In the electronics industry a DUT is any electronic assembly under test. [1] [2] For example, cell phones coming off of an assembly line may be given a final test in the same way as the individual chips were earlier tested. Each cell phone under test is, briefly, the DUT. For circuit boards, the DUT is often connected to the test equipment ...
Since cell phones rely on radio waves, which travel through the air and are easily attenuated (particularly at higher frequencies), mobile phones may be unreliable at times. Like other radio transmissions, mobile phone calls can be interrupted by large buildings , terrain, trees, or other objects between the phone and the nearest base.
Mobile-device testing functions to assure the quality of mobile devices, like mobile phones, PDAs, etc.It is conducted on both hardware and software, and from the view of different procedures, the testing comprises R&D testing, factory testing and certificate testing.
This included video streams and a drive test system using TD-LTE. [56] As of 12/10/2010, DirecTV has teamed up with Verizon Wireless for a test of high-speed LTE wireless technology in a few homes in Pennsylvania, designed to deliver an integrated Internet and TV bundle. Verizon Wireless said it launched LTE wireless services (for data, no ...
Test Mobile System (TEMS) is a technology used by telecom operators to measure, analyze and optimize their mobile networks. It is considered as the basic tool to perform wireless network drive testing , benchmarking , monitoring and analysis.
Able to produce a reasonable call with lower signal (cell phone reception) levels. Uses soft handoff, reducing the likelihood of dropped calls. IS-95's variable rate voice coders reduce the rate being transmitted when speaker is not talking, which allows the channel to be packed more efficiently. Has a well-defined path to higher data rates.
RF Drive testing is a method of measuring and assessing the coverage, capacity and Quality of Service (QoS) of a mobile radio network.. The technique consists of using a motor vehicle containing mobile radio network air interface measurement equipment that can detect and record a wide variety of the physical and virtual parameters of mobile cellular service in a given geographical area.
A stress test (sometimes called a torture test) of hardware is a form of deliberately intense and thorough testing used to determine the stability of a given system or entity. It involves testing beyond normal operational capacity , often to a breaking point, in order to observe the results.
