Introduction:

HSDPA, short for High-Speed Downlink Packet Access, is a new protocol for mobile telephone data transmission. It is known as a 3.5G (G stands for generation) technology. Essentially, the standard will provide download speeds on a mobile phone equivalent to an ADSL (Asymmetric Digital Subscriber Line) line in a home, removing any limitations placed on the use of your phone by a slow connection. It is an evolution and improvement on W-CDMA, or Wideband Code Division Multiple Access, a 3G protocol. HSDPA improves the data transfer rate by a factor of at least five over W-CDMA. HSDPA can achieve theoretical data transmission speeds of 8-10 Mbps (megabits per second). Though any data can be transmitted, applications with high data demands such as video and streaming music are the focus of HSDPA. HSDPA improves on W-CDMA by using different techniques for modulation and coding. It creates a new channel within W-CDMA called HS-DSCH, or high-speed downlink shared channel. That channel performs differently than other channels and allows for faster downlink speeds. It is important to note that the channel is only used for downlink. That means that data is sent from the source to the phone. It isn't possible to send data from the phone to a source using HSDPA. The channel is shared between all users which lets the radio signals to be used most effectively for the fastest downloads.

Audience:

Engineers, technicians and other technical professionals requiring a technical foundation in UMTS systems and technology. The course is particularly valuable for those who are in the process of converting from current 2G technologies (for example GSM) to 3rd Generation systems, and those who will be working closely with UMTS in a technical capacity.

Prerequisites:

Basic Knowledge of radio principles and basic modulation techniques, along with a current mobile communications system.

Customize it:

This 2-3-day HSDPA course will be customized to your needs and specifications. Enowireless will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Enowireless, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”, one size fits all, class.

Objectives:

This course provides you with a comprehensive business and technical foundation in HSDPA migration paths, services and applications development. It offers an overview of the High Speed Downlink Packet Access (HSDPA) technology. HSDPA enhances the packet data services provided in W-CDMA (UMTS) by increasing the data throughput and reducing unwanted delays and it allows carriers to increase downlink throughput over W-CDMA links.
