Implementation Best practices for PTT Over LTE Solutions

Posted on 2017-11-02 by Daniel Hackl

Though undergoing digital transformation in various areas of your business can be a daunting endeavour, the silver lining is that implementing new software technologies is relatively low risk. Historically, it would have been very expensive, and a lengthy process to deliver a highly functional technology solution that customers would actually want to use. Now, not only is the cost of delivering high-end IT solutions decreasing all the time, the execution can be achieved fairly quickly; sometimes in a matter of months or even weeks.

The same logic applies to PTT over LTE. It is highly scalable and initial investments are minimal if the solution is delivered “in the cloud”. Providers can be switched on a monthly basis if needed, should a new PTT application provide a more suitable feature set than the previous one. Investments would come mostly from OPEX with smaller portions coming from CAPEX.

Operating Expenditures (OPEX):

  • Includes subscription fee for PTT applications and mobile phone data plan.
  • The mobile phone might also be included in the mobile phone data plan package.

Capital Expenditures (CAPEX):

  • Can include the mobile phone as well as accessories but there are also options to finance them and have them allocated in OPEX.

Rolling Out Your PTT Over LTE Transition Project

It is very easy to ramp up a PTT over LTE project starting with an initial trial of 10 people in a specific group and then rolling it out little by little to more users.

Most PTT applications offer a bridge to enable radio users to communicate to PTT over LTE and vice versa. For companies only on radio networks this offers an opportunity to assess and identify what users should transition to PTT over LTE, which users would use both radios and PTT over LTE, and which users would remain using only radio.

Inclusion of Project Stakeholders

It is very important to include other stakeholders within the organization in the project to collect requirements and attain feedback as any change will find some resistance. These groups might be responsible for safety, security including IT security, worker union rights and depending on the investment, the board of directors or C-suite members like the CFO, and of course, the users themselves. As a basic solution requirement, communication should be maintained as before with some reduction to costs. If this can be fulfilled, a lot has been accomplished. Other benefits like increasing simplicity and safety of communication, better information distribution, more information collection to make better decisions are value added benefits. What should be avoided is the mentality that the new solution will solve all the issues the old solution had plus provide all kinds of additional benefits. Having unrealistic expectations can lead to scope creep and a significant delay to the project timing.
