Choosing The Right Wireless Modems

Defining wireless modems

Defining wireless modems. Wireless modems are system units that make it possible for computers to connect to a WLAN (wireless local area network) without actual cabling such as ethernet wiring. These modems work with cellular, satellite or WiFi protocols in order to connect to a WLAN, which will then supply access to the Internet. This deviates from dial-up and DSL modems which use phone lines in order to connect to the Internet, while a cable modem uses cable television lines to connect.

For mobile uses, a laptop with PCMCIA wireless modem card is enough to have access to the internet through some public hotspots. Hotspots are the places where WLANs allow public Internet access by using wireless modems. Some require a minimal amount of fee to allow Internet access, while some other hotspots are totally free. An additional well-known network for mobile wireless modems is WiFi (Wireless fidelity), which could run at a decent 400 kbps. WiFi can be used in many Internet cafs along with other hotspots. WiFiMax is a newer standard which offers even faster speeds and more features.

Considering wireless modems are known as being compatible with certain protocols and standards, you need to be certain the modem you acquire has the features required for the networks you want to connect to.

Things to consider in choosing a wireless modem. It is important to choose the best wireless modem, here's how:

1) Identify which type of wireless modem (external or internal) you need. Prior to buying either of the kinds, be sure that your computer works with the modem.

2) Identify if you will be using the wireless modem with a desktop, laptop or Smartphone. A mobile phone can also act as a wireless modem and therefore provide Internet access. But, not all mobile phones come with an in-built modem.

3) Consider the type of network to which your Internet service provider (ISP) will have access. You will need to buy a wireless modem that works with the wireless network your web service provider employs. In particular, should your ISP offers CDMA wireless Internet service, you will need to buy a wireless modem that is CDMA compatible.

4) Think about the data transfer speed of your wireless network.

5) Verify the coverage of your wireless network.

6) Evaluate the wireless modem's security features. Many wireless networks are vulnerable to threats. Subsequently, try to find wireless modems offering additional security features.

7) Make sure your wireless modem has all the necessary advanced features as well as accessories available. For example, Ethernet cable and USB connectivity, backward compatibility equipment, improved security, PC and Mac compatibility, depth, width, port connection and the type of slot.
