Google has been assisting me search for an internet solution to our data and international voice communications we will use on Waiouru.
In a previously post I described how we have purchase a high gain external aerial to be fitted to the roof of Waiouru. This means our modem must have an external aerial socket. The MiFi looks a good option but it doesn’t have the external socket. Searching around I found this site <clicky> which provides a comparison of the various dongles. From this I have selected the Huawei E122. It has the external aerial socket and a reasonable speed (7.2 Mbps down and 2.0 Mbps up). It’s also dual band. One can be purchased from ‘3’ which from what I’ve been reading generally provides the best coverage.
I don’t particularly want to plug the Huawei E122 into the laptop or the netbook as it will mean one of them will always need to be tethered to the dongle, which in turn is tethered to the aerial cable. It would be preferable that the dongle connected into a wired or wireless LAN. That way all the machines can access the network from anywhere in the boat. I’m specifically thinking of the laptop, netbook, iTouch, printer, eBook, Network Media Tank, etc). Going down the wireless trail will give greater opportunity for expanding the network.
I’ve stumbled across the following device, <clicky> from Solwise. It’s a small wireless router which will accept a usb dongle. I’ve checked their website and the Huawei E122 is compatible. The website mentions it operates on 240v AC but also mentions 5-12v DC so I’ve written to them asking if the router can be powered by 12v DC. The device has a 2nd USB port and can take a webcam. I’m thinking it might be possible to link the security module on the Empirbus system to the webcam and the wireless router so the security module could waken the webcam and send a live feed via the router and usb dongle to a mobile phone.
Early days and only an idea!
