Poor Mobile Connection and Cell Phone Signal Booster

You’re finally moving out of the city. A house of your dream in the peaceful countryside far from noise, crazy traffic, smog, and signal reception…Could you assume it would be like this?Mobile connection in rural areas is often unreliable. You can pick up instead a strong signal outside your house, but it’s not possible to get it inside. The countryside is not the only area where you can lack coverage. Even in the offices in the very heart of a busy city, it’s often hard to make calls and access speedy 3G. Why does it happen today when mobile network service is at such a high level?! Why can the mobile signals be poor? You can have an excellent signal at home, but in the garage, office, café or shop located underground, you can face signal problems again. It’s so because it’s hard for signals to penetrate the ground.

Expanding Raspberry Pi 3 WiFI range with external antenna

The Raspberry Pi 3 Model B uses standard 2.4GHz 802.11n wireless technology, which typically has a range of up to 30 meters (98 feet) in open space. However, the range can be affected by various factors, such as the presence of walls and other obstacles, interference from other wireless devices, and the sensitivity of the receiving device. Therefore, the actual range may vary in different environments. As wardr states: “It’s not clear why an external antenna is not an option for the Pi 3 ”. He thought, why not including one by himself. He found that there can be two options for including external WiFi antenna. One could be more barbarian – just remove chip antenna and solder it to left top mount pad. This is more messy part as you need to scratch ground plane to make it possible to solder copper mesh. Another way is more civilized. On the bottom side of Raspberry Pi, 3 are two exposed pads where U.FL connector almost fits. Yet you still need to clear some solder masks and rotate one zero ohm…

A Guide to Choosing the Best IT Support

IT is at the crux of most businesses, whether they’re small family-run enterprises or massive global conglomerates. Successful businesses usually realize something that the others don’t, though: IT needs to be maintained and looked after constantly, and it doesn’t simply work in the background, never requiring a second thought. The more successful businesses also realize this: keeping an IT system in tip-top shape isn’t something that just anyone can do – it needs to be done by a professional company, with the experience needed to remedy problems or, even better, prevent the problems from occurring at all. There are loads of IT support companies out there, and they all say they’ll be the best choice for your company. And who can blame them for making that assertion? It’s your job to sift through them and choose the one that’s right for you though, and here are a few tips on how to go about that job…

Using Raspberry Pi sftp server

There are several ways of accessing Raspberry Pi files through the network. One of the preferred methods is to use the Secure Copy (SCP). It is a file sending command allowing transferring data over SSH. This is a secure way of sending files between Raspberry Pi boards or other Linux machines. To use with Windows, you need special software like WinSCP. As you can see, it requires additional software to access files from windows. But if you are used to transferring data via FTP, you have another option – SFTP, an FTP with encryption. SFTP is already enabled in Raspbian and can be used right away. Be sure that your FPT client supports sftp protocol. For instance, FileZilla, Bitvise, and the same WinSCP clients work without a problem. To connect to Raspberry Pi via sftp, you need to enter an IP address and port 22. Log in by using your connection credentials that are pi/raspberry by default. Once connected, you can drag and drop your files in and out. If you want to move a bit forward and connect to…
