    Sammanfattning : In the ever-evolving landscape of wireless communication, the deployment of millimeter-wave (mmWave) technology has emerged as a game-changer for indoor environments. As the demand for high-speed, low-latency connectivity continues to surge, especially in densely populated areas, mmWave access point deployment has gained prominence due to its ability to deliver unprecedented data rates thanks to the available wide bandwidths.

  3. 2. Radio resource management for wireless indoor communication systems : performance and implementation aspects

    Författare :Stefan Pettersson; KTH; []
    Nyckelord :Radio resource management; indoor communication; the bunch concept; centralized RRM; dynamic channel allocation; channel selection;

    Sammanfattning : In this thesis, we investigate several radio resourcemanagement (RRM) techniques and concepts in an indoorenvironment with a dense infrastructure. Future wireless indoorcommunication networks will very likely be implemented atplaces where the user concentration is very high. At these hotspots, the radio resources must be used efficiently.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel characterisation; Channel measurements; Channel modeling; Industrial automation; Industry 4.0; Internet-of-Things; Massive MIMO; mMTC; Reliability; URLLC;

    Sammanfattning : Cellular communication is constantly evolving; currently 5G systems are being deployed and research towards 6G is ongoing. Three use cases have been discussed as enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC). LÄS MER

  5. 4. High Capacity Fiber-Connected Wireless MIMO Communication

    Författare :Husileng Bao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; central unit; Radio-over-Fiber; millimeter-wave.; multiple-inputmultiple- output; remote radio head;

    Sammanfattning : There will be more and more users while beyond-5G (B5G) and 6G bring more wireless applications. Current cellular communication networks assign specific serving boundaries for each radio, which becomes a limitation when too many users work with one radio simultaneously. By physically distributing radios. user’s service can be more uniform. LÄS MER
