3. HSPA
• High Speed Packet Access (HSPA) is an amalgamation of
two mobile telephony 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 utilizing
the WCDMA protocols.
• A wireless access technology designed for increasing the
capacity of Internet connectivity from 3G mobile terminals

4. • HSPA evolution first introduced downlink counterpart called
HSDPA in Release 5.
• Uplink evolution followed later in Release 6 by the name of
HSUPA.
• HSPA was originally designed for non-real time traffic with
high transmission rate requirements.

5. Features-
• HSPA improves the end-user experience by:
• Increasing peak data rates to 14 Mbit/s in the downlink and
5.8 Mbit/s in the uplink
• reducing latency
• Providing up to five times more system capacity in the
downlink and up to twice as much system capacity in the
uplink, reducing the production cost per bit
• link adaptation in downlink

11. Evolved HSPA (HSPA+)
• Introduced in 3GPP Release-7
• Wireless broadband standard defined
in 3GPP Release 7 of WCDMA
• Backward Compatibility
• Data Speed of 22 Mbps
• DC-HSUPA – Release 9

12. HSPA (Uplink & Downlink)

13. Advantages of HSUPA:
• Higher Order Modulation
• Shorter Frame Size or TTI
• HARQ – Effective Retransmissions
• Low Latency
• Real Support for Multi-codes
• Fast Packet Scheduling
• Shared Channel Transmission

14. Disadvantages of HSUPA:
• Network Strength
• Number of Users
• Cost

15. HSDPA
• In WCDMA 3GPP Release 5, HSDPA adds a new transport
channel to WCDMA– the High Speed Downlink Shared
Channel (HS-DSCH) – which provides enhanced support for
high-performance packet data applications in the downlink.
• The improved downlink provides up to 14 Mbit/s with
significantly reduced latency. Current devices support 7.2
Mbps throughput.
• In order to support HSDPA features with minimal impact
on the existing radio interface protocol architecture, a
new MAC sub-layer, MAC-hs, has been introduced. It
enables a functional split to be retained between layers
and nodes from WCDMA 3GPP Releases 99 and 4.

16. Features Of HSDPA:
• Shared Channel and Multi-Code Transmission
• Higher-order modulation
• Short Transmission Time Interval (TTI)
• Fast link adaptation
• Fast scheduling
• Fast Hybrid Automatic Repeat request (ARQ)

18. Deployment of HSDPA:

19. Advantages Of HSDPA:
• The network can employ data schedulers that give higher
priority to real-time applications.
• Employs shorter frame length, thus it can react faster to
problems in the radio channel.
• Provides shorter delays, which enables new applications, such
as interactive networked games.
• It is best for applications with highly variable bandwidth
requirements.

20. Disadvantages:
• Not suitable for applications with low band-
width requirements, such as voice.
