Training Course Outline
Course Duration:
3 Days
Training Course Description:
With 3G mobile technology already rolled out by over 200 operators in over 80 countries, preparations are well under way to create the next generation of mobile technology.
The UMTS standards body, 3GPP, has been following its plan to achieve ambitious goals for the future of mobile communications.. This is Long Term Evolution – LTE. Work on this is contained in Release 8 of the 3GPP Specifications. A headline goal is 100 Mbps in the downlink and 50 Mbps on the uplink, representing roughly a ten-fold improvement on HSDPA today.
This in-depth course covers all aspects of LTE, from the environment and forces shaping it, the physical changes involving MIMO antennas and the move from CDMA to OFDM, through the logical air interface channels to the necessary architectural and core network changes. Some specific aspects such as security and handover to non-3GPP technologies are included.
At the end of this course, delegates will:
- Understand the mobile
arena and the goals of LTE
- Appreciate the
evolutionary path towards LTE
- Be aware of major air
interface features including SC-FDMA
- Gain an understanding
of the radio channels at both physical and logical
levels.
- Know the principles of
LTE security.
- Appreciate the
manoeuvreings between LTE and Mobile WiMAX
