Wireless IP Appliances

There has been quite a stir about broadband connectivity during the past year, and DSL and cable have been especially emphasized as convenient, reasonably priced mechanisms to deliver broadband to the residential and SOHO markets. But wireless delivery of packetized information is slowly making a statement. From the Palm and PDA devices that are gaining prominence as they entrench themselves in the data networking market, to the new breed of cellular phones that can deliver e-mail, personalized information, and Internet access -- wireless technology is staking a claim as a viable solution for broadband access.

It only makes sense that the same devices that deliver analog voice over wireless networks will be able to handle packetized voice, and while wireless VoIP is not yet prevalent, the technology to enable converged voice communications is well underway. The following appliances, services, and technologies all have one common goal: Delivery of data over existing and emerging wireless networks. So perhaps you're searching for a mobile appliance that will enable unified communications, or maybe you're a developer with an amazing idea for delivering services to a wireless device. No matter which end of the spectrum you're coming from, wireless appliances offer a broad promise for convergence -- anywhere, at any time.

13 Easy Steps To Wireless Communications Knowledge

BY EVAN KOBLENTZ, TMC LABS

Part of our jobs as TMC Labs' staff is to keep up with the latest e-technologies, from CRM to TAPI, processor chips to ZIP drives. Following our intuition about what will be the next big thing, we carved a niche as the resident experts on all things small office/home office (SOHO), which has evolved into all things mobile. So, when the INTERNET TELEPHONY´┐Ż editors came to the lab seeking a sidebar article to demystify wireless jargon, we volunteered faster than you can beam a Chinese take-out menu over infrared. Regardless of your job function, if you learn the 13 definitions below, you'll be a hit at the CEO's next cocktail party. (Please note that these technologies, terms, and organizations are listed in a logical order of construction, as opposed to the arbitrary alphabetical method.)

1. Connected Devices: The buzzword referring to the next generation of network nodes. Today, a connected device can be a PC or laptop PC, a Web-enabled mobile telephone, a Palm VII, the GPS system in your rental car, or an Internet appliance (like the ones I've gathered here). Tomorrow, a connected device might be your refrigerator, car, home entertainment system, copy machine, oven, ATM kiosk, or eyeglasses. According to companies like Microsoft, many of these devices will have operating systems and local storage; but according to Larry Ellison and Oracle, they'll all be function-specific clients to the Internet. It seems obvious to us that the paradigms will coexist for the immediate future.

2, 3, 4. CDMA, TDMA, GSM: These are the "Big Three" competing protocols for direct wireless Internet access. CDMA stands for Code Division Multiple Access -- it uses a "spread-spectrum" method, where each channel uses the whole spectrum, and individual conversations are encoded. TDMA stands for Time Division Multiple Access -- it works by dividing a radio frequency into time slots and then allocating slots to multiple calls. Meanwhile, GSM stands for Global System for Mobile Communications -- in Europe and Asia, it is the leading digital cellular technology, and it uses a narrowband version of TDMA. CDMA is the current American standard, but GSM is the superior technology, and most experts believe that it will soon become the worldwide standard.

5. W3C: W3C is the official nickname of the World Wide Web Consortium. Tim Berners-Lee, the British physicist who invented the Web, founded the W3C in late 1994. The group works with other groups, like the ITU, to develop new Web standards and to encourage interoperability, and they oversee the evolution of the massive Standard Generalized Markup Language, from which all other markup languages are born. Interestingly, the W3C is currently doing some telephony-related work, such as the Mobile Access project, the Voice Browser project, and the Web Accessibility Initiative. The W3C's American home is at MIT's Laboratory for Computer Science.

6. XML: With a <p> and </p> straddling your message, browsers can do more than simply spit out text. That's a common problem with HTML: Despite four major upgrades and support for numerous programming languages, it's still a product of the SGML that's been too dummied-down to be successful as the interactive medium beyond Y2K. So, the W3C approved eXtensible Markup Language (XML), which is a way to create new HTML-like markup languages -- called "applications" -- that are customized for the needs of an industry or organization. By authoring more precise markup languages, fellow developers can better understand your site, and browser software can take advanced action on its content. Also, XML is intended to produce browser-generic applications, so the same version of your site will work on a PC, a connected device, over a telephone, etc. Some examples of applications made with XML are MathML, for formatting mathematical explanations; SMIL, for showing online multimedia presentations; and XHTML, for next-generation Web design. But XML applications are also being developed for CRM, e-commerce, information portals, ERP, mobile communications (see WML, below), and even voice! See the "XML Catalog" link at XML.org for more information.

7. WAP: Regardless of whether your connected device uses CDMA, TDMA, GSM, or some other protocol, Wireless Application Protocol (WAP) will probably be its method of communicating with other software on the Internet. WAP features a security layer -- Wireless Transport Layer Security (WTLS), transaction layer -- Wireless Transaction Protocol (WTP), session layer -- Wireless Session Protocol (WSP), and application layer -- Wireless Application Environment (WAE). Of course, other than the occasional antenna or satellite, the primary physical layer is the atmosphere. There is also a WAP API called the Wireless Telephony Application (WTA, see the discussion in the WAP white paper).

8. WML: Software for WAP devices (primarily mobile telephones and PDAs) will be written with an XML application (see above) called the Wireless Markup Language and its cousin, WMLScript. WML pages are called "cards," and WML browsers are normally called "minibrowsers" or "microbrowsers." An excellent non-commercial FAQ is available at www.wap.colorline.no/wap-faq.

9. WAP Forum: As exciting as WAP and WML are, both technologies are far from becoming a part of the mainstream. The WAP Forum is a trade organization working toward that goal. They already have several hundred member companies, plus formal relationships with the W3C, the European Telecommunication Standards Institute (ETSI), the Telecommunications Industry Association (TIA), the Internet Engineering Task Force (IETF), and the European Computer Manufacturers' Association (ECMA). Visit them at www.wapforum.org.

10. HDML: The Handheld Device Markup Language is an interim XML application that is commonly used until WML becomes more ubiquitous. It was developed by Phone.com, which was then known as Unwired Planet. Phone.com lets anybody use HDML royalty-free; both AT&T and Sprint PCS currently use it for their "Wireless Web" services. Although HDML sites should provide the simplest possible migration path to WML, a common (but false) statement is that HDML is simply the old name for WML.

11, 12, 13. Bluetooth, Jini, Universal Plug-and-Play: These are the leading (and somewhat competing) technologies for next-generation dynamic networking. Each slightly overlaps the other, and each has unique advantages for on-the-fly connections from device-to-device and device-to-network. Bluetooth uses short-range radio signals. It was co-founded by 3Com, Ericsson, IBM, Lucent, Microsoft, Motorola, Nokia, and Toshiba. Jini, pronounced as "genie," comes from Sun and is based on Java technology. It is embedded into devices to automatically register them with a network. Because it is network-independent, it can work with Bluetooth, and it can work on wired networks as well. Universal Plug-and-Play is the Microsoft answer to both technologies; visit the UPNP site.
