Ok, here's my situation. I'm running a Verizon/Novatel USB-727 EVDO data modem.
My gear is:
USB-727
CradlePoint MBR1000 Router
Omni external antenna - antenna gain 5dbi, system gain 10-15 db
Linksys PAP2T - VOIP Adapter
Modem readings from the router:
My dbm without external antenna: -85dbm
dbm with external antenna: -75dbm (nice improvement)
Signal Strength with antenna peaks at 73% (would like to see better)
Data speeds:
Download: 700-1500kps
Upload: 200-700kps
Ping times: 90-200 - maxes at times to 325
Now, to the point. With all of this, my intention is to improve my VOIP(internet phone) performance. My problem is sometimes echo and sometimes too much jitter (breaking up of voice).
My first experience was a system called Magic Jack. Some of you might have heard of this - A USB device. The echo and jitter was horrible. I returned it.
My current setup is the Linksys PAP2T using Callcentric as my service. The improvement by changing this setup only has been very positive. However, there is still periodic jitter, and bad weather doesn't help. I myself can handle momentary jitter now and then, but I'm married, and the little woman is impatient, and if she hears just one breakup it's done and buried. I guess some of you guys know the feeling. Your greatest test of salesmanship is convincing your wife.
I'm really feeling I'm on to something here, and just a little tweaking can get me just right. I live in the mountains, and although I do have a direct line of sight to the towers (about 5-7 miles) , the leaves will be coming in soon, obstructing that view, and potentially dropping my performance.
So, the question is - will an amplifier like the Cyfre CA-819 make a difference breaking through the various obstructions (trees, leaves) and improve my performance, momentary jitter, and ping times? If not, are there any suggestions?
