GSM VS. CDMA Why You Should Know The Difference CDMA or GSM refers to the type of network technology the phone uses. Some carriers use CDMA and some use GSM. Your choice of carrier and the technology it uses for its network might make the difference between being productive and connected or ending up with no signal. It’s probably the understatement of the decade to say that cell phones have become the single greatest tool in business. In today’s world the ability to communicate with business

PREPAID ENERGY METER The present system of energy billing is error prone and also time and labor consuming. Errors get introduced at every stage of energy billing like errors with electro-mechanical meters‚ human errors while noting down the meter reading‚ and errors while processing the paid bills and the due bills. There are many cases where the bill is paid and then is shown as a due amount in the next bill. There is no proper way to know the consumer’s maximum demand‚ usage details‚ losses

SMART ENERGY METER A smart meter is usually an electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors‚ smart meters can gather data for remote reporting. Smart Meters" usually involve real-time or near real-time sensors‚ power outage notification

proper‚ Torque was discussed extensively. The experiment is divided into two parts. In the first experiment‚ the meter stick was weighed and the group was tasked to find the center of gravity of the uneven meter stick and supporting the meter stick other than its center of gravity‚ bring it into equilibrium using the weight of a single mass. In the second part of the experiment‚ the meter stick was supported on the 30 cm mark and weights were applied (200g at 10 cm mark‚ 100g at 20cm mark‚ 20g at
