The network and radio network laboratory

covers four main aspects of radio-communication based techniques. 

The first one is devoted to different types of radio antenna analysis, such as basic rod and micro-strip antennas. The laboratory equipment consist of educational measurement set which is extended by dedicated software allowing for antenna design and simulation. The software allows to design and evaluate the most important antenna parameters which can be later implemented and evaluated using the measurement unit. A separate software is devoted to horizontal multi-hop radio relay systems design.

The next part of the laboratory is related to satellite communication, investigation of GPS signal reception, proper positioning of satellite dishes, and digital DVB-S, DVB-S2, DVB-T and MPEG-4 streams analysis with respect to modulation schemes. This part of laboratory is also supported by dedicated software capable of both uplink and downlink satellite links design and analysis.

The third part of the laboratory covers wireless local area networking, mainly based on the IEEE 802.11 compliant equipment. Several access points/routers and different wireless interfaces are available to create various types of wireless network topologies, allowing for general network efficiency analysis, analysis of security aspects, analysis of the multi-hop relaying protocols, as well as analysis of the handover support. 

The last but definitely not least part of the laboratory is the modern LTE mobile network. This equipment setup consists of five small base stations (Small cells). Three of them are "Pico cells", intended for use inside buildings - similar in size to Wi-Fi router. The other two are larger devices equipped with transmitters with power up to 5 watts. In addition, the laboratory includes testing LTE smartphones and computers running the operator's network simulator. LTE lab has been equipped by Nokia Solutions and Networks based on cooperation with AGH.

The laboratory is also equipped with 24 PC workstations, 12 routers and 7 Ethernet layer-2 switches.
