![]() It includes PHY, MAC and upper layers.įor PHY layer analysis, various test and measurement applications are developed which will work with or without RF hardware.įor MAC and upper layer protocol analysis MAC sniffer and protocol analyzers compliant to wimax standard have been developed. WiMAX subsystems(SS and BS) will composed of multiple layers in a protocol stack. RF spectrum analyzer will help analyze RF issues if any. Wimax network analysis requires over the air protocol analyzer. Will use the same frequency at different time instants. The system works mainly based on TDD frame concepts where in downlink transmission of base station and uplink transmission of subscriber station This system composed of two subsystems viz. WiMAX system is mainly designed as replacement of existing wired line internet technologies such as ADSL. To measure absolute power level power meter will be very useful. Other equipments needed for frequency stability testing is frequency counter. There is a way to verify receiver part by checking received RF signal strength in modem or in spectrum analyzer.Īnother important parameter is Eb/No or CNR to be checked in the modem.īased on BER and modulation type, different CNR(or Eb/No) is required for the VSAT system to work efficiently. If the RF signal is not visible in the spectrum analyzer then the VSAT is either off or have got some problem in RF part This helps to know if any VSAT station is powered on and transmitting the carrier or not. The VSAT network engineer need to have spectrum analyzer to monitor the RF frequenciesĪllocated to different VSATs and Hub station. VSAT network analysis requires knowledge of RF part after installation. There are various RF bands of operation in VSAT viz. Mesh system consists of VSATs with larger antenna. Star system consists of VSATs and a hub station. Indoor part composed of mux-demux, modem and small exchange (PBX). The outdoor part composed of antenna and RF subsystems(RF ODU, PA, LNA). VSAT system usually will have two parts viz. ![]() VSAT stands for Very Small Aperture Terminal. These remote areas are not feasible to lay copper cables and fiber optic cables. VSAT is used as transmission system for providing voice and data connectivity to remote areas. This generic guide of wireless network analysis will help find solutions to the problems or issues related to these wireless technologies. It covers tools used for troubleshooting by developers and network engineers across the world. This page describes wireless network analysis basics which can be applied to any network as per vsat,wlan,wimax,gsm,cdma and Wireless network analysis-vsat,wlan,wimax,gsm,cdma,lte
