How to build a portable WiFi repeater using ESP32 or ESP8266
Typically, a WiFi network has a range that’s above 45 meters. The signals are strongest near the router. The further away you move, the weaker the signal. The same is true of thick walls or additional floors in a home or building. The WiFi signals could be completely lost on other floors of a premise. …
What is the LoRaWAN network and how does it work?
LoRa (“long-range”) is an excellent wireless communication solution without networking capabilities. It’s a reliable, energy-efficient, encryption-secured, low-cost wireless connectivity technology. And as its name suggests, it offers an extremely long range. LoRa operates at the physical layer of an OSI model and is implemented at the chip level — excluding the network management protocol. This…

Understanding the architecture of the Internet
The Internet consists of a plethora of networks (public, private, government etc.) which carry an abundant range of information, services and resources and connect to each other via bundles of data called packets. Everything that we use in our daily lives such as E-mail, Search Engines, VoIP, Peer-to-Peer file sharing are a result of the transference of these data packets. Shipping packets around the world involves cooperation between different organizations and can be quite challenging. Packets can also be lost during transmission due to the distance, collision or excessive crowding. This packet transfer across the Internet is made easier by Internet eXchange Points (IXP) where local networks efficiently exchange information at a common point within a country.
