    Ethernet Wiring Standard; Which One Is Right? There are many standards for crimping Twisted Pair cables, these standards specify

    the order in which the wires go to ensure compatibility with other devices. The

    intention of this article is to show you the two most common wiring layouts and

    give you some tips in which may be better for your applications.

    Ethernet uses two standards, TIA/EIA568A and TIA/EIA568B. These standards

    specify the wire order in the RJ45 Plug/Socket. These two standards are used

    within the Air-Stream network and the wider community. So which one should you

    use? There is much debate within industry which is the right one to use. The

    simple answer is, they are both right. This news isn’t all that helpful though; what

    is helpful is knowing some facts about what cable you are using and what you are

    using it for.

  • Ethernet Wiring Standard; Which One Is Right? Many cable manufacturers specify

    which standard to use, this is not

    always an easy thing to find. Standard

    CAT6 and Outdoor CAT5e/6 specify the

    use of the TIA/EIA568B standard of

    crimping this however doesn’t mean

    that you cannot crimp that cable in the

    TIA/EIA568A standard but you may

    find it more difficult.

    Some cables such as the Ubiquiti

    Toughcable specify that you should use

    the TIA/EIA568B standard, if you

    attempt to crimp in the 568A standard

    you may find it difficult; this is due to

    the arrangement of the pairs

    within the cable sheath.

    So the information that you need to

    know. The pin outs and the standard

    that is used throughout the

    majority of the network.

    The following graphics show the two

    different pin outs that are commonly

    used, TIA/EIA568A and TIA/EIA568B.

    The Air-Stream network team

    commonly use the TIA/EIA568B

    standard on Ubiquiti Toughcable as do

    many members. As always if you are

    unsure about something |

    contact the Network team

    ( network @ air-stream.org )

    and come along to one of our builds.

    There is no better way to learn about

    wireless networking than by

    participating in a build!

    Network Updates

    High Gate Park

    As a part of the final 802.11n upgrades

    from 2012 High Gate Park was treated to

    two new dishes to finish this project off.

    The link to Skye was upgraded from a Hills

    26dB Single Polarity Grid to a Ubiquiti

    NanoBridge M5-25 Dual Polarity Dish. This

    has significantly increased the bandwidth

    between the sites. The other upgrade was

    finishing off the relocation of the

    HighGatePark-Ridgehaven link to

    HighGatePark-FPA-Teringie. The Hills 29dB

    Single Polarity Grid was exchanged for a

    Ubiquiti RocketDish 5G30. The photo on

    the right of this page is how the Northern

    mast now looks at High Gate Park.

    Gulfview Heights

    Upgrades were performed last weekend

    on Gulfview Heights to increase 5ghz

    coverage for the north western suburbs

    and to initiate the upgrade between EARC

    and Gulfview Heights. A 90 degree 5ghz

    sector was installed pointing West which

    will allow many members to connect to

    another great site. It will also allow

    IngleFarm to connect with its spare dish as

    a redundant path for when UniSA is down

    due to power works. The link to EARC was

    also upgraded from a Hills 26dB Single

    Polarity Grid to a Ubiquiti RocketDish

    5G30, as EARC does not yet have a Ubiquiti

    dish at the other end the link has been

    connected to one of the 5ghz sectors at

    EARC which is still giving >30mbit of

    throughput! You can see photos of this

    upgrade on the second page of this Air-

    Zine.

    Upcoming Projects

    Suntrix-Hermitage is a new build in

    Lower Hermitage, this will provide

    amazing connectivity between EARC

    and Modbury North.

    EARC is half built, now awaiting

    more radio gear to be installed.

    Q: What is ‘Air-Stream’? Air-Stream Wireless was established by a handful of dedicated wireless enthusiasts in 2001 and became an Incorporated Association in September 2002. It is the first and largest Community Wireless Network (CWN) in South Australia to successfully build a Wide Area Network (WAN) using wireless technologies. With hundreds of active members the network now forms part of the largest community wireless network in Australia and is continuing to grow with the help of wireless enthusiasts and radio amateurs across Adelaide and Australia.
