Wireless technologies and mobile work tend to go hand in hand. Here's a quick overview of what you need to know about wireless protocols, security, and network connections for remote work.
What is 802.11? Should I invest in 802.11n (Wireless-N) devices? You'll often see wireless networks or network devices labeled as 802.11a, 802.11b, 802.11g, or 802.11n. These are wireless technology standards that differ in terms of device compatibility, how fast information can be sent and received over the network, and how far devices can reliably be from the wireless signal source. If you're deciding on whether to buy the newest 802.11n (or Wireless-N) network device versus the more common 802.11g (Wireless-G) hardware, consider your specific usage circumstances: can you upgrade all wireless devices connecting over the network to the same protocol? Will you be connecting to wireless hotspots that only support 802.11g? Which protocols are supported by your company office? In general, 802.11g offers the greatest compatibility, but the future is in 802.11n.
What is WEP/WPA? Which is best? WEP and WPA are encryption protocols for wireless networks, designed to protect information that travels over the network. To connect to a WEP- or WPA-secured wireless network, you'll need to input the security key or passphrase for the network. WPA2 is the most recent--and strongest--encryption protocol for wireless networks today (WEP, by contrast, is not very secure).
What is a hotspot? In a nutshell, a hotspot is a public place where you can connect to a wireless network for Internet access. As long as you have a wireless-enabled device and have paid any required usage/subscription fees (if applicable), you can connect to a hotspot's wireless network and go online using their Internet service.
Where can I find free hotspots? Many retailers and dining places, such as Panera Bread and Barnes & Noble, offer free wireless Web access; some others, such as Starbucks, are free for subscribers of certain cellular providers. You may also find free wi-fi at airports, libraries, and other places where lots of people gather.
How do I connect to a hotspot/wireless access point? The process of connecting to a wireless access point (AP) or router at a hotspot is essentially the same as connecting to any other wireless AP (at home, for example, or at the office). Your wireless adapter software or your operating system will most likely let you know when you are in range of a wireless network, and then you can choose to join the wireless network (entering in the security key if necessary) after accepting the hotspot's terms and conditions.
