Cambium PTP550 Data Rates

Some info on the cambium PTP 550 Data Rates

“Downlink Max Rate” specifies the maximum downlink MCS value that the Rate Adapt algorithm will choose.
MCS values range for data from MCS 9 to MCS 1 for one or two Spatial Streams (Single Stream and Dual Stream respectively). A higher MCS value (e.g. MCS 9) carries more data, but requires more link budget / stronger radio signal. Thus, MCS 9 provides the most data, but the least robust link (i.e. greatest chance data can be lost) and MCS 1 provides the least data, but the most robust link (i.e. least change data can be lost).
DS MCS provide two streams of independent data over the two transmit chains while SS MCS provide one stream of data over both transmit chains.
Setting “Uplink Max Rate” to a DS MCS 9 – DS MCS 1 value will allow this MCS and all lower dual stream MCS values to be used along with all similar or lower single stream MCS values. For example, choosing DS MCS 8 means that DS MCS 8 – DS MCS 1 and SS MCS 8 – SS MCS 1 will be used in the Rate Adapt algorithm. Setting “Uplink Max Rate” to an SS MCS 7 – SS MCS 1 value will allow this and all lower single stream MCS values.

Lab Network

I am starting an ongoing series involving a semi-static set of devices.  These will involve different tutorials on things such as OSPF, cambium configuration, vlans, and other topics.  Below is the general topology I will use for this lab network.  As things progress I will be able to swap different manufacturers and device models into this scenario without changing the overall topology.  We may add a device or two here and there, but overall this basic setup will remain the same.  This will allow you to see how different things are configured in the same environment without changing the overall scheme too much.

We will start with very basic steps.  How to login to the router, how to set an IP address, then we will move to setting up a wireless bridge between the two routers.  Once we have that done we will move onto setting up OSPF to enable dynamic routing.  After that the topics are open.  I have things like BGP planned, and some other things. If there is anything you would like to see please let me know.

ePMP elevate webinar

Some highlights on the ePMP Elevate platform.

-Allows ePMP Elevate software to run on on non-Cambium 802.11n subscriber modules
-ePMP Elevate subscribers function as ePMP subscribers
-Solution for WISPs who have hardware deployed. Offers a migration plan.
-ePMP AP must be licensed for ePMP Elevate
-5GHZ Only
-XW and XM based Ubiquiti hardware
-17 supported models
-2.4 GHZ is in on the roadmap. No official comment on timeframe.
-cnMaestro support is available for XW hardware
-Replaces the UBNT software with a cambium interface. Looks pretty close to any other ePMP interface.
-If DFS is FCC certified on the hardware it will work on the hardware when it gets the elevate system.

ePMP 100 version 2.4 released

New Features added:

Release 2.4 adds the following features:

eFortify™ Enhancements:

  • New ePTP mode operation: The release introduces a new mode of operation for point-to-point configuration providing significantly lower latency than other modes. Not available for DFS bands.
  • Improvements to VoIP performance
  • Ability to configure the Max MCS independently in each direction

eCommand™ Enhancements:

  • eAlign: The release introduces eAlign (found under the Tools menu), a tool to aid with link alignment
  • Session Time per SM on the AP (under Monitor->Wireless)
  • Improvements to the throughput chart on the GUI dashboard (under “Home”) 

ePMP Version 2.3.1 released

PDF Release notes can be found at http://community.cambiumnetworks.com/t5/ePMP-1000/New-ePMP-Release-2-3-1-now-available/m-p/37067#U37067

Highlights Include:
o RFC1213 supports standard interface MIBs. Items such as Ethernet interface Tx/Rx and
corresponding stats are now supported per the standard RFC. This allows users to utilize 3rd party monitoring tools that support RFC1213
Separate Management IP when SM is in NAT mode
o Separate Wireless Management IP will provide the ability to separate management traffic from user traffic when the SM is configured in NAT mode providing separate management access to the SM. This includes the ability to have a separate management interface when PPPoE is enabled on the SM.
ARP table display
o Displays all the ARP entries for interfaces present in the routing table
VoIP helper functionality under NAT
o When the SM is in NAT mode, ePMP inspects SDP packets and automatically creates appropriate
