摘要: The smart grid (SG) system is expected to involve huge amount of data with different levels priorities applications or users. traditional which tend deploy propriety networks limited coverage and bandwidth, not sufficient support large scale SG network. Cognitive radio (CR) a promising communication platform for network by utilizing potentially all available spectrum resources, subject interference constraint. In order develop reliable framework CR based network, thorough investigations on the current are required. This paper presents utilization in Malaysia, specifically UHF/VHF bands, cellular (GSM 900, GSM 1800 3G), WiMAX, ISM LTE band. goal determine potential that can be exploit users Measurements was conducted 24 hours quantify average usage bandwidth. findings this important provide insight actual prior developing
