Title: Innovations by Johannes P. Haagh

Introduction

Johannes P. Haagh is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of wireless communication, holding a total of 4 patents. His work focuses on enhancing the efficiency and reliability of communication systems.

Latest Patents

One of his latest patents is a power control method in a wireless communication system. This innovation involves a wireless local area network that utilizes dynamic transmit power level control. The system ensures that only the power level necessary for reliable transmission to a specific station is used. Each transmitted information packet contains a byte representing the power level at which it was sent. The power level at which the packet is received is measured, and a path attenuation value is calculated. This value is averaged over multiple packets and used, along with a measured interference level, to determine an appropriate transmit power level for that path. Additionally, an associated defer threshold level is established, and both the transmit power levels and defer threshold levels are stored in a table.

Another significant patent by Haagh is a method of transmitting selected message frames without individual identification. This local area network system includes a host computer connected to a wired LAN with several bridges. These bridges connect to respective wireless LANs operating on a common wireless communication channel. When a new terminal is added, the bridges identify download message frames from the host computer and retransmit each frame over the wireless channel in non-overlapping time intervals with different delays. Each download message frame is transmitted twice by each bridge, ensuring efficient communication.
