Vendors are working to make network equipment more flexible, power efficient and smaller to suit the needs of operators. Many of the newest offerings also are intended for use in improving wireless coverage in large, high-capacity venues such as stadiums, where the need for...

Neutral host Distributed Antenna Systems (DAS) operate over a wide frequency range in order to accommodate as many users as possible. The antennas and RF power distribution network are typically designed to pass signals between 698 to 2700 MHz, and sometimes wider. A question...

PIM testing has become more critical as telcos move to 4G LTE networks.

PIM testing enables carriers to reduce harmful network interference.

How Passive Intermodulation Affects Network Performance Passive intermodulation (PIM) is a big concern for wireless providers because of the negative effect it can have on network performance. In active devices, PIM occurs when signals at two or more frequencies mix with each other in a non-linear...

Until recently, PIM (Passive Intermodulation Distortion was only a concern for wireless networks, and ultimately, the wireless user. Today, cable manufacturers are involved as certain low PIM cables are necessary for maintaining and testing this annoyance and potential service inhibitor. And even though PIM is not a...

If you're well-versed in today's wireless industry, you know Passive Intermodulation (PIM) is a big part of keeping wireless networks up and running, with the ability to meet the high data demands of today's wireless users. PIM testing, however is not cheap making the...

Passive Intermodulation (PIM) testing is no stranger to the wireless industry. In fact, it is a standard for radio site commissioning and certification. PIM's history dates back to the beginning days of radio communication and has become a major performance issue for wireless carriers...

Passive Intermodulation (PIM) is becoming more and more important as wireless users demand data, with high speeds. It affects network speed and performance, therefore, needs to be monitored, making PIM testing a basic requirement especially today. What is PIM? PIM occurs when two or more high...

Antenna Evolution - Meeting the Demand for LTE, Small Cell, & DAS Networks Implementations of Small Cell and DAS systems have many challenges; not the least of which is the selection and placement of the antenna elements.  Since these systems deploy antennas close to the users,...

Systems integrators who specialize in DAS deployments are working overtime to meet demand, and scrambling to find enough qualified RF engineers. "I have guys working 24 hours a day seven days a week. Obviously not one team, but it is not uncommon anymore for...

Westell Technologies Inc. has acquired Cellular Specialties Inc. for $39 million. CSI develops in-building wireless systems including distributed antenna systems (DAS) and small cell connectivity. Rick Gilbert, chairman and CEO of Westell, called CSI a "great complement" to Westell's portfolio for site solutions and "an...

The test and measurement industry is putting out the welcome mat for the industry to venture into LTE-Advanced, as was evident in much of the news out of Mobile World Congress this week. Not only do the vendors want to establish themselves at the...

In-building wireless solutions continue to attract significant investment from operators and neutral host providers, with the $4.4 billion market projected to almost double by 2019. Alcatel-Lucent and TE Connectivity have joined forces in an effort to help operators cut costs on distributed antenna system...

Low Profile, 8.19" PIM Certified iDAS Antenna Commercially Available for Cost Effective In-Building Small Cell LTE Applications TORONTO, ON--(Jan 28,...

JDSU's CellAdvisor JD780A Base Station Analyzer series now supports LTE-Advanced with the ability to analyze up to five component carriers for carrier aggregation, and MIMO with up to four transmitting branches. JDSU has also added basic PIM detection, so that a tech can tell whether interference is...

Welcome to our weekly collection of all the top cell tower news stories, where we cover global, national, regional, local and distributed antenna system stories. While hoopla surrounding the "polar vortex" may have subsided, we're still in the dead of winter in many parts...

Ixia announced that Vic Alston resigned as its president and CEO after a company audit committee found that he had lied about his credentials. Alston had attended Stanford University as he claimed, but falsely stated that he had received a B.S. and M.S. in...

Anritsu Webinar: Distance-to-PIM™ (DTP) is an important feature to help identify the location of Passive Intermodulation (PIM) faults both inside the feed system as well as beyond the antenna.  When used correctly, this feature will help technicians quickly and efficiently locate PIM sources at a...

Agilent Technologies has added new functionality and options to its M9703A AXIe eight-channel wideband digital receiver/digitizer (pictured at right), which is used for measurements in communications and the aerospace/defense industry. The equipment is designed for wide analysis bandwidth on up to 40 phase-coherent channels,...
