List the logical channels provided by L2CAP.

Random access for data oriented networks Session 1. What is meant by hard handoff?

nettworks Click here to sign up. Give the classifications of Handoff. Determine the transfer time of a 20 kB file with a mobile data network with the transmission rate of 10 Kbps.


List the four layers involved in SMS. What are the design consideration requirements for TDMA? Explain in detail about Bluetooth architecture 8.


Explain the need for demand based routing protocol for wireless sensor networks. Explain the services provided by IEEE That is, if no channel is available, the handoff is blocked and the call is held on the current channel in the old cell until the call is completed nptes when the failing link is no longer available.
