Our LTE Live project is underway and we’re excited to share with you some actual project details as we build this private LTE network. Redline is currently working on several iLTE™ projects, so we’re able to show you real data as we go.

Follow the posts below to track our progress and learn what it takes to build an LTE network. We won’t give away all our secrets, or who the customer is, but because it’s a Redline network you know it’s rugged and reliable.

Don’t forget to follow us on social media to see more pictures of the day-to-day build.

 

 

Customer and Partner Training |Oct 06, 2017

Our LTE Live project is well underway; we’ve completed the schedule, RF Plan, and overall network design. We still have much to do, but the highlights of what remain include:

  1. Training
  2. Configuration & FAT
  3. Installation & SAT
  4. Signoff & network hand over
  5. Training is important on any system, but it is even more vital to the success of an industrial iLTE™ mobility deployment. As a solutions-focused company, we are pleased to be working on this project with a key partner, as well as the end customer. Almost all of the customers and partners we’ve engaged have never deployed a full LTE network from end-to-end. LTE is more involved than a typical broadband wireless network, as it includes an Evolved Packet Core (EPC) which is the “brain” that manages authentication, mobility handoff of the User Equipment (UE’s) between eNodeB’s, routing, and much more. In addition, LTE is a Layer 3 network, whereas typical broadband networks are Layer 2. This difference requires a slightly different approach to planning out the overall wireless network architecture.

    At this point in the project we have provided two training courses:

    1. The first course, RSCA RDL-6000, was primarily focused on proper installation practices and alignment procedures. The training was delivered to our partner and customer, responsible for the installation of the radios.

    2. The second course, RSCP RDL-6000, was a comprehensive training on the installation, configuration, and maintenance of the overall solution including the EPC, ENodeB’s, and LTE User Equipment.

    The training was divided into two modules as the riggers and people responsible for the tower gear do not necessarily need to be aware of all the configuration and network software architecture details. The division of the two courses made the most efficient use of everyone’s time on the project.

Network Architecture and RF Planning |Sep 25, 2017

This is the second installment in our LTE Live email series. Feel free to forward this message to any associates you think may be interested.

We’ve kicked off our project and we have our schedule, which provides you with an overview of the scope without compromising the privacy of our customer. Redline, and one of our key partners,are delivering this LTE network for mobile assets that travel anywhere from a few miles per hour to 60 miles per hour. Likewise, the network is also going to be used for personal devices, such as tablets, handsets, etc.

We’ve completed the RF plan and, as in any wireless project, it is essential this is done properly or the reliability, throughput, capacity, and tower locations and device performance can all be impacted. It is even more critical when LTE true mobility is required as the handoffs of the devices must occur seamlessly. At a very high-level, the following approach was used with the RF planning process:

  1. Application capacity and throughput was analyzed for average and peak data rates
  2. Based on application requirements, a 10+10 MHz UL/DL channel size was determined to provide sufficient throughput capacity
  3. Tower heights and optimal locations were calculated based on the Redline eNB and ntenna characteristics, 1 meter LIDAR data, and the antenna height of each vehicle and devices people may be
  4. Fade margins for the Redline LTE coverage was designed for 99.99% availability and based on the ITU-R P.530-13 model
  5. Tower location was determined based on tower location possibilities, optimal RF coverage, and validating the coverage and MCS for each vehicle antenna type and height
  6. With the optimal tower locations the RF plan for the Mircowave Backhaul was completed
  7. A 60% Fresnel Zone clearance was used and the ITU-R P.530-13 model to ensure a link availability of 99.99%

Project Kick Off - Time to Plan |Sep 14, 2017

In our LTE Live project series we started by telling you a bit about Redline’s LTE products and services. We are excited to have started this iLTE™ project and to share actual project details with you as we build this private LTE network. This is one of several LTE projects we are currently working on, and to respect our customer’s privacy, we will be using actual project data, but we will be removing any identifying customer information. This is the real deal.

The embedded image shows the high-level project phases. Some key differences we want to highlight in the LTE project plan vs. a typical PTP or PMP broadband project are:

  1. LTE is a layer 3 technology, instead of layer 2, and therefore network integration planning at the IP level is necessary
  2. LTE is mobility and the RF plan needs to overlap accordingly and drive tests are required to test the mobility
  3. Staging requires an EPC core (the LTE network brain) and rather than just getting a network up and running the LTE EPC core must authenticate wireless users, control handoff, handle security, and ultimately routes the network traffic and integrates it into the plant network
  4. Instead of installing PTP or PTMP radios we are of course installing eNodeB’s which are radios that enable LTE user equipment to connect to the network and do so while moving
  5. And of course SIM cards must be programmed by Redline, interoperable LTE devices must be tested on the network against our eNodeBs
