"Speed" is latency and bandwidth.
Bandwidth is solved with phased-array antennas at a high carrier frequency (Ku/Ka?). The high carrier frequency allows for high (literal) bandwidth. However, the phased-array antennas are physically the same size as some smaller, lower frequency antennas are, and thus transmit/recieve more power. This stuff in general is called a link budget and is standard in satcom.
Latency is just satellites at a lower orbit. This is only possible now because:
1. Chip manufacturing can produce a cheap phased array antenna that's electronically steered to follow the satellite in low orbit.
2. Launch costs low enough it's economical to launch tons of satellites
