First Key Takeaway - Wireless

  • Understanding Wireless networks and their impact on:

The connected home

  • IEEE 802.11 a/b/g/n/ac
  • IEEE 802.15.4 - Zigbee
  • ITU G.9959 – Z-Wave

Cellular Data Networks

  • 2G EDGE
  • 3G CDMA
  • 3.5G HSPA+
  • 4G LTE
  • 4G LTE

Small and Medium Business Networks

  • Multi Access point and Controller Based solutions

Enterprise

  • Authentication – 802.1x, AAA
  • Implementation of Network Admission control

Service Provider

  • Service Provider Wifi (walled garden, paywall, etc).
  • Applying this knowledge to understand the hardware capability of

Wireless devices

Second Key Takeaway – Routers (RSGs)

Residential Gateway Routers have become advanced with Enterprise class features:

A look at all-in-one RSGs w/SFP fiber termination capability. capability.

We will review new features in these gateways that

  • ffer new Network capabilities for the home and SMB.

State of the AZ / NM Networks

Tier 1 Cellular providers showing up in rural areas. Fiber on the rise.

Although declining, copper is still a significant percentage (~50%?) of all plant.

Wi-Max or Fixed LTE supplements some ILEC/ CLEC markets. Wi-Max or Fixed LTE supplements some ILEC/ CLEC markets. No IPv6 in New Mexico or Arizona (?) [yet!] Stimulus networks now entering service – lots of DWDM. Metro-Ethernet interconnects with other Telcos are now more common at 1gbE or 10GbE.

State of the Internet, Security and IPv6

  • Security:

Port 445 (Microsoft-DS) remained the most targeted port in the fourth quarter, growing to 30% of observed attacks.

  • IPv6
  • IPv6

Comcast in November 2013: “Today, over 25% (and growing) of Comcast’s Xfinity Internet customers are actively provisioned with native dualstack broadband Internet service. Native IPv6 support has been deployed to over 75% of our broadband network, and our goal is 100% in early 2014.” Google Fiber – all dual stack IPv4 and IPv6.

Google assigning a /56 IP address.

Wireless data growing by Leaps and Bounds…

Based on traffic data collected by Ericsson, the volume of mobile data traffic increased by 70% from the fourth quarter of 2012 to the fourth quarter of 2013, and grew approximately 15% between the third and fourth quarters of 2013. third and fourth quarters of 2013.

802.11-AC

  • Called “VHT” – Very High Throughput
  • Operates on 5Ghz only, why?

More channels for bandwidth!

  • 80/160mhz channels with 802.11ac
  • 256 QAM, but at short distances.

There will be two releases of 802.11-AC. Current releases do not include MU-MIMO, which is the true gigabit Wifi spec. It is hardware, not software updates to get to the version 2 spec.

Two related Protocols

  • IEEE 802.15.4

Zigbee

  • ITU G.9959
  • Z-Wave

defines a set of guidelines for sub-1-GHz narrowband wireless devices.

  • Both ZigBee and Z-Wave are supporting mesh network topology, which is a

strong requirement towards the revolution of “internet of things”.

  • With a “Gateway” device, you can control any piece of equipment that has

a built-in Z-Wave or Zigbee device. This list includes security systems, Smart Thermostat, your automatic door locks, video surveillance lighting and small appliance controls.

Z-Wave

Z-Wave operates in the 900MHz band It is proprietary. Z-Wave product is limited to 232 devices Less interference at the lower frequency, and Less interference at the lower frequency, and a longer wavelength that more easily penetrates walls and objects. Control lights, electrical outlets, fans, shades, drapes, irrigation, thermostats, security systems, door locks

Z-Wave

With Mesh Networking, the more devices that are added the better the network becomes.

Opposite of Wifi

As devices are added, they automatically join the mesh. mesh. They then create the most optimal pathways to send data, with each device able to act as a repeater for other devices. Should one device fail, the mesh self-heals, instantly creating a new transmission pathway.
