Gdansk University of Technology
The Laboratory of Mobile Wireless Technologies at Gdansk University of Technology (GUT) provides an ability to conduct experiments in a real environment of a modern mobile user. A dedicated infrastructure of a managed distribution and access network spans diverse metropolitan areas, including:
- university campus,
- sparse and dense housing areas,
- commercial areas,
- local and main city streets,
- metropolitan railway line,
- maritime port facilities and some areas of the Bay of Gdańsk,
- tourism-oriented areas.
With both Local Area Network (such as IEEE 802.11 a/b/g/n/ac) and Metropolitan Area Network (RADWIN Fiber-In-Motion and Jet) technologies present in its infrastructure and client nodes additionally equipped with Wide Area Network interfaces (LTE), the Laboratory allows a comprehensive experimentation scenarios to be performed.
The abovementioned ability to perform a real-world testing of a diverse range of solutions, starting with new transmission mechanisms, through middleware implementations and ending with various applications intended for mobile users, makes it possible to verify their functionality and performance in their intended deployment environment. An additional remote radio spectrum analysis included in the infrastructure devices, allows for results to be interpreted with ease.
Examples of possible research topics include:
- network integration in 4G and 5G networks,
- self-organizing, multihop wireless structures,
- wireless network virtualization,
- mobility and handover management in both homogenous and heterogenous systems,
- delay tolerant networking,
- wireless network security,
- cooperation and coexistence of new wireless transmission technologies,
- various application level mechanisms verification and performance testing.
The Laboratory of Mobile Wireless Technologies at GUT provides an infrastructure of about 15 installation points located in the Tri-City metropolitan area, each equipped with:
- an IEEE 802.11 a/b/g/n/ac compatible wireless access point, featuring two independent 2.4/5 GHz MIMO 3×3 network interfaces, which can be employed for both network access and remote physical layer spectrum monitoring,
- a multi-purpose router equipped with an IEEE 802.11 a/n/ac compatible wireless interface operating in 5 GHz band, capable of MPLS support complete with traffic management and VPLS functionality.
The dual-interface access points operate under control of a Fortinet centralized wireless network controller, supplemented by a dedicated Network, Spectrum, Service and Security Management system.
The above WLAN infrastructure is supplemented by two RADWIN Metropolitan Area Network base stations utilizing proprietary RADWIN Fiber-In-Motion and RADWIN Jet technologies.
Apart from the access infrastructure, the Laboratory allows the use of the following types of mobile nodes which can be used to conduct experiments in the described access infrastructure:
- 10 mobile nodes – ECN-680AW-H61 industrial computers (Intel i5 processor, 2 GB memory, TPM module, SSD drive), equipped with IEEE 802.11 b/g/n MIMO 2×2 WLAN and programmable Bluetooth interfaces.
- 10 high capacity mobile nodes – Advantech UNO-3083G industrial computers (Intel i7 processor, 16 GB memory, SSD drives), equipped with GPS receivers, IEEE 802.11 a/b/g/n/ac MIMO 3×3, LTE (2×2 MIMO) and Bluetooth wireless interfaces.
- 10 nomadic terminals – portable, extendable micro-ATX computers (Intel i5, 8GB memory, SSD drive),
- 2 RADWIN Fiber-In-Motion and 2 RADWIN Jet client terminals.
