WIRELESS LAN FOR IOT 5G APPLICATIONS IN A CONGESTED INDOOR ENVIRONMENT: IMPROVED PRIMARY SIGNAL SENSING AT MILLIMETER-WAVE V-BAND [40 – 75 GHZ]

Abstract. Presently, the IEEE 802.11ad wireless network standard supports the communication capability within the V band of millimeter-Waves (or mm-Waves) [40 – 75 GHz] for Internet of Things (or IoT) technology. This paper presents an algorithm to improve the Primary Signal 5G (or PS_5G) sensing at 60 GHz in WLAN_IoT-5G (or Wireless Local Area Network for IoT-5G). To achieve that, we aim at investigating and assessing the sensing performances of the PS_5G from the Access Point of WLAN_IoT-5G (or APWLAN_IoT-5G) by the Secondary User IoT-5G (or SU_IoT-5G) in a congested environment using a simple energy detector (or SED) algorithm and a simple recursive estimator (or SRE). In addition, the SU_IoT-5G is regarded as a mobile user in WLAN_IoT-5G by employing the Gauss-Markov Random Mobility Model (or GMRMM). Through various scenario simulations, the performances and the robustness of the proposed algorithm are proved.
