4G & 5G BROADBAND

📡 4G: What makes it great?

  • All-IP network: Unlike 3G, 4G uses IP (internet protocol) for everything—including voice calls—so everything travels as data packets. 
  • Radio magic: Your phone sends signals to a base station (cell tower) via radio waves. The tower links you to the internet. 
  • Smart tech = faster speeds: Uses MIMO (many antennas for sending/receiving) and OFDM (breaking signals into smaller chunks) to boost speed, capacity, and reliability. 
  • Speed highlights: Typically 20–150 Mbps, with advanced 4G (LTE-A) reaching 300 Mbps or more. Latency sits around 10 ms. 

Why choose 4G & 5G

More spectrum = more power: 5G expands into higher frequencies—from low/mid to millimeter-wave (mmWave)—unlocking massive bandwidth and ultra-fast speeds .

Next-level OFDM + antennas: Builds on OFDM, with smarter beamforming and tiny “small cells” for dense, high-speed coverage .

Slices for every purpose: Network slicing lets carriers carve out separate “virtual networks” on the same physical infrastructure—one for gaming, one for IoT, one for video, etc.

Faster & snappier: Speeds peak at ~20 Gbps, latency drops below 1 ms, and capacity skyrockets—you can support millions of devices in a city block.

Voice via VoNR: Voice calls are handled over 5G data streams (VoNR), similar to VoLTE in 4G.

🔄 How they work together

5G often builds on top of existing 4G networks (called Non‑Standalone deployment):

Control plane via 4G, data plane via 5G gives fast data and stable connection.

In dense areas, 5G small cells take over; elsewhere you still use 4G.

🎯 Why it matters

  • 4G offers fast broadband speeds across the country
  • It is deployable almost immediately so can even be used as a back up if wired broadband goes down!
  • 5G can be very fast reaching over 150mbps.

In summary

  • 4G: Solid, all-IP, plenty fast for most mobile needs. 
  • 5G: Super-fast, ultra-low latency, massive device support—built on smarter spectrum use, small cells, and slicing.
