BBHN 1.0.1 for Ubiquiti Release Notes

Please keep the following notes in mind when operating these devices and reporting issues.

Due in large part to the physical differences between Linksys and Ubiquiti devices, the following list of functional differences should be noted:

DMZ and LAN Port Distinctions

Since the Ubiquiti line of devices has only 1 Ethernet port, the standalone device only supports one wired-LAN connection.  If you want additional LAN connections, then you will need to add an outboard Ethernet Switch.  Connecting to that switch may require a cross-over cable rather than the standard straight-through cable.

If you need the WAN network, then you will require an outboard Ethernet Switch which supports 802.1q VLANs (virtual LANs).  Typically this would be a “Managed” switch.  Configure the VLANs as follows:

  • Untagged = LAN
  • vlan1 = WAN

Note: You will consume 2-ports in this configuration, so if you want to end up with the equivalent of what the Linksys WRT54 series device offers, then you will need a 6-port switch.

Look to additional support for this configuration in the UBNT Support Forum.

Off-Channel Operation

Ubiquiti devices will not search for BBHN nodes off-channel.  The configured channel is the only one on which the device will operate.  We are currently evaluating the Linksys operational characteristics in this area and will likely attempt to conform them to this behavior.

Band-edge Vigilance

Linksys devices utilize the 802.11g standard where transmitted data are contained within 22MHz “channels.” However, if neighboring Ubiquiti devices have high-enough quality RF links, they can ramp up to 802.11n.  This standard operates within 40MHz channels.  In most all cases this will not be an issue, because BBHN networks are typically configured to their default, channel 1.  If you choose a different channel, then care must be taken to ensure the entire channel remains within its licensed operating spectrum.  For example, if it’s being operated on 2.4GHz in the US under Part 97, then it must be kept on either channel 1 or 2.  All higher numbered channels could cause the devices to exceed the upper limits of the ham band.

Encryption

These devices can be configured to either permit or prohibit known encrypted traffic on the RF link.  It is up to you to decide which is appropriate based on how it will be used and the license under which it will be operated.  These rules vary by country, frequency, and intended use.  You are encouraged to read and understand these rules.

These devices are pre-configured with no restrictions as to the type of data being passed and are currently compatible with the Linksys WRT54G-series BBHN firmware.

Instructions are provided if you wish to prohibit known encrypted traffic on the RF link.  This includes: SSL (443), SSH (22), Node SSH (2222), and Encrypted Email (465, 995, 993).

The forum will not entertain discussions on which of these options is appropriate for a given situation.  Ultimately the control operator is responsible for making that determination.

Output Power

Ubiquiti devices output significantly higher power-levels than their Linksys counterparts.  Based on the model and antenna gain, you can easily exceed 47 CFR Part 15 effective radiated power (EIRP) limits.

We believe the power level control we provide you in the user interface is generally accurate, although we have reason to believe we may overstate the actual power level by as much as 3dB in NanoStation Loco M2 configurations.  We would be grateful for anyone with an accurate means of measuring this to post their observations to the forum.

Power levels for devices with dual-antennas, such as the Rocket M2, when configured in diversity mode, split the configured power between both antennas… causing each port to individually be 3db below the configured power.

Power levels have a dependency on the configured antennas. You may notice that you cannot set full max power of the device when using only a single antenna.   You may also notice that you cannot use the minimal power listed in the power drop down window.  Some of these devices have internal, off-chip amplifiers which are kept in their linear operating range by limiting the upper/lower input power levels.
