Internet Access in Cuba: From Control to Constellations

Internet Access in Cuba: From Control to Constellations

The first internet connection in Cuba was established in 1996 as a 64 Kbps link via Sprint in the United States. In 2011, with help from Venezuela, Cuba installed the ALBA-1 undersea fiber-optic cable, which became publicly usable in January 2013, replacing the old satellite backbone. From December 6–8, 2018, ETECSA rolled out mobile internet over 3G for Cuban cellphone users. By the end of 2019, an estimated 7.1 million Cubans were online in some capacity, as mobile data began to take hold. In 2023, the Arimao undersea cable, built with France’s Orange, was completed, linking Cuba to Martinique and

Téléphones satellites : un rapport complet

Iridium est une constellation LEO de 66 satellites actifs, qui a lancé le service en 1998 et a déployé Iridium NEXT en 2019 pour améliorer la couverture mondiale et les débits. Globalstar est un réseau LEO de 48 satellites, dont 24 satellites de seconde génération déployés depuis 2013, et ses satellites fonctionnent comme des répéteurs « bent pipe » sans liaison inter-satellites, ce qui peut limiter la couverture en mer. Inmarsat exploite une flotte GEO d’environ 11 satellites et couvre quasi-globalement en dehors des pôles; le terminal IsatPhone 2 est l’un de ses produits phares, et en 2023 Viasat a

This Common Phone Feature Could Land You in Jail Abroad: Inside the Global Crackdown on GPS and Satellite Phones

India bans unlicensed satellite communication and navigation devices, including Thuraya and Iridium phones and Garmin InReach, under the Indian Telegraph Act (1885) and Wireless Telegraphy Act (1933), with penalties up to three years in prison or ₹5 million in fines, and limited DoT licensing for Inmarsat devices. The 2008 Mumbai attacks involved a Thuraya satellite phone, prompting India’s tougher crackdown on civilian satphones. In March 2025 at Delhi’s Indira Gandhi International Airport, three American travelers and one Australian were booked under Indian telecom laws for carrying Garmin GPS units and an Iridium satphone.

Teléfonos Satelitales: Un Informe Integral

Los teléfonos satelitales se conectan directamente a satélites en órbita para voz, mensajes de texto y datos de baja velocidad, y pueden funcionar prácticamente en cualquier lugar siempre que haya línea de visión al cielo, sin depender de torres terrestres. Se presentan en tres tipos: portátiles, de instalación fija y marinos/aviación, con ejemplos de Iridium, Inmarsat y Thuraya para uso en campo. Las redes GEO orbitan a 35.786 km de altura y ofrecen una latencia de aproximadamente 0,6 segundos, mientras las constelaciones LEO (p. ej., Iridium y Globalstar) cuentan con 40–70 satélites y una latencia de 50–100 ms.

Satelliettelefoons: Een Uitgebreid Rapport

Satelliettelefoons maken rechtstreeks verbinding met satellieten in een baan om de aarde en bieden spraak, sms en data overal, mits vrij zicht op de lucht. Geostationaire (GEO) netwerken bevinden zich circa 35.786 km boven de evenaar, kunnen grote delen van de aarde dekken maar hebben hogere latentie (ongeveer 0,6 seconden) en bieden doorgaans meer bandbreedte; bekende netwerken zijn Inmarsat en Thuraya. Low Earth Orbit (LEO) netwerken bestaan uit tientallen tot honderden satellieten en bieden wereldwijde dekking met lage latentie, voorbeelden zijn Iridium NEXT met 66 actieve satellieten en Globalstar met 48 satellieten.

Where Satellite Phones Are Illegal?

Dove sono illegali i telefoni satellitari?

Bangladesh: tutto l’uso di telefoni satellitari è illegale, e il possesso può portare a arresto e detenzione. Ciad: i telefoni satellitari sono illegali in genere, con Thuraya vietato e Iridium tollerato solo in parte, quindi i viaggiatori non dovrebbero fare affidamento su questa distinzione. India: i telefoni satellitari sono ammessi solo se operano sulla rete Inmarsat approvata dal governo e registrati con una licenza DoT (NOC); gli stranieri con dispositivi non autorizzati sono stati arrestati e multati. Cina: l’uso privato di telefoni satellitari è vietato da decenni e oggi è consentito solo tramite operatori statali autorizzati; i segnali non registrati

Téléphones satellites : FAQ mondiale complète

Téléphones satellites : FAQ mondiale complète

Un téléphone satellite (satphone) se connecte directement à des satellites et nécessite une vue dégagée vers le ciel, avec une antenne proéminente généralement déployée à l’extérieur. Le signal est relayé par les satellites jusqu’à une station terrestre, avec une latence plus élevée sur les GEO (~0,5 seconde aller-retour) que sur les LEO (~50–150 ms). Iridium est un réseau américain de 66 satellites en orbite basse (~780 km) offrant une couverture mondiale véritable, y compris les pôles. Inmarsat est un réseau GEO composé de 3 à 4 satellites à ~35 786 km d’altitude, couvrant presque tout le globe sauf les pôles

Where Satellite Phones Are Illegal?

Bangladesh bans satellite phone use; possession can lead to arrest and imprisonment. North Korea prohibits all unauthorized communication devices, foreigners must surrender phones and privacy is not guaranteed, with detention possible. India restricts satellite phones to government‑approved Inmarsat devices, requiring a license (No Objection Certificate) from the Department of Telecommunications before bringing one in. China maintains a de facto ban on private sat phones, requiring registration for limited state use and has deployed jammers in some areas to block unapproved devices. Chad bans satellite phones under any circumstances, with Thuraya explicitly outlawed and Iridium sometimes tolerated. Myanmar (Burma) effectively bans

U.S. seizes Venezuela’s Maduro after strikes, setting up oil and diplomacy fallout

U.S. forces captured Venezuelan President Nicolas Maduro and his wife in a raid Saturday, detaining them in New York on drug charges. Venezuela’s government called the move a kidnapping and named Vice President Delcy Rodriguez interim president. Oil exports stalled as tankers remained docked and PDVSA halted some operations. Defense Minister Vladimir Padrino said much of Maduro’s security detail was killed in the operation.

Guyana’s Internet Boom: From Slow Starts to a Surging 2025 Connectivity Revolution

Guyana’s Internet Boom: From Slow Starts to a Surging 2025 Connectivity Revolution

Overview of Internet Infrastructure in Guyana Guyana’s internet infrastructure has evolved from rudimentary beginnings into a more robust, modern network. The country – sparsely populated and covered in rainforest outside its coastal strip – long relied on a limited telecommunications setup. Until the 2000s, most Guyanese accessed the internet via dial-up or very slow broadband over copper phone lines. Today, that picture is dramatically different. Fiber-Optic Backbone: Guyana now boasts multiple fiber-optic cables carrying data domestically and internationally. One Communications (formerly GTT) and other operators have laid fiber routes along the populated coast and across parts of the interior. Notably,

Starlink Goes Dark-Busting in Iran: How Elon Musk’s Satellite Beams Shattered Tehran’s Internet Blackout and Triggered a Global Free-Speech Showdown

Starlink Goes Dark-Busting in Iran: How Elon Musk’s Satellite Beams Shattered Tehran’s Internet Blackout and Triggered a Global Free-Speech Showdown

On 13–14 June 2025 Israeli strikes hit Iranian nuclear and missile sites, driving Iran’s internet speeds below 15% of normal per NetBlocks, and within about 24 hours SpaceX activated Starlink in Iran with Elon Musk posting „The beams are on.” Starlink operates 6,300-plus satellites at roughly 550 km altitude, making Iran unable to sever fiber backhaul or submarine cables to block the service. An estimated 20,000 dishes were already scattered across Iran before the crisis due to underground smuggling networks. Recent direct-to-device tests let ordinary phones send SOS messages through Starlink even without a dish. Iranian state media warned citizens
