  1. Use Case Possibilities With Bluetooth Low Energy In IoT Applications
    11/2/2017

    Within IoT systems, Bluetooth low energy technology can be connected to the internet to be used as “repeaters” to extend a system’s range. This white paper describes how Bluetooth low energy technology works and how it can be used to connect devices to internet-based services and applications.

  2. 5G Fixed Wireless Radio Validation Case Study
    11/1/2017

    Anritsu recently hosted a major network equipment manufacturer (NEM) at our factory in Morgan Hill, CA USA to perform some early validation of their 28 GHz 5G radios. The application is to use radios for 5G fixed wireless access to compete with fiber to the home. The NEM required the use of the Anritsu Spectrum Master™ MS2720T spectrum analyzer to test the performance of these next-generation 28 GHz 5G radios in a coverage mapping exercise. The spectrum analyzer was used to measure key parameters of the NEM prototype radio in a variety of real-world environments.

  3. Understanding Cable And Antenna Analysis
    10/27/2017

    A problematic base station can be replaced, but a cable and antenna system is not so easy to replace. This article covers fundamentals of cable and antenna analysis measurements: return loss, cable loss, and distance-to-fault (DTF).

  4. 802.11ad Testing With The Spectrum Master MS2760A Ultraportable Spectrum Analyzer
    10/27/2017

    802.11ad is a newer WLAN standard that offers throughput rates up to 7 Gbps. To achieve these speeds, the technology uses newly allocated mmWave ISM bands, specifically 57 to 71 GHz.
