So I'm not sure if this tutorial helps (since I have no modem):
- Optimal Setup for Modem -> Router -> Ooma
But, I did lower my QoS setting from 384 Kbps to 0 as is often suggested. My setup is as follows (where ==> indicates a wired connection & --> indicates a wireless connection):
Internet ==> WISP AP --> My rooftop antenna & radio ==> Linksys WRT54G router & radio --> Ooma Telo ==> Telephone
Note: There is no modem because this is line-of-sight WiFi wireless ISP ... sort of like at a hotel or at Starbucks but expressly designed for wireless ISP to customers that have no access to cable or DSL and for whom satellite and/or cellular is too slow.
I just tested my wireless ISP (WISP) VOIP call quality at http://www.phonepower.com/speedtest as just OK:
- Download = 1.81 Mbps
- Upload = 483 Kbps
- Jitter = 1.1 ms
- Packet loss = 1.0 %
- MOS score = 1.0 My problem is that the voice quality is barely ok. The problem is the other caller drops out for a second or two (various callers) and I drop out (they say) for a second or so intermittently.
In addition, my kids 'sometimes' use the bandwidth watching videos and playing video games.
Given my MOS score:
Q: What advice do you have when there is no modem for how I can improve my Ooma voice quality on WiFi WISP?5 - Perfect. Like face-to-face conversation or radio reception.
4 - Fair. Imperfections can be perceived, but sound still clear. This is (supposedly) the range for cell phones.
3 - Annoying.
2 - Very annoying. Nearly impossible to communicate.
1 - Impossible to communicate
