.

PES: sloke = společnost

KOUDY: žádná čínská sloke není úplně soukromá ;-)

ja nejdriv myslel ze je to nejakej midjourney obrazek, ale googlil jsem to a je to real :)..nejaka cinska soukroma spolecnost. Ja jsem rad ze ten zavod o dobyvani vesmiru je v obratkach, ale uz bych konecne rad vic vesmirnejch stanic a nejakej vesmirnej hotel sakra. Jdu se zas mrknout na For all mankind.

JIMIQ: já myslím, že se časem na aliexpressu dočkáš :D
