@openrfid/utils

Math Probability Distributions, Network Helpers, & Bitwise Utilities

🚀 Overview

@openrfid/utils provides shared mathematical algorithms, statistical probability distributions (Gaussian, Uniform, Exponential), RSSI signal loss calculators, bitwise padding, and network address validation helpers for OpenRFID Simulator.

Developed & Maintained by RFID Software India Private Limited.

📦 Installation

# npm
npm install @openrfid/utils

# pnpm
pnpm add @openrfid/utils

💻 Code Example

1. Gaussian RSSI Signal Noise Generator

import { generateGaussianNoise, hexToBinary, binaryToHex } from '@openrfid/utils';

// Generate simulated RSSI noise around mean of -55 dBm (stdDev = 3.5)
const simulatedRssi = generateGaussianNoise({ mean: -55.0, stdDev: 3.5 });
console.log(`Calculated RSSI: ${simulatedRssi.toFixed(2)} dBm`);

// Bitwise Conversions
const binary = hexToBinary('3034');
console.log('Binary:', binary); // "0011000000110100"
const hex = binaryToHex(binary);
console.log('Hex:', hex); // "3034"
