41. This important relationship between downlink precoding and uplink receive filtering is known as the uplink-downlink duality. 42. The C-band capacity permits Internet access with downlink capabilities of up to 15 Mbit / s. 43. A similar uplink capability did not exist because the uplink budget had far more margin than the downlink . 44. The downlink ( forward link ) and / or uplink ( reverse link ) directions may be monitored. 45. High-Speed Downlink Packet Access . talk ) 01 : 27, 30 April 2011 ( UTC) 46. In the downlink case, the transmitters and the receivers can be considered as two separate point processes. 47. The K u band has 249 transponder equivalent for a total downlink bandwidth of 9, 194 MHz. 48. The K u band has 39 transponder equivalent for a total downlink bandwidth of 1, 404 MHz. 49. If data traffic is concentrated in downlink direction the network will configure the connection for 5 + 1 operation. 50. The available bandwidth is only 512 kbit / s uplink, and 1.5 Mbit / s downlink .
