Outdoor 2G/3G and GPS

Hi I'd like to build a device (with some packaging) that needs to include GPS and 2G, 3G or 4G connectivity. Preferably with built in antennas. It also needs to be able to operate outdoors in a temperature range from -25 to +25 degrees Celsius. It also need to have it's own power (battery)

Do anyone have any suggestions on what to buy as a start?
