Testing Suites

  • IxChariot

Access Points and Roaming

  • Vendors
    • Meraki
    • Meru Networks
    • Cisco
    • Motorola
    • Ubiquiti

Roaming Standards

  • IEEE 802.11F scrapped
  • 802.11r
  • 802.11k
  • Some WING something?
  • Hostapd is supposed to have some of these....
  • Most proprietary solutions require hardware controllers cisco, etc
  • UBIQUITI - Zero Handoff Roaming
    • Currently available in the beta version of the UniFi Controller v3.
    • Not currently supported by the UAP-AC or UAP-AC Outdoor.

UBIQUITI UniFi

  • poe:
    • for those of you upset by the 24v pie then buy the pro model unifi AP or the new ac model both of those are 48v standard pie and work off a regular pie switch
  • ex:
    • We have our WiFi network setup using Unifi APs and it works great. As a Bank we have to guard our WiFi network very closely and while the UniFi gear could not do MAC whitelisting we did couple it with a (oh no here it is) POE Cisco switch that we do our MAC filtering on. Linked up to AD for RADIUS and a hidden SSID and we are about as secure as you can get. Usually if you look long enough and do enough homework you can figure out a way to get what you want without having to spend a bunch of money.

Notes

  • What about the mega-APs like the Xirrus that have an array of multiple radios in a single housing? According to the Xirrus website their top-end unit has 16 radios, has a max bandwidth of 7.2 Gbps and supports 1,792 associated users! But, they will cost you...
  • Spiceworks:

Cisco offers a wide variety of products and services to support SMB to enterprise-class networks. We have different products you can choose from depending on your requirements and the features you need, thus the difference in pricing. Feature and application-wise, you have better options with Cisco. :)

If you are curious about the pricing of the different APs, you can check the information below.

For small networks, you can choose the Cisco SMB WAPs: http://www.cisco.com/cisco/web/solutions/small_business/products/wireless/index.html-tab-AccessPoints

For midsize networks (and cloud management) you can go with Cisco-Meraki: https://meraki.cisco.com/products/wireless

For enterprise and large network, you can choose the Aironet APs:

Notes

MCS15 (130mbps?) = see 'my post'

  • Don't forget to turn off AirMax and use a 20 MHz channel width, or your campers won't be able to associate to the AP.

MCS stands for Modulation and Coding Scheme. The 802.11n standard defines a total of 77 MCS. Each MCS is a combination of a certain modulation (e.g., BPSK, QPSK, 64-QAM), coding rate (e.g., 1/2, 3/4), guard interval (800 or 400 ns), and number of spatial streams. Support for MCS 0-15 is mandatory for 802.11n APs and support for MCS 0-7 is mandatory for 802.11n clients.

Calculating Signal

Cable

  • Microcom...PRO - $189, CARRIER - $249
  • Streakwave...PRO - $145, CARRIER - $185
  • Amazon and eBay...Shireen DC 1021 (similar to PRO cable) - $155
  • Both PRO and CARRIER GRADE are rated for CAT 5E up 1 Gbps
    • PRO has only foil shielding
    • CARRIER has foil and wire mesh shielding, and a plastic anit- crosstalk divider.

My Post

Some mounting ideas

Just a flange and bent pipe for the side of a building.

Wifi

  • 2x 19db panel antennas
  • 2x waterproof enclosures
  • 2x wrt54gl (250mw)
  • 2x POE injectors

Notes

Connectors for Dish

  • Antenna Female N

Fresnel Zone


1st Fresnel Zone Radius: 7 ft at 0.03 Miles (2 m at 0.05 Km)
60% No Obstacle Radius: 3 ft (1m)

Signal-to-Noise

Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise.
