Mike lives in a remote area and he usually accesses the Internet via his mobile phone. He also has point-to-point internet, which is not only expensive, but he's concerned with security because the service requires a router connection in bridge mode with DHCP. Leo says that routers can be secure as long as he connects with encryption via WPA2. Routers are essentially dumb boxes that can protect him from attacks. But that depends on how they handle their security. It can be just as secure as his home network, or it can be wide open.
Steve has a cabin in the woods, but he has no TV or internet access due to living in a remote area. What are his options? Leo says that wireless internet is Steve's only real option. He has two alternatives - satellite or 4G/LTE. He can check out WISPs or Wireless Internet Service Providers, but the problem with all of these are: 1) they're expensive, 2) they have bandwidth caps, and 3) they require specialized equipment.
Chip wants to know about the possibility of getting internet access via light. Leo says it's in the labs, but it's far from being in prime time. There are some microwave ISPs, which provide service via WISP (wireless internet service provider). There is a long distance Wi-Fi: Clearwire was one that used WiMax, but it died out.
