Thanks for explaining pertinent technology in layman's terms so often in your newsletter and cruise talks Dick. Portions of your good article about the Utah Conference were of great interest. Hopefully you might expand on the technology and capabilities you used in a separate future article. By the way, I was pleased to have met you last November on the funtastic and enlightening RootsMagic Cruise.

I understood you to say that you ran three notebooks with different operating systems on a single network which was created at the conference?? How can you do that? Does each notebook have a separate modem-device to access web? Could all three notebooks have web access simultaneously? How did you make this work? A separate question: Can one you/do you use Skype on such an adhoc network or a single notebook when you travel? Or is there no benefit? I'm clueless but curious about Skype's ability to replace my home phone services after seeing Skype mentions in your newsletters.

My own situation lead me to ask these questions. I live modestly in two countries but find with the dollar's devalue I'm living beyond my means and need to economize. I have a little home in Northern Californa and a smaller one in Scotland. Being a bit disabled I work off of laptop computers only which aren't presently networked and able to access the internet simultaneously. The Calif home is in a rural area just off Interstate 5 where Broadband/DSL is non-existent and Dial-up web access drives me mad. The Scotland place is also very rural but broadband service is blissfully available. Neighbors here in California told me Monday that they solved their web speed issue with Verizon Wireless. By Thursday I'd signed for a 30-day trial agreement @ $60/mo for unlimited use. The rep ran some software before sticking a candy-bar sized Verizon USB720 thingy in my notebook's USB port then sent me home to try it out. The internet speed improvement is dramatic!! Apparently the device is very advanced in that it is Rev A over Rev O and Ev-Do over Edge - all of which is Greek to me. He says this particular device won't work in Great Britain though.

I am now wondering if I could reduce my expenses by eliminating both landline phone services (1 Calif and 1 Scotland) and my present Scotland Broadband service and replacing them with two Wireless contracts and Skype? I'm hoping you can enlighten me and lots of other readers. Regardless, many, many thanks! I will post this here but also look for your email to send direct. SM

---> I understood you to say that you ran three notebooks with different operating systems on a single network which was created at the conference?? How can you do that?

The key thing is to create a network. With today's technology, that isn't hard. Once the network is available, it is simple to hook up as many computers to that network as you wish (up to a theoretical maximum of 253 computers with the hardware I selected) and those computers can use any operating system. Today's networks don't care if the connected computers are Windows, Macintosh, Linux or even some other operating system.

I use a Verizon USB720 device (the same as yours) plus some more hardware to provide Internet connectivity to all the computers on the network.

---> Does each notebook have a separate modem-device to access web?

No. Each computer accesses the Web through the network, not via modems. All the computers on the network have full Web access as all of them are sharing the single Verizon USB720.

---> Could all three notebooks have web access simultaneously?

Yes. In fact, it will support a theoretical maximum of 253 simultaneous computers. I think that would be rather slow, however. I'd suggest a maximum of five or ten.

---> How did you make this work?

That functionality is included with most networking software. The NETWORK must have Internet connectivity, then it shares that with all the computers on the network.

I wrote a Plus Edition article about this perhaps a year ago but have since added mode advanced capabilities. I do plan to write about it again but have two more things I wish to add/experiment with first.

---> Can one you/do you use Skype on such an adhoc network or a single notebook when you travel? Or is there no benefit?

I use Skype MORE when I travel than when I am at home. When I am at home, I have a variety of phone services and options to choose from (standard phone, cell phone, etc.). When traveling, I have fewer choices so I use Skype whenever possible as it is the cheapest method.

---> ...but curious about Skype's ability to replace my home phone services after seeing Skype mentions in your newsletters.

I no longer have a standard telephone line and don't ever plan to have one again. I have Skype, MagicJack (which is a lot like Skype) and a cell phone. Actually, I really should get rid of MagicJack as it duplicates Skype but I already paid for it for a year ($20) so there is no benefit to canceling for a while.

For me, the combination of a verizon USB720 plus Skype plus a cell phone gives me more communications capabilities than I need.

HOWEVER, it strikes me that you do not need a network. If you have one computer in California and you already have a Verizon USB720, you already have everything you need to use Skype, except for the Skype software itself and perhaps a handset or headset. The software is free. Headsets and telephone handsets cost ten dollars or so, if you do not already have one. Go to http://www.skype.com for details.

Once you get some experience, return to Scotland and get a similar wireless device from a local carrier there. They are available from several vendors in the U.K. Then do the same in Scotland. You can use the same Skype user name in both places so it effectively means that you are moving your telephone with you. If you obtain SkypeIn or SkypePro (about $3.00 a month), you can have one telephone number assigned and you can answer that number from any location. Your friends could call that number at any time of year and you could always answer it, regardless if you are in California or in Scotland or perhaps traveling someplace else in between.

I have done that from hotel rooms all over the U.S. as well as from Canada, London, Hong Kong, Bombay, and a cruise ship in the middle of the ocean. The process is simple. Again, you do not need to add your own network. You already have most everything you need.

Thanks Dick for answering my questions so very thoroughly. Your explanations removed conceptual blinders! Before reading your explanation, I thought all networked PCs needed to be of the same ilk. I thought Skype only worked on land-line based internet services. I thought one needed a separate router/modem/access-point thingy box plugged to a land line phone service to have a "network."

Plus...given that I have four notebooks (Two stay in Calif; One travels with me; the Fourth stays in Scotland) - Its a gift to learn I can create a Calif network with the one Verizon device AND have a second network in Scotland with a UK data device and service. Who'd_have_thunk??

Is it right to assume that the additional hardware your networked computers needed (and I will need) were USB or PC card network adapters? Anything else?

Other possible article topics some day might be wireless printers, reviews of GPS devices and whether Skype can be used on Smartphones such as Blackberries. Others besides myself are probably very curious about which GPS devices you favor and why. As to printing wirelessly, following my brother's suggestion, I recently spent $99 on a HP7460 wireless printer. It is surprising how delightfully "freeing" it is to print from my laptop while perched on porch, patio or snuggled warmly in a downy-blanketed bed. Yes, the ink is a rip-off but the convenience is pure bliss.

Again, Thank You! SM

---> Is it right to assume that the additional hardware your networked computers needed (and I will need) were USB or PC card network adapters?

In many cases: "Yes." Many of today's laptop computers come from the factory with wireless ("Wi-Fi") adapters built in so that you do not need to insert anything into the USB ports or PCMCIA card slot. Even the $399 tiny, 2-pound laptop I purchased a couple of months ago has built-in wireless (Wi-Fi) networking.

If your laptop does not have built-in Wi-Fi wireless networking, you can easily add it via a USB or PCMCIA card slot adapter. Those adapters cost $20 to $40.


---> Anything else?

No.


---> Other possible article topics some day might be wireless printers...

OK, but all printers can (in effect) be wireless. Hook them up to a wired and wireless router or to a desktop computer that is also connected to a wired and wireless router, then share the printer. ALL the computers on the network can then access the printer, including wired and wireless computers.

I have a network in my home that includes two printers: one laser black-and-white printer and one inkjet color printer. My wireless router also has some computers hard-wired to it in addition to the laptops connected via wireless. (Most of today's wireless routers also have four network connectors on the back for plugging in wired network connections to other computers so it is easy to have a mix of wired and wireless computers.) My two printers are both wired but all my computers can print to them, including Windows, Macintosh and Linux computers, regardless of whether wired or wireless connections are in use. It is simply one network and all computers can (optionally) share all peripherals, including all the printers.


---> reviews of GPS devices and...

I have written several GPS articles in past years, mostly Plus Edition articles. I own too many GPS devices! (smile) Look at http://www.google.com/search?hl=en&domains=blog.eogn.com&q=gps&btnG=Search&sitesearch=blog.eogn.com

---> whether Skype can be used on Smartphones such as Blackberries.

The quick answer is "it all depends..." There are many variables involved. Some Smartphones can work on Skype but most cannot. I will add, however, even on those that theoretically can do it, you probably won't be happy with the results. In short, I wouldn't bother even trying. I may change my mind within 2 or 3 years, however, as the technology continues to improve.

Let's try a "drawing." Depending upon which font your web browser uses, this may or may not look "funny." It is supposed to be a drawing of a typical in-home network with four computers (they can be any mix of Windows, Macintosh and Linux) and three printers. Some computers are connected via wireless, some are hard-wired. One printer is wireless, the other two are wired.

ALL FOUR computers can access the Internet simultaneously and, if configured properly, all four computers can print to any and all three printers.

You can see the "drawing" at http://www.eogn.com/downloads/network.txt

By the way, this is close to being a drawing of the network in my home.
