Sabia que para jogar com seus amigos ou trocar mensagens com seus colegas de trabalho ou até para trocar ficheiros, não precisa necessariamente de estar conectado à internet? É isso mesmo! A intranet, uma rede interna da sua empresa ou escola ou até mesmo do seu prédio permite que faça tudo isso sem precisar de uma ligação com a internet.
Imagine a intranet como uma pequena internet só sua, onde pode acessar ficheiros, programas e serviços exclusivos para os utilizadores daquela rede. Para criar essa rede, é utilizado um router que conecta todos os computadores, formando uma espécie de rede local.
Vantagens da intranet:
Independência da internet: Você pode jogar, conversar e trabalhar mesmo quando a internet está instável ou indisponível.
Segurança: A intranet é uma rede privada, o que significa que suas informações estão mais seguras e protegidas.
Velocidade: Ao utilizar a intranet, você pode ter uma conexão mais rápida e estável, ideal para atividades que exigem muito banda larga, como jogos online.
Após esta breve introdução e a apresentação de conceitos que podem agora ser aplicados na prática — talvez até mesmo de forma inesperada —, imagine a seguinte situação: em um prédio, dois jovens amigos residem, um no primeiro andar e outro no terceiro. O morador do primeiro andar adquire um roteador de baixo custo, como o MI Router (cerca de 15 euros), que também pode funcionar como repetidor. Devido ao baixo consumo de energia (5V), é uma opção extremamente econômica e extremamente versátil. Ao utilizar painéis solares para alimentar o roteador, ele pode ser instalado em qualquer lugar, mesmo em áreas sem tomadas, tornando a conexão Wi-Fi ainda mais prática e acessível.
No passado, um grupo de amigos e eu demonstramos notável engenhosidade técnica ao estabelecer uma intranet a uma distância de 5 km usando antenas WiFi unidirecionais. Desenvolvemos até um programa de chat customizado em Visual Basic, aprimorando ainda mais essa rede de comunicação única. Esta experiência destaca a desenvoltura e o espírito colaborativo que podem ser promovidos através de tais projetos.
Hoje, formas mais simples de rede locais estão prontamente disponíveis. Ao configurar uma rede Wi-Fi chamada “KIDS-GAMES”, por exemplo, a conexão entre dispositivos torna-se automática, facilitando a jogatina. É importante ressaltar que nem todos os jogos suportam esse tipo de ligação direta, e que uma rede, mesmo local, oferece uma ampla gama de funcionalidades além dos jogos.
Existe esta tendência de os utilzadores esquecerem-se da conveniência de partilhar ficheiros e outros conteúdos diretamente entre os seus dispositivos, sem a necessidade da Internet ou a cloud.
Did you know that to play with your friends or exchange messages with your work colleagues or even to share files, you don't necessarily need to be connected to the internet? That's right! The intranet, an internal network of your company or school or even your building, allows you to do all this without needing an internet connection.
Imagine the intranet as a small internet of your own, where you can access files, programs and services exclusive to users of that network. To create this network, a router is used that connects all computers, forming a type of local network.
Advantages of the intranet:
Internet independence: You can play, chat and work even when the internet is unstable or unavailable.
Security: The intranet is a private network, which means your information is safer and more protected.
Speed: When using the intranet, you can have a faster and more stable connection, ideal for activities that require a lot of bandwidth, such as online games
After this brief introduction and the presentation of concepts that can now be applied in practice — perhaps even in an unexpected way —, imagine the following situation: in a building, two young friends live, one on the first floor and the other on the third. The resident on the first floor purchases a low-cost router, such as the MI Router (around 15 euros), which can also function as a repeater. Due to low power consumption (5V), it is an extremely economical and extremely versatile option. By using solar panels to power the router, it can be installed anywhere, even in areas without sockets, making the Wi-Fi connection even more practical and accessible.
In the past, a group of friends and I demonstrated remarkable technical ingenuity by establishing an intranet across a 5km distance using unidirectional WiFi antennas. We even developed a custom chat program in Visual Basic, further enhancing this unique communication network. This experience highlights the resourcefulness and collaborative spirit that can be fostered through such projects.
Today, simpler forms of local networking are readily available. By configuring a Wi-Fi network called "KIDS-GAMES," for example, the connection between devices becomes automatic, facilitating easier gaming. It's important to note that not all games support this type of direct connection, and that a network, even a local one, offers a wide range of functionalities beyond just gaming.
There's is this tendency for users to forget about the convenience of sharing files and other content directly between their devices without the need for internet connectivity or cloud storage.
Setting Up a Local Wi-Fi Network (Without Internet) : A Step-by-Step Guide
Creating a local Wi-Fi network might seem daunting, but it's surprisingly easy! This guide will walk you through the process of setting up a wireless network that connects your devices without requiring an internet connection. This is perfect for situations like gaming with friends, sharing files among devices in a small office, or simply enjoying a more private and secure network.
Step-by-Step Tutorial:
Gather Your Equipment:
Wireless Router: Choose a router that supports local network creation (most modern routers do).
Ethernet Cable (optional): If your router doesn't have built-in Wi-Fi, you'll need this to connect it to a computer for initial setup.
Connect the Router:
Power: Plug the router into a power outlet.
Optional: Connect to Computer: If necessary, connect the router to your computer using the Ethernet cable.
Access Router Settings:
Find the Router's IP Address: This is usually found on a sticker on the bottom of the router.
Open a Web Browser: Type the router's IP address into the address bar and press Enter.
Login: Enter your router's default username and password (often found in the router's documentation).
Configure the Network:
Network Name (SSID): Choose a name for your local Wi-Fi network.
Security: Set a strong password to protect your network from unauthorized access.
Save Settings: Click "Save" or "Apply" to apply your changes.
Connect Your Devices:
Find the Network: On each device, search for available Wi-Fi networks.
Connect: Select your newly created network and enter the password.
Enjoy Your Local Network:
Share Files: Easily transfer files between your devices.
Play Games: Enjoy local multiplayer games with friends.
Create a Private Network: Share files and communicate within a secure and private environment.
Tips & Considerations:
Device Compatibility: Ensure all devices you want to connect are Wi-Fi enabled.
Router Placement: Position the router centrally for optimal Wi-Fi coverage throughout your space.
Firmware Updates: Keep your router's firmware updated for improved performance, security, and bug fixes.
Guest Network (Optional): If you need to provide temporary Wi-Fi access to others, consider creating a separate guest network with its own password.
Troubleshooting: If you encounter any issues, check the router's documentation or contact your internet service provider for assistance.
