2. 1. Broadband Receiver Electronic Circuits for Fiber-Optical Communication Systems

   Author : Stavros Giannakopoulos; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photodetector; broadband amplifiers; data communication; VCSEL; distributed amplifiers.; receiver front-end; short-haul interconnects; InP DHBT; SiGe HBT; TIA;

   Abstract : The exponential growth of internet traffic drives datacenters to constantly improve their capacity. As the copper based network infrastructure is being replaced by fiber-optical interconnects, new industrial standards for higher datarates are required. READ MORE

4. 2. Massive MIMO for Dependable Communication

   Author : Sara Willhammar; Kommunikationsteknologi; []
   Keywords : 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;

   Abstract : 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). READ MORE

5. 3. Transport Solutions for Future Broadband Access Networks

   Author : Mozhgan Mahloo; Lena Wosinska; Martin Maier; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical access network; mobile backhaul; techno-economic; reliability; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : “Connected society” where everything and everyone are connected at any time and on any location brings new challenges for the network operators. This leads to the need of upgrading the transport networks as the segment of Internet infrastructure connecting the fixed users and mobile base stations to the core/aggregation in order to provide high sustainable bandwidth, as well as supporting a massive number of connected devices.

   Abstract : The consumer of the telecommunication services of tomorrow will expectto receive the same services in a wireless fashion as he today receivesfrom a fixed network. These services require reliable high data rate. READ MORE

7. 5. Broadband Wireless OFDM Systems

   Author : Maxime Flament; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel model; 4th Generation Wireless 4GW ; shadowing; MMIC; WLAN; scenarios; mobile data; OFDM; turbo codes; propagation; license-exempt bands; coding; 60 GHz channel; broadband wireless; interference; Virtual Cellular Network VCN ; front-end;

   Abstract : While the readiness of the telecommunication market and the users' need for broadband mobile data are not currently noticeable, a set of presented megatrends and scenarios suggest that broadband mobile data access will develop quickly in the next ten years. Identification of the potential frequency bands offering cheap and trouble-free wireless infrastructure is therefore an important step towards the definition of new air interfaces. READ MORE
