Hey peeps,
I got other question..... I'm hoping to get a laptop next month sometimes... If I'm using wireless internet, will webcam work, when I hook webcam up with laptop that have wireless... So it doesn't need phone line or cable to make webcam work, for example if I'm at capitol, I want to chat with friends using camfrog or yahoo webcam, not VRS to communcation if I get too bored and my dad busy.... I hope my question is clear enuff...
Here's the straight dope:
Are you asking to use the "wireless" almost anywhere, or are you talking about going to places where they provide wireless internet access like coffee shops or if the capitol provides wifi access? Those are two VASTLY different issues here, and you need to talk to us to give us more information.
1) Wireless "almost anywhere" means having an
aircard or something that uses cellular signal. Very slow, costly, you pay per month and per minute or per megabyte of data -- the only thing positive about it is that you should expect to have coverage anywhere you get a cell signal. SHOULD. Not guaranteed. Service isn't fast enough for video cameras, in my opinion.
2) Wireless cards, or "wifi" where you have a 802.11a/b/g/whatever card you put into your laptop that connects to a local wireless network. Sometimes those networks are free (maybe the capitol provides free wifi to staff), others you have to pay an access fee for a limited time (the hotels I stay at charge $9.95 a night) others you can subscribe to (T-Mobile HotSpot in places like Starbucks charges $11.95 a month or something). It's NOT EVERYWHERE service -- you have to be within 10 to 30 meters of a signal, usually within a building, for it to work. However, the service is usually much cheaper overall and much faster.
We have to assume that your
wireless connection is reliable i.e., you're using an 802.11a/b/g/whatever connection and your wireless signal is
strong enough and
stable enough to transmit without packet errors; make sure your signal isn't cutting out or dropping or otherwise unreliable: that will screw up any video connection you attempt to make.
If that's the case, then you have to make sure that the firewall on the wireless connection does NOT BLOCK H.323 video (ports 1720 TCP, 15328-15333 TCP and UDP, and 389 TCP and other requirements as necessary for your program, camfrog may be different).
The firewall may only be between the wireless connection and the rest of the internet. It may be possible, for example, for you to video chat with anyone in the same building or another person with a wireless card to the SAME wireless network. But it may not be possible to video chat if the firewalls between you and the person you want to chat with are up.
To give a better example:
Let's say you are in a internet coffee shop. Most of them are pretty open, allow anything to go, at the expense that you may be open to viruses and other port vulnerabilities. There's a VERY GOOD chance you can video to another friend who is at home and has their VP set up to receive calls.
Now let's say you're at the Capitol. Let's say the Capitol has a private wireless network for legislators and their staff (does it? Can you find out? Can you set one up?). You have access to it. You connect to it on your laptop. The tech staff that run that wireless network have a firewall to prevent any unauthorized sniffing on congressmen and staff computers. Therefore, the only thing you can do on that wireless network is send email and surf the 'net. No video, no games, no FTP, nothing. MAYBE.
Best thing to do? Tell us what networks you're planning on accessing. If any of them are secure or protected, chances are you'll need to contact their tech people and find out if you can get an exception for video conferencing. Tell them it's for accessibility because you communicate via sign language.
What I do? I have a home wireless network. I go to Panera Bread Company (free wifi if you buy something from their menu). St. Louis has free municipal wifi all over downtown -- you can be pretty much anywhere and still get a signal. I use wifi (#2 of what I listed above) not cellular / aircard (#1 listed above)
Everyone else in this thread was giving you bad information -- misleading info, LAN vs WAN vs aircard, AMD64 (that's a operating system processor, not a wireless device!).
Ha Ha Jk :P ... I don't really care of what you dislike that product of compaq.. You knew it that Hp and Compaq are same production.
.... I really feeling more comfort and truly happy with compaq laptop without being regrets the decision I made.... I have no problem with compaq for about 2 or 3 months. Compaq's very improvement system and programs.. Trust me!
