Passive Intermodulation (PIM): DAS & Signal Booster RF Interference
Dec 28, 2017
Interference becomes a real challenge when 2G and 3G wireless network infrastructures are overlaid with 4G LTE networks. Although PIM has always been an issue for RF communications involving more than one frequency, LTE is more sensitive to these effects. Cell phone signal booster systems and passive or active distributd antenna systems (DAS) are particularly vulnerable to this interference while they try to amplify available weak signals. PIM is the interference that results from mixing frequencies in a passive circuit in a nonlinear fashion. Network throughput and performance can be crippled if the interference is the same as the network’s...
More Efficient, Lower Cost DAS w/ CPRI (Common Public Radio Interface)
Dec 28, 2017
DAS solutions fed by CPRI have been proven to improve performance and reduce overall cost when compared to DAS architectures that are based on traditional RF. What is CPRI? CPRI stands for Common Public Radio Interface. It is a wireless communications network specification that is still evolving. It is defined by a group of OEMs and addresses the communication link between the radio equipment, known as remote radio units (RRUs) and radio equipment controller units, commonly called baseband units (BBUs). CPRI is however not a standard, as it only defines the critical conditions for connectivity, control communications and interfacing transport...
What are Low-PIM Antennas, Cables, and Connectors?
Dec 26, 2017
To understand what low-PIM antennas, cable and connectors mean, it is vital to understand what PIM refers to. PIM stands for Passive Intermodulation. It is a problem that happens largely in passive devices such as antennas, cables and connectors where interfering signals are generated by nonlinearities within a wireless system's mechanism. Amplitude modulation or the mixing of two signals occurs, producing difference in signals within a specific band leaving behind significant interloping. Nonlinearities effect. Passive intermodulation product is also explained as resulting from the mixing of two high power natures at the nonlinearities of devices, such as in corroded connectors,...
How to Boost Cell Phone Signal Strength in Home & Building?
Dec 05, 2017
No phone reception at work? What to do about poor cell signal? How to improve cell phone signal strength in home & building most effectively, and easily? Terrible cell service at certain times? The most foolproof and easiest way to get stronger cell phone signal strength inside homes and cement buildings is to install a cell phone signal booster for homes and buildings. These cell phone coverage extenders are highly effective devices based on a legitimate technology. They are certified by FCC and pre-approved by all cellular service providers in USA & Canada pending registration after purchase. They work by...
Best Rural or Remote Area Car & RV Cell Phone Signal Boosters
Nov 13, 2017
Which one is best for my car, truck, and RV? Driving to remote areas? How to make cell phone work in remote areas? How to get cell coverage in remote areas? Install the most powerful cell phone signal booster in your car, truck, or RV before you go! The reason why a vehicle 3G + 4G + LTE signal booster is an essential automotive accessory is because the cellular reception may be spotty at best in many areas on such long isolated stretches of freeways, highways, and rural roads. When comparing best rural or remote area car and RV cell phone...
