Muhammad Qammar Shehzad Managed Wifi – AirTies4920 Muhammad Qammar Shehzad

What are Wifi Challenges ? Limited range Interference Security is a concern High power consumption

Problem Statement Wifi coverage without compromising on capacity.

What should be considered Technology overview Simulation results Conclusion

AirTies Cloud Signal-to-noise ratio: SNR = signal power / noise power

AirTies Cloud

AirTies Cloud

802.11n vs 802.11ac

Use Case

Use Case

Use Case

Shanon Capacity Signal-to-noise ratio: SNR = signal power / noise power

Shanon Capacity Shannon formula: C = B.log2 (1 + SNR)

Bandwidth: 20 MHz

Only 2 devices

Propagation models Environments (indoor, outdoor, vehicular) ETSI Indoor Office test environment This environment is characterized by small cells and low transmit powers. Both base stations and users are located indoors.

Use Case 2

ETSI Indoor Office Propagation Path loss model: Where r is transmitter- receiver distance, n is no. of floors.

Benefits of AirTies4920 Dual band (2.4 GHz and 5GHz) Mesh Nodes talks to each other Backward Compatibility (802.11 a/b/g) Remote management (TR-069) No sticky clients

Other parameters to explore Open wifi Interference Weather Outdoor to Indoor Range versus SNR
