Course description
Most mobile carriers find themselves planning and operating multi-generation networks on multiple and split frequency bands. What strategy should they apply to achieve an optimally performing composite radio network? How should the GSM, UMTS and LTE networks be planned with respect to the different technologies and the different frequency bands? How should the layering be performed? The LTE radio functionality and the integration options with existing mobile radio systems are described. Furthermore, interworking options with- and fall-back to/from GSM and UMTS systems are discussed. The opportunities offered by new regulatory framework that allows for frequency re-use are described by means of migration scenarios (spectrum re-farming). The course is relevant to strategic decision makers and radio planners who require better understanding of LTE radio planning and its implications on the existing radio plans and mobile infrastructure.
Target audience
The primary target audience is Radio Network Planners, Optimizers and strategy decision makers
