Ku波段
SES Broadband uses the Astra 3B communications satellite at the 23.5° east orbital position to handle uplinks and downlinks in both directions. A number of transponders are used for the hub-to-terminal downlink in the satellite TV downlink segment of the Ku band (10.70 GHz-12.75 GHz). The terminal-to-hub uplink to the satellite uses the uplink segment of the Ku band (14.00 GHz-14.50 GHz) and extended Ku band (13.75 GHz-14.25 GHz)
