HSPA (High-Speed Packet Access) is a wireless technology that improves 3G networks to provide faster data speeds for mobile internet access. It is made up of two protocols - HSDPA for faster downloads and HSUPA for faster uploads. HSPA provides download speeds of up to 14 Mbps and upload speeds of up to 5.8 Mbps, allowing users to transfer large files and stream content more smoothly with low latency. It uses advanced techniques like adaptive modulation and coding as well as fast scheduling and retransmissions. HSPA has continued to evolve through releases that deliver even higher speeds and additional capabilities.
HSPA es una tecnología de acceso inalámbrico que mejora la capacidad y velocidad de conexión a Internet desde dispositivos móviles 3G. Se han desarrollado incrementos de velocidad como HSDPA y HSUPA para permitir hasta 42 Mbps de bajada y 11 Mbps de subida. HSPA se ha implantado en más de 170 redes en 76 países y se espera que alcance los 700 millones de usuarios en 2012.
HSPA is a mobile telecommunications protocol that extends 3G networks by improving data transmission rates. It consists of HSDPA for faster downloads and HSUPA for faster uploads. HSPA was designed for non-real time data and increases peak rates to 14Mbps down and 5.8Mbps up. It achieves these improvements through technologies like shorter transmission time intervals, link adaptation, advanced modulation schemes, and MIMO antennas. The architecture introduces new channels like HS-DSCH for user data and HS-SCCH for control information. Subsequent evolutions like HSPA+ and DC-HSDPA have further increased speeds through higher order modulation and dual-cell connections.
The document discusses HSPA systems and provides an overview of High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA). It notes that HSPA was introduced to improve the packet data capabilities of WCDMA in response to growing interest in rich calls, mobile TV, and streaming services. HSDPA introduced faster scheduling, link adaptation, and hybrid automatic repeat request to improve downlink performance, while HSUPA later improved uplink performance using similar techniques. The document provides technical details on the channels, link adaptation, scheduling, mobility, and retransmissions used in HSDPA and HSUPA systems.
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+.
HSPA is a combination of protocols that extends 3G networks by improving downlink and uplink speeds. It aims to increase peak data rates up to 14.4 Mbps downlink and 5.8 Mbps uplink through technologies like shared channel transmission, shorter transmission time intervals, and link adaptation. HSPA+ is an advanced version that achieves data rates up to 42 Mbps downlink and 11 Mbps uplink using 64QAM modulation downlink, 16QAM uplink, MIMO, and continuous packet connectivity. The presentation provides information on HSPA technologies, peak data rates under different configurations, and applications for accessing and optimizing data.
HSPA evolution involves several new features to increase data rates:
1) MIMO (2x2) using spatial multiplexing allows two independent data streams to increase throughput.
2) Higher order modulations like 64QAM for downlink and 16QAM for uplink allow more bits per symbol.
3) Layer 2 enhancements like flexible RLC PDU sizes and MAC-ehs header format allow higher data rates to be supported.
The document provides an overview of LTE (Long Term Evolution) network architecture and transmission schemes. It describes the simplified LTE network elements including eNB, MME, S-GW and P-GW. It explains the downlink transmission scheme using OFDMA and reference signal structure. It also covers uplink transmission using SC-FDMA, control and data channels as well as frame structure in both FDD and TDD modes.
- HSUPA (Enhanced Uplink) improves the uplink capabilities of WCDMA networks by providing higher data rates, reduced latency, and improved system capacity. It complements HSDPA for downlink improvements.
- The NodeB scheduler controls UE uplink transmissions to manage interference levels. It uses scheduling requests and grants to determine each UE's allowed transmission power and data rate.
- In soft handover, the serving cell schedules transmissions while UE monitors grants from all cells to support HARQ and reliable transmission.
The document discusses HSPA MAC-centric technologies including HSDPA and HSUPA. It provides an overview of 3GPP UMTS evolution from Release 5 to Release 8, which introduced HSDPA and HSUPA to improve peak data rates and reduce latency. It describes key aspects of HSPA such as the location of MAC-hs at the Node B to enable fast scheduling and HARQ, as well as transport and physical channels used in HSDPA and HSUPA like HS-DSCH, E-DCH, HS-SCCH, and HS-DPCCH. It also covers flow control between the Node B and RNC and enhancements introduced in Release 6.

This document outlines a research proposal to evaluate schools participating in the HealthierUS School Challenge program in Illinois. The study aims to determine what factors predict schools' ability to make changes to improve nutrition and physical activity. It will survey school food service directors about school characteristics like income levels, location, and existing wellness policies. Analysis of responses may show relationships between these factors and schools' success in the Challenge program. The proposal provides background on childhood obesity issues and literature reviewing past studies on school food environments and implementation of nutrition standards.
