LTE and WiMAX are common transmission systems

Question 3

WiMAX

Answer 3

Broadband Wireless Access IEEE 802.16 is a well known example of wireless broadband.
WiMAX can potentially deliver data rates of >30 Mbps

Question 4

5G

Answer 4

Uses higher frequencies than previous tech, allowing for higher transmission speeds up to 10 Gbps but at reduced distances. Can provide authentication, authorization, and accounting (AAA)

Question 5
