Ariane: hey this is cool. looks like devils canyon is nearly ready for guests! Se Jong: lol Justin: sure, ariane, if those guests are just bytes of data too! Justin: K, do you have a web cam? no point in just staring at the no video signal until ed gets here Ariane: where is ed? he just sent me an im Ed: Hey sorry guys, I just came down from the mountaintop. Justin: well that’s not bytes of data then. No way to describe him with just the keyboard keys and ASCII Code Ed: OK, looks like we’re looking at a mix of optical fiber and twisted copper wire. Justin: Yes, the fiber will connect buildings and floors, but the twisted pair will go to the desktop. It isn’t as fast as all fiber, probably 1 gigabit per second, but we won’t need those special interface cards for the fiber connectors. All the computers and other devices already have jacks for the regular twisted pair connectors that look like phone jacks. Se Jong: We’ll need to offer them wifi anyway though, with the wireless routers and lots of access points. Guests will be happy that they can use an Ethernet cable in their rooms – that’s usually faster than wifi. Ed: That makes sense, Se Jong. They’ll probably be downloading movies. It will still use TCP/IP, yes? Se Jong: Yes, and also Internet Protocol Version 6.0 – they all use TCP/IP. Justin: It will work fine for internet access, and be very fast, too. Ed: What about this recommendation about the coaxial cable? Se Jong: Well, we may not need it if we can deliver the TV signals using the fiber and ethernet, but installing it now along with the other wiring is cheap, and would be very expensive later. Justin: Yeah, it’s not that much anyway. This will give us the most options. You never know what those cable companies will do, and with so much competition, we want to have the option available so we can take advantage of price breaks. Ed: OK, sounds good to me. Ed: Let’s look at the wifi now. Se Jong: K, recommended this too. But how can we be sure we’ll have enough access points? Justin: We can always install more wireless access points if we need them. Not a problem. Ed: Good, you know people are using their smartphones with wifi too, so we want them to be able to connect from anywhere. Ed: What about the cell towers? It’s annoying that we have to help pay for these. Why don’t the carriers put them up? Ariane: well they will pay part, and we’ve got to have 3g coverage at least. Justin: really 4g now. Ed: Do we have enough towers do you think? Justin: well I hope so – the engineers thought those placements would give coverage everywhere – even the valleys. Ed: let me show you this design for a cell tower Ed: (smiles) Ariane: is clapping! Justin: ha… the tree looks a little goofy to me, but maybe we can spray it with some fake snow in the winter. Se Jong: A jolly snowman cell tower! Ed: OK, let’s see what we’ve got for landline voice calls. Ariane: who makes voice calls anymore? Se Jong: not me. Justin: ha, not me either, I just text. Ed: Yeah, well I’m old fashioned! Gotta have voice calling capabilities – voice mail, forwarding. Ariane: this seems like a great deal… no PBX on premises. Justin: K may know about some service providers who can handle this. With our smartphones, it is probably ok that the cost per minute is high. Not many will be using their regul
