Do you care about the power consumption factor or not ? if not... then Wi-Fi may offer a high rate ( N standard and beyond).
Dear Ihab,
Kindly guide me if i have to choose a wireless communication module with power consumption factor in mind.
what module i should prefer then.
The most common wireless communication system for shortrange communication and high speed is the WI FI standard. It is rate and power adaptive since it uses adaptive ofdm modulation technology where very subcarrier can be modulated with an m order QAM with m is the number of constellation points in the QAM symbols. At the highest range one uses 4 QAM and as the range decreases the QAM order increases and consequently the dta rate increases. So,in principle the highest rates are achieved at the smallest distances. For more details please see the link:http://users.utcluj.ro/~dtl/STLA/Cursuri/Rap_fading.pdf
Best wishes
Dear,
WIFI for high data rate.
an IEEE 802.15.4 transceiver for low data rate.
the popular transceiver for the IEEE 802.15.4 protocol is the XBee module, but it is much more expensive.
Dear Khalid,
As compared to WiFi,Xbee offers low data rate and best suited for cases like sending small bits of information, sensor readings, instructions, etc
