The document describes the evolution of 3G mobile systems with the introduction of High Speed Downlink Packet Access (HSDPA). HSDPA will enhance 3G by offering higher data rates in the downlink direction through the use of new physical channels, adaptive modulation, Hybrid Automatic Repeat Request, and fast packet scheduling controlled by the Node B. The introduction of HSDPA will occur in phases, with the first phase introducing basic HSDPA functionality and the second phase enhancing it further through the use of technologies like MIMO. HSDPA aims to improve spectral efficiency and support high-speed data services for mobile users.
HSPA+ Seminar Presentation
The document provides an overview of High Speed Packet Data Evolution (HSPA+). It discusses the goals of HSPA+ to achieve performance comparable to Long Term Evolution (LTE) with a bandwidth of 5MHz. The key techniques discussed to achieve these goals include Multiple Input Multiple Output (MIMO), higher order modulation up to 64QAM, control channel improvements, and protocol optimizations. In conclusion, the combination of these techniques allows HSPA+ to reach close to LTE performance targets, though some targets like lower latency may not be achievable due to the longer transmission time interval of HSPA+.

DC-HSPA+ is a mobile broadband technology that aggregates two 5MHz carriers to provide download speeds of up to 42Mbps. It doubles the speed capabilities of HSPA+ by using dual carriers for the downlink, with one carrier acting as an anchor and the other as supplementary. This allows users to be served using two carriers simultaneously instead of one as in HSPA+, effectively doubling throughput. DC-HSPA+ also provides benefits like carrier load balancing and backward compatibility with earlier 3G releases. Real-world tests showed speeds were doubled compared to HSPA+ alone.

An analysis of the WCDMA Enhanced Uplink. Key features, achievable bitrate performance and suitability to practical network topologies.
Published September 2007.
High Speed Packet Access
The High Speed Packet Access technology is the most widely used mobile broadband technology in communication world. It was already built in more than 3.8 billion connection with GSM family of technologies. The HSPA technology is referred to both High Speed Downlink Packet Access (3GPP Release 5) and to High Speed Uplink Packet Access (3GPP Release 6). The Evolved HSPA technology or HSPA + is the evolution of HSPA that extends operator's investments before the next generation's technology 3GPP Long Term Evolution (LTE or 3GPP Release 8). The HSPA technology is implemented on third generation (3G) UMTS/WCDMA network and accepted as the leader in mobile data communication.
Using the HSDPA optimization on downlink is performed, whereas the HSUPA technology applying Enhanced Dedicated Channel (E-DCH) sets some improvements for the uplink performance optimization. The products that support HSUPA became available in 2007 and the combination of both HSDPA and HSUPA were called HSPA. Adopting these technologies the throughput, latency and spectral efficiency were improved. Introducing HSPA resulted to the increase of overall throughput approximately to 85 % on the uplink and a rise more than 50 % in user throughput. The HSPA downlink available rates are 1 to 4 Mbps and for the uplink are 500 kbps to 2Mbps as of 1 quarter of 2009. The theoretical bit rates are 14Mbps at the downlink and 5.8 Mbps at the uplink in a 5MHz channel. Besides, the latency is notably reduced as well. In the improved network, the latency is less than 50ms, and after the introduction of 2ms Transmission Time Interval (TTI) latency is expected to be just 30ms.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

HSPA AND HSDPA
- 1. By: Aishwarya Wankhade (16314) Vineet Raul (16024) Pushakraj Tambat (16023) Darshana Kawalkar (16111)
- 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
- 6. Advancement of HSPA Evolved of HSPA (HSPA+) Multiple Input Multiple Output Technology Higher Order Modulations Multi Carrier Technology
- 10. HSUPA Throughput & Users 0 20 40 60 80 100 120 140 160 WCDMA - Release 99 (CS) HSPA - Release 6 (VoIP) HSPA - Release 7 (VoIP) USERS RELEASES AMR - 12.2 Kbps Uplink 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)
- 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.
