Voice Over LTE (VoLTE) Speech Quality Measurements
This Rohde & Schwarz application note and associated application software may be used to conduct psychoacoustic speech quality evaluation for Voice over LTE (VoLTE) connections. The measurements are based on recommendations ITU-T P.862 and ITU-T P.863, respectively. The R&S CMWrun Software Sequencer Tool example sequences perform decoder / encoder calibration, connection setup for the UE under test and subsequent speech quality analysis under IP impairment conditions.
Wireless Dose-Compliance Monitoring In Drug-Delivery Devices
Incorporating wireless technology into medical devices is about more than just keeping up with the hottest technology trends; the benefits are real and significant, especially with regard to monitoring and encouraging dose compliance in the pharmaceutical and medical realm. Prior to embarking on the development of a wireless-enabled drug-delivery device, however, it is crucial to know what, specifically, the benefits are, and exactly what kinds of challenges and design considerations must be taken into account.
Is Wi-Fi More Dangerous Than We Think?
A little known fact about the electronic devices we use is that the radio frequency electromagnetic fields they generate are classified as Class 2B Carcinogens by the World Health Organization. New analysis by researchers contends that children are particularly susceptible to this type of radiation.
Google Lobbies For 3.5 GHz Band To Provide Cheaper Wireless
With the intent of making alternative wireless services available, Google is lobbying the Federal Communications Commission (FCC) to open up the mostly vacant 3.5 GHz spectrum. Vast amounts of low-cost bandwidth could be available at a price that would undercut services from larger carriers. As prices for access to traditional wireless spectrums continue to soar, this alternative could be a boon for consumers.
The Advantages Of Millimeter Wave Transmission Systems Over Fiber Optics
Traditionally, wireless communication has been limited in its capacity to transport gigabit quantities of data due to bandwidth limitations set by the FCC, making fiber-optics a relevant alternative for communication systems. That all changed, however, with the opening of the 71 to 76 and the 81 the 86 GHz bands — referred to as the “E-Band” range of millimeter wave (MMW) frequencies. This article discusses the advantages that MMW communication systems have over their fiber-optic counterparts.
