MD4000 Model Numbering Scheme

Explanation of Model Number Format. Please consult with our tech support staff when defining a custom configuration.

Explanation to Legend (numbers after black boxes refer to number markers above (1,2,3 ..)

1 MD for Mesh Nodes or ME for Mesh Engines (OEM customers only, housing computer board in their own enclosures).
2 Number of available radio slots. Standard board has 4. [Image]
3 The number of radios used in this configuration- could be 2,3 or 4.
4 Frequency band of the Uplink backhaul radio (in slot 0) : 5 for 5.8GHz, 2 for 2.4GHz, 4 for 4.9GHz Public Safely.
5 Model Configuration. Each of the four radio slots may be configured to be uplinks, downlinks, service radio or scanners.

Notes: Meaningful configurations center around the base model 4350: one uplink in slot 0, one downlink in slot 1 and service radio in slot 2. Variations around this base configuration depend on how slot 3 is configured. Slot 3 is reserved for the scanning radio needed in high mobility situations. If it is not a mobility situation, then slot 3 may house an additional downlink (4452) or an additional service radio (4458). If the mesh node has a permanent Ethernet link, then the uplink is not needed: Models 4454 and 4424 support a root node all downlink configuration. Supported configurations are:

{0,2,4} denote the number of backhaul downlinks present. Since there is generally always at least one downlink backhaul
present, 0 is misleading. For legacy reasons, 0 denotes the common case of one backhaul, as in 4350. The most common configuration, Model 4350, has one 2.4GHz service radio in slot 2 and 5.8 GHz uplink and downlink in slots 0,1. Additional downlinks on root nodes enables more bandwidth dispersion from a central Ethernet link. Models 4452 and 4454 support two and four backhaul downlinks respectively.

{5 } denotes a mobility Scanner (the "S" resembles a "5"). A passive listening radio housed in slot 3 provides information needed for the backhaul uplink to switch over to the next best candidate parent mesh node's downlink. Models 4455 and 4325 are four and three radio systems respectively with a scanning radio in slot 3 to ensure the rapid switch over from node to node in high speed mobile scenarios [More]

{8 } Model 4458 supports up to three 2.4GHz or 4.9GHx Access Points (AP) radios service clients with sectored antennas. Two variations are possible, one with one uplink and one downlink and two service radios: Model 4458-AAII. The second variation is where the downlink is not needed- as in edge nodes. In that case three slots are available for sectored antenna access. That configuration is Model 4458-AIII.

6 Frequency band for the uplink radio, in slot 0. Typically A (802.11a) B (802.11b), G (802.11g) or P (Public Safety)
7 Frequency band for the downlink radio, in slot 1. Usually matches uplink but bridging across freq. bands is permitted.
8 Frequency band for the service radio, in slot 2. Generally B (.11b), G (.11g) or I (both b and g).

Notes: These are simply default factory settings. The B, G, I settings may be user modified via the NMS.

9 Frequency band for the service radio, in slot 3. Depends on the radio functionality. If none present, marked with "x".

Note: Please use the MD4000 numbering scheme to discuss your custom configuration with our application engineers. Also note that other options (e.g. GPS, 3.3VDC boards) are not part of the configuration scheme. They are ordered as separate items.
