Smart devices are ever gaining momentum in simplifying work and reducing human intervention. IoT is enabling previously disconnected devices to communicate with others across industries like manufacturing, automotive and utilities.

Felix Omwansa joins us on another episode of the Africa Water and Energy Podcast to highlight the existing IoT network technologies organisations can adopt today. Key discussion points include:

* A brief explanation of IoT* Some of the utility applications supported by IoT today* The roles of a utility, systems integrator and customer in this ecosystem* Common IoT network infrastructures working in East Africa* Selection criteria for IoT networks* Common pitfalls and solutions around using IoT networks in the region

What is IoT and IoT networks?

The Internet of Things (IoT) comprises of devices, machines, objects or equipment with unique identifiers, and that are connected to the internet. People and animals also fall into this definition, as long as their ability to send data over a network does not require human-human or human-computer interaction. These devices, objects or people are what is referred to as ‘things’. 

The infrastructure that enables these devices to communicate with one another is the IoT network

Utility applications supported by IoT

Common use cases include:

* Automatic Meter Reading (AMR) using smart meters* Meter control with prepaid meters* Smart grid meters which facilitate 2-way communication between the utility and the customer

Roles of Utility, System Integrator and Customer

The utility’s role remains to ensure a customer gets the due service. This means that they serve the customer side with billing and supply services. 

The system integrator, in this case, refers to the company or individual implementing smart technologies. This involvement includes either designing, installing or configuring smart meters and other communications infrastructure that support the utility’s core business

NOTE

Cellular networks can also be used to support IoT infrastructure. The common examples are GSM and LTE. Mobile carriers support these networks, though with included network charges. 

Selection criteria for IoT networks

There are 5 key considerations are:

* Range. You should consider how wide the coverage is expected to be. * Data Rate. Evaluate the data bandwidth required by the IoT devices* Power. Are the devices running on mains electricity or they’re battery powered?* Frequency. Consider the limitations of your transmission frequency around obstacles* Security. How secure are your network devices and data?

Common challenges and solutions

* Customer education and awareness are relatively low in the region. IoT companies and enthusiasts should consider communicating their businesses and passion to help inform the market of the existing possibilities. * Cost savings is a key motivator, particularly for Africa-based companies. With the relatively low margins by utility companies, it is therefore important for IoT companies to come up with cost-conscious models that benefit all parties. * The legislation is not well defined for I...
