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...
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...
