In this article, we will be making an IoT-based pre-paid electricity system and learn exactly how that works. We will create a meter which will monitor the electricity usage and report to a monitoring server (which we will also create) for bills. In an ordinary electricity system, bills come after the usage, and then we…
EDGE Technology : GPRS EDGE Networks
GSM technology was a voice-only service primarily with a few additional features like SMS and low-bit circuit switched data services. Circuit switched services had their disadvantages and hence General Packet Radio Service (GPRS) was introduced in 1999 which allowed data transmission and reception in packet transfer mode within a PLMN without a permanent dedicated route between mobile and the external network.However, it was capable of only 171.2 Kbps theoretically even when all time slots were allocated to data services. For multimedia services, a minimum throughput of at least 384 Kbps is required. As a result, Enhanced Data Rate for GSM Evolution (EDGE) was proposed to European Telecommunications Standards Institute in 1997.
GSM/GPRS Module : All You Need To Know
GSM/GPRS module is used to establish communication between a computer and a GSM-GPRS system. Global System for Mobile communication (GSM) is an architecture used for mobile communication in most of the countries. Global Packet Radio Service (GPRS) is an extension of GSM that enables higher data transmission rate. GSM/GPRS module consists of a GSM/GPRS modem assembled together with power supply circuit and communication interfaces (like RS-232, USB, etc) for computer.GSM/GPRS MODEM is a class of wireless MODEM devices which requires a SIM (Subscriber Identity Module) card just like mobile phones to activate communication with the network and an IMEI (International Mobile Equipment Identity) number for their identification.
