respected in wlan 802.11a they have mentioned that the data rates varies from 6,9,12,24,36,48,54 Mbps . So upon what basis thus these data rates varies and why...
... The data rate depends on the modulation and coding used. The modulation at lower rates is more robust than the one for higher rates. So depending on the...

Hi all, Is there any to find the signal strength between any two nodes in ad hoc networks. using softwares like netstumbler we can find the signal strength...
... Each node in the network will have a different signal strength. So you will have to measure it at each node for the numbers to make any sense. Also, the...

what i mean is from each node i should be able to measure the strength of the signal from all the other nodes. As u said there are n*(n-1) values. How can i...
Dear all, 802.11e specify a method to reserve bandwidth through tspec negotiation, and this is only initiated by a qsta in qbss. In the event that an...
... CW, Please note that the TSPEC-based reservation is only for the HC (QAP) to schedule polls to the QSTA. It is not a true reservation in that other devices...

Hello Harshal, I understand that the scheduled TXOP is requested by an QSTA and granted by the AP SME. In this situation, if the AP SME is not aware of the AP...

Harshal, I need more information here. We assume 2 cases: Case 1: A QSTA knows it requires quaranteed downstream bandwidth and it gets scheduled TXOP from the...
... CW, If the downstream traffic starts before the TSPECs have been agreed upon, the AP knows about the resources used by the downstream traffic and how much...
