Impact of Mobile phone in the Air and Random Access Channel RACH with Time Division Multiple Access TDMA Noise in Aircraft Avionics

TL;DR

This paper investigates the impact of mobile phone signals, especially the high-power RACH in TDMA systems, on aircraft avionics noise, highlighting the need to understand RACH's effects during calls.

Contribution

It uniquely analyzes the influence of RACH and TDMA noise in aircraft environments, an area less explored compared to low-power mobile emissions.

Findings

RACH can emit up to 30dBm during call initiation

TDMA noise significantly affects aircraft avionics

Mobile phone signals impact aircraft communication systems

Abstract

Mobile phone 1800MHz band already allowed to be used in some airlines. Many studies talked about lower the mobile phone output power to the lowest of 0dBm, but seldom talk about the Random Access Channel RACH, which will emit at the highest power of 30dBm at the instant of call making and is not controllable until the connection between the Base Station and mobile is made.Hence the impact of RACH and TDMA noise generated in the aircraft.
