5G Networks Flashcards
What is 5G technology?
5G is the fifth generation of wireless communication technology, offering higher speeds, lower latency, and improved connectivity compared to previous generations.
What are the three primary frequency bands in 5G?
Low Band: Covers long distances, penetrates buildings well, but has slower speeds.
Mid Band: Best for cities and suburbs, balances speed and range.
High Band (mmWave): Offers ultra-fast speeds but has a short range and weak penetration.
What is network slicing in 5G?
A feature that allows a single 5G network to be divided into multiple virtual networks, optimized for different uses (e.g., self-driving cars vs. video streaming).
What are the key benefits of 5G technology?
Faster data transfer: Enables real-time applications like telemedicine and virtual reality.
Improved energy efficiency: Uses only 15% of the energy that 4G requires for the same data transfer.
Supports IoT growth: Enables more connected devices with better power efficiency.
Economic growth: Creates new business models and innovations.
- How does 5G impact businesses?
Enables automation and smart infrastructure.
Facilitates the use of AI, augmented reality, and IoT.
Increases operational efficiency and connectivity.
Provides a competitive advantage to early adopters.
What industries benefit the most from 5G?
Healthcare: Remote monitoring, telemedicine, and emergency response.
Manufacturing: Automation and real-time analytics.
Transportation: Self-driving cars and smart traffic management.
Entertainment: Faster streaming and immersive VR/AR experiences.
What are the challenges of 5G adoption?
High infrastructure costs: Upgrading towers and small cells is expensive.
Security risks: More connected devices create more entry points for cyber threats.
Regulatory hurdles: Different countries have varying spectrum allocation policies.
Limited rural coverage: Low population density areas may not receive strong 5G signals.
What are the cybersecurity risks of 5G?
Supply chain vulnerabilities: Dependence on multiple equipment manufacturers.
Data privacy issues: More connected devices increase exposure to breaches.
Public Wi-Fi threats: Open 5G networks can be exploited by hackers.
IoT security weaknesses: Many IoT devices lack built-in security features.
How does 5G enhance energy efficiency?
Uses advanced power management to reduce energy consumption.
Features sleep mode capabilities to limit energy use during low data traffic periods.
Could reduce global CO2 emissions by half a billion tonnes by 2030.
What factors influence a business’s decision to implement 5G?
Financial resources: Larger firms can invest more easily in 5G infrastructure.
Location: Businesses in urban areas have better access to 5G networks.
Compatibility: Legacy systems may need upgrades to work with 5G.
Return on Investment (ROI): Businesses must assess potential profitability.
What is the estimated cost of full 5G deployment?
In the UK, full 5G coverage by 2030 is expected to cost approximately €18 billion.
Individual business investments can range from hundreds of thousands to millions of dollars.
What are the regulatory challenges of 5G?
Governments set different regulations that impact rollout speed.
Spectrum allocation issues may cause delays in deployment.
Legal considerations for cybersecurity and privacy need to be addressed.
What is the future potential of 5G?
Could pave the way for 6G, which aims for even faster speeds and zero-latency communication.
Supports emerging technologies like holographic communication and AI-driven automation.
May enable fully autonomous cities and connected smart grids.
