Yes, I read the posts about it on habré :)
The bottom line is this. In a country house plan to install a rooftop external antenna, and somewhere in the attic Wi-Fi router and 3G modem. The search found only this: "Huawei E960 3G router with wifi" (which, judging by the Internet, totally not available in the variant with connector for external antenna).
Suddenly stumbled upon just such podemchik: gprs-modem.ru/product/3g-modem-teleofis-rx301/
Industrial looks more sensibly to work in a cold attic. However, actually, a question
Does anyone have some experience with modems this company (Teleofis)? Will they make friends with some "domestic" Wi-Fi router with USB on Board (like any D-Link)? And maybe someone has already worked out the options?
Topic connecting an external antenna is very important because there is difficult terrain and very dense buildings. At the same time, the installation of a rooftop antenna will bring it to the BS in line of sight.
To disassemble the USB 3G modem and solder the wiring for the antenna not want. Want more or less "industrial" solution in common :)
Thanks in advance for the answers!
