GPRS connection

If the current location is out-of-range, the server will notify the manager via email and trigger the bike’s buzzer. To return, user parks and manually locks the bike anywhere inside the allowed area. Besides, a website is built for administrator’s management. After testing, the electronic lock, mobile, and web application work properly for all functions.

This paper presents a low power Wireless Sensor Network using TCP/IP to use Ethernet configuration and hybrid networks to extend range or improve connectivity in distant areas, in particular is Agriculture. The system is designed with soil moisture sensor based on Atmega8L to monitor environmental parameter. The Nordic nRF24L01 was used to transmit the obtained data to the Web server based on Ethernet configuration. Moreover, the SIM800L module was used to upload these data based on GSM/GPRS service in order to make data available globally.

Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding the data captured on the links and analysing how the different data segments and messages are related to each other. In general I wanted to trace all messages belonging to a single call to prove if the network elements and protocol entities involved worked fine or if there had been failures or if any kind of suspicious events had influenced the normal call proceeding or the call’s quality of service.

The implementation of wireless connectivity is predicated upon the definition of so-called wireless standards, of which GSM, DECT, CDPD, GPRS, and CDMA are examples [7, 8]. Each of these standards embodies the precise set of parameters that dictate the architecture and software design of wireless systems operating under the standard to effect intelligible communicationwith other systems also operating within the standard.
