The
future presents two major realistic new technologies that will improve
on current wi-fi: 802.11n and WiMax. Both these technologies essentially
are new standards that allow for stronger and more efficient communication
between devices. With this, both technologies present increased speed
and range, but in different methods
802.11n. The
creation of this standard was for the purpose of increasing reliability,
the security, and the speed of wireless networking from its predecessor,
the 802.11g spec. Though wireless technology through 802.11g has seen
a great expansion due to advances, there are still issues needed to be
dealth with.
The advent of 802.11n was
supposed to change how wi-fi gear was often highly susceptible to interference
from cordless phones and other devices and the slowness in speed to old-fashioned
Ethernet. The standard utilizes a powerful smart-antenna
technology called MIMO, which stands for multiple
input multiple output. MIMO essentially allows a wireless device
to make more efficient use of "data transmissions in indoor environments"
[Fear 2005]. This achieved through multiple antennas on routers and access
points to maximuze throughput (definition below)
in indoor environments. Indoor environments greatly affect performance
of wireless communications, and MIMO aims to allow the clearest data path
on the fly so that both range and throughput will be increased as a aresult.
Wi-Max. An
acronym that stands for Worldwide Interoperability for Microwave
Access. Essentially, this technology is the new standard
created by IEEE, classified as 802.16. The technology is similar to wi-fi,
but improves on certain aspect such as performance in throughput and distance
for usage.
Although still in its early
stages of development, WiMax is anticipated to being a wireless metropolitan
area network technology in which coverage covers a massive amount of area.
It considered to able to connect IEEE 802.11 (Wi-Fi) hotspots
with each other and to other parts of the internet, which be a fascinating
innovation to current hot spot technology now. Additionally, because it
is planned for WiMax to operate on much higher frequencies than normal
Wi-Fi, there will be less radio interference from other devices because
there are fewer devices that operate at these frequencies. This would
inevitably increase speed and distance by a great deal. According to WiMax
proponents, the technology should be able to simultaneously support more
than 60 business with T1-type connectivity and well over
a thousands home at the connectivity experienced with most DSL-level services.
Researchers consider WiMax as a "bold attempt at forging many technologies
to serve many needs across many spectrums" (Wikipedia 2005). With
these improvements, WiMax will be able to provide multiple additional
opportunities for applicability such as VoIP, DVD quality video streaming,
gaming, and much more.
Definitional Terms
