I'm interested in knowing... What killer applications do you feel will cause the sales of wireless LANs to take off?

Let’s be honest here. The number one “killer app” is email and number two is internet browsing. When everyday consumers realize they can sit in their living room with a cheap laptop and email or surf then wireless will take off.

One killer app could be voice over IP.

Imagine having a dual mode cell phone that makes calls using *free* VoIP when in a hotspot. A large portion of cell phone calls are made in malls, corporate buildings, restaurants, and hotels. VoIP could be used as long as no handoff is needed, i.e., when driving down I-77.

VoIP is a serious threat to all major cell phone operators. That's a killer application, which also explains why almost all major cell phone operators are getting back into the ISP market by offering WLAN services.

I remember reading in one analyst report ... and I agree ...

"high-speed wireless internet access IS the killer app" ... who cares about taking pictures with your cell phone. let's use WLAN technology to do mobile video conferencing.

As I See all this:
WLAN's killer app. will be the first one to become a standard.
I mean, we have a lot of applicattions and all they're marvellous for all of us, but, what kind of people are we? I mean if we're writing on this forum and waisting our time in wireless applicattions we can to get a lot of big Ideas to do. But the "normal" people ( i mean those who doesn't understand what are that guys doing with a laptop on the park) won't be able to see a "Big Idea" just like us.
We must give them something and tell them what to do with it. On the cell phones it was easy 'cause all the people have been using the wired phones for a lot of years, but how do you explain someone that the voIp is better than the Cell phone?
It all begins just giving them things that they know, they know Internet, just give them a wireless internet, but don't talk them about nodes antennas and wi-fi compilant devices (what the hell is that??)

I think having an 802.11 interface to an "intelligent-server based" memory stick with the ability to recieve files from a wi fi transmitter is a good idea.

There are plenty of applications already available over the internet. WISP's that are banking on some new capability as the driver for WiFi are going to be disappointed. The user that needs this service enough to pay for it is more than likely to be relatively experienced, which means they already have access to the internet capabilities that they need.

Who needs another email or ISP? Don't we already have bookmarks for our favorite financial, travel, news or sports site? The winner will be the first to provide sufficient coverage (i.e. hotspots) in the right locations (airports, conference centers) with the ability to reach the target audience with low acquisition costs.

It's indeed straightforward - email and internet access.

Vocera ROCKS !

They came out a couple of months ago and did a demo for us. It's a sweet project. We kidded them the whole time about how they need to come out with the Star Trek communicator shaped model, unfortunately they want to be taken seriously thus probably won't be doing that anytime soon.

They do have client software that has been tested on PPC's but probably won't be released until next some time. The whole PBX integration is really really sweet, to be able to have calls FWD and transferred back and forth is nice. You can also do conferencing via the PBX.

Another really nice feature you don't pick up from the videos is that the hardware piece is not hardcoded, you walk into work turn it on and log into it. Everything is software based so you're profile will follow you to whatever communicator you pick up. No need to by 300 communicator, you would however need 300 licenses. Nice though in hospotals and retail where you have different shifts of people.

There is also an LCD display for connectivity strength and status and you can send text messages to them. There is also a call-in software piece, meaning you could setup a number to call in on which would bring you to the vocera menu with which you can then contact someone on thier communicator. Uses a standard size headset jack if you don't feel like including the world into your conversations. There is also an SMTP service, as long as you have email addresses and names configured in your profile you could record a message (which would be saved as a .wav file on the server) then have it emailed, right from the communicator.

Roaming is supposed to work pretty well, difficult to demo, and there is also a timeout period you can set. So if you know you have a hole in coverage you can set the timeout to be 10 seconds to give you enough time to get from one coverage area to another without dropping your call. This is also helpful for those little hiccups in connectivity so your not constantly dropping. Future-wise they are also working on text to speech stuff so that you can request database info. and have the software read it back to you, ex. Price Check on SKU xxxx. Can't wait to get our infrastructure up so I can start lobbying for it.

This also looks like it could be worthwhile http://research.microsoft.com/~jiangli/portrait/ too

I am thinking of about letting everyone to able to get access to internet almost everywhere (reasonable places like airports, hotels, campus, malls). In that case, one internet device can be
used both as notebook, phone and verything at a reasonable
cost, which would be much cheaper than 3G I imagine?
You know any products existing allowing that? (not sounds
that difficult technically)

For me the killer of WLAN applications are new viruses. Yesterday I had many problems with my wireless networks. The virus are sending very small packets to all the network. The intention of thar virueses is find back doors for windows xx. they send my wireless network to 1500 ms ping time, 30% packet losses and associations problems.

Please take care with viruses and educate to your users to use antivirus upgrades and personal firewalls! The virus and spamers are killing all the bandwidth in the planet.

Sorry to read and respond so late to the post. In any case, I just completed a site survey for a SAM's Club where the Avaya VoIP phone would be implemented at a later date by another third party, enabling the store management to walk around with a VoIP phone throughout the store and parking lot and stay connected. This, I believe is going to take off for the larger warehouses. In regards to the main post, requesting input to what will truly bring WLANs to the forefront....Roaming Agreements whithin ALL WISPs. Sure, T-Mobile has the largest footprint but if a T-Mobile user wants to surf at a non-T-Mobile site (Wayport, etc) then he/she must set up a separate acct at the other WISP, which pisses a lot of people off at a $30/month fee. There needs to be one entity to manage & set up this relationship because it is obvious that the egos of the larger WISP (T-Mobile) will prohibit any true advancement in this area...Just my .02. Now, will someone please give me a job...lol.

Sure VoIP will be good, but not "free". Just as all of these so called "public" hot spots are not free. Soemone is paying for the bandwidth somewhere and likewize someone will have to pay for the telco interconnect on the VoIP calls. Now if you are only calling others with Voip phones or only calling computers, then the charge isn't there. It's like the cell phone companies and calling mobile to mobile on the same network. It essinetially costs them nothing to do this since there is no interconnect charge. Or like using the Voice feature of the IM systems. No cost except what you pay for the boradband. Anyway, nothing is "free". People may give away service, but I garantee that they are getting something for it. If a mall has a free hotspot, don't you think that people who would use it are also patronizing the stores or at least the food court?

Voice over IP over wireless networks is bad. You have to think if you are connected with a hot spot that you don't know what kind of link is using, maybe is dsl, cable, satellite, etc.

Hot spots are growing very fast, so in few months you will have interference of 10 hot spots more, if you are using 802.11b, you only have 11 channels. We know that 802.11b is using dsss and it avoids interference, but 2.4ghz spectrum is very, very busy. Microwaves oven, cordless phones, electostatic paint ovens, Direct TV, Sky and XM Radio and other more are causing armonic interference, if you want to make a test, try to use your laptop with 802.11b/g near your directv dish.

Voice over IP is very sencitive, if you have many difference between packets (jitter) the protocol RTP that uses H323 or SIP, can't assamble correct the voice packets, if you make a continus test with linux ping xxx.xxx.xxx.xxx -A you will see many differences between packets like 20ms, 50ms, 100ms, 20ms again .... so the voice is not correct. Also you will experiment many packet losses deppending your 802.11x device. If you use a generic card or if you have people walking near your antenna you will have some packet losses.

Other problem with 802.11b is half-duplex CDMA/CA so it say that you can't transmit and receive at the same time. Imagine cisco recomends that use a 10/100 switch full-duplex to enable voice over IP.

Finally if your hot spot uses a generic brand access point and it doesn't have packet priority(QoS), you will fighting with your neightboard HTML web pages and Ftp downloads.

802.11b and voice is good to small offices, but not for hot spots

Voip is Ok with DSL because it uses ATM data link protocol, ATM has very small delay and jitter. Dedicated links are perfect to enable voice over IP.

People hate echo, delay and voice cuts.

By "good" I only meant that if it worked it would be good. I am by no means an expert on VoIP technology and I'm sure there must be many difficulties with implementing it over 802.11 especially in the 2.4 band. By the way 11 channels could not be used simultaneously. The overlapping portions would still cause too much interference to make a reliable link. Youd have to go with only the non-overlapping channels.

I'd say that wireless Voice over IP on public networks is bad. In an enterprise setting it is going to be killer. I see it being a more useful application of wireless ethernet than conventional computer use.

Using wireless ip phones in a public setting isn't going to happen for a long, long time. maybe if theres a unified national network in place, but even then it is going to suffer.

Jim, you mentioned in your tutorial that you are working with the BAA to design a WLAN infrastructure. Your mention of lower bandwidth bar code apps leads me to believe that this will be a common use infrastructure for public and tenant access. My big question......I'm always harping on this one: Will there be outdoor access in aircraft parking areas??

Thanks,
Andy

I am thinking about designing a 802.11 to play music without the need of a laptop or pda. I am talking about a dedicated Wi-Fi Jukebox

The WI-FI Jukebox would show a list of stations gathered from the Internet if you have access to it and optionally if you have a MP3 library in a file server then it would play from your library.

Let me know if you think this is a killer app

Regards,
;)

This is what needs to happen, Take the Palm Tungsten C, add a webcam module, add a headset and have MSN Messenger with Video Chat Application on there.

There you go, there is your web, comm and email solution that everyone wants. This is it.

Tungsten C already has:
1 Headset input
2 WIFI
3 there is the Veo Camera for palm
4 All is needed is a Programmer to make the app and tie it all together..

And the funny thing is, it can be here real soon....

If all you want to pull together and make one, my email address is on my site .. maybe we can make some $$

Residential client/server networks. The gaming console market is going to bring 180 GB + hard drives into houses. Eventually, these could turn into a wireless network server (or at least show alot of people they need massive storage) for PDA's, laptops, cell phones and other smart devices.

Wired home networks have never taken off for many reasons, one of them is they are hard for the average user to set up. Another is it is expensive to have someone set one up. WLAN's does away with both of these.

Now if we just had better security...

The killer app is local public wireless communities.

When you have an internet connection on a wire via DSL or in your hotel, you have no clue where anyone is located.

However if your laptop is connected to the AP near gate 65 at JFK Airport, there's a good sense of exactly where you are located. Now localized information can be pushed to the user. Other users in that general area can communicate directly with each other or maybe even meet in person very easily.

Localized bullitin boards can be set up (say you're looking for a ride share partner from the Huntington NY rail road station). One can drop a note on a local WLAN, where other locals can pick it up later and act on it.

Automated mechanisms in your machines that have preferences configured can automatically query other user's who are logged onto the same local AP farm and hook people up. Looking for a chess partner in the park? Bingo! If these dating services get hold of this concept, all of thier members can have a profile that can automatically match users from the same service as they happen to pass each other in the air.

Putting people who have similar interests together. That's the killer app.
