Cambium Roadshow 2018 Morning Session

Recently I attended the Cambium Roadshow 2018. Some notes.

-Epmp 3000 expected to be here in September.  4×4 Mimo product. Early marketing should be coming in the next couple of weeks.
-820C pricing is getting aggressive.
-Mikrotik Open beta Elevate is out.  Ability to elevate Mikrotik units.

Force 300
-second radio can be used as management access or a realtime spectrum analyzer
-No more java client for the analyzer
-65k packets per second
-About 10% throughput at the sector in a legacy network.  Future software updates can lessen this.
-Dynamic spectrum capability
-Future vision is to have CNMaestro be aware of spectrum. This opens up the ability to view channels and interference on a network level.

450 Product Line
-Channel sizes have increased to 30 and 40mhz
-450b radios Integrated (17dBi for $299) and high gain (24dBi for $349)
-New processor
-4.9-5.925 GHZ
-Single gigabit port
-30 volt power supply, polarity Agnostic
-450 3.65 will be SaS compliant

cnArcher
-iPhone app should be here soon.
-Ability to push configs from the App

450M
-8×8 mimo due to physical size. 12×12 or 16×16 would mean a very large product
-Integrated 90 degree sector
-Direct DC power
-SFP port
-Current SMs will connect

Ac Wave 1 vs Wave 2

There has been much discussion on the performance of going from an N Series outdoor wireless system to AC.  Not all AC is created equal.  Right now there is AC Wave 1 and AC Wave 2.  Just about all the AC stuff currently in the pipeline for outdoor wireless is wave 1.  There is wave 2 indoor gear available, but for a WISP you are interested in the outdoor gear.

So what’s the difference?
For some reading about spatial streams, channel sizes, etc. look at this article https://info.hummingbirdnetworks.com/blog/80211ac-wave-2-vs-wave-1-difference

For the WISP folks who want the Cliff Notes version here are some key differences.

-Wave 1 uses 20,40,and 80 Mhz Channels.  Wave 2 can support 80 and 160mhz channels.  The 160mhz channel would be two 80mhz channels bonded together.

-Wave 1 can do 3 spatial streams.  Wave 2 does 4. This requires an additional antenna to take advantage of wave2.  This is a hardware upgrade from wave1 to wave 2.

-Wave 2 supports MU-MIMO. The AP can talk to 4 clients individually at once.  The client must also support this, which is a hardware upgrade from wave 1 to wave 2 on both the client and the AP.

The question to ask your vendors is what is the upgrade path if you are using existing AC gear.  If you are running AC currently you are most assuredly going to have to replace your AP radios and antennas.  Will your existing clients work with the new AC wave 2 aps? An important thing to ask.

 

5.8 Cambium Elevated Devices & Max EIRP

Lately, we have had a few clients run into signals becoming worse when they elevated clients to ePMP.   This is not a result of the software being bad, but it enforcing the max EIRP on the units.  This boils down to older devices compliant with original FCC grants which allowed unlimited EIRP.  The Cambium elevate recognizes the latest grant for the devices.  This grant allows for a max of 41 dBM on 5/10/20 mhz channels and 38dBM on 40mhz.

So if you have elevated some older devices from UBNT your signals may have dropped.  This is due to compliance with the latest rules for the device.   As our industry matures, becoming compliant will become more and more important.  On the UBNT units, newer firmware from UBNT also does this.

Cambium has a forum post on this. http://community.cambiumnetworks.com/t5/ePMP-Elevate/5-8-GHz-Elevated-Devices-Maximum-EIRP-in-the-United-States/m-p/73141#M475

We have some tricks of the trade we can do. Contact MTIN for how we can help.

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.

Pricing
1 Subscriber license $35
10 Subscriber License $315
You would buy multiples 10 subscriber licenses for more than 10 subs.  Locked to wired mac Address of the AP.

 

 

 

 

Cambium Releases ePMP v 2.4.3

Software Release 2.4.3 is now avaialbe. 

The release includes the following updates: 

  • L3 Routing on the SM 
  • Multiple User Login on the GUI 
  • 4.9 GHz support under Country Other 
  • Ability to enable and disable management access on the SM from the Ethernet when Management VLAN is configured 
  • Ability to disable the SM’s primary Ethernet port 
  • Ability to disable factory default through power reset sequence

Performance Enhancements 

  • Improvements to UL Latency enhancing TCP throughput under interference 
  • Improvements to Rate Adapt mechanism in ePTP mode 
  • Memory optimization

Upgrading EPMP GPS Firmware

Beginning with System Release 2.0, users can upgrade the firmware of the on-board GPS chip present on the Connectorized Radio with Sync.

To upgrade the on-board GPS chip on a Connectorized Radio with Sync:
1. Navigate to Monitor => GPS to check the GPS Firmware Version that is currently present on the radio.

2.If the GPS Firmware Version displays AXN_1.51_2801, navigate to Tools => Software Upgrade

3.Under the G P S F i r m w a r e upgrade section, select the same package used to upgrade the device’s firmware ex: ePMP-GPS_Synced-v2.4.2.tar.gz.

4.Click upgrade

5. The upgrade can take up to 3 minutes. Once the upgrade is done, the radio’s UI prompts for a reboot and the reboot button will be highlighted.

6.Click the Reboot button on the top right corner of the UI.

7.Once the radio has completed its reboot process, check under the Monitor => GPS page to check the firmware version
