What is HSDPA explain the channels in HSDPA?
HSDPA enables much higher speed data transfer and one reason it can achieve it is because of new channels that have been added. The three main channels are High Speed Downlink Shared Channel, HS-DSCH; High Speed Signalling Control Channel, HS-SCCH; and High Speed Dedicated Physical Control Channel, HS-DPCCH.
Which modulation technique is used in HSDPA?
HSDPA 16QAM use As a result the 16QAM modulation format is normally used under high signal conditions, e.g. when the mobile is close to the NodeB and in the clear. The coding rate as well as the modulation are then selected for each 2ms TTI by the NodeB according to its assessment of the conditions.
What is HSDPA network?
High-speed downlink packet access (HSDPA) is a mobile communications protocol that belongs to the high speed packet access (HSPA) family. HSDP allows networks based on (UMTS) to have higher data transfer speeds. Current HSDPA deployments support down-link speeds of 1.8MBPS, 3.6MBPS, 7.2MBPS and 14.4 MBPS.
What is the importance of the HSDPA?
HSDPA helps reduce time delay in data transmission and improves system throughput. It optimizes system spectrum efficiency. It is also true that experience of using HSDPA is very similar to that of using fixed-line ADSL service.
Is HSDPA a CDMA?
HSDPA represents High Speed Downlink Packet Access while HSUPA stands for High Speed Uplink Packet Access. Although the HSPA uses 3G standards, it delivers higher data transmissions when compared to the CDMA technologies. HSPA was primed at improving 3G standards on CDMA communication protocol.
Is HSDPA the same as UMTS?
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.
How do I setup my HSDPA modem?
How to Install an HSDPA USB Modem
- Purchase an HSDPA USB modem.
- Sign a contract or activate a 3G network plan with a service provider.
- Turn on the computer and plug the HSDPA modem into an available USB port.
- Use the modem to access high-speed Internet connections through the service provider’s cellular 3G network.
