h1. Equipment

*- Mechanical equipments*

The first equipment that we had (given by Professor Franck) was a Voyager "suitcase":http://www.pelican.com/ca/fr/product/watertight-protector-hard-cases/medium-case/standard/1520/, of the brand Pelican.

Here is a picture of our suitcase.

The size of the suitcase is : 50.2 x 40.1 x 18.8 cm. Therefore, the suitcase is carriable by a single person. But, the main quality of this suitcase is that it is very robust (it is resistant to a one meter drop, STANAG 4280 and Def Stan 81-41 certification), it is resistant to high and low temperature (-40°C to 99°C, STANAG 4280 certification) and it is waterproof, and therefore dustproof (IP67 and MIL C-4150J certification). 

Therefore, this suitcase cope with our form factor, carriable, resistance and waterproofing constraints.

In order to fix the equipments on the suitcase, we used wooden board as a stand, and plastic collars for fixing the equipments to the stand.

*- Network equipments*

We choose to put a router in our Microbox, to cope with the scalability and security constraints. The chosen router is a "Microtik hEX PoE Lite":http://routerboard.com/RB750UPr2.

Its size is : 113x89x28mm. Therefore, it fits in the suitcase perfectly, and we will have plenty of place for placing other equipments.

This router is that it has a routerOS, so we can monitor the different connected equipment, we can parameter the Wifi network, and also other parameters in order to have a secure connection. It also five 10/100 Ethernet ports (one in, four out), so we can connect to it four equipments, plus the Wifi connectivity. It also has a USB port, which is useful for charging a device. This router is reliable, small and is affordable for our project.

The other network equipment is a VoIP phone, compatible with SIP accounts. Professor Franck supplied the "Grandstream BT 200":http://grandstream.com/products/bt_series/bt20x/bt200.html . Its size are 18x22x6.5 cm.
