I found elsewhere: "this is pretty much just 2,000 km2 of sand and rocks", and "consisting mainly of sand and rocks ... 2069 sq km (795 sq mil) and is shaped like a trapezoid."
, and checked it out on satellite. The nearest road appears to be 250km away. Definitely no chance of internet. But even this place I suppose could be made habitable with long term effort. Solar would be a good bet for power, and long distance radio or perhaps microwave or satellite would be viable for internet. Semi-subterranean dwellings could be ideal and even support crops, once constructed. But investment would be significant. I wonder if you could fly in/out hardware, junk and supplies via solar-powered drone?
It's still de facto Egyptian territory, although for the bizarre political reasons outlined in the Wikipedia article they just don't claim it as such. Flying in/out isn't going to work too well since it's fully surrounded by Egypt and Sudan.
From that page: Egypt still administers the territory. That was my point. You could build an underwater city in the middle of the pacific and some government would somehow claim it. If there is money there, a nation will be present to collect its cut and make sure you abide by their law.
