7522 WIRELESS LAN TRAINER

ADTRON’s LAN Trainer Model 7522 is a versatile system that supplements courses on computer networks and LAN.

 Fundamentals of wireless networking,

knowledge of all wireless network layers, cable designing and building of complete wireless network of computers.

 Understanding and Implementation of various topologies using different standards given by IEEE, protocols, measurement of error rate, throughput and effect of errors on protocols.

 Software provides graphical representation of data with differentiation of packet to be

transmitted, packet being transmitted, packet transmitted with acknowledgment.
