7/21/2023 0 Comments Downlink definitionThe latest experiments on HSPA downlink speeds carried out by Ericsson in laboratory conditions have been able to reach up to 168 Mbps. Downlink is a telecommunication term pertaining to data which is sent out or downwards from a higher level or portion of a network. This is faster than some of today’s land-based broadband connections. In the second phase, HSDPA systems will be able to achieve up to 42 Mbps data rates. For example, a device with category 6 can have a 3.6 Mbps downlink rate, while a category 8 device can achieve a 7.2 Mbps downlink.Īs of this writing, HSDPA deployments are still part of the first phase. The downlink speed of an HSDPA device will depend on its category number. However, it is worth noting that not all devices that support HSDPA feature the same downlink speeds. Earth Station Uplink It is the process in which earth is transmitting the signal to the satellite and satellite is receiving it. adjective pertaining to such transmission. Top-notch smartphones like the Apple iPhone 4, Nokia N8, BlackBerry Storm 2, HTC Desire S, and LG Optimus 2X support HSDPA. 17.7 21.2 GHz downlink This range of frequencies is subject to various regulatory procedures. downlink doun-lingk See synonyms for downlink on noun a transmission path for data or other signals from a communications satellite or airborne platform to an earth station. This is also the reason why HSDPA systems are being deployed way ahead of their HSUPA counterparts. The high bandwidth, a far cry from the grainy footage captured during the Apollo missions 50 years ago, could enable high-definition views of the moon in real time. This link may be an actual physical link or it. However, since HSPA network end users perform more downloads than uploads, HSDPA speeds are naturally much higher than HSUPA. «Downlink» In telecommunications a link is a communications channel that connects two or more communicating devices. While HSDPA focuses more on high downlink speeds, HSUPA is designed for high uplink speeds. HSDPA is just one half of the HSPA family. Also, as it is a result of 3GPP initiatives, HSDPA is geared towards evolved GSM core networks. It is being standardized by the 3rd Generation Partnership Project (3GPP). Techopedia Explains High-Speed Downlink Packet Accessīeing part of HSPA, HSDPA is a result of enhancements made on UMTS (Universal Mobile Telecommunications System). The networks are then to be upgraded to Evolved HSPA, which provides speeds of 42MBPS downlink in its first release. the amount of data that can be received and written to the storage medium or the amount of data read from media and returned to the requesting system. In the near future these speeds should increase greatly. Current HSDPA deployments support down-link speeds of 1.8MBPS, 3.6MBPS, 7.2MBPS and 14.4 MBPS.
