Using Wallys Communications DR4018H access point

Introduction

WiFi Analyzer is an open-source app for Android, available for download from Google Play.
It allows the user to optimize their WiFi network by examining surrounding WiFi networks, measuring their signal strength as well as identifying crowded channels.


This application does not require access to internet, therefore it does not send any personal/device information to any other source and it does not receive any information from other sources.
I installed it on my Samsung Galaxy smartphone and I tested the connection to the Wallys Communications DR4018H access point (see picture below) . The findings are described below.

Procedure

I linked the AP to my home router in the entrance hall of my apartment.

The SSID is called “WIFIA” and the smartphone is connected. It receives a local IP address from the router directly connected to the AP.
 
 
The received power at about 1m distance from the AP is -37dBm on channel 5 at the frequency of 2.432 MHz with a channel width of 40MHz. The bandwidth in download is 72 Mbps.

Other than the list of APs in the area, the app displays the channel rating and the signal strength. Channel 5 is among the best and 2 APs are active on that channel.



 
 
I moved away from the AP by walking slowly from my house along the straight access road, which is about 70m long: these data changed along the way.
This are the time graphs at 14m and 31m distance: the signal strength is -63dBm and -70dBm respectively.

This can be summarized in the following graph.

However, I noticed that the distance is slightly overestimated. When I was about 60m away from my house, the software was showing 80m distance. Anyway, even at that distance, I could watch a video on Youtube without interruptions and I also made a WhatsApp call: the voice was clear and the line was steady.

Conclusion

The DR4018H access point from Wallys Communications provides excellent coverage and signal strength for browsing the internet, using social media and making phone calls with WhatsApp.

Linux CentOS 7 - Mounting the iso file as a CD-ROM

Linux CentOS 7 - Mounting the iso file as a CD-ROM in a repo Mount the iso file as a CD-ROM in a repository. Provided your iso file contains the complete operative system, this allows you to disable the default repositories and mirrors and install all required packages without downloading them from the internet. In other words you can work off-line. On system1 and/or system2 Edit the repo file vim /etc/yum.repos.d/CentOS-CD.repo [CentOS-CD] name =  CD ROM baseurl = file:///media/CentOS gpgcheck = 0 enabled = 1 Mount the iso file as a CD-ROM in a repository. Make a mount point mkdir /media/CentOS Edit the fstab file /dev/cdrom     /media/CentOS   iso9660   loop 0 0 mont -a Verify df -Th it must return the /dev/loop0 disk yum repolist it must show the repositories contained in the iso file.
