Zing-based DAPs to offer Sirius, downloading over WiFi
There's a new player in town looking to expose the Music Gremlin to some harsh sunlight, and with Sirius and VoIP capabilities along with the Gremlin-like WiFi and Bluetooth for sharing and downloading, the Zing reference device may prove to be a formidable nemesis for the player we first caught at CES. Cnet was hanging out at the D4 conference today and got to check out the Zing in action, and report that the device will enable third-party content providers to offer convenient PC-less download services, although unfortunately the Sirius-branded version will get its radio content not from satellites or terrestrial repeaters but solely through relatively short-range WLAN connections. Still, the built-in mic means that Zing-based products could potentially incorporate VoIP services as well, which would make them serious contenders for some of the musicphones on the market if not for their limited utility outside the range of a hotspot.[Via Orbitcast, thanks to everyone who sent this in]
POSDATA shows off WiBro PDAs for Korea
When a manufacturer takes styling cues from a number of popular devices -- in this case, the RAZR, the Wizard, and the gone-but-not-forgotten Clie -- and throws in a number of high end features whose acronyms make us a little weak-kneed, the resulting products are bound to be pretty sexy. Such is the case with a trio of WiBro-capable PDAs being marketed under the Flyvo brand by POSDATA, all of which run Windows CE 5.0 Professional Plus on an ARM processor and let you get your 'net on with WiFi as well in case you have to travel outside of Korea. Introduced at this year's Wireless Broadband World Forum, these upcoming devices (which frustratingly lack either names or model numbers) also feature either 512MB or 1GB of flash RAM, with two of them adding T-DMB and VoIP capabilities, and the high-end model throwing in a little GPS action to boot. Lucky Koreans will be able to pick these up -- and possibly even drop their cellphone services altogether -- sometime early next year.

IEEE source: draft 802.11n timeline slipping yet again
More bad news for MIMO fans (if there is such a thing): Glenn Fleishman over at Wi-Fi Net News is reporting that an IEEE member has informed him of a delay in the timetable for expected approval of the final draft of the 802.11n Wi-Fi standard, from sometime this summer to late fall or even early winter. Fleishman's source claims that Task Group N received around 12,000 comments on the proposed draft -- compared to the 2,000-some that most drafts generate -- which is yet another bad sign following the group's earlier failure to garner even a simple majority in favor of the current proposal, much less the 75% supermajority needed for passage. With draft approval seemingly several months off at the least, it could be a year or even a year and a half before a final 802.11n standard is ratified, meaning that those folks who are already snatching up pre-N gear will have to wait even longer to find out if their hardware ends up being compatible.[Via Ars Technica]
IEEE "Task Group N" rejects first 802.11n draft proposal
In a move that came as little surprise to those who know how these things work, but that will still probably hurt manufacturers who've been releasing MIMO-enabled networking peripherals for the last few months, the IEEE 802.11 working group tasked with creating a next-gen WiFi standard has recently rejected the first draft of the highly-anticipated 802.11n. Not only did the first 802.11n draft fail to capture the 75% supermajority needed for passage, it couldn't even muster a regular majority among "Task Group N," which is a troubling development for those consumers who have already gone out and purchased pre- or draft-N gear from Linksys, Netgear, and the like. As we've reported in the past, some manufacturers had warned -- and independent testing corroborated -- that draft-N gear could negatively effect current 802.11b/g products already on the market, by hogging the available 2.5GHz bandwidth and causing performance issues on existing WLANs. Still, taken in a historical perspective, rejection of the first draft of a proposed 802.11x specification is not uncommon, and actually seems to be the rule, rather than the exception, in the life-cycle of these multi-year, multi-party standards talks.
Linksys touts draft 802.11n gear interoperability
Despite earlier concerns voiced by chipset manufacturer Airgo that draft 802.11n gear will "degrade" or "disable," current 802.11b/g networks, Linksys claims that it has tested and approved its upcoming suite of draft-n routers and adapters for interoperability with current products on the market. Since 802.11n relies on the multiple channel MIMO technology to deliver higher bandwidths, there has been some speculation that pre-N networks would dominate the spectrum designated for 802.11 communications, even though the draft specification specifically requires so-called mixed mode operation. While it's certainly reassuring to know that Linksys has been working with multiple vendors to ensure that current WiFi gear will perform at "peak levels" in the presence of 802.11n signals, the real test will come when we start seeing actual real-world deployment of these speedy new networks.
