What is HSDPA category?
HSDPA is also known as 3.5G and 3G+. It allows networks based on the Universal Mobile Telecommunications System (UMTS) to have higher data speeds and capacity. HSDPA was introduced with 3GPP Release 5, which also accompanied an improvement on the uplink providing a new bearer of 384 kbit/s.
What does HSDPA stand for?
High-Speed Downlink Packet Access
HSDPA (High-Speed Downlink Packet Access) – definition. An upgrade for UMTS networks that doubles network capacity and increases download data speeds by five times or more.
What is the difference between HSPA and HSDPA?
HSPA refers to the combination of high-speed downlink packet access (HSDPA) and high-speed uplink packet access (HSUPA). HSDPA allows data rates up to 14.4 Mbit/s in the downlink. HSUPA makes uplink data rates of 5.76 Mbit/s possible. Both features enable a maximum data rate of 42.2 Mbit/s in the downlink.
What HSPA stands for?
high-speed packet access
Technology Overview UMTS provides a clear evolutionary path to high-speed packet access (HSPA). HSPA refers to the combination of high-speed downlink packet access (HSDPA) and high-speed uplink packet access (HSUPA). HSDPA allows data rates up to 14.4 Mbit/s in the downlink.
Is HSDPA the same as UMTS?
UMTS has a theoretical maximum data transfer of 21 Mbits/s (in the HSDPA form). UMTS is a 3G telecommunications technology that makes use of the W-CDMA, as well as other permutations therein; HSDPA is part of the 3G network, but is part of the High Speed Packet Access family, therefore capable of elevated performance.
What is the difference between HSPA and WCDMA?
High Speed Packet Access ( HSPA) is an amalgamation of two mobile protocols, High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), that extends and improves the performance of existing 3G mobile telecommunication networks using the WCDMA protocols.
What’s the difference between HSPA + and HSDPA modem?
The devices which support these technologies are called HSDPA modem and HSUPA modem. Both HSDPA and HSUPA falls under HSPA. HSPA+ supports speeds of 84Mbps in the downlink and about 23Mbps in the uplink. HSPA+ follows 3GPP R7,R8 and R9 standards.
What’s the average speed of a HSDPA connection?
In addition, the popularity of HSDPA landline replacement boxes grew—providing HSDPA for data via Ethernet and WiFi, and ports for connecting traditional landline telephones. Some are marketed with connection speeds of “up to 7.2 Mbit/s”, which is only attained under ideal conditions.
What are the key features of HSDPA transmission?
HSDPA is based on shared channel transmission, and its key features are shared channel and multi-code transmission, higher-order modulation, short transmission time interval (TTI), fast link adaptation and scheduling, and fast hybrid automatic repeat request (HARQ).
