Introduction:

High Speed Uplink Packet Access (HSUPA), a technology that complements High Speed Downlink Packet Access (HSDPA), is an evolutionary step that makes the uplink of WCDMA packet-based for data services. Together, HSDPA and HSUPA offer reduced latency and much higher data rates on the downlink and uplink, theoretically as high as 14.0 Mbps in the downlink and up to 5.8 Mbps in the uplink. They are expected to help usher in a mass market for mobile IP multimedia services.

Audience:

Radio design engineers, 3G applications developers, radio network planners, system architect and designer, programmers, system engineers, and technical managers

Customize it

This 2-3-day 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.

Course Objectives:

In this course, you will undertake a comprehensive review of the layer 1 and layer 2 protocol functionality introduced in the UTRAN to support HSUPA, also known as Enhanced DCH or E-DCH. We will pay particular attention to the new Medium Access Control protocol entities, namely MAC-hs, MAC-e, and MAC-es. We will study in depth the functionality and coding of the new transport and physical channels, e.g. E-DCH, E-AGCH, and E-HICH. We will discuss how HSUPA impacts the UTRAN architecture as well as the key considerations involved in the planning of HSUPA networks. We will conclude the course with a look at the future of HSUPA and WCDMA.
