Did you know that cellular companies hire climbing specialists to scale radio towers to work with techs to do RF interference testing? Eduardo Inzunza, business development wireless business unit at JDSU (News - Alert), says they do.
The climber fees are typically at least a couple thousand dollars, he says, but the cost of hiring them and getting them out to the tower is an even greater cost.
In response to this obviously very inefficient process, JDSU has expanded its CellAdvisor Base Station Analyzer with Radio Frequency over Common Public Radio Interface capabilities. As a result, technicians will be able to plug in the CellAdvisor into an optical coupler on the link and take a signal samples from the ground. This new feature is available with a new card, which becomes generally available next month.
Operational systems from some of the big cellular infrastructure suppliers allow network operators to log in to get a snapshot of interference and signals on the system, says Inzunza. But, he says, that information is not delivered in real time, and it’s presented in 150khz blocks, so it’s not ideal for interference hunting. To do it right, he says, cellular network operators need a real-time spectrum analyzer with better resolution like the one JDSU supplies.
JDSU introduced the CellAdvisor a few years ago. The solution was first introduced to test all points on convention cell sites. It then evolved to address cell sites with distributed designs, adding a fiber scope to test fiber connectors and test optical power. And now it addresses the tower climbing issue.
In other news out of JDSU today, the company announced that it plans to separate into two publicly traded companies in an effort it says will allow it greater flexibility in addressing the rapidly changing telecom and cloud network markets. One of the companies will focus on optical components and commercial lasers; the other will address network and service enablement, including the move to software-defined networks. The split is expected to be completed in the third quarter of next year.
