HP Prime Pro vs standard

[cyrille de brébisson]

Hello,

> the wireless dongles I can purchase 2 of those separately, but this would require the transmitter too correct?

The hardware in the dongle (orange plug in for the calculator) and the antena ("transmiter" that plugs in the PC) are exactly the same.
So, if you have 2 Prime, you can purchase 3 dongles and connect one of the dongle to the PC through a USB A to USB Micro adaptor and it will work.



>I thought that the G2 model already had wireless capabilities built into it, so I thought that it would be able to connect directly to a wifi network.

Nope, the G2 does NOT have build in wifi. Furthemore, as explained bellow, the Prime wireless system is NOT compatible with 802.11 WiFi. So you can not connect to your wifi network with them.


>So, sadly, the HP decision to not work on WiFi was probably the right one. For their goals.

For a number of reasons. Power consumption, in school security, complexity of implementation (WiFi requires full TCP/IP stack!)...
But one of the main reason is that most networks in schools are so protected that you can not connect to them unless you have been authorized by the school IT group. And they would not have allowed kids to just walk in with gazzilions of devices to add to the system... So, our "plug and play" system ends up: 1) working: 2) be much simpler to use than the TI system (for example), which is WiFi based...
