Phone, handheld makers tempt Java developers
By Matt Berger
March 25, 2002 6:16 pm PT

SAN FRANCISCO - Sun Microsystems is thinking small when it comes to Java, but only in terms of the computing devices that will support the programming language.

At its JavaOne Developer Conference here, Sun and a number of partners building hardware and software based on Java announced new efforts and products that are helping to take the Java community past its competition in the market for building and delivering applications to small devices such as cell phones and handheld computers.

These companies are centering their work on J2ME (Java 2 Micro Edition), a standard set of blueprints that hardware and software makers can use when designing products. By the end of the year, Sun said it expects that about 50 million devices will be shipped with Java built in. That number is expected to balloon to about 400 million in the next two years, the company said.

One newcomer to the effort is Research In Motion, which made its entry into the Java world on Monday, announcing a new IDE (Integrated Development Environment) that allows developers to build applications in Java to run on its wireless BlackBerry device.

(excerpt)

Motorola announced a Bluetooth Java specification developed by the Java Community Process that will allow Java applications to be delivered over Bluetooth, a local wireless network technology. For example, it would allow the applications to be transmitted from a cell phone to a handheld computer.

The Schaumburg, Illinois, communication technology company also announced it is participating in the development of MIDP (Mobile Information Device Platform), the next version of the technology profile for Java-based cell phones. MIDP, which also is being jointly developed by the Java Community Process, will add new support for sound, multimedia, security and networking.

Finally, Sun itself will discuss here this week the next version of its Forte for Java developer tools, which will be available for the first time in a wireless edition.

Industry Group Nears Release of PDA Profile For J2ME
By Kristen Kenedy, CRN
San Francisco
5:58 PM EST Thurs., Mar. 28, 2002
A group of industry leaders is close to releasing a specification that will improve Java performance on handheld computers.
PalmSource, the new Palm division that licenses the company's popular mobile operating system, is leading the effort to create a PDA Profile for Sun's Java 2 Micro Edition (J2ME). The specification is made up of a group of APIs designed to enhance Java performance for Palm's handhelds, Microsoft's Pocket PCs and other PDAs.

Bluetooth: Finally Making An Impact
Home Toys Article
- April 2002 -
by Navin Sabharwal, Allied Business Intelligence

The outlook for Bluetooth technology is once again positive, albeit cautiously so. Bluetooth at its core is an embedded play. The desire to purchase add-on, aftermarket Bluetooth solutions is limited. For Bluetooth to succeed integration cost and power consumption are key determinants.

For all the negative press that Bluetooth technology garnered in 2001 this year is turning out to be a different story. Bluetooth is far from dead and we are seeing the technology begin to make its long-awaited impact.

Clearly early expectations regarding Bluetooth adoption were over-inflated. However, there is now a cautious optimism that the worst is over and what is needed moving forward is realistic expectations and solid execution.

The Problems

In retrospect many of the obstacles that Allied Business Intelligence (ABI) had cautioned against did indeed manifest themselves. These problems included:

Hype - Probably the single biggest problem with the Bluetooth story was hype, not unexpected in the heady days of the tech boom. Though the hype did generate interest, which in turn encouraged tangible development of Bluetooth solutions it also sowed the seeds for a backlash when the technology stumbled in the early stages.

Cost - First generation Bluetooth solutions were a far cry from the promised $5 dollar target. In retrospect the oft-touted $5 figure was nothing more than a target to be reached. Many companies eager to adopt Bluetooth were disappointed when faced with the high price of first generation Bluetooth solutions.

A Flawed Specification - The 1.0b specification was not fully defined and was found to have a number of bugs. Not surprisingly many of the first generation Bluetooth products were not interoperable due to incompatible chipsets. This was always a concern for a technology that would be implemented by dozens of different vendors into a variety of different products. The lack of interoperability meant that the first wave of Bluetooth solutions was essentially orphaned as companies waited for the next revision of the specification (version 1.1).

Lack of Windows OS Support - The lack of a stable specification and the scarcity of interoperable products available for testing led Microsoft to not integrate the Bluetooth protocol stack into Windows XP. This was a major blow for the industry as Microsoft was one of the Promoter companies of the Bluetooth Special Interest Group (SIG).

Mobile Handset Market - The slowdown in the mobile handset market and the delay in the introduction of 2.5G handsets also affected the fortunes of Bluetooth technology. The core group of Bluetooth backers includes the major handset vendors (Ericsson, Nokia and Motorola), and these companies intended to introduce Bluetooth functionality starting in their high-end 2.5G handsets. The slippage in GPRS (General Packet Radio Service) handsets in particular had an unavoidable knock-on impact on Bluetooth adoption.
Better Days Ahead

ABI believes there are now clear signs that Bluetooth technology has turned the corner, and the technology is poised to gather momentum in 2002. Important indicators of this trend going forward are:

Stable Specification - Probably the biggest positive for Bluetooth going forward is that the problems plaguing the technology are being dealt with. The 1.1 specification has proven to be fairly stable, and is providing a good foundation for Bluetooth development. There are far fewer reports of interoperability problems, though undeniably issues remain.

Focus on Core Strengths - Players have realized that given the limitations of Bluetooth that the technology's pervasiveness will be limited to applications in which very high data throughput and range are not paramount. The technology will be driven by a core set of applications, with an emphasis on cable replacement scenarios. More advanced applications will develop, but they will require time before they are ready for mass-market adoption.

Silicon - While the silicon costs are still higher than many envisaged it is encouraging to see costs coming down despite a lack of significant ramp-up in volume. While the potential overlap with 802.11b remains an issue many industry observers increasingly realize that both wireless LANs and Bluetooth will coexist. Indeed Bluetooth chipsets out-shipped 802.11b chipsets by roughly a 2:1 ratio in 2001.

Microsoft Support - Microsoft has also indicated that it will be including the Bluetooth protocol stack in the service pack for Windows XP, and future Windows operating systems. This has greatly mollified industry fears regarding Microsoft's commitment in supporting Bluetooth.

Greater Visibility of Products - Even though Bluetooth products are still scarce in North America there is a growing list of certified products that are beginning to hit the market. The SIG announced in March this year that it had certified over 500 Bluetooth solutions. Many of these solutions are becoming widely available in Asia-Pacific (especially Japan) and Europe. Greater presence of Bluetooth-enabled solutions in North America will happen towards the middle of 2002.
Coexisting With 802.11-based Wireless LANs

Bluetooth has been thought of as a short-range wireless connectivity technology that was based on the concept of a personal area network (PAN). Few people have seriously argued that Bluetooth could support a real wireless LAN. Proper wireless LAN technologies, such as 802.11b, have higher data rates and can transmit over longer distances (typically a few hundred feet). In addition they support for complex enterprise features such as roaming/handover.

Though few people thought Bluetooth could displace 802.11b, there have been some comments to the opposite effect. Some observers have argued that with declining IC costs wireless LANs would kill Bluetooth. Though there is undoubtedly some overlap between wireless LANs and Bluetooth such comments betray a lack of a proper understanding as to the advantages of Bluetooth over 802.11b.

Bluetooth chipsets currently are available for about half the cost of 802.11b solutions. More importantly Bluetooth chipsets offer significantly lower power consumption and smaller form factors. These three key differentiators (cost, power consumption and form factor) mean that Bluetooth is far superior in certain applications in comparison to 802.11b. Conversely applications that require higher data rates and range will be dominated by 802.11b. So the real question to ask is which set of applications will each technology dominate in.

In any case many device vendors have intimated their willingness to implement both 802.11b and Bluetooth, providing the incremental cost is not significantly higher than an 802.11b-only solution. The biggest obstacle outside the actual module implementation has been how to allow both technologies to coexist. This is critical because Bluetooth can (depending on the network topology) cause significant interference to 802.11b operation. Bluetooth itself is far less susceptible to interference from 802.11b.

Solutions to this problem will potentially take a number of different forms. Most importantly the Bluetooth SIG and the IEEE are working on adaptive hopping. Essentially this means that Bluetooth solutions will be able to sense the presence of 802.11b channels in operation and will modify their hop pattern so to operate in the portion of the spectrum not occupied by 802.11b.

In any case many industry participants are hopeful that 802.11a, the next generation wireless LAN operating in the 5 GHz band, will be rapidly adopted. If this happens wireless LANs can migrate into 5 GHz spectrum leaving the 2.4 GHz band for Bluetooth.

The Outlook

The outlook for Bluetooth technology is once again positive, albeit cautiously so. Bluetooth at its core is an embedded play. The desire to purchase add-on, aftermarket Bluetooth solutions is limited. For Bluetooth to succeed integration cost and power consumption are key determinants. The evidence is that the kinks with Bluetooth technology are being worked out and as silicon vendors develop more cost-effective solutions this will positively impact shipments of Bluetooth-enabled solutions.

Ruining (Bluetooth and 802.11) Interference
15:00 PM GMT on Apr 09, 2002
[CommVerge]

A few months ago, some technology observers were predicting the demise of the Bluetooth wireless technology before it ever got off the ground. It would be done in, they said, by 802.11b (Wi-Fi) wireless-LAN technology. There wasn't room in the marketplace for both, they said.

They were wrong, because their conclusions were based on a misguided comparison of Bluetooth and 802.11b for application as a LAN. The two serve very different purposes and simply don't compete in the marketplace (see the sidebar, "Different animals").

Hoi 'angelseye2000',

Ik begrijp dat je ons op de hoogte wilt brengen van enkele Bluetooth ontwikkelingen. Er zijn echter twee dingen waar ik me een beetje aan stoor:

- je plaatst nogal lange lappen engelse tekst op een Nederlandstalig forum
- je plaatst acht(!) berichten die nogal veel op elkaar lijken, en in ieder geval over hetzelfde onderwerp gaan. 1 bericht getiteld 'Recente bluetooth ontwikkelingen' was beter geweest.

Als je dan ook de moeite had genomen om eea. kort in het Nederlands samen te vatten en verder via URL's naar de relevante informatie verwees, was het helemaal perfect geweest.

Ik heb de acht threads samengevoegd tot eentje.

Fjodor.

Hi fjodor,

Ik had inderdaad beter de Bluetooth berichten onder 1 onderwerp kunnen plaatsen. Denk dat de "lappen engelse tekst op een Nederlandstalig forum" niet echt een probleem zijn (hopelijk). Neem aan dat iedereen engels op school heeft gehad. 7 v/d 8 berichten gaan over Bluetooth inderdaad.....begrijp echter niet waarom je het Extended Systems PC Magazine Synchronisatie bericht ook onder het onderwerp Bluetooth geplaatst heb. Dit bericht heeft niets met Bluetooth te maken, ook al is Extended Systems 1 van de leiders op het gebied van Bluetooth Software.

Zal voortaan wat meer samenvatten en bedankt voor je reactie.

gr,

wim

[fjodor]

Wim,

Dat laatste heb je gelijk in. Heb ik hersteld.

Hi Wim,

Ik sluit me aan bij de mening van Fjodor: Palmclub is een Nederlandse site, engelstalige sites zijn er meer dan genoeg. En het is gebruikelijk om een kort bericht te plaatsen, samengevat met de belangrijkste punten met een verwijzing naar een andere site voor meer info.

Susan

Hi Susan,

Dacht dat we het 1 en ander al besproken hadden omtrend eng-ned, samengevatte berichten etc.?

Nogmaals. Voortaan zal ik wat bondiger zijn met info. Voor mij is info info, zeker als het betrekking heeft met het onderwerp (Palm) en het meerwaarde heeft (Heb je de artikelen gelezen? Wat vind je v/d inhoud?). Ik lees erg weinig interesante artikels over Bluetooth en Wireless in het algemeen in Nederlandse kranten of magazines. "gebruikelijk om een kort bericht te plaatsen"? Hoeveel woorden mag ik maximaal gebruiken per bericht????? Ik hoop dat het voortaan nog toegestaan is om een engels artikel alleen nog maar te vermelden met onderwerp en link.

gr,

[Hans Keesom]

allemaal mooi en aardig maar wat ik nou wel wil is dat ik via bluetooth naar een apparaatje kan verbinden dat vervolgens zelf een verbinding met wifi maakt als dat beschikbaar is. En dat dan in een apparaat dat in m'n tas of jas past. Een soort pan naar wlan adapter.

Is er al zoiets?

[metck]

Je bedoelt dat je via BT op je pda verbinding maakt met je desktop-pc die vervolgens een signaal naar de wireless router zendt om verbinding te maken met internet. Kun je iets concreter zijn, want ik begrijp niet goed wat je bedoelt.

[Hans Keesom]

Als je nou inplaats van die desktop pc een draagbare module denkt van 10 * 5 * 2 cm of zo die z'n eigen stroomvoorziening heeft, ja dan wel.

Liefst zit er ook nog een slot in voor een gprs sim kaartje...

[metck]

Het liefst zou je dus een Treo 650 hebben met Wifi mogelijkheden .

[Hans Keesom]

komt het wel op neer, maar dan niet zo groot als de wifi case die er al is. Misschien dat ze dat ding kunnen aanpassen, dat ie niet aan de Treo 650 hoeft te zitten maar via bluetooth met de treo communiceert
