[Afonso]’s 77-12 months-historical grandmother lives in a fine looking remote place, with most effective AM/FM radio reception and an occasionally failing landline connecting her to the rest of the area. the nearest 3G telephone tower is seven kilometers away and unreachable with a cellular telephone. however [Afonso] become determined to get her up and running with video chats to far away family. The answer to hook granny into the global hive intellect? build a customized antenna to reach the tower and bridge it over to native WiFi the usage of a Raspberry Pi.
the 1st step within the plan was to be sure that the 3G lengthy-shot worked, so [Afonso] prototyped a fancy antenna, linked above, and hacked on a connector to healthy it to a Huawei CRC-9 radio modem. This acquired him a working statistics connection, and it sends a decent 4-6 Mbps, satisfactory to warrant investing in some greater equipment later. Proof of thought, correct?
On the bridging entrance, he literally burned via a WR703N router before slapping a Raspberry Pi into a water-resistant field with all the quite a lot of radios. The rest changed into a count number of configuration info, getting iptables to ahead the 3G radio’s PPP payloads over to the WiFi, and so forth. Of course, he wants to remotely administer the container for her, so he left a permanent SSH backdoor open for administration. Others of you working faraway Raspberry Pis should still investigate this out.
We feel it’s fabulous when hackers take connectivity into their own arms. We’ve seen many similar feats with WiFi, and indeed [Afonso] had prior to now long gone down that route with a phased array of 24 dBi dishes. within the end, the relatively basic 3G Pi-and-Yagi combo received out.
part two of the task, teaching his grandmother to use an Android telephone, is already underway. [Afonso] experiences that after running for 2 weeks, she already has an Instagram account. We call that successful!
3G connected Hotspot Hangs Out At Your house
[Drug123] made the most out of this inconspicuous gray field on the gable end of his father’s domestic. It serves up a 3G information superhighway connection that become in any other case unavailable..
The venture theory changed into sparked by the absence of wired or fiber optic broadband in the group the place his dad lives. He knew some neighbors were the use of 3G connections, however he couldn’t get it to work internal the apartment. So he set about developing an exterior setting up that would both talk with the cellular network, and supply a WiFi connect to it. Hardware for that is comparatively costly; a USB 3G modem and a WiFi router with a USB port.
The container itself is made from plastic, but even without the Faraday cage effect that would have been fashioned by using a metallic housing, the 3G modem’s internal antenna simply doesn’t do the job. you can see that [Drug123’s] answer became an exterior antenna which is set up on the peak of the roofline. inside the box there’s an exhaust fan to chill issues off once they get too hot, as well as some power resistors which supply a heat supply on the coldest nights. The budget friendly build definitely matches the invoice, and it’s not too hard on the eyes either.
