The purpose of an in-building wireless (IBW) system is to provide enhanced network coverage
and/or capacity when the existing macro network is not able to adequately service the
demand. Coverage may be poor due to high penetration losses caused by the building
structure or due to low emissivity glass installed to improve the thermal performance of the building. In dense urban environments, adjacent buildings may create an RF barrier that blocks coverage from nearby macro sites. Tall buildings typically have poor coverage on
upper floors since macro site antennas, many floors below, are specifically designed to
suppress energy radiating above the horizon. Capacity may be an issue in venues such as
stadiums, coliseums and convention centers where many thousands of users may be trying to
simultaneously access the network.
A conversation with Anritsu Company, by Senza Fili in collaboration with RCR Wireless. They discuss how testing evolves as operators densify their networks with DAS, small cells and other solutions. P/N: 11410-00990
Handheld units are designed for the field installation, testing and commissioning of all types of optical fiber systems.
Handheld units are designed for field installation, testing and
commissioning of all types of optical fiber systems.
Hand held units are precision meters designed to meet many testing
applications.The CMA5 Series Fiber Optic Power Meters have calibrated wavelengths at 850, 1300, 1310, 1490, 1550 and 1625 nm. These units can measure absolute power in dBm, and microwatts (μW) along with attenuation (relative power) as dB. The general purpose 5P100 and 5P200 have a range of +10 to -60 dBm, while the 5P100C and 5P200C have a range of +23 to -50 dBm, which is ideal for CATV testing. All models have the ability to store the currently displayed dBm power level reading as a reference for subsequent measurements.
The CMA5 series (Optical Loss Tester/Light Source/Optical Power Meter) measures optical loss and power for optical fiber I&M. The CMA5 series are compact and lightweight, its excellent cost performance and simple operation with the required minimum number of functions make it ideal for onsite I&M. Service engineers can choose from three models - optical loss tester, optical source, and optical power meter - to match the onsite application.
The CMA5 Series Light Sources provide an economical and stable laser source for use in point-to-point attenuation measurement.
The CMA5 Series Power Meters are economnical, accurate and easy-to-use handheld units for attenuation and power throughput measurements on point-to-point fiber optic links.
