A wireless network connection allows users to connect their server, computer, or mobile phone networks without the use of any kind of wire cables.
Using a wireless network, enterprises and private owners are able to avoid the expensive and strenuous process of installing cables. There is no need for wired devices between equipment in different locations and into the buildings.
Wireless network router, for example, allows for simultaneous connection sharing between various wireless accessories for a better performance experience. Wireless networks make use of radio waves to allow devices to connect. They can connect devices such as laptops, mobile phones, and smart televisions to the internet or other applications.
When users have their wireless devices connected to Wi-Fi hotspots in public places, the connection remains established to that particular business network. While installing a new wireless networking device in homes or offices, users must consider several things. One of the most important ones is the unit's compatibility with other wireless accessories
Wireless Networking Devices
Fast and reliable internet connectivity is guaranteed when users pick the right set of networking devices for home and office networks. Wireless devices come in different varieties. These different types of networking devices only function to suit users' connectivity requirements. Wireless routers connect devices to the internet for high-quality streaming and surfing. They also improve users' streaming experience and other internet activities.
In most cases, wireless networking devices help users get their work done easily with lesser stress. They ensure fast and reliable internet connectivity at all times.
You can choose the right device for your needs from a wide selection of AllHDD wireless devices. We have new and refurbished devices like 1 to 8-port interface cards, external 3G and 4G modems, wireless access points with the speed range from 11MBps up to 5.2GBps and everything in between.
Main Types of Wireless Networks
There are four main types of wireless networks:
Wireless Local Area Network (LAN)
This type of network links two or more devices using a wireless connection method. It provides a connection via access points to a wider internet. Wi-Fi is the most commonly known and used wireless LAN type.
A local-area network is one that exists at a single location—an office building, for instance. LANs can be used to connect a wide array of accessories, such as scanners, printers, and even data storage devices.
The known components of LANs include switches, access points, routers, firewalls, and Ethernet cables.
Wireless Metropolitan Area Networks (MAN)
A metropolitan-area network is one that spreads across a city, small geographical area, business area, or even college campuses. One distinguishing factor that differentiates MANs from LAN is the coverage capacity or size. LANs usually provide a network for a building or specific area.
While MANs, on the other hand, covers several square miles depending on the desires and requirements of the organization using it. Large scale companies often obtain MANs to level up with their needs.
This happens most especially in situations whereby a company has a spacious organization. Then, they have the need to manage important components such as climate control and electrical systems.
Wireless Wide Area Network (WAN)
A wide-area network covers an incredibly vast area. It can be a whole city, an entire state, or even a country. The internet everyone uses today is an apt example of WAN access. Just like the internet, a WAN consists of smaller networks, such as the LANs or MANs.
The cellular service we get on our mobile devices today is the most commonly known example of wireless Wide Area Networks. It is always available everywhere we go within the country.
Wireless Personal Area Network (PAN)
Personal-area networks consist of a network mainly concentrated around the devices of a single person in a particular location.
A PAN could have a mobile phone, computers, video game consoles, or other auxiliary devices. They are regular home devices and small office devices. A well-known example of a wireless PAN is Bluetooth.
