Upload and Download

  • What’s the difference?

– Upload is sending newly created information (files, data, pictures, video, gaming commands) and making it available for use on the internet network.

  • Linked In
  • DropBox
  • Face Book

– Download is pulling stored information or purchased media (music, books, pictures, VIDEO) from sources over the internet for your use.

  • Netflix
  • YouTube
  • iTunes

Basic Terminology

Bits and Bytes

  • A terminology for digital information transfer rates (bits)

and storage (Bytes)

– bit = 0 or 1 – Nibble = 4 bits – Byte = 8 bits – KiloByte (KB) = 1024 Bytes – MegaByte (MB) = 1024 KB – GigaByte (GB) = 1024 MB – TeraByte (TB) = 1024 GB – PetaByte (PB) = 1024 TB – ExaByte (EB) = 1024 PB http://lifehacker.com/the-difference-between-bits-and-bytes- and-why-it-matte-510705022

Average Sizes of some common residential items:

  • A picture taken with my Android Device = 1.4 MB
  • A photo taken with a typical digital camera = 4.0 MB
  • A song download from iTunes = 5.0 MB
  • A CD worth of data = 560 MB
  • A HD movie on Netflix (varies) but today = 3.8 GB

– Future Sony 4K HD Movie = 50 GB (uncompressed)

Perspective on Size

Sizes of a large business file:

  • Digital Lidar file flown by a fixed wing aircraft for a 50

mile segment of new transmission line imaging 800’ in width @ 6 data points per square meter:

= 500 GB file

  • If my vacation picture (1.4 MB) taken on my Android

device was the size of a golf ball… (Surface Area of a Sphere)

  • Dia. = 1.68”

Perspective on Size

  • Then a 50MB GIS database has the surface area

equivalent to a men’s basketball.

  • Diameter = 10”

Perspective on Size

  • Then the new 4K HD Sony movie = 50 GB would require

2.6 of the largest beach balls I could find. (D = 10’)

  • Diameter = 26.75’

  • The Finley 500 GB Lidar file would require a football

field

  • Diameter = 84.6’ (28.2 yards)

  • A 1 TeraByte file…..Surface Area of a sphere near the

diameter of the halo of the space needle. Dia =138’

  • Diameter = 121.16’

FCC National Broadband Plan Goals

  • Current

– 4 Mbps down / 1 Mbps up actual data rates to all homes

  • 2015

– 50 Mbps down / 20 Mbps up actual data rates to 100 million homes

  • 2020

– 100 Mbps down / 50 Mbps up actual data rates to 100 million homes

How Much Bandwidth is Enough?

How Much Bandwidth is Enough?

  • The average broadband package today is

approximately 7.0 Mbps

  • “Fast” broadband is typically advertised as being
  • ver 30 Mbps
  • CATV & FTTP companies are rolling out 50 -100 Mbps

services, promising 150 Mbps and 300 Mbps services

  • FTTP can deliver over 1 Gbps services and is

currently rolled out to over 40 cities

slide-13

Future Bandwidth Requirements

  • Many experts envision 100 Mbs to the customer within the

next 5 years:

  • As HDTV becomes the normal TV medium
  • As 20-50 Mbps High Speed Internet becomes the norm to

support:

  • Multimedia Applications (i.e.. Online Gaming)
  • Streaming Video (i.e. YouTube, Netflix, Apple TV)
  • The Cloud increases the need for higher upload speeds
  • Symmetrical bandwidth becomes more important
  • Gigabit Speeds for future applications

  • Quad HD Video-2160p-4K UHDTV
  • It has a resolution of 3840 x 2160.
  • Product introduction started in the 2012
  • 55” Sony 4K Ultra HD TV run $ 5,000 at Best Buy
  • It requires 4 times the bandwidth of a HD signal
  • Large screen sizes work against higher

compression levels

  • 8K UHDTV
  • has a resolution of 7680 × 4320
  • It requires 16 times the bandwidth of a HD

signal

What’s Next for Video?

Over The Top Video

– A disruptive force in video content distribution – The customer purchases content directly from the Content Provider not from a CATV, Satellite or IPTV Service Provider – Content is downloaded over system to the customer’s device

Service Provider provides a pipe only

– Family TV Family time has been redefined with everyone watching their show on their own device – Multi-Screen Viewing and supplemental content

  • Watching and Tweeting or posting to Facebook

Network Recommendations

Below are the internet speed requirements and recommendations for playing movies and TV shows

  • n the Netflix website.
  • 1.5 Mbps- Recommended broadband connection speed
  • 3.0 Mbps- Recommended for DVD quality
  • 5.0 Mbps- Recommended for HD quality
  • 7.0 Mbps- Recommended for Super HD quality
  • 12.0 Mbps- Recommended for 3D quality

Wireless Broadband

– Benefits

  • Lower startup costs
  • Serve low density areas
  • Use as an “edge out” platform

– Challenges

  • Bandwidth limitations
  • Spectrum

– Licensed 700 MHz (Future 600MHz) – Non Licensed 900 MHz, 2.4 GHz, 5.8 GHz – “Registered” 3.65 GHz

  • Data Over Cable Service Interface

Specification

  • Allows for transport of Ethernet over coax

and fiber cable using CMTS (RF modems)

  • DOCSIS 3.0 support 300 Mbps downstream

speeds

  • DOCSIS 3.1

– 10 Gigabit downstream / 1 Gigabit Upstream – Planned Equipment availability in 2015

DOCSIS

  • Digital Subscriber Line common

deployment from traditional broadband providers.

  • Many “flavors” of DSL deployed over time
  • Most Common ADSL2+ or now VDSL
  • Bandwidth (down and up) vary with

distance of copper loop.

  • Active Optical Network is defined as an optical network where the Active Ethernet

component is directly sent to a single user.

  • No Splitters in the network.
  • OLT: Optical Line Terminal – Active optical to electrical unit at the C.O.
  • ONT: Optical Network Terminal – Active optical to electrical unit at the premise

  • Gigabit Passive Optical Network (G-PON)

– Shared bandwidth by subscribers connected to the same equipment port.

  • 2.4 Gigabit downstream
  • 1.2 Gigabit upstream
  • Equipment “dynamically divides” bandwidth to each

subscriber.

– Shared fiber to Fiber Distribution Hut (FDH).

  • Optical splitters “divide” light between subscribers.
  • 1x32 (1 input fiber and 32 output fibers)

  • PON: Passive Optical Network is defined as an optical network where the active

components are split and shared among users.

  • Splitter: Optical device that divides (downstream) and combines (upstream) a single optical

source to multiple destinations. In FTTP networks, this device is passive in that it does not require power.

  • OLT: Optical Line Terminal – Optical to electrical unit at the CO
  • ONT: Optical Network Terminal – Active optical to electrical unit at the premise
