What do ipad wireless lan and cellular network mean?

Wireless LAN refers to the application of wireless communication technology to interconnect computer devices to form a network system that can communicate with each other and realize resource sharing; simply put, wireless LAN is "Wi-Fi", which is connected through a wireless router. internet. Cellular network, also known as mobile network, is a mobile communication hardware architecture. It is named because the signal coverage of each communication base station that forms the network coverage is hexagonal, making the entire network resemble a honeycomb.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Wireless LAN refers to "Wi-Fi", and cellular network is a mobile network.

Wireless LAN

Wireless LAN refers to the application of wireless communication technology to interconnect computer devices to form a network system that can communicate with each other and realize resource sharing. The essential characteristic of wireless LAN is that it no longer uses communication cables to connect computers to the network, but connects wirelessly, making network construction and terminal movement more flexible.

Cellular network

Cellular network is a mobile communication hardware architecture, which is divided into analog cellular network and digital cellular network. Because the signal coverage of each communication base station that forms the network coverage is hexagonal, the entire network is named after it resembles a honeycomb.

Summary:

Wireless LAN refers to "Wi-Fi", which is access to the Internet through a wireless router, generally free, and cellular network refers to mobile communications Network refers to a base station established by our operator, which is charged based on traffic.

The difference between ipad wireless network and cellular network

1. Different network properties:

Wireless network: It is a local area network that does not use any wires or transmission cables to connect, but uses radio waves or electric fields and magnetic fields as the medium for data transmission. The transmission distance is generally only a few dozen meters.

Cellular network: Also known as mobile network, it is a mobile communication hardware architecture, which is divided into analog cellular network and digital cellular network.

2. Different features:

The wireless network does not charge a fee and can only be used in places with wifi, and the speed is faster.

Cellular networks are charged based on mobile data traffic and can be used anywhere with wide coverage.

3. Price:

Models that support cellular networks are relatively more expensive. The reason is that the models add mobile communication technology and support mobile phone cards, so the price is higher.

Extended information

The cellular network mainly consists of the following three parts: mobile station, base station subsystem, and network subsystem. system. The mobile station is our network terminal equipment, such as mobile phones or some cellular industrial control equipment.

The base station subsystem includes the mobile base stations (large towers) we see every day, wireless transceiver equipment, dedicated networks (usually optical fiber), countless digital devices, etc. We can think of the base station subsystem as the converter between the wireless network and the wired network.

According to different wireless network topologies, wireless networks can be divided into different types. As we all know, in wired networks, there are five major network topologies, namely Bus, Token Ring, Star, Tree and Mesh.
