4. PROTOCOLS AND TECHNOLOGY
Figure 4: Protocols
Globtel AIR fixed wireless system is basically a cable network without cables. Cables as the physical layer that are responsible for distribution
of CATV signal have been replaced by wireless technology which delivers CATV signal to the end user wirelessly. All other TV signal
transmission and data transmission equipment remain the same as in wireline cable network. Apart from few Globtel AIR equipment parts the
rest of the system components are standard DVBx and Docsis equipment. Depending on network topology a central CMTS with remote phys can
be used or an independent CMTS at each base station location.
All users connected via Globtel AIR system are seen by the cable network provisioning and management systems as they would be connected
through wireline coaxial cable. All protocols used by Globtel AIR are standard Docsis 3.1 or DVBx and are the same as would be in the cable
network. Transmission technology is defined by the use of EdgeQAM, CMTS and other standard cable network components. Globtel AIR
equipment does not alter or interfere with any protocols, traffic, content, or any kind of data. Globtel AIR only shifts RF signals from CMTS
and EdgeQAM to alternative frequency at the base station location and back to standard cable network frequency at the customer premises.
Service portfolio and performance are the same as in the standard cable network. Customers can use standard cable modems and enjoy all
services like live CATV, ultra-fast broadband, VoIP, VOD, OTT TV… The latency is comparable to cable network.
