Hi, not sure if I have the best place to ask but I am a student and currently working on a project and I need to be able to transmit video wireless to a smartphone. We are currently just testing this with Apple devices and we have an App that we have already written and confirmed working using out of the box video transmitting hardware but we need to now design our own hardware and reduce the size of the components to as small and compact as possible.

Ideally for the finished project we need to be able to have 2 x 180deg wide angle camera, transmit a signal back to the iphone. The thinking is it will advertise a adhoc wireless the iphone connects to and then have both cameras output displayed on the phone. The power source, cameras and video transmitter has been fairly straight forward but what and how do we go about getting this transmitted over a specific wireless SSID or is there any better/alternative way of getting this displayed onto a smartphone?

Here is a pre-built device that can transmit SDI and HDMI video sources:

Constructing a simple TV transmitter then using a TV tuner app might be better for you if you want to keep it as simple as possible. Google 'TV transmitters' and compare the frequency to the TV channel frequency list. If you are allowed to use pre-constructed modules, you might consider the raspberry pi, arduino or other microcontroller platforms that have the capability to transmit video over wifi. You might also consider software-defined radio. Without knowing your budget constraints or skill level, it is difficult to guide you in the direction you want to go. I hope this helps.
