Good Stuff......trying to post in between jobs, not so good.
The rapid growth of bandwidth requirements and the changing role of enterprise networking are causing disruptive change in the enterprise Local Area Network (LAN). Incumbent vendors are recommending upgrading Ethernet switches to 10 Giga-bit Ethernet (GbE) uplinks which typically require single-mode rather than multimode fiber optic cable and replacement of lateral CAT 5 cable with CAT 6 cable. Enterprises facing such disruptive change to either an existing enterprise site or a new enterprise site have the opportunity to dramatically reduce Total Cost of Ownership (TCO) by moving to a Passive Optical LAN (POL) solution, rather than continuing with the Present Mode of Operations (PMO) which uses a two- or three-tier switched Ethernet solution.
We know low cost bandwidth would fundamentally change everything. Information technology will be more about video than text or pictures .
With the Internet today we are close to where television started over fifty years ago. Video is widely viewable today online around the world ( I.e YouTube ) but the experience varies considerably. That will change over the next few years as good or great quality video will be delivered to any screen you want it on (tv, computer, mobile devise).
802.11n have now placed wireless on a par with structured cabling systems' performance.
802.11n is a new multi-streaming modulation technique.
EEE 802.11ac
is a wireless computer networking standard of 802.11 currently under development which will provide high throughput Wireless Local Area Networks (WLAN) below 6 GHz[1] (what is commonly known as the 5 GHz band).
Theoretically, this specification will enable multi-station WLAN throughput of at least 1 Gigabit per second and a maximum single link throughput of at least 500 megabit per second (500 Mbit/s). This is accomplished by extending the air interface concepts embraced by 802.11n: wider RF bandwidth (up to 160 MHz), more MIMO spatial streams (up to 8), multi-user MIMO, and high-density modulation (up to 256 QAM).
On January 20, 2011, the Initial Technical Specification Draft 0.1[2] was confirmed by IEEE 802.11 TGac.[3]
Standard finalization is anticipated in late 2012, with final 802.11 Working Group approval in late 2013.[4] According to a study, devices with the 802.11ac specification are expected to become common by 2015 with an estimated 1 billion spread around the world.[5]
As of September 2011, there are no consumer devices implementing the draft specification. ......lot of stuff done since then
802.11 came online in 2009 .....always keep in mind GM's steps of action, (PR's)
Passive optical network (PON) .....visual really telling when thinking about cost of parts/labor
1 kilobit = 0.0009765625 megabits ...cell phone compression of 160kbits....puts things in perspective
160kbits = 0.15625 Megabit = 0.00015 Giga
.......802.11n came online in 2009 Hmmmm..........interrupted with chores
