Amazon has presented three different antennas for its satellite internet, including a compact model with an edge length of just 17.8 cm and a weight of less than half a kilogram. Internet speeds of up to 100 Mbit/s are expected to be achieved with this model, which makes it attractive for customers on a budget, but also for government agencies and companies that want to connect Internet of Things (IoT) devices.
The largest antenna that Amazon will offer for its satellite internet measures approximately 48 x 76 cm and offers a maximum speed of one gigabit per second. This model is intended for large companies, government agencies and telecommunications providers that require higher bandwidths than the other two variants offer.
A baseband chip developed by Amazon called “Prometheus” forms the basis for all three antenna models. The chip is said to combine the performance of a 5G modem chip found in current smartphones with the capabilities of a cellular base station capable of handling thousands of simultaneous connections. The Prometheus chip will also be deployed in Amazon’s Internet satellites and in gateway antennas on Earth to process Internet traffic at speeds of up to one terabit per second.
