TETRA System Deployment in Saudi Aramco

The new system will enhance the following:

•Network congestion •up to date technology feature•Improve quality•Interference•Overcome the discontinued manufacturers support

14

Conclusions TETRA is the technology that will take the

radio professional users to the new millennium

Interoperability testing is creating real competition

TETRA provides the demanding multimedia services needed now and the future

Data applications offer concrete benefits Completely secure networks can be made

with TETRA
