This project provides five online calculators designed to compute various wireless network parameters. The calculators allow users to input system parameters and obtain important values related to:
- Bit rate calculations for sampler, quantizer, source encoder, channel encoder, and interleaver.
- OFDM resource element calculations for bits per symbol, resource block, and transmission rate.
- Power transmission estimation based on transmitter and receiver specifications.
- Throughput computation for different Carrier Sense Multiple Access (CSMA) protocols.
- Cellular system design for estimating cell size, number of cells, and total traffic.
