Emergency Cell Network

[River Song]

I was interested to see that Vodaphone/Telecoms Sans Frontiere
has deployed a portable Cellphone network contained in four suitcases weighing 100kg

I would be fascinated to learn what this comprises and how much!!

Would be nice to have when STF

Allons-y

is this what your on about? http://www.gizmodo.co.uk/2013/11/pop-up-...-rescuers/
it says Enclosed within a military standard rugged hard-shell case are all of the components required to facilitate a private GSM network. The Rapid Deployment Unit (RDU) has the means to transmit and receive calls over GSM by utilising an integrated GSM Base Transceiver Station (BTS). This works in conjunction with the Private Mobile eXchange (PMX) software platform that contains the individual software components that would normally make up a macro mobile voice/SMS network – a Base Station Controller (BSC) and Mobile Switching Centre (MSC), which incorporates an SMS switching centre.

I've seen something like this before where the villagers have a local exchange which their cellphones link to and they an call anyone on their local network.

Basically reusing existing cheap technology. phones are thrown away nowadays when someone wants o change their colour scheme. It is the base station that is the expense here.

Midnitemo - not all SHTF situations are total.

Take the current situation in the Philippines. For certain parts the S really has HTF. But other parts of the islands, and indeed the rest of the world, are still up and running. Communications would be useful.

[Lightspeed]

It appears to be local network with secure access ( not general access) and is designed for inter agency communications.

I assume that any mobile telephone number can be given access to the network on the ground.

Its also using Satellite technology to provide voice and video connections to the outside world.

Here's a link to a presentation about the system: http://www.tsfi.org/en/presentation/tech...techniques

RS I think this is what you're looking for:-

Size of a shoe box, 50 watt power consumption, up to 20km range, uses "normal" GSM mobile phones. Free calls between private subscribed mobiles etc

RS I think you'll find in the areas of the Philippines which were flattened ALL communications are OUT, certainly immediately after the storm, phones wont do them any good.

Quoting the link:

"After the Haiti earthquake, we sent a system that was installed at the main hospital in Port Au Prince. They had it working an hour after unpacking it from the box. The hospital PBX was down. They used it as their phone system for about two weeks."

So quite a good system, and at 50w it could be powered by quite a modest PV panel.

The units I am familiar with stacked a pair of ICOM 25 watt UHF mobile radios with a simple diplexer and controller, which was assembled in weatherproof and shock resistant mountings in a Pelican crate, with four Siemens SM20 solar panels and a pair of Hawker Energy SBS30 batteries and a simple 1/4 wave ground plane antenna with roof tripod and 3 metre telescoping mast. These crates weighed about 30kg, including batteries and could be set up on a building roof or any high location in under 30 minutes. This is the same equipment used for putting out portable repeaters for search & rescue or wildland fire fighting purposes. With the solar panels for battery charging these will run for about a year with no maintenance as long as they aren't struck by lightning.

The portable repeaters are coordinated on the "Shared, Non-Protected Pair" or SNP channel, using a continuous tone controlled squelch system to prevent interference from nearby units. The access tone would be determined based upon a regional plan, and the handheld radios distributed to volunteer aid workers would have the SNP programmed in with the several tone options needed for the repeaters in their area of operations. It was also possible to "link" repeaters info a local area network, and they could be used either for voice or data operations.

Generally data operations would be conducted on UHF with horizontal polarization using TCP/IP transmissions at 9600 baud, and voice operations would be vertically polarized using VHF-FM. UHF and VHF repeaters were typically co-located so that shelter logging and medical logistics traffic could be keyboarded over the air while getting simultaneous voice confirmation of the traffic. This also permitted simple voice queries as to personnel and resource status.

While channel allocations in the Land Mobile Radio Services are commonly used for Red Cross, Salvation Army, and other NGO's, amateur radio has the same capablities and many rural localities use "ham" radio operators and equipment to provide similar service. In some parts of the US groups such as REACT provide emergency communications using the UHF General Mobile Radio Service, the VHF Multi-Use Radio Service or the 27 Mhz Citizens Band radios.
