The telecommunications sector accounts for roughly 4 percent of the global electricity consumption. However, the sector is actively participating in efforts to reduce energy use – both for economic reasons, such as reducing operating expenses, and for environmental reasons.
As part of a new upgrade for a basketball arena in a large state university, the wireless network was to be improved to provide spectators with more venue coverage and capacity, particularly for high-bandwidth services. In order to meet this challenge, test tools were needed that could simplify the complexity of collecting thousands of traces to verify DAS installations as quickly as possible. The Anritsu Site Master™ handheld cable and antenna analyzers, PIM Master™ portable passive intermodulation analyzer, and the award-winning SkyBridge Tools™ Test Manager were used to reduce project testing time by 70 percent.
A few years ago, driving while using a phone was practically unheard of or frowned upon. Today, it’s actually quite the opposite. From GPS navigation to infotainment, voice-controlled texting to cloud data transfer, the use of cell phones and other mobile devices is so prevalent while driving that many car manufacturers now offer WiFi in the vehicle. Nevertheless, the additional cell phone usage and significant amount of send/receive data increases the chance of a dead battery alongside the panic of finding a charging cord and plugging it in. The solution? Inductive charging. This white paper describes the technology behind wireless charging, its challenges, and Laird’s latest solutions for automotive wireless charging modules. .
As LTE technology evolves and grows, concerns are also rising about the impact it will have on the Land Mobile Radio (LMR) industry. Even with the surplus amount of information on this subject, many questions remain unanswered. It is known that every segment of the LMR industry will be affected in one way or another, but exactly how much LTE will affect an organization or individual will depend on what roles they implement. This white paper discusses the LTE/LMR topic with facts and examples so that readers may determine what impact LTE will have on them.
Global Navigation Satellite System (GNSS) based solutions are highly accurate in most cases, but there are circumstances where they are not as effective, such as in dense urban environments with reduced satellite visibility or indoor areas with low signal levels. LTE Location Based Services (LBS) are designed to determine where a device is located to assist in its effectiveness. This Rohde & Schwarz white paper describes limitations of GNSS systems, as well as LTE cellular based alternatives within 3GPP Release 9.
