Author Topic: Wireless Networking Question Adam Fraser Master Film Handler Posts: 499 From: Houghton Lake, MI, USA Registered: Dec 2001 posted 02-26-2007 06:33 PM                        I have two buildings on my property that I would like to both share a satellite internet connection. They are approximately 1000ft. apart and one is approx 20-30 feet higher in elevation. There is one line of tall trees between the two buildings and a christmas tree field w/ 10ft tall trees between the two also. Is this even possible, and what equipment would be needed to accomplish this. Both are fairly new desktops.  |  IP: Logged Jarryd Beard Expert Film Handler Posts: 229 From: Hellertown, PA Registered: Jul 2004 posted 02-26-2007 07:44 PM                     Look into the Super Cantenna. My friend has one of these. It really improved his signal range. I'd imagine some networks he was able to connect to were at least 1/4 mile away. One in each building might be all the better. They are reasonable in price as well, especially when compared to the worthless "high gain" antennas sold by the router companies.  |  IP: Logged Mike Olpin Chop Chop!

Most likely, you want something like this. Also, check out the Proxim product line.  |  IP: Logged Jon Miller Jedi Master Film Handler Posts: 973 From: San Diego, CA, USA Registered: Sep 1999 posted 02-26-2007 08:23 PM                     quote: Jarryd Beard Look into the Super Cantenna. The first thing that came to my mind upon seeing "Cantenna" is an old Heathkit dummy load in a paint can. I'm not a ham, but I remember seeing those things in Heathkit catalogs long ago.  |  IP: Logged Adam Fraser Master Film Handler Posts: 499 From: Houghton Lake, MI, USA Registered: Dec 2001 posted 02-27-2007 10:14 AM                        Im willing to spend several hundered dollars for something that works properly. Thanks for the replies. Maybe up to $400-500.  |  IP: Logged Stephen Furley Film God Posts: 3059 From: Coulsdon, Croydon, England Registered: May 2002 posted 02-27-2007 05:54 PM                     You can also do point to point links with lasers; we've got three pairs of these: web page They're generally pretty reliable, we've been using them for about four or five years now. very dense fog, or sun shining directly into them can cause problems, but most of the time they just work. We've got the 100Mb. ones, but they also make Gigabit ones. They're not in the price range you're looking for though, unless you can find a secondhand pair.  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 03-28-2011 10:24 AM                 It has been 1489 days since the last post.  |  IP: Logged Barry Floyd Phenomenal Film Handler Posts: 1079 From: Lebanon, Tennessee, USA Registered: Mar 2000 posted 03-28-2011 10:24 AM                        I've got a similar situation to Adam's, and I'm not sure what equipment I need to accomplish it. We've got DSL internet service at the theatre, and we're going to start using the internet to process our credit card transactions. Our credit card terminals (First Data FD-100) have an Ethernet port on them so they can be hooked to the network, so the terminals inside the building we have no problem with as it will all be hardwired. Our ticket booth is approximately 300 feet away from the main building, and we have no communication wires going down to the booth from the main building. I've been told I can do it wirelessly, but don't know what equipment I need. There will be no computer in the ticket booth, only the credit card terminal that can be hooked to a network. What do I need on each end to make it work reliably and securely?  |  IP: Logged Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 03-28-2011 11:16 AM                     It sounds like you might need a pair of directional WiFi radios and a network POE (point of entry) device. We have to use this approach with sending data to/from certain LED-based electronic variable message centers. One of the radio models we're using is an EnGenius EOC2611P. It's a "super G" 108Mbps rated model. You can order these from Streakwave Wireless. The range on these radios is really pretty far, up to 6 miles. You should have no trouble jumping 300 feet. The radios include a POE.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 03-28-2011 11:34 AM                        Do you have a telephone in the ticket booth? If the telephone wire has two copper pairs and runs to the main building, you could use the extra pair for a DSL circuit. You can buy two used SDSL (not ADSL) routers on Ebay and set up a DSL circuit between the ticket booth and the building that has the wired connection. This would be easy to set up and more reliable than wireless anything. Alternatively, if you have a telephone in the ticket booth, but the wire goes to the telephone company central office and not your main building, you might be able to get the phone company to sell you an "alarm circuit" that terminates in the ticket booth and main building for a few dollars per month. If the total distance is not too great, you could probably run DSL over that (but that is not guaranteed).  |  IP: Logged Barry Floyd Phenomenal Film Handler Posts: 1079 From: Lebanon, Tennessee, USA Registered: Mar 2000 posted 03-28-2011 11:58 AM                        Scott, we have no telephone lines going down to the ticket booth either, only 2 electrical circuits in a 1 inch buried conduit. My thoughts were to have just the credit card terminal in the ticket booth, plugged into some type of wireless device via RJ45 ethernet cable, then transmit the signal back up to the building wirelessly to some network transceiver that was plugged into the network switch. The Streakwave link that Bobby provided looked like it might do the trick.  |  IP: Logged Adam Martin I'm not even gonna point out the irony. Posts: 3686 From: Dallas, TX Registered: Nov 2000 posted 03-28-2011 03:16 PM                     If you plan on transmitting credit card data wirelessly, make sure you secure your network and encrypt the data.  |  IP: Logged Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 03-28-2011 05:43 PM                     The EnGenius radios will let you encrypt the data. They also allow MAC address filtering.  |  IP: Logged Bradley Peters Film Handler Posts: 4 From: Boissevain, MB, Canada Registered: Dec 2010 posted 03-28-2011 06:00 PM                     If the wireless units can be located inside on both ends then you may not need actual outdoor units. (At 300 feet the long range design typical in the outdoor units is almost certainly more than necessary.) You might be able to use a device designed to connect a set-top box or media player to a home wireless network for example. (With a standard wireless router connected in your main building.) Some examples: TRENDnet TEW-647GA Cisco Linksys WET610N Netgear WNCE2001  |  IP: Logged
