“GPRS in modern Telemetry” is an advanced technical training covering all aspects related to telemetric data transmission applications, utilizing GPRS packet transmission in GSM, UMTS and LTE mobile networks. Since GSM technology has the largest geographical coverage and highest reliability, it is presented as a base solution for telemetric applications. Other mobile technologies – UMTS and LTE are described from the point of view of differences in relation to GSM technology, as they are solutions used to ensure high bitrates or minimize delays. The training covers also other services offered by mobile networks that can be used to transfer telemetric date (SMS, USSD, CSD).
The training is dedicated to developers and users of telemetric GPRS systems.
