Using Baicells LTE L2 Mode

Baicells LTE provides an L2 mode to bridge the UE’s.  To change LGW mode, navigate to the Network -> LGW page. In LGW L2 mode, the eNB will create a virtual interface for every UE that attaches. Each virtual interface will then do a DHCP request and create a 1:1 mapping between the UE IP (from Cloud EPC) and LGW IP. In L2 mode, the MAC address that the CPE uses is generated from the IMSI number. To calculate the CPE Mac address, convert the last 12 digits of the IMSI number to hex, then prefix it with 8A. For example, if the IMSI is 311980000002918, you would take the last 12 digits “980000002918” and convert it to hex which would equal “E42C8D5366”, which brings us to the MAC address of 8A:E4:2C:8D:53:66. Once you know the MAC address, you can provision your networking accordingly.

Note:

About the LGW, the CPEs will get private IPs from the cloud EPC. Since the operator has no control over this, LGW is used to translate the IPs to match your own network. You can find some more details on this in the Nova LGW User Guide. We currently do not support VLANs using LGW. With LGW, your options are: NAT mode (L3 w/ NAT), where all CPEs will share the same IP address as the eNB, or Router mode (L3), where you can route to the LGW subnet.

To access the CPE remotely.
First, you have to do some settings on eNB and CPE before you can access into the CPE remotely.

From base station web GUI:
Under LTE Settings->LGW Settings, you can select either NAT (default) or Router mode. Under either mode, you can remotely access the CPE. Details of which are included in the attached LGW User Guide. Also, as described in this guide, you can statically assign an IP address to each CPE based on the SIM card’s IMSI number.

From CPE web GUI:
To enable remote access to the CPE, please remember to enable the “Allow HTTPS Login from WAN” parameter on the System->Web Setting page.

One Reason IPV6 on MikroTik Doesn’t Stink

One word, auto configuration.  That’s two words, ok, but if you scrunch it together it is one, autoconfiguration.  My spell check keeps complaining about making it one but oh well.  In the MikroTik world, enabling the MikroTik IPv6 package is really all you need to do to start using it (provided your computer is dual stacked as well).  Today, I realized how nice it is to take a router, reset to factory defaults, and as long as IPv6 is enabled, I can log into the router, Layer 3 with no configuration because IPv6 autoconfigures itself.

That is a big deal because often times on certain laptops, I can’t get MAC WInbox to work.  It can be really flaky but with IPv6 I don’t need it.

Example: I reset this router to factory defaults and look at Winbox:

I can click the MAC address (green arrow) and put up with disconnects or failed connections or click the red arrow and have instant Layer 3 access with no configuration on the router. This one benefit is enough for me to start running IPv6. Obviously, there are many others but this should get your attention at least.

If you want to start learning IPv6, watch some YouTube videos, there are tons, and then create a free IPv6 tunnel with Hurricane Elecric’s Tunnelbroker.com.  Try it, it works!

Updating PoE Standards on the UniFi Product line

Ubiquiti posted this recently and I thought it worth repeating.

UniFi Access Points have always been built to be powered by PoE – it’s convenient, easy to setup and scalable. When we first started producing UniFi nearly 7 years ago, 24v Passive PoE was the standard in the operator space so we opted to use 24v passive for our Enterprise lines (UniFi, EdgeMAX).

UniFi Access Points have always been built to be powered by PoE – it’s convenient, easy to setup and scalable. When we first started producing UniFi nearly 7 years ago, 24v Passive PoE was the standard in the operator space so we opted to use 24v passive for our Enterprise lines (UniFi, EdgeMAX).

Since then, 802.3af and 802.3at PoE technologies have become the standard, especially in the Enterprise space. The 802.3af/at standards provide a number of benefits over 24v passive that improve stability, allow for greater voltage, etc. (For more details on PoE methods/standards see our article on PoE here).

For this reason, we have been intentionally moving our products (UniFi APs, UniFi Switch, UniFi Video, etc.) toward the current standard for some time, and will continue to do so.

  • 802.3af+24V Support for UAP-AC-LR/UAP-AC-LITE
  • Removal of 24V Support from New Production of UniFi Switch Series

While we have produced many devices that support 802.3af/at, a couple of our Access Points (UAP-AC-LITE, UAP-AC-LR) continued supporting only 24V passive. Over the past several months (starting in September 2016) a number of customers have noted the appearance of some UAP-AC-LRs/UAP-AC-LITEs that have a sticker showing “802.3af Compatible” (see top-left of boxes in image below):

This reflects a hardware revision that has been made to make newer UAP-AC-LITEs and UAP-AC-LRs 802.3af compatible in addition to supporting 24V passive. Any device produced with datecode 1638 (September 2016) and up contains this revision and can be powered by any 802.3af power source like the UniFi Switch.

As a part of updating and improving our products, we will continue to transition away from 24V passive PoE and prioritizing 802.af/at standards. To this end, already-produced switch units with 24V PoE support will retain it, while all future production starting on July 1st 2017 will be 802.3af/at only (across all UniFi Switch models). As existing stock at distributors/resellers/etc. will remain 24V+802.3af stock for some time (until it sells out), this transition will be gradual, with our goal of simplifying UniFi PoE to standards.

This update to the UAP-AC-LR/LITE has been made to ensure that these devices can continue to benefit from updated technology and be deployed with industry standard PoE.

AC-LITE and AC-LR Change Summary

  • The only change made to the AC-LITE and AC-LR devices was the introduction of 802.3af compatibility, as of September 2016.
  • This will not affect the performance of the devices in any way.
  • This modification was added to add stability/consistency to product line at no additional cost to customers.
  • These updated devices will continue to permit 24V passive.

UniFi Switch Change Summary

  • The only change made to the UniFi Switch series is the removal of 24V output support.  Models with 24V support removed will start production July 2017:
    – US-8-150W
    – US-16-150W
    – US-24-250W
    – US-24-500W
    – US-48-500W
    – US-48-750W
  • All new UniFi Switch models will also not have 24V support.

This transition is by popular request of UniFi users.  We intentionally rolled 802.3af support into the UAP-AC-LITE and UAP-AC-LR (starting Sept. 2016) nine months before initiating removal of 24V from new production of the UniFi Switches (starting July 2017) to lessen the impact of the transition.

MikroTik Optimal Wireless Config for Transparent Point to Point or Backhaul

I am often asked what is the optimal configuration for a point to point with Mikrotik, typically SXT’s.  I would stress that the fewer settings you make, the better the link will work so I don’t recommend tweaking, just set the basics.  Here are screen shots of everything that needs to be set to make a high capacity point to point.  The red boxes are settings that are peculiar to that end of the link and the blue boxes are the settings that must match both ends of the link:

Getting Started With Baicells LTE

Baicells has created a new “LTE How To” for new WISP operators.  As you may already know, Baicells equipment is Plug & Play and by far the easiest LTE devices to set up and add to your current network. Many common startup problems evolve from the operator making too many changes during startup. Keep it simple to start with and tweak settings after the system is live.

The new guide can be found HERE.

One thing you will notice in the guide is that the simplicity of the product is enhanced by the fact that UE’s (CPE devices) and eNodeB’s (Base Stations) must be associated with the new owner’s CloudCore account to operate.   ISP Supplies is the only distributor that automates that process through our custom application, SIMPro. SIMPro allows us to scan the serial numbers of eNodeB’s and the IMSI’s of UE Sim Cards into our database, tie them to your SIMPro account and automatically email them to Baicells for provisioning.  You can even add notes to the devices in the SimPro app.  When your product arrives, it is ready to deploy.

Baicells LTE SimPro

LTE is the future of fixed wireless and you can learn more on my blog.

ISP Supplies is one of the largest Baicells LTE distributors in North America with hundreds of successful LTE deployments.  Our knowledgeable sales engineers are standing by to assist you in designing and deploying LTE in your existing or startup network.  For access to SimPro or to discuss fixed LTE, call us today at 855-947-7776.

MikroTik Automatic Failover Two Gateways

There’s a million ways to do this on the wiki and the web but none of them fit my particular application.  Let me explain:

1.  The weak point in my network was an AirFiber 24 upstream from the tower I am connected to wirelessly.  This is the link that goes down in heavy rain causing an outage at our office to PROVIDER1.  We have a backup connection through a second provider that is slower but being 5GHz doesn’t drop in the rain, PROVIDER2.

The network is like this:

[MikroTik CCR1036-12G-4S]
—[RBSXT]—[RBOmniTikU-5HnD[—[AF24]—[PROVIDER1]
—[RBSXT]—[PROVIDER2]

2. Simple floating static routes with check gateway doesn’t help because on PROVIDER1 we never drop our 5GHz connection to the tower, it’s the upstream link that fails.

3. I tried recursive routes and it works but the failover was still lacking and seemed sporadic at best.

4. When failover did occur, the VOIP PBX would hold the connection open through the dead provider and some phones in the office wouldn’t work at all, rebooting the phone was the only solution. We tried a ton of solutions and never got it to work consistently.

The solution that works the best is as follows.  I am using a combination of static routes, firewall rules and Netwatch scripts. Here it is:

The Netwatch script watches 4.2.2.4 (a public DNS server). If it goes down:

  • It changes the distance on the default router to PROVIDER1 to 20 making it inactive.  Now all traffic defaults through PROVIDER2.
  • It emails me that the gateway has changed. Please not you must set up your email server IP, and any authentication in /tools e-mail first.
  • It clears any connections to my VOIP gateway, thereby causing them to re-establish, interestingly calls do not drop!
  • When pings return, it sets the distance on the default route through PROVIDER2 back to 1 making it the active route and then clears all connections to the VOIP gateway again.
/tool netwatch
add comment=CheckCon down-script="/ip route set [find comment=\"\
    PROVIDER1\"] distance=20\r\
    \n/ip route set [find comment=\"PROVIDER2\"] disabled=no\r\
    \n/tool e-mail send to=\"YourEmailAddress\" body=\
    \"Connection with PROVIDER1 Lost, Switched to PROVIDER2\" \
    subject=\
    \"Lost connection with PROVIDER1\"\r\
    \n/ ip firewall connection remove [find dst-address=\"\
    YourVoipGatewayIP\"]" host=4.2.2.4 interval=5s timeout=2s \
    up-script="/ip route set [find comment=\"PROVIDER1\"] distan\
    ce=1\r\
    \n/ip route set [find comment=\"PROVIDER2\"] disabled=no\r\
    \n/tool e-mail send to=\"YourEmailAddress\" body=\
    \"Connection with PROVIDER1 Regained, Switched back to PROV\
    IDER1\" subject=\"Regained connection with PROVIDER1\"\r\
    \n/ip firewall connection remove [find dst-address=\"\
    YourVOIPGatewayIP\"]"

Next we need to ensure we can only ping our test host through the PROVIDER1 connection.  This is done with a static route through PROVIDER1:

/ip route add 
comment="Force test pings through PROVIDER1" dst-address=4.2.2.4 /
gateway=199.21.228.153

Next we need to comment our default routes.

/ip route
add comment=PROVIDER1 distance=1 gateway=199.21.228.137 scope=\
    11
add comment=PROVIDER2 distance=10 gateway=209.112.225.65

Next we need to ensure that no pings to our test ip go through PROVIDER1 only:

/ip firewall filter add chain=output comment=/
"Drop pings to 4.2.2.4 if they go through PROVIDER2" \
dst-address=4.2.2.4out-interface=ether2 action=drop

As I write this it is pouring rain outside and I have observed it go down 3-4 times and even with people on the phone, calls continue and we haven’t lost the network. I am loving this!

What can I do if my wireless devices don’t roam between my wireless AP’s?

Good question, one I was also asking myself when I set up a large Mikrotik CAPsMAN network. A moving laptop would hang onto a -85 signal when a -70 was available.  It did not make sense.  So, after some research I found some ideas to help you.

When you are walking between access points (assuming they have the same wireless SSID name and same security), you may find that your wireless client, that is your laptop like a mobile phone is still sticking to the distant device and will not roam to the nearest device.

How roaming works:

Roaming is purely a client decision. The wireless client is responsible for deciding it needs to roam, and then detecting, evaluating, and roaming to an alternative AP. WLAN standards bodies (such as IEEE) and industry bodies (such as Wi-Fi Alliance) do not specify when a client should roam, or how the client roams.

So, roaming or not roaming, it is totally decided by your wireless client’s roaming algorithm. Different wireless client vendors’ roaming algorithms are also different and are not generally published.

Resolution:

There is no role played by AP in this client roaming process. So, your best option is to configure your wireless client to achieve fast roaming for you.  Some NIC vendors give some mechanism to control this roaming behavior, specifically Intel.

PC Users

In Intel, it is known as roaming aggressiveness and this setting allows you to define how aggressively your Wi-Fi client roams to improve wireless connection.

Here are the configuration methods on Intel WNIC:

You can go to control panel -> network and internet -> network connection and choose the wireless connection. Right click the wireless connection and choose properties. Click configure and choose Advanced and choose roaming aggressiveness.  Typically there are 5 options. Here are the explanations of these five options:

Lowest: Your wireless client will not roam. Only significant link quality degradation causes it to roam to another access point.

  • Medium-Low/Medium-High: Allow Roaming.
  • Medium: Balanced setting between not roaming and performance.
  • Highest: Your Wi-Fi client continuously tracks the link quality. If any degradation occurs, it tries to find and roam to a better access point.

Mac Users

It is still possible on the Mac, just not as elegant.  Open a terminal window and type the following command all on one line then Enter.  You will need the administrator password of course since this has to run as the root user:

sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport prefs joinMode=Strongest

This should get your device to drop a weak AP when a stronger signal is available. This will work with any AP setup, Ubiquiti, MikroTik, etc.  Happy roaming!

“WISPatizing” LTE

This is a letter from Patrick Leary at Telrad, I thought worth sharing.

We all know LTE has first been created for the needs of giant mobile operators first. That means the LTE enhanced packet core (called the EPC in LTE-speak) includes a host of features fixed operators may NEVER need, like translating diverse 3G backends into a standardized LTE core. Who wants to pay for that? Not me and certainly not you. As well, being mobile centric first, LTE out of the box EXCLUDES certain things fixed operators like and use, such as Layer 2 services.

Being the first and so far ONLY company out there in the LTE space mainly focused on the fixed space, Telrad is the tip of the spear trying to innovate and idealize the solution for WISPs and other local and regional fixed-focused operators. It has been a struggle. EPC are things that can run deep into 6 figures and we had to find a way for the economics to make sense for your models.

Complicating this, because we use an SDR platform, Telrad is able to do something no other vendor on the planet has done: offer the EPC as a hardware-less, software feature EMBEDDED into each base station as an option. That’s super cool, meaning smaller operators won’t need to shell out for a full centralized EPC. But, that also means we’ve made our lives more difficult because options are another SKU to manage.

We now think we’ve got it as refined as possible and here’s the key to what we’ve done:

Dividing up the EPC functionality to allow for operators to purchase ONLY the features you need, and allowing that granularity to be applied to EITHER the embedded or the centralized EPC models.

So what’s been made granular (and priced much smaller per function)? These are things that in the traditional LTE world are often found as individual appliances. Our centralized core can include them all in one appliance for 1/10th or less of what traditional EPCs can cost. Now we’ve even made it MUCH more affordable than even that, by taking the subsets of EPC functionality and providing them as distinct SOFT modules that can be purchased ala carte into either the embedded or centralized Telrad EPCs. Here are examples:

– Don’t want AAA or need Radius? Fine. We now have a feature called iHSS, which allows MAC level authentication.

– Want to use your Radius, but NOT use our implementation? Don’t get iHSS. Instead get the IWK module, which enables internetworking with an external Radius AAA server.

– Planning ONLY to do best effort or apply a single policy across all subscribers? Fine, no need to have the PCRF functionality of an EPC.

– Want to implement distinct and varied service flows and other QoS services? We’ll offer iPCRF as a module.

These are examples. If you used all the functionality, it would still not cost you any more than how things were first initially priced, even if purchased in pieces, so there is no nickel and diming. The difference is, if you need LESS, you’ll be investing less.

Those of you with firm LTE quotes on the table? We’ll need to revisit them, as the numbers will drop. Those with only estimates at this point? That’s worst case and we’ll get you revisions as you get nearer to pulling the trigger.

One last thing….and it is another big one. With LTE comes the entirely new NMS. Better, lighter, simpler, less cost. I’ll be doing another mail on that as soon as I can.
