The captive portal provides Web site redirection, which you may have encountered when surfing the Web from hotels that provide DSL access to rooms. When the Wi-Fi card in your laptop associates with the access point and you try to open a Web site, you are redirected to an introduction page that identifies the network and invites you to log on (sometimes after paying a nominal fee for access).

The hot spot has its place in any community network project because it is relatively simple to set up and provides immediate benefits. For little more than the price of the hardware, homes and businesses can use the wireless network to access a high-speed DSL line (or other appropriate network connection), sharing its cost. Sponsors can charge competitive fees for Internet access to help offset the cost of operations.
The hot spot has one critical limitation: You can set it up only where high-speed Internet access is already available. What if you want to extend network access outside of DSL and cable range, or you want to bridge two networks together but can't afford a dedicated telco line?

You may not love Microsoft Word, but you’ve definitely used it. Other than being one of the most ubiquitous programs on the planet, it’s been the go-to word processing system for more than a quarter-century because it’s as basic as it gets. But occasionally, you’ve got assignments that beg for a lot more options than simple […]
Almost everyone has their smartphone in a case of one kind or another. Beyond simple protection, finding a case that can charge your phone on its own, but doesn’t feel like it’s also adding a couple pounds to the phone’s weight is the tricky part. Billed as the world’s thinnest battery case, the ThinCharge iPhone […]
