...can send/receive calls through SIP (Can use any sip stack like sipdroid) and forward it to the GSM network. If android Layers have a problem for this job, you can use replicans OS. The application should then forward the audio and convert from SIP to GSM and vice versa. Full description below. Please review and message me with considerations. If
...one of the question. The 3GPP AKA is an improvement of the GSM (i.e., 2G) AKA scheme by allowing mutual authentication between the MS and the VLR. The counter-based VLR authentication mechanism in 3GPP may encounter a desynchronisation problem. Design a new approach to improve the GSM AKA scheme for mutual authentication without bringing any synchronisation

Gsm Gps Based Bus tracking System (8051+Arduino) Bus station (8051 + Gsm) - to display Gps content On bus (Arduino + gps + gsm) - collect data from gps send the data via sms to bus station
Target is to make a simple single layer PCB of approx. 300x300mm that contains several SMD LED´s. The only parts are LED Chips and the series resistors and a THT header. PCB Design should be done in eagle or Altium (eagle preferred)
my project is about creating a dashboard that contains 25 storage tanks that I want to track levels in these tanks in a daily, weekly monthly and yearly basis. the weekly, monthly and yearly levels will be based on average levels calculation. the data of tank names and numbers and max levels will be provided by me the only data I have to plug in manualy is the current levels. I want excel to gener...
