Compare the technologies how does each technology works?
Greentooth is a lot faster more secure and has a bigger range and can be use up to a mile. 8002.15LA
Bluetooth is is slower not as secure and can use within a few meters. 802.15LA

Wifi 8002.11z run a lot faster it is very secure and has a range up to 1 mile.
Wifi 802.11a/b/g/n/q  is a lot slower the security was really good but it is less down by the range and competing signal coming from other router using different channel.


What factors affect the range and speed of wireless technologies?
the range could be affected by wall and how far you are away from the router. other router can affect the signal and equipment that uses radio wave like microwaves can effect proformas.


What is IEEE 802.11?
IEEE 802.11 is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4, 3.6 and 5 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). The base version of the standard IEEE 802.11-2007 has had subsequent amendments. These standards provide the basis for wireless network products using the Wi-Fi brand name.

IEEE 802.11-1997: The WLAN standard was originally 1 Mbit/s and 2 Mbit/s, 2.4 GHz RF and infrared (IR) standard (1997), all the others listed below are Amendments to this standard, except for Recommended Practices 802.11F and 802.11T.

IEEE 802.11a: 54 Mbit/s, 5 GHz standard (1999, shipping products in 2001) 

IEEE 802.11b: Enhancements to 802.11 to support 5.5 and 11 Mbit/s (1999)

The ones in blue are the ones used in the smartphones of the future.

table from http://en.wikipedia.org/wiki/IEEE_802.11#802.11n

What wireless technology did you use for your future smart phone?
the iPhone 9 used the latest wireless technology.
Greentooth runs a lot faster than Bluetooth and it more secure
WI-FI 8002.11z


Do you thing it will eliminate the problems currently associated with wireless networks?
No. There are lot of competing signal and with block the signal coming for your router.


What security measures can you take to ensure your wireless network is secure?
wpa2 is lastest security messer to help you secure you network. this is backward compatable with wep, wpa. have a web brower to access the router.


What are DSSs, FHSS, IR and OFDM and how do they relate to wireless technologies?
DSSS has the advantage of providing higher capacities than FHSS, but it is a very sensitive technology, influenced by many environment factors.The best way to minimize such influences is to use the technology in either point to multipoint, short distances applications.

FHSS is a very robust technology, with little influence from noises, reflections, other radio stations or other environment factors.
