Multicast Advantages and Disadvantages

When sending the same data to multiple receivers, rather than send multiple copies all the way from sender to all the receivers, just send one copy and duplicate where paths diverge Better bandwidth utilisation Less host/router processing Receivers’ addresses may be unknown A possible thing to use for IPTV over WiMAX. Multicast Advantages Enhanced Efficiency: … Read more

Why Diversity Antenna Systems Required

Basically Diversity Antenna required because of Signal Rich at mobile or BTS by reflection and this change value of its level and quality either good or bed. Let’s understand in detail. NEED OF DIVERSITY In a typical cellular radio environment, the communication between the cell site and mobile is not by a direct radio path … Read more
