Presentation subject : «Using the LTE technology in the construction of wireless communication»

Relevance Suffice it to rapid development of the Internet makes ever greater demands for data transfer speed in terms of mobility. mobile communication technology of the 3rd and the younger generations do not always have sufficient speed for streaming video in high definition, the use of cloud services and other demanding tasks speed. To satisfy these requirements enable mobile network based on the LTE technology. To ensure good quality of provided access to the Internet, you must take into account the losses resulting from the propagation of signals. Research carried out in this paper will help to choose the optimal parameters in the construction of wireless networks based on LTE technology.

Generation of wireless networks

In telecommunication , Long-Term Evolution ( LTE ) is a standard for high-speed wireless communication for mobile phones and data terminals, based on the GSM / EDGE and UMTS / HSPA technologies. In telecommunication , Long-Term Evolution ( LTE ) is a standard for high-speed wireless communication for mobile phones and data terminals, based on the GSM / EDGE and UMTS / HSPA technologies. LTE provides a theoretical peak data rate of up to 326.4 Mbit / s from the base station to the user and to 172.8 Mbit / s in the opposite direction.

LTE network structure

Calculation part. Initial data Calculation of the main parameters of the radio access using LTE technology in some areas in urban areas. Area- 100 km2 Population- 250 thousand people Used frequency band– Band 7(2600MHz). Used frequency duplex FDD Downlink: 2500—2570 MHz (using 10 MHz 2500 – 2510) Uplink: 2620—2690 МГц (using 10 MHz 2620 - 2630) The average height of the base stations suspension - 50 m. The average height of the mobile station - 1.5 m.

Choice of equipment

Calculation of the receiver's sensitivity

Calculation of the energy budget for the LTE network

Calculation of the coverage area

In the following graphs depict the dependence of the loss of the radio frequency. BS antenna suspension height is taken to be 50 m. Distance from the MS - 1077 m.
