# Power Consumption and Energy-Efficiency for In-Band Full-Duplex Wireless Systems

## TL;DR

This paper develops an analytical model to compare power consumption and energy efficiency between In-Band Full-Duplex and Half-Duplex WLANs, showing IBFD's higher power use but better energy efficiency.

## Contribution

It introduces a new analytical model for IBFD WLAN power consumption and compares its energy efficiency with HD WLANs, validated by simulation results.

## Key findings

- IBFD systems consume more power than HD systems.
- IBFD WLANs have higher energy efficiency despite increased power use.
- The analytical model closely matches simulation outcomes.

## Abstract

This paper presents an analytical model of power consumption for In-Band Full-Duplex (IBFD) Wireless Local-Area Networks (WLANs). Energy-efficiency is compared for both Half-Duplex (HD) and IBFD networks. The presented analytical model closely matches the results generated by simulation. For a given traffic scenario, IBFD systems exhibit higher power consumption, however at improved energy efficiency when compared to equivalent HD WLANs.
