Description: A wireless mesh network is a network topology where each node retransmits data for the network, allowing for extended coverage and redundancy. In this type of network, devices are interconnected in such a way that each can communicate with other nodes, creating a robust and flexible structure. This architecture is particularly useful in environments where traditional connectivity is difficult to implement, such as in rural areas or emergency situations. Mesh networks can dynamically adapt to changes in topology, meaning that if a node fails or disconnects, data can be rerouted through other nodes, thus ensuring service continuity. Additionally, these networks are scalable, allowing for the addition of new nodes without the need to reconfigure the entire network. The simplicity in installation and maintenance, along with the ability to provide wide coverage, makes mesh networks an attractive option for various applications, from home connectivity to implementation in smart cities.
History: Mesh networks have their roots in the 1970s when new forms of device interconnection began to be explored. However, significant development began in the 1990s with the introduction of wireless technologies. In 1997, the IEEE 802.11 standard, which defines Wi-Fi networks, laid the groundwork for the creation of wireless mesh networks. Over the years, the technology has evolved, and in the 2000s, mesh solutions began to be implemented in urban and rural environments, highlighting their ability to provide connectivity in hard-to-reach areas.
Uses: Mesh networks are used in a variety of applications, including connectivity in rural areas where traditional network infrastructure is limited. They are also common at outdoor events, such as festivals and concerts, where a temporary and flexible network is required. Additionally, they are implemented in urban environments to create community networks that allow residents to share Internet access. Other applications include sensor monitoring in industrial settings and the creation of emergency networks in disaster situations.
Examples: An example of a mesh network is the Google Nest Wi-Fi system, which allows users to create a mesh network in their homes to improve coverage. Another example is the mesh network used in urban environments, which provides free Internet access in public spaces. Additionally, projects like ‘Freifunk’ in Germany have utilized mesh networks to offer connectivity in local communities.
