Protocolo IEEE 802.15 - SASE
Protocolo ieee Sergio Scaglia SASE 2012 - Agosto 2012 ieee standard Agenda Physical Layer for Wireless Overview MAC Layer for Wireless - Overview ieee Protocol Overview Hardware implementation specs 2 Sergio Scaglia FIUBA - NXP Semiconductors USA Physical Layer Communication Fundamentals over Wireless Channels Introduction Electromagnetic waves propagate in free space between a transmitter and a receiver (transceivers). Wireless channels are an unguided medium (in contrast with wired channels, where signals are propagated through the wire). 3 Sergio Scaglia FIUBA - NXP Semiconductors USA Physical Layer Communication Fundamentals over Wireless Channels Frequency Allocation In RF-based systems, the carrier frequency determines the propagation characteristics (for example, obstacles penetration). 4 Sergio Scaglia FIUBA - NXP Semiconductors USA Physical Layer Communication Fundamentals over Wireless Channels Frequency Band Since a single frequency (carrier) does not provide communication capacity, a Frequency Band is assigned.
