Connect to the Internet using wireless technology or WiFi

Offering faster browsing and more mobility than dial-up, WiFi Internet connections allow you to get online without plugging your computer directly into a phone outlet. Instead, a WiFi router is connected to your phone line, providing a signal your wireless Internet accessible computer will pick up. Many public places, including restaurants, coffee shops and other businesses, also offer wireless Internet access to their customers for free or for a small fee. Wireless service can be obtained from phone service, cable, satellite and local and national Internet service providers, which build a wireless network for a city/region or large pool of users, respectively.

I recommend: Frequent travelers and business owners hoping to work outside their office may want to purchase an annual subscription to a wireless service like T-Mobile HotSpot, which offers wireless Internet connectivity in many airports, hotels and Starbucks for about $30 a month. Learn where HotSpots are and register on T-Mobile's site. Boingo is another WiFi provider, with global service and day-only rates; it's wireless rates are as low as $21.95 a month.

Make calls with a wireless technology cell phone

Cell phones now provide more than just free long distance. Phones with GPS receivers can instantly provide maps and driving directions via a GPS navigation wireless service subscription or a software package. Prepaid cell phones may require you to buy a phone, but will offer infrequent users the option to pay as they go for wireless service, as opposed to paying a set monthly fee. Smart phones can also offer employees one-stop tech shopping, providing a cell phone, e-mail capabilities and more. An e-mail and smart phone wireless service designed specifically for small business owners costs about $30 to $40 per month.

I recommend: Choose a phone that can also wirelessly exchange information with your computer, like the BlackBerry Pearl. AccuTracking GPS software works on Motorola iDEN cell phones or RIM BlackBerry phones carried by Nextel and Boost Mobile. Nextel also offers GPS wireless service for BlackBerry and Sprint phones that give directions and tracks asset, inventory, job and event data.

Use Bluetooth wireless telecommunications

Bluetooth technology allows you to securely connect PDAs, computers, cameras and phones by creating a wireless network with a low-power radio spectrum. It's similar to WiFi, and can interact with a wireless network, but Bluetooth functions on a shorter, three to 30 foot range. Bluetooth can increase mobility by connecting headsets and cell phones and computer calendars and contact lists into a wireless network.

I recommend: To check and see if your current phone, computer or other device features Bluetooth wireless network capabilities, check out the company's product directory. Bluetooth also allows you to select specific tasks and design solutions using its Assembler feature.

Use a wireless technology router

Most notebook computers now come with WiFi capability. However, a wireless technology router may be needed to help non-wireless desktop computers connect wirelessly to the Internet. Wireless routers use radio signals or Ethernet cables to connect computers -- and to connect them to the Internet. Most give about 100 feet of coverage, making a wireless network work well in a home office. A mobile router also can help employees on the road quickly connect multiple devices to the Internet using a cell phone signal in their car, hotel or elsewhere. Some companies use mobile routers in branch offices where employees only need limited wireless Internet access.

I recommend: PC Magazine picked the Kyocera KR1 as the top mobile router in a recent comparison because of its easy set-up and ability to share Alltel, Sprint or Verizon service. With a data-capable cell phone connected to a USB port on the device, the KR1 will give several computers high-speed wireless service.
