4G Training & Certification

LTE is an OFDM broadband technology, with very wide channels. Narrow band channels present similar fading characteristics in its bandwidth, with variations restricted only to time dimension. Wide band channels vary in the frequency domain also. The designer has to have a full understanding of this variations and this information is not available with traditional test gear.


Until today designers had to guess multipath and fading performance, but the deployment of wide band channels and MIMO techniques require a precise understanding of this effect geographically.


Decisions as where to deploy cells, what number of antennas to use and parameter settings, can represent huge capital (CAPEX) savings and reduce operational costs (OPEX).


In this webinar we will address what spectrum analysis should be made and how they can be achieved. We also address how the spectrum analysis will impact the network design. This webinar builds on top of our previous webinars:

  • Webinar 1: How to consider User Traffic in 4G Networks
  • Webinar 2: How to consider Overhead in LTE Dimensioning
  • Webinar 3: How to take into account Customer Experience when Designing a Wireless Network
  • Webinar 4: LTE Measurements, What they mean and how are they used?
  • Webinar 5: What LTE parameters need to be Dimensioned and Optimized

The recorded sessions of our previous webinars are available for viewing on the webinars page.


CelPlan Technologies is pleased to present this free, educational webinar on "Spectrum Analysis for LTE Systems".
