Kumbesan Sandrasegaran and 2. Solaiman Ahmed 1. Faculty of Engineering and Information Technology, University of Technology, Sydney, Australia 2. Department of Electrical and Electronic Engineering, University of Dhaka, Bangladesh A BSTRACT The four basic Radio Resource Management (RRM) measurements in Long Term Evolution (LTE) system are Channel Quality Indicator (CQI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Carrier Received Signal Strength Indicator (RSSI). A measurement of channel quality represented by Signal to Interference plus Noise Ratio (SINR) is used for link adaptation along with packet scheduling, whereas RSRP and RSRQ are needed for making handover decision during intra- e. UTRAN (evolved Universal Terrestrial Random Access Network) handover in LTE. In this paper, some practical measurement results recorded from a live LTE network of Australia using a commercial measurement tool namely NEMO Handy are analysed to verify the possible relationships among SINR, RSRP, RSSI and RSRQ as well as to evaluate the effects of SNR on throughput. In addition, the intra- e. UTRAN handover events occurred during the test period within the test area are studied. What are the units of RSSI, noise and SNR as defined by IEEE 802.11? Let's say measurer is my Macbook Air running builtin Wireless Diagnostic tool. I'm actually not sure where the noise measurement is coming from offhand. Received Signal Strength Indication Contents. This document discusses the measurement of received RF signals and how these. While RSSI can be used as a tool to give an indication of link quality. Screenshot of the RSSI measurement of wireless networks by inSSIDer. Top 3 choices of wireless transmitters. The analysis yields some useful information such as: if the SINR is good for a measurement slot, higher throughput is achieved; RSRP and SNR are proportional to each other on average; and lesser is the difference between RSSI and RSRP, better is the RSRQ – each of which is consistent with theory. All the measurement results are evaluated using computer programs built on MATLAB platform. LTE, commonly marketed as 4. G, is the 3. GPP- standardized OFDMA/SC- FDMA (Orthogonal Frequency Division Multiple Access in downlink/ Single Carrier Frequency Division Multiple Access in uplink) based wireless cellular system, which mainly focuses on providing high peak data rates, high spectral efficiency, improved capacity and coverage, short round trip time, and spectrum flexibility . LTE radio access network, usually termed as e- UTRAN, consists of e. Node. Bs only where all RRM- related functions are performed. RRM ensures that the air interface resources are efficiently utilized so that network efficiency is maximised, Quality of Service (Qo. S) required for each service/bearer/user be guaranteed, and high capacity and planned coverage are maintained. The RRM functionalities comprise of a range of algorithms employed for the optimal utilisation of radio resources. LTE RRM functions can be categorized as network based functions and connection based functions .
