TELECOMMUNICATION ASSOCIATIONS• EIA (Electronic Industry Association) - The standards address commercial building cabling for telecom products and services. The three standards are formally titled ANSI/TIA/EIA-568-B.1-2001, -B.2-2001, and -B.3-2001.
•TIA (Telecommunications Industry Association) – A global trade association headquartered in the United States that represents about 600 companies. TIA helps create universal networking standards for the telephone, data and the convergence of these industries.
•BICSI (Building Industry Consulting Services International) - The organization has membership in nearly 100 countries. This organization's certifications are considered the defacto certification for cable installers and designers who specialize in complex voice/data cable layouts.

10 YEARS AGO
• 10 Mbps Ethernet
• 100 Mbps Fast Ethernet
• 10/100 Mbps Switched Ethernet
TODAY
• 10/100 Mbps Switched Ethernet
• Gigabit Ethernet – 1,000,000,000 bps
• 10 Gigabit Ethernet – 10,000,000,000 bps
OVER THE LAST 10 YEARS TRANSMISSION SPEEDS HAVE
INCREASED 1000 TIMES IN THE HORIZONTAL AND 100,000

FIBER BACKBONE (LAN & WAN)
THE DESIGN OF A BACKBONE SYSTEM DEPENDS ON:
1. THE DESIRED SPEED
2. OVERALL DISTANCE OF THE CABLE RUN
3. OPERATING WAVELENGTH
= CABLE TYPE
FIBER TYPES:
62.5 Micron multi-mode (obsolete)50 Micron multi-mode (1G-10G)9 Micron singlemode (40G-100G)
FIBER BACKBONE (LAN & WAN)

BANDWIDTH
FIBER OPTIC CABLE
Fiber Optic Cable bandwidth varies from system to system . The end-to-end bandwidth of a fiber system is related to the respective bandwidths of its component parts.
Essential elements of end-to-end bandwidth are:
• Transmitter (type and wavelength)
• Fiber Optic Cable (distance)
COPPER
15 YEARS AGO
• Cat3 – 16 Mhz (Telephone)
• Cat4 – 20 Mhz (obsolete)
• Cat5 – 100 Mhz (obsolete)
TODAY
• Cat5e – 100 Mhz+ (VoIP)
• Cat6 – 200 Mhz (Gigabit)
• Cat6A – 550 Mhz (10Gigabit))
• Cat7 – 600 to 700 Mhz (M.Media)
CATEGORY 5e/6• CAT5e easier and less expensive to install than CAT6
but no “Headroom” for Gig (BVH recommends Min.6)• Will not support upcoming Technologies (10G)• 3-5 years away from the end of its lifespan
• Latest standard UTP cable (Supports 10G)• Difficult and time consuming to install• Very sensitive
EMI Temperature
CATEGORY 6A
CATEGORY 7• Shielded Cable•Category 7 is around the corner……
WIRELESS LAN (WLAN)
BASIC WLAN
Access Point
Wired Infrastructure
WLAN’s benefits:
• Mobility
• Reliability
• Ease of installation
• Affordability
• Scalability
Disadvantages
• Security (RF)
• Speeds (54Mbs)
• New N (300Mbs)!
WIRELESS LAN (WLAN)
PRODUCTS
• Access Points• Wireless Nic’s
STANDARDS
• 802.11a/b/g (Overlapping Channels 1,6,11) for speeds up to 54Mbs)
• 802.11n – Recently adopted standard now with multiple radios (1,6,11) allows up to 300Mbs +
VOIP – DOES THE NETWORK HAVE THE CAPABILITY AND NEED???
ADVANTAGES OVER TRADITIONAL TELEPHONY:
• Lower costs per call, especially long distance
• Lower infrastructure costs
• Unified Messaging
DISADVANTAGES
• Need reliable network with QOS
• Still young technology but rapidly replacing
TDM (PBX Technology)
• Need higher level technical expertise to
implement and maintain as network platform
AUDIO VISUAL

Video conferencing
VIDEO OVER UTP
• Media Retrieval
• Security /Surveillance
Cameras / Network Servers
Need Large Storage (T-Bytes)
Power over Ethernet (PoE)
Shared Network Connectivity
POWER OVER ETHERNET
802.3af up to 12.95Watts over UTP
The IEEE 802.3af PoE standard (ratified June, 2003) provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) to each device. Only 12.95 W is assured to be available at the powered device as some power is dissipated in the cable.
Power Options
• Midspan (hard-wired)
• Within switch (auto-sensing)
Equipment using• IP Phones
• Wireless Access Points
• IP Cameras
ITS NOT “JUST A WIRE” ANYMORE
TODAYS TECHNOLOGIES IMPACT THE CABLE INFRASTRUCTURE:
• Gbe (Horizontal and Backbone)
• 10Gbe (Horizontal and Backbone)
• Power over Ethernet
• Voice Over I.P.
= ADDITIONAL PATHWAYS, SPACES AND RACK SPACE!!!
* The ENTIRE Cable Infrastructure Can Only Run As Fast As Its Weakest Link
SUMMARIZE
• TODAYS TECHNOLOGIES IMPACT THE ENTIRE CABLE INFRASTRUCTURE
• CAREFUL PLANNING IS REQUIRED
• FUTURE TECHNOLOGIES CAN RUN SEAMLESSLY OVER A STANDARS-BASED
CABLE INFRASTRUCTURE!
