OFDMOFDM
Orthogonal Frequency Division Multiplexing
Allows to transfer more than other forms of multiplexing (Time, Frequency, Code, etc.)
Simplifies the design of the transmitter and the receiver.
Allows for almost the entire frequency band.No gaps to prevent interference needed.
Currently used in WiMax (802.16) and WiFi (802.11a/g).
MIMOMIMO
It uses signal multiplexing between multiple transmitting antennas (space multiplex) and time or frequency.
It is well suited to OFDM, as it is possible to process independent time symbols as soon as the OFDM waveform is correctly designed for the channel.
This aspect of OFDM greatly simplifies processing. the signal transmitted by m antennas is received by n antennas.
In principle, MIMO is more efficient when many multiple path signals are received.
SMART ANTENNASSMART ANTENNAS
Beam Radio signals at a user to follow the user as they move.
Allow the same frequency to be used for other users without worry for interference.
Can’t keep up with the transmission speeds while the device is moving fast (i.e. in a car)
Only 32Mb/s at 62mph (vs. 100Mb/s)
Seamless handoff between towers/access points.
One transmit antenna, two receive antennasAllows connection to two access points at once
MOBILE IPV6MOBILE IPV6
More addresses than the current version of IP Protocol (IPv4) each device can have its own IP Keep IP address even if you change your access
point. Presently translate IP with each change because
of the shortage of IP addresses.
IP Core-everything can talk to each other if they speak the same “language” (Protocol).
