TV White Space (TVWS) and Ethernet are two different technologies used in networking and communication, each with its unique attributes and applications. TVWS refers to the unused broadcasting frequencies in the terrestrial TV frequency range, while Ethernet is a common method of networking computers in a local area network (LAN) or wide area network (WAN).
TVWS technology can be used to provide wireless broadband internet in rural or remote areas, exploiting the excellent propagation characteristics of TV frequencies to cover large areas with relatively low infrastructure costs. On the other hand, Ethernet is a wired technology used for creating local area networks, offering reliable and high-speed connectivity over short to medium distances.
Here’s how TVWS could be integrated with, or utilized alongside, Ethernet in a network setup:
- Backhaul Connectivity:
- TVWS can serve as a wireless backhaul link connecting remote or rural areas to a central network point, which is then connected to the broader internet infrastructure via Ethernet or other wired connections.
- Last-Mile Connectivity:
- TVWS can provide last-mile connectivity to end-users in areas where wired connectivity (like Ethernet) is not feasible or cost-effective. In such setups, Ethernet could be used within individual premises, while TVWS provides the external connection to the broader network.
- Ethernet Bridging:
- Devices known as wireless Ethernet bridges can potentially be configured to operate in the TVWS bands, providing a wireless extension of a wired Ethernet network over longer distances than typical Wi-Fi or other wireless LAN technologies.
- Hybrid Network Architectures:
- A network could be designed to use both Ethernet and TVWS technologies, exploiting the strengths of each. For example, Ethernet could be used for high-speed, reliable connectivity within buildings, while TVWS provides wider-area coverage to connect multiple sites or provide outdoor connectivity.
- Conversion Devices:
- Specialized network devices or appliances could be used to convert between the TVWS and Ethernet domains, allowing seamless communication between wired and wireless segments of a network.
- Network Edge Connectivity:
- In edge computing setups, TVWS could be used to connect edge devices or local data aggregation points to central data centers or cloud services, with Ethernet used within the central facilities for high-speed, reliable connectivity.
Utilizing TVWS and Ethernet together in a complementary manner can enable network connectivity solutions that are both cost-effective and adaptable to a wide range of geographical and infrastructural scenarios.
