Advanced Level 1 PIM Certification

Introduction:

Passive Intermodulation (PIM) testing is now a standard for radio site commissioning and certification. PIM has been around since the beginning of radio communication and has become a major performance issue for wireless carriers in recent years. Wireless broadband and 4G networks, utilities, government agencies and private users are converging to higher data rates with higher spectral bandwidth requirements, which all drive the necessity to reduce PIM at radio sites.  Wireless carriers now require PIM testing and certification of all new sites as well as testing existing installations in an effort to increase call quality and reduce lost data.

Effective PIM testing requires knowledge, practical skills and appropriate tools. Kaelus and OnPoint Testing now offer on-site training workshops to teach engineers, technicians and installation crews the skills needed to construct and maintain "low PIM" RF infrastructure.

This One Day Course is moderately technical and does not require prerequisites although prior radio or installation experience is a plus. The student will learn what PIM is, how it is tested and the difference between PIM testing and other antenna testing techniques. This course is more than 50% hands-on with test equipment, site RF network simulations, and verifications associated with instrument operation.
