26 Designing for Next Gen Wi-Fi Applications
Fighting for wireless bandwidth, especially in tightly
packed device-filled environments such as stadiums and
rallies is sketchy at best. Over-subscribed carriers are part
of the problem. They just cannot provide enough raw data
to so many people in real time.
But competing in the same space as some cellular
bandwiths is Wi-Fi, ZigBee™, Bluetooth®, DECT, HAL, and
several other protocols we may be aware of–all sharing
RF space, all using different modulation schemes,
channel widths, channel spacings, and frequency-hopping
algorithms.
As next-generation services and devices emerge, more
frequencies, bandwidth, coexistence, and interference
immunity are needed. This means claiming more of the
spectrum that was lost using older technologies. Read on
to learn how Bulk Acoustic Wave (BAW) technology offers
a promising solution to maximize spectrum utilization by
supporting more precision filtering to recover stronger,
more reliable signals with greater noise immunity.
Maximizing Spectrum Utilization
Spectrum utilization is the key, and while the move from
3G to 4G increased from 5 bands to 20 bands, soon 40
4G bands will be up for grabs, all trying to recover clean
signals from a world of muddying interference.
In other words, reaching deep into a turbulent pool of RF,
more precision filtering is needed to recover stronger
and more reliable signals with improved noise immunity.
And with handheld devices that feature multi-protocol
transceivers that can operate simultaneously, the need for
40 filters is not uncommon.
Even within home settings, Wi-Fi routers suffer and
end-point devices fall victim here as well. We need more
reliable data, more throughput, fewer retries, more
effective range, more simultaneous channels, and so on.
