Nomadic communities have existed for centuries. In fact, early humans were predominantly nomadic before they settled into an agrarian lifestyle. Agreed we have come a long way from our early ancestors, but some people prefer to live a nomadic lifestyle even today.
People with nomadic tendencies like moving around from place to place and prefer not to be bogged down in one place for too long. Clearly, transport is key to this kind of lifestyle since it involves a lot of moving. Things like caravans and portable homes come to mind.
Technology has made it so easy today to live life on the move. Even if you're practically living in a transportation pod, it is possible to work remotely. All other modern facilities like Satellite TV, internet etc. are highly portable now and can be accessed from anywhere.
Just being on the move constantly does not mean you're nomadic though. Truck drivers might drive a lot, but that doesn't necessarily make them nomadic. A nomad moves his or her entire establishment from place to place, and doesn't just travel on account of their job or work.
Many families move around the world without any definite itinerary. Many believe that this provides their children with a kind of valuable worldly education and allows them to explore the world and be truly free.
