Design of the wireless sensor and communication network
Ptáček, Zdeněk ; Šteffan, Pavel (referee) ; Pavlík, Michal (advisor)
The thesis deals with the study of the existing wireless network types, propose and realisation of a dedicated wireless network based on using nRF24L01+ wireless module. The aim is to design a simple, reliable and multifunctional low-cost wireless network. The cellular tree topology and random retransmission delay are used to eliminate cross-talks. Low propagation time is achieved by using ALOHA Access Protocol. Network units cooperate with peripherals in order to measure temperature, humidity, illumination level and other. The power down mode is used to increase duration of battery powered network unit. Practical part of the thesis is focused on creating a computer program to control and set up the network. The network provides a central or autonomous mode.

Design And Realisation Of The Wireless Communication Network
Ptáček, Zdeněk
This work deals with usage of wireless communication circuit nRF24L01 + for the realization of a dedicated wireless network using tree topology. Each wireless unit controls its own base frequency band. The wireless network uses some basic peripherals for temperature, humidity and ambient light measurements.

Central Unit of the Wireless Sensors Network
Ptáček, Z.
This article deals with function and control description of wireless communication circuit nRF24L01+ and its possible use for the creation of local wireless sensor network of tree topology. Further is described function of sensor network and designes the central control unit for measured data collecting. Collected data are sent to computer and displayed to user. Finally there is considered possibility of powering modules by battery.
