In an era where wireless connectivity has become the norm, having a reliable and fast internet connection is no longer a luxury, but a necessity. However, there are instances where our devices may not have the capability to connect to wireless networks, or the built-in wireless adapter may not be providing the desired range and speed. This is where external wireless adapters come into play. But what exactly is an external wireless adapter called?
Understanding External Wireless Adapters
An external wireless adapter, also known as a wireless network adapter or Wi-Fi adapter, is a device that allows your computer or laptop to connect to a wireless network. It is typically a small, compact device that plugs into a USB port or a PCI Express slot on your computer, providing a wireless connection to the internet.
These adapters are designed to provide a wireless connection to devices that may not have built-in wireless capabilities, or to improve the wireless connectivity of devices with weak or outdated wireless adapters. External wireless adapters are available in various forms, including USB adapters, PCIe cards, and PCMCIA cards.
Types of External Wireless Adapters
There are several types of external wireless adapters available, each with its own unique features and benefits.
USB Wireless Adapters
USB wireless adapters are the most common type of external wireless adapter. They are small, compact devices that plug into a USB port on your computer or laptop. They are easy to install and use, and are compatible with most operating systems. USB wireless adapters are available in different speeds, ranging from 150Mbps to 1900Mbps.
Some popular USB wireless adapters include:
- Edimax EW-7612UAC
- Linksys WUSB6300
- Netgear Nighthawk AC1900
PCIe Wireless Adapters
PCIe wireless adapters, also known as PCIe Wi-Fi cards, are internal adapters that are installed inside your computer’s PCIe slot. They provide a more permanent solution for wireless connectivity and are generally faster and more reliable than USB adapters.
PCIe wireless adapters are available in different speeds, ranging from 300Mbps to 1900Mbps. They are compatible with most desktop computers and are ideal for those who want a more permanent and reliable wireless connection.
Some popular PCIe wireless adapters include:
- Asus PCE-AC68
- MSI Gaming Wi-Fi Adapter
- Gigabyte GC-WB867D-I
PCMCIA Wireless Adapters
PCMCIA wireless adapters, also known as PC Card adapters, are used in older laptops that have a PCMCIA slot. They are less common than USB and PCIe adapters but are still used in some legacy devices.
Key Features to Consider
When choosing an external wireless adapter, there are several key features to consider.
Speed
The speed of an external wireless adapter is measured in Mbps (megabits per second). The most common speeds available are 150Mbps, 300Mbps, 600Mbps, 1200Mbps, and 1900Mbps. The speed you need depends on your internet service provider’s (ISP) speed and your online activities.
For general browsing and streaming, a 150Mbps adapter may be sufficient. However, if you plan to stream 4K videos or engage in online gaming, a faster adapter with speeds of 1200Mbps or higher is recommended.
Range
The range of an external wireless adapter refers to its ability to connect to a wireless network from a distance. Some adapters have a longer range than others, making them ideal for larger homes or offices.
When choosing an adapter, consider the size of your coverage area and the number of obstacles (walls, furniture, etc.) that may interfere with the signal.
Compatibility
Ensure that the external wireless adapter is compatible with your operating system (Windows, macOS, Linux, etc.). Some adapters may only be compatible with specific operating systems, so it’s essential to check the product description before making a purchase.
Antenna Type
Some external wireless adapters come with external antennas, which can be adjusted to improve the signal strength and range. There are different types of antennas available, including omnidirectional, directional, and detachable antennas.
Omnidirectional antennas provide a 360-degree coverage, while directional antennas focus the signal in a specific direction. Detachable antennas can be replaced or upgraded as needed.
Benefits of External Wireless Adapters
There are several benefits to using an external wireless adapter.
Improved Wireless Connectivity
External wireless adapters can improve the wireless connectivity of your device, providing a faster and more reliable connection to the internet.
Increased Range
External wireless adapters can increase the range of your wireless connection, allowing you to connect to a wireless network from a greater distance.
Upgradeability
External wireless adapters can be easily upgraded or replaced as new technologies emerge, making them a cost-effective solution for those who want to stay up-to-date with the latest wireless standards.
Portability
USB wireless adapters are portable and can be easily carried in a laptop bag or pocket, making them ideal for those who need to work or access the internet on the go.
Conclusion
In conclusion, external wireless adapters are a convenient and effective way to improve the wireless connectivity of your device. With various types of adapters available, including USB, PCIe, and PCMCIA, there’s an adapter to suit every need and budget. When choosing an external wireless adapter, consider the speed, range, compatibility, and antenna type to ensure you get the best adapter for your needs.
By understanding the different types of external wireless adapters and their features, you can unlock wireless freedom and enjoy a fast, reliable, and secure internet connection anywhere, anytime.
What is an External Wireless Adapter?
An external wireless adapter is a device that connects to a computer or laptop via a USB port or other interface, allowing it to access wireless networks and connect to the internet.
