Requirement to reduce Latency on 3G Interface
$30-250 USD
Maksettu toimituksen yhteydessä
I currently have an embedded system running on RALink MIP's.
A Mini PCIe Cellular module connected via USB to the main board is acting as the WAN Link.
The system is running OpenWRT.
I have the device connected to the internet, however there is a strange problem which does not seem to happen on other routers:
Ping the WAN IP with 32 Bytes response time is about 500ms.
Ping the WAN IP with >500 Bytes, response time is about 120ms.
I have been told this problem is caused by a mixture of NAT/Firewall but no details were provided so its just a guess as far as i am concerned.
I need this problem sorted, so looking for someone with experience in cellular systems / modems and perhaps also openWRT on Embedded systems.
Please apply asap. Scope for other work for good engineers.
I have attached a screenshot of the problem as a customer would see it.
