Mobile Application Development: Web vs. Native

Web apps are cheaper to develop and deploy than native apps, but can they match the native user experience?

Java in a Teacup

Few technology sectors evolve as fast as the wireless industry. As the market and devices mature, the need (and potential) for mobile applications grows. More and more mobile devices are delivered with the Java platform installed, enabling a large base of Java programmers to try their hand at embedded programming. Unfortunately, not all Java mobile devices are created equal, presenting many challenges to the new J2ME (Java 2 Platform, Micro Edition) programmer. Using a sample game application, this article illustrates some of the challenges associated with J2ME and Bluetooth programming.

Streams and Standards:
Delivering Mobile Video

Don’t believe me? Follow along… Mobile phones are everywhere. Everybody has one. Think about the last time you were on an airplane and the flight was delayed on the ground. Immediately after the dreaded announcement, you heard everyone reach for their phones and start dialing.

Mobile Media:
Making It a Reality

Many future mobile applications are predicated on the existence of rich, interactive media services. The promise and challenge of such services is to provide applications under the most hostile conditions - and at low cost to a user community that has high expectations. Context-aware services require information about who, where, when, and what a user is doing and must be delivered in a timely manner with minimum latency. This article reveals some of the current state-of-the-art "magic" and the research challenges.

Enterprise-Grade Wireless

We have been working in the wireless space in one form or another in excess of 10 years and have participated in every phase of its maturation process. We saw wireless progress from a toy technology before the dot-com boom, to something truly promising during the boom, only to be left wanting after the bubble when the technology was found to be not ready for prime time. Fortunately, it appears that we have finally reached the point where the technology and the enterprise's expectations have finally converged.

A Conversation with Teresa Meng

In 1999, Teresa Meng took a leave of absence from Stanford University and with colleagues from Stanford and the University of California, Berkeley, founded Atheros Communications to develop and deliver the core technology for wireless communication systems. Using a combination of signal processing and CMOS RF technology, Atheros came up with a pioneering 5 GHz wireless LAN chipset found in most 802.11a/b/g products, and continues to extend its market as wireless communications evolve.

Wireless Networking Considered Flaky

You know what bugs me about wireless networking? Everyone thinks it's so cool and never talks about the bad side of things. Oh sure, I can get on the 'net from anywhere at Usenix or the IETF (Internet Engineering Task Force), but those are _hostile_ _nets_. Hell, all wireless nets are hostile. By their very nature, you don't know who's sharing the ether with you. But people go on doing their stuff, confident that they are OK because they're behind the firewall.

Open Spectrum:
A Path to Ubiquitous Connectivity

Just as open standards and open software rocked the networking and computing industry, open spectrum is poised to be a disruptive force in the use of radio spectrum for communications. At the same time, open spectrum will be a major element that helps continue the Internet's march to integrate and facilitate all electronic communications with open standards and commodity hardware.

Designing Portable Collaborative Networks

Peer-to-peer technology and wireless networking offer great potential for working together away from the desk - but they also introduce unique software and infrastructure challenges. The traditional idea of the work environment is anchored to a central location - the desk and office - where the resources needed for the job are located.

The Family Dynamics of 802.11

Three trends are driving the rapid growth of wireless LAN (WLAN): The increased use of laptops and personal digital assistants (PDAs); rapid advances in WLAN data rates (from 2 megabits per second to 108 Mbps in the past four years); and precipitous drops in WLAN prices (currently under $50 for a client and under $100 for an access point).
