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.
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.
4G networks provide even higher bitrates and many architectural improvements, which are not necessarily visible to the consumer. The current 4G systems that are deployed widely are WIMAX and LTE. The two are pure packet based networks without traditional voice circuit capabilities. These networks provide voice services via VoIP or VoLTE.
LTE (Long Term Evolution) is commonly marketed as 4G LTE, but it did not initially meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. Given the competitive pressures of WiMAX and its evolution with Advanced new releases, it has become synonymous with 4G. It was first ...
Cellular V2X uses 3GPP standardised 4G LTE or 5G mobile cellular connectivity to exchange messages between vehicles, pedestrians, and wayside traffic control devices such as traffic signals. It commonly uses the 5.9 GHz frequency band, which is the officially designated intelligent transportation system (ITS) frequency in most countries.
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 ...
This equipment is used to extend the coverage of a baseband unit in challenging environments such as rural areas or tunnels. RRHs are generally connected to the baseband unit or base station which can be an x86 server [ 2 ] on the ground near a cell tower, via a fiber optic cable using Common Public Radio Interface protocols.
The Qualcomm Snapdragon modems are a series of 4G LTE, LTE Advanced, LTE Advanced Pro, and 5G NR modems found in many phones, tablets, laptops, watches and even cars.
