State-of-the Art Satellite Communications - Technologies and Solutions Training


State-of-the Art Satellite Communications – Technologies and Solutions Training Course Description

Modern satellite communications networks and systems rely on innovations in both the radio frequency (RF) and baseband domains. Introduction and application of these cutting-edge technologies and processes are addressed by this in-depth three day course. Established during the last decade, technologies that make a difference include high throughput satellites, high power solid state amplifiers (up to one kW), array antennas for mobile platforms, channel linearization, turbo codes, DVB-S2 extensions and adaptive coding and modulation (ACM). The path forward involves the right choices in terms of which technologies and their introduction – and the use of integrating tools such as system simulation and optimization. Investments in new satellites, earth stations and network management systems need the right system-level view, and at the same time, demand a thorough understanding of the underlying details within the RF aspects (propagation, link availability and throughput) as well as the ability of baseband systems to provide throughput under expected conditions and to end users. The State-of-the Art Satellite Communications – Technologies and Solutions Training examines real options and makes use of quantitative analysis methods and systems analysis to evaluate the technology horizon.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
