Wireless Home Entertainment, Part III
September 11, 2002
Show me the wireless home entertainment system of the future before we'll believe it, say analyst. One company, Magis Networks, plans to show them soon.
Home entertainment networking using 802.11 sounds like it can't miss, but according to some of the people we've talked with, it will be a few years before it's a mass-market proposition.
The technology isn't quite ready and key players such as set-top box makers and digital cable and satellite service providers won't be believers until it is. The market, meanwhile, is fragmented.
A surprising number of technically savvy consumers, though still a tiny minority, have started to experiment with home entertainment networking at a fairly primitive level -- using PCs as personal video recorders (PVRs) and streaming MP3s to their stereo systems. For most consumers, though, it's still a vague concept at best.
That pretty much sums up the sober-sided, glass-half-empty perspective on the subject. Now meet San Diego-based Magis Networks.
Magis claims to be, and probably is, the leading maker of 802.11-based chipsets designed to support home entertainment networking. One other contender is ViXS System of Austin, TX.
Magis appears to have a slight lead at this point. Chipsets based on 802.11a and Magis's proprietary Air5 MAC-layer Quality of Service (QoS) technology are almost ready for shipping. (The Air5 technology also supports HiperLAN2 and Wireless 1394 standards.)
"We'll do demos in December and field trials in the first half of next year," says Magis executive vice president Pete Fowler. "Assuming they go well, we'll see commercial deployment in 2003."
The company claims Air5 not only solves 802.11's QoS problems -- ensuring undisrupted transmission of multiple high-bandwidth HDTV signals from room to room in a home -- it also improves 802.11a range and throughput performance. It will deliver 40 Mbps at up to 250 feet, Fowler says.
In addition, Air5 provides beefed-up security in the radio link. Reliable security is crucial for content providers who will want to make sure war drivers can't intercept signals on a home WLAN and steal DVD-quality pay-per-view or video-on-demand movies, Fowler notes.
The performance claims for the Magis technology appear to answer the concerns of rival 802.11 chipset maker Intersil of Irvine CA. Intersil believes 802.11g, with its superior range, will become the preferred standard for home entertainment applications.
The trouble for Intersil is that 802.11g isn't a standard yet, but 802.11a and Air5 are here now. Furthermore, as Fowler points out, 802.11a offers superior capacity in terms of numbers of non-interfering radio channels. This will be important in avoiding interference between WLANs in, say, adjacent apartments.
Intersil vice president of marketing Chris Henningsen and Michael Greeson, senior analyst and director of broadband research at Dallas-based market research and consulting firm Parks Associates, also both told us that set-top box and consumer electronics manufacturers will be inclined to wait for finalized standards before committing wholeheartedly to wireless home entertainment networking technology.
If that's the case, how can we explain Magis's roster of strategic investors? It includes cable TV service providers AOL Time Warner and Charter Communications, set-top box maker Motorola and consumer electronics manufacturers Hitachi, Sanyo and Panasonic (Matsushita Electric Industrial Co. Ltd.)
It's the "whole [home entertainment] food chain," as Fowler notes.
Although he can't or won't reveal product plans, the clear implication is that all of these companies are also, directly or indirectly, Magis customers.Not surprisingly given the state of its technology development, Magis is a good deal more bullish on the home entertainment networking market than anybody else we talked to.
Analysts like Greeson, Fowler argues, have failed to take into account the dynamics of the cable industry. Big service providers have made huge investments in infrastructure to enable new digital services. Now it's logical that they turn their attention to the set-top boxes that will allow them to exploit this new infrastructure.
One key objective for cable and satellite multiple system operators (MSOs), he points out, is to break the set-top box logjam and find ways to increase the amount of revenue they can generate from each subscriber.
Right now, subscribers must have a set-top box on each television in order to bring in digital programming such as cable TV, pay per view and video on demand movies. Many consumers balk at digital cable and satellite services because of the extra expense of multiple set-top boxes.
However, with the Magis technology, it would be possible to install one gateway device that could distribute services -- cable TV, DVD-quality video on demand, CD-quality music, Internet access, etc. -- to TVs, PCs and stereos around the home.
The remote devices would be equipped with relatively inexpensive "thin-client" Air5-based devices -- either built-in or added on -- that would allow them to tune in services and receive signals wirelessly from the gateway device.
In this environment, cable and satellite MSOs can hope to remove consumer objections to their offerings, especially when consumer electronics manufacturers start building in Air5/802.11a thin clients, and also sell more services -- including multiple simultaneous movies, voice-over-WLAN-based telephony and wireless security camera services.
"This is huge for the MSOs, especially at this time in their market development," Fowler argues. "But analysts don't see it. We've got to demonstrate it to them."
While Magis's strategy hinges on the role of MSOs and their suppliers, the set-top box makers, and while it believes the MSOs are more interested and anxious to move on wireless home entertainment networking than analysts like Greeson say they are, the company also sees other more short-term market opportunities.
The first application will probably be point-to-point video. Powerful home computers equipped with TV receivers and MPEG encoders can already function as personal video recorders (PVRs), recording digital content to a hard drive.
With the addition of an Air5-based "dongle" -- some kind of add-on device, perhaps connected to a FireWire (IEEE 1394) port on the PC -- the PC could wirelessly distribute recorded programming to TV sets equipped with Air5 client dongles.
"That kind of thing is about 18 months away," Fowler says. "And you know how quickly [the PC world] can ramp up [with new technologies.]"
Magis also sees corporate applications for its technology -- enabling telephony and video conferencing over office LANs. In fact, it concedes that data, not home entertainment, will dominate the 802.11a market until about 2005.
While corporate and after-market point-to-point video applications will happen first, Fowler believes the MSO-driven home entertainment distribution application will evolve concurrently. By 2006 and 2007, Magis sees home entertainment applications dominating the 802.11a space.
So who's right? Do wireless home entertainment networks start taking off in months or in years? Companies like Magis and ViXS, which has a similar vision and technology, are clearly betting on an earlier rather than a later breakthrough.
Analysts, appropriately, remain skeptical. Show me, they say. Magis intends to do just that.
