Why should I choose TONEX for RF Optimization Training?

RF Optimization Training Course provides a thorough overview of the principles behind RF optimization applied to GSM, EDGE, CDMA/CDMA2000, WCDMA/UMTS, LTE, Microwaves, SATCOM, VSAT and Wireless LANs/Hot Spots. This four-day course builds competence in the principles and present-day practices used to improve the operating performance of modern wireless systems. Core performance indicators are thoroughly explored and desirable healthy operating conditions are identified. Both system-side and mobile-side performance-monitoring tools are introduced. The main operating parameters are identified along with the considerations necessary to properly set them in real systems.

RF optimization training

Signatures of specific problems (including several deadly but innocent-appearing failure mechanisms) are identified, along with their common solutions. Real-life captured drive-test examples are studied and solved by the class. Special attention is given to multiple-carrier and intersystem handoff issues, system determination algorithms commonly used by mobiles, and data communication, and a glimpse of future issues. At conclusion, participants will be able to evaluate their own systems’ performance, armed with the knowledge and confidence necessary to identify and solve most common problems, definining KPIs and more.

Applicability:  Wireless LANs, Microwave Systems, Satellite Communications,VSAT, CDMA/CDMA2000 1x, 1xEV-DO, GERAN,UMTS (R99, HSPA/HSPA+), LTE and LTE Advance and any other RF systems.
