First Look: First Look: iTunes Wi-Fi Music Store at Starbucks

The joint partnership between Apple and Starbucks to let iPhone and iPod touch users wirelessly shop for recently played music at the coffee retailer debuted in select cities Tuesday, and Glenn Fleishman was on hand to sample the service. It's a promising offering, though there were a few glitches and one regrettable technology decision.

AirPort Extreme Base Station with Gigabit Ethernet

This isn't just a minor update to the AirPort Extreme Base Station Apple introduced earlier this year. By adding Gigabit Ethernet, Apple has boosted performance, raising the bar for its wireless networking product.

Securing your iPhone's traffic

Glenn Fleishman looks at how securely the iPhone handles wireless data when it surfs the Web and sends e-mail.

First Look: Finding Wi-Fi hotspots with the iPhone

iPhone users will have two choices for connecting to the Internet—the EDGE cellular data standard, which can be slow as molasses, or Wi-Fi. Glenn Fleishman walks you through your Wi-Fi options, including finding a hotspot connection.

New AirPort, old network

Apple’s new AirPort Extreme Base Station, based on the still-in-progress IEEE 802.11n standard, can wirelessly transmit more than 90 megabits per second (Mbps) of data.

Redirect domain names

Registering more than one domain name to point to a single Web site isn’t unusual. Nor is it strange to host a Web page at an ISP or community site and want a subdomain to bring people directly to what’s often a long and hard-to-remember URL. Redirection is the answer.

Three for the road

If you travel with any regularity, chances are you have your favorite tricks for making each trip go as smoothly as possible. Here are a few more techniques to add to your repertoire, from three of our mobile Mac experts.

AirPort Extreme Base Station

Apple's new AirPort Extreme Base Station may have been a long time coming, but it's worth the wait for anyone whose network needs either greater speed or longer distance. While cheaper 802.11n gateways are already on the market, none matches Apple's for features or ease of setup.

Analysis: iPhone and the emergence of convergence

There's a big push toward convergence -- the combination of different kinds of services into one -- and the iPhone could be at the center of this trend. Glenn Fleishman explains.

Inside 802.11n

The alphabet soup of wireless networking standards—a, b, g, and now n—is enough to make even the most dedicated techie’s head swim. Glenn Fleishman wades through the wireless confusion to tell you what to expect with 802.11n, the standard Apple now supports with is new AirPort Extreme Base Stations.

Symbian: Worldwide dominance, U.S. absence

You may have noticed that one smart phone platform is missing from the larger story: Symbian OS. Although Symbian runs roughly 70 percent of all smart phones worldwide, it has barely a toehold in the United States.

Get in Sync

In the U.S., cell phone providers are most likely to offer phones that run Palm OS, Windows Mobile, or BlackBerry software. Unfortunately, most of these companies don’t have Mac users’ best interests in mind when they create their phones. But with the right smart phone and the right software, you can make your phone and your Mac talk.

Living in a 3G world

Over the past year, a new option for getting online wirelessly—third-generation (3G) cellular data networks—has become increasingly practical for Mac users. In 2007, expect more hardware options, better network coverage, and (unfortunately) some confusion as new 3G network standards come on line.

Airport takes off

Thanks to Apple’s AirPort technology, every Mac is capable of wireless networking. In 2007, that technology is going to get a significant speed boost.
