Presentation (tablet pc &hspa)

  1. 1. PRESENTATION ON HSPA AND TABLET PC
  2. 2. TABLET PC : (TAB)
  3. 3. CHOOSING A BRAND NEW COMPUTER  When it comes to choosing a brand new computer, there will be confusion.  WHY CONFUSION?? Because  The different types of computing devices that have been launched  With devices like the Apple iPad (iPad 2 also) launched in the market, which is a tablet pc.  So, an average consumer‟s question would be, “Should I buy a laptop or tablet pc?”
  4. 4. WHAT IS IN A LAPTOP?  A Laptop is a combined functionality of a desktop with the portability of a mobile phone.  You can take laptop everywhere and desktops are not.  Laptops have Wi-Fi, bluetooth, USB connectivity, web cameras and many more features can additionally be added in a less cost.  Applications: In business, entertainment, gaming, networking, name the sphere of use, there is a laptop for it.  You can install everything and anything onto a laptop.
  5. 5. WHAT IS IN A TABLET PC  Tablets are a powerful tool for enhancing your productivity and online experience.  A tablet PC, with the size and weight roughly between smartphones and laptops.  An important tablet feature to consider is “operating system”, otherwise known as a 'platform„.  There are currently three choices available for OS:  Android,  BlackBerry, and  Apple.
  6. 6. KEY HIGHLIGHTS OF THE CURRENT OPERATING SYSTEMS:  Android  True multi-tasking.  Full Adobe Flash support.  Strong integration across Google's rapidly growing services .  BlackBerry  Wireless connectivity to existing BlackBerry smartphones.  Full Adobe Flash support.  Seamless pairing with BlackBerry servers.
  7. 7. LAPTOP VS TABLET PC
  8. 8. COMPARING TAB WITH A LAPTOP:  Size.  Battery Life.  Productivity.  Hardware Connectivity.  Navigation.  Others: (Screen break risk, Hard Disk).
  9. 9. FINALLY CHOOSING BETWEEN A TAB AND A LAPTOP :  Based on your usage and needs.  If you are looking for a portable, efficient and smart device, then you should go for a “tablet PC”.  If you like a serious programming and similar other works, need software and hardware support, then “laptop” will suit you.
  10. 10. RELIANCE TAB
  11. 11. HSPA HIGH SPEED PACKET ACCESS
  12. 12. INTRODUCTION: • WHAT IS HSPA??  The upgraded version of WCDMA.  High Speed Packet Access (HSPA) is an combination of two mobile telephony protocols.  High Speed Downlink Packet Access (HSDPA)  High Speed Uplink Packet Access (HSUPA)
  13. 13. CONTEXT :  What WCDMA can do:  Deliver audio  Deliver wireless services  Deliver low quality video  Provide low data rate, low mobility virtual office at high price.  What HSPA can do:  Deliver audio  Deliver wireless broadband services  Deliver high quality video  Provide virtual office environment at low price.
  14. 14. HSPA  An extension of the UMTS packet air interface.  No modifications to the core network and Traffic classes.  Data rates upto 3.6 to 14.4 mbps theoretically.  Difference between HSDPA and WCDMA :  ~10x more spectrally efficient.  5x faster and lower latency of 70ms.  More data users per cell.  More content for high end users.
  15. 15. CONTINUE..  HSPA extends and improves the Performance of existing WCDMA protocols.  DATA RATES : HSPA supports increased peak data rates  up to 14 Mbit/s in the downlink  5.76 Mbit/s in the uplink
  16. 16. FEATURES OF HSPA :  Shared-channel transmission  A shorter Transmission Time Interval (TTI)  Modulation Scheme: 16QAM and 64QAM  Fast scheduling  Link adaptation
  17. 17. HIGH SPEED DOWNLINK PACKET ACCESS (HSDPA)  The first step required to upgrade WCDMA to HSPA is to improve the downlink by introducing HSDPA (2006).  The improved downlink provides up to 14 Mbit/s with significantly reduced latency  The channel reduces the cost per bit and enhances support for high-performance packet data applications.
  18. 18.  HSDPA is based on shared channel transmission.  Its key features are Similar as those of HSPA.  It also provides fast (HARQ).  Just a software update for most WCDMA networks. CONTINUE..
  19. 19. HSDPA DATA RATES IN OTHER COUNTRIES :  Singapore's three network providers M1, StarHub and SingTel provide up to 28 Mbit/s throughout the entire island.  The Australian provider Telstra provides up to 14.4 Mbit/s nationwide and up to 42Mbit/s in selected areas.  BPL and Tata DoCoMo provide speed of 21.1 Mbit/s nationwide while Reliance ADAE provides speeds up to 28.8 Mbit/s nationwide.
  20. 20. HIGH SPEED UPLINK PACKET ACCESS (HSUPA)  The second major step in the WCDMA upgrade process is to upgrade the uplink HSUPA (2008).  Upgrading to HSUPA is usually only a software update.  Enhanced Uplink adds a new transport channel to WCDMA, called the Enhanced Dedicated Channel (E-DCH).
  21. 21. CONTINUE…  An enhanced uplink provides various opportunities for a number of new applications including  VoIP  uploading pictures  sending large e-mail messages.  Also increases the data rate (up to 5.8 Mbit/s), the capacity, and also reduces latency
  22. 22. EVOLVED HIGH SPEED PACKET ACCESS (HSPA+)  Evolved HSPA (also known as: HSPA Evolution, HSPA+) 2009-2010.  Evolved HSPA data rates:  up to 84 Mbit/s in the downlink and  22 Mbit/s in the uplink.
  23. 23. OTHER TECHNOLOGIES OF HSPA:  Dual-Cell HSDPA (DC-HSDPA)  Dual-Cell HSUPA (DC-HSUPA)  Multi-carrier HSPA (MC-HSPA)
  24. 24. THANK YOU

Editor's Notes

  • WHY CONFUSION??It is not just because of the range of laptop/PC brands available in the market, but also because of the different types of computing devices that have been launched.
  • Note : You can browse the internet, create and share presentations, videos conference with clients, stay connected with corporate email, download books, games and videos, watch movies, share photos and much more with your tablet
  • Android True multi-tasking, meaning you can do multiple activities such as email, web surfing and video chat at one time on the same screen Full Adobe Flash support, allowing users the full rich experience of the entire internet Strong integration across Google's rapidly growing services such as the Android Marketplace, Maps, eBooks and more.BlackBerry Wireless connectivity to existing BlackBerry smartphones for real time access to email and calendar plus 3G access. This uses your existing data plan - so no incremental monthly charge for 3G connectivity Seamless pairing with BlackBerry servers allowing for enterprise level performance and security Full Adobe Flash support, allowing users the full rich experience of the entire internet
  • Note: A further 3GPP standard, Evolved HSPA (also known as HSPA+), was released late in 2008 with subsequent worldwide adoption beginning in 2010.
  • Note: It also reduces latency and provides 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 compared to original WCDMA protocols.
  • Shared-channel transmission: which results in efficient use of available code and power resources in WCDMAA shorter Transmission Time Interval (TTI): which reduces round-trip time and improves the tracking of fast channel variations16QAM and 64QAM (Quadrature Amplitude Modulation):which yields higher bit-ratesFast scheduling : which prioritizes users with the most favorable channel conditions Link adaptation: which maximizes channel usage and enables the base station to operate at close to maximum cell power
  • UMTS RELEASE 5
  • HARQ= HYBRID AUTOMATIC REPEAT REQUEST.
  • UMTS RELEASE 6.
  • UMTS RELEASE 7
  • Mumbai: 3G bidders are expected to upgrade their network capability to high speed packet access (HSPA) to cater to the huge mobile broadband demand in India, soon after the 3G auctions.HSPA could emerge as a choice for operators wanting to offer mobile broadband services to both urban and rural consumer and enterprise users.HSPA comprises HSDPA, HSUPA and HSPA+, defining the migration path of 3GSM/W-CDMA operators worldwide
