This presentation covers an approach and methodology to integrating WLAN capacity planning into the WLAN design process to allow network engineers to effectively meet growing capacity demands by clients on wireless networks. It defines what capacity means for a WLAN, what factors determine capacity, provides an approach to designing for capacity, and where capacity planning should be integrated into the overall WLAN design process.
Effective capacity planning is required for all WLANs, not just high-density environments.
This information was presented at the WLAN Professionals Conference (2014).
You can also

4G and 4G+ networks employ a type of waveform called orthogonal frequency division multiplexing (OFDM) as the fundamental element in the physical layer (PHY). In fact, almost all modern communication networks are built on OFDM because OFDM improved data rates and network reliability significantly by taking advantage of multi-path a common artifact of wireless transmissions. However as time and demands progress, OFDM technology suffers from out-of-band spectrum regrowth resulting in high side lobes that limit spectral efficiency. In other words, network operators cannot efficiently use their available spectrum because two users on adjacent channels would interfere with one another. OFDM also suffers from high peak-to-average ratio of the power amplifier, resulting in lower battery life of the mobile device. To address OFDM deficiencies, researchers are investigating alternative methods including generalized frequency division multiplexing, filter bank multi-carrier, and universal filter multi-carrier. Researchers speculate that using one of these approaches over OFDM may improve network capacity by 30 percent Continue reading
