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.

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.

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.
