What kind of speeds can I expect? PDF Print E-mail

Actual transfer speed will vary based on network usage, number of active Internet connected gateways and wireless signal strength. The maximum amount of bandwidth one user can transfer is limited, with speeds similar to a low end DSL connection. This limit was put in place to prevent abuse of the network. You can expect speeds between one half and one megabit per second, depending on network factors.

 
What Makes DFW FreeNet Different? PDF Print E-mail

DFWFreeNet is a wireless mesh network built using inexpensive ($49-$99), readily available wireless access points. Traditional wireless access points cost hundreds of dollars and require an Internet or network connection at every access point, significantly increasing the cost of building the network. Our wireless repeaters are inexpensive and can relay data several times until it reaches an Internet connected access point, called a gateway.

  • To SSH into the Meraki, use “meraki” as the username and the Meraki’s serial number as the password (can be found on the bottom of the Meraki or in the Dashboard)
  • /storage is a persistent (so far Meraki has not had to overwrite this partition for firmware upgrades) partition
  • /storage/late-init.sh runs last in the boot sequence, useful for adding iptables rules, etc.
  • /storage/config stores the current Meraki configuration.
  • When connected to a Meraki mesh network (wired or wireless) you can access http://my.meraki.net to view the status of the node you are currently connected to and http://gateway.meraki.net to view the status of the gateway you are connecting to the Internet through.
 
Power Over Ethernet PDF Print E-mail

Though the the Meraki Mini Outdoor comes with a Power over Ethernet (PoE) adapter, other models do not. To lower cost, Power over Ethernet injectors have been built using a dual RJ-45 surface mount jack and either the power supply included with the Meraki Mini (7.5V), or a higher voltage 12V power supply for longer (50+ft) Ethernet runs.

Antennas PDF Print E-mail

The antennas we have tested so far have come from Hyperlinktech, which include a 9dBi and 5.5dBi with RP-SMA connector. The 9dBi omni-directional has been used mostly for outdoor nodes, they’re cheap and provide decent gain. The Bud NEMA Cable Gland .39”-.55” (Mouser part #563-NG-9515) fits the 9dBi omni-directional antenna nicely. We’ve found the 2dBi antenna included with the Meraki Mini works well indoors, especially in multi-floor buildings. The majority of users won’t be connecting with anything higher gain anyway, so it’s a good match.

Meraki has provided some estimated ranges for the Meraki Mini with the stock 2dBi antenna:

D.I.Y. Outdoor Meraki Mini PDF Print E-mail

Through experimentation we have discovered that you can convert an indoor meraki mini to an outdoor unit with some additional parts and a bit of work.

There are now at least three of these outdoor Meraki Minis in use, one is sheltered under an overhang and two are out in the open, pictures can be found in the photo gallery.

Meraki Mini PDF Print E-mail

Equipment from Meraki Networks was selected for its low cost, zero end user configuration, back-end management system and most importantly, its wireless mesh capabilities. This allows for several advantages.

First, bandwidth usage is controlled, so one user doesn’t saturate any one Internet connection. Second, remote monitoring and management allows us to get an idea of network health/usage and modify configuration remotely. Third, as opposed to traditional wireless networks, which require an Internet connection at every access point, Meraki Mini repeaters can relay data as many times needed until it reaches an Internet connected access point (gateway), significantly reducing the cost of building the network.
