synopsis
Create a low cost communication node (with VoIP as a base), trying to connect as many as possible types of links, for example:
- copper/fibre/WiFi network
- DECT/POTS telephony
- SIP/SCCP
- HAM radio (or preferrably, CB radio: 27MC/PMR)
- copper/WiFi/USB uplink
It also could need some of the following functionality:
- PoE service (to drive phones, remote switches/accesspoints)
- battery supported/powered (in case of power failures/lack of power)
- sturdy compact waterproof casing
So to make the first prototype, I chose the following:
- ammo box
- 7Ah battery
- Fritz!box 7270
- two Raspberry Pis
- Netgear GS110TP (8xPoE + 2xSFP)
- step-down converter 12->5V
- step-up converter 12v->48V
prototyping
Tested the following items:
- Two Raspberry Pis on a drill battery pack (step-down)
- uses 0.33A at approximately 12V
- Cisco CP7940 on a drill battery pack
- uses something between 0.36A and 0.45A at approximately 12V
- Fritz!box has a switching regulator to 5V tested between 5.5V and 15V (drops off at 5.3V idle and elca at power supply segment is rated 16V)
- without WiFi, it peaks at 0.44A (12V), and idles at about 0.34A-0.38, which the webservice is saying 41%-43%, which means it would top at about 0.88A.
- With 15V power it idles at about 0.25A
Still to test/measure/fix:
- battery, initially 7Ah (ordered)
- PoE switch at 48v (ordered)
- whole set with battery and battery charger
- Fritz!Box router (NAT, FxS, FxO, DECT)
- Raspberry Pi running FreeSWITCH and DHCP
- Raspberry Pi running FreeSWITCH and TFTP
- (PoE) ethernet switch (ordered)
- Efficient power converter(s)
