At first my sincere apologies to everyone for the blank accidental post from my work e-mail address/template just about an hour ago. It was not the intention. Thousand apologies!
About 5:30 in the morning and after completing moving to our new place and trying to get organized - my brain and body are not in tune... I clicked on File --> Reply by accident and then tried to click "File --> Close"... instead I hit "File --> Send", while I was quickly going through my mail. Thousand thousand thousand apologies. Been up now for almost 24 hrs. Now it's past 7:00 AM. On updating all of you - I want to touch base with this VoIP Wireless thingy & thanks to all of you who provided suggestions & ideas. I also want to convey my appreciation & thanks to Dave Donavan of Fulcrum Solutions who has generously lent me his wireless equipment which I have installed on the premises. Dave also bent over backwards and came over to drop the equipment knowing my crazy schedules & stress of moving. Thank you Dave! I don't have to camp in empty rooms just for telephone and internet access! I am continuously amazed and touched by the generosity of folks here at the TAUG whether it is sharing information or assisting in other ways. The phenomenon of sharing and receiving more in return in many different ways, is truly magic. The famous saying "the more we give the more we get" has proved its place in this TAUG community. Technical Updates: The equipment used was DWL-810+ (DLink). A directional antenna DWL R60AT attached to DWL-810+ is also being used ( http://support.dlink.com/products/view.asp?productid=DWL%2DR60AT ) and originally meant for indoor usage (though I have one unit mounted outside my current residence). It's range claims to be 1650 feet (502.92) meters. This is more than enough and I am getting a clean signal from my old place to my new place at a clear line of sight. For the size of the antenna, this is quite impressive. I decided to take my laptop out and check the accessibility. The upload and download speed is quite steady. I've confirmed it by trying to download a 10 megabyte file - and the speed at this wireless level is quite steady, reliable and I have to say impressive. As per http://myspeed.visualware.com/voip/ below are my stats: -- Download 2.16 Mega Bits per second (Not Bytes) -- Upload 418 Kilo Bits per second (Not Bytes) ** G.711 is at 64 Kilo Bits per second - so I suppose my upload speed can easily manage my G.711 usage... though I am using G.729 (8 Kbps) or GSM (13 Kbps) ** More details: Speed test statistics --------------------- Download speed: 2168200 bps Upload speed: 418240 bps Quality of service: 50 % Download test type: socket Upload test type: socket Maximum download pause: 175 ms Average download pause: 5 ms Minimum round trip time to server: 87 ms Average round trip time to server: 89 ms VoIP test statistics -------------------- Jitter: you --> server: 4.0 ms Jitter: server --> you: 8.4 ms Packet loss: you --> server: 0.1 % Packet loss: server --> you: 0.0 % Packet discards: 0.0 % Packets out of order: 0.0 % Number of supported VoIP lines: 5 Estimated MOS score: 3.9 At this moment - I have nothing connected to my DSL modem at my old place, except the wireless. It is as if there is a solid wireless link between the two places. So technically I'm 100% wireless at my new place. Being the skeptic... needing to try things out practically to verify a theory - I had to re-attach all my SIP Phones to the non-wireless router that is attached to the DWL-810+ and try the miliwatt test. Then I called several voice mails and started talking to myself (but not answering back) -- and replayed the recorded messages from Asterisk servers. I have nothing else to say except that this is a superb inexpensive solution for those of you who wish to have your own WiFi in your backyard. A packet loss of transmitting Voice Packets at 0.1% in my humble opinion is acceptable. Not that I want to stop this WiFi experiment here... actually it was not an experiment but a necessity which has now evolved into WiFi experiment exercises. I do intend to get that Cantenna Mike suggested and other larger directional antennas that claim range of 5+ Kilometers. Heck for me 1Km is good enough :). Obviously the way things are going, the range of wireless devices is becoming inversely proportional to the cost. All the best and thanks again to everyone! Best, Reza.
