The selection and adoption of the most appropriate connectivity solution are essential, and the connectivity choice significantly impacts the future success of your IoT solutions and the capacity of that innovative device to deliver for end users.

IoT Connectivity & Embedded Connectivity

Today the choice of IoT connectivity and embedded connectivity options is broad and growing. Cellular networks, Wi-Fi, Bluetooth, and more each offer their own advantages and drawbacks. Navigating those options takes experience and skill, and this is where Witekio adds enormous value.

Our teams understand that there can be tensions between the technical requirements for a project, the commercial requirements of the project and the vendor’s business, and the scaling and platform requirements, including the need for machine-to-machine connectivity or Cloud in some cases. They will advise on the best choice for you and then work with you to select the best technologies to support that choice.

Connectivity is critical for every embedded software and IoT solution project.
Connectivity Dilemma?

We are Your Connectivity Experts

Every year our engineering teams work on hundreds of IoT, embedded, and mobile device projects that demand varying levels of connectivity. They understand that the connectivity choice is crucial and that each vendor has different expectations for their product, different constraints from stakeholders, and different demands from end-users. What’s more, cloud-connected devices open themselves to future development and updates driven by data insights, remote monitoring, and the capacity to push updates for maintenance and functionality.


IoT Connectivity

There is one IoT connectivity option that can serve all IoT vendors or address all IoT use cases. Wi-Fi IoT may offer advantages that 5G IoT cannot, and low energy Bluetooth might be the best connectivity option for one of your devices despite the others on your platform relying on an LPWAN, Lora, Sigfox, 3G, or 4G cellular connections. Our experts help you choose the right connectivity option for the right device, guiding you to the best outcome for you and your end-users.


Embedded Connectivity

A variety of application layer protocols exist for embedded connectivity and our teams are experts in navigating them all. Whether common web (HTTP and HTTPS), email (SMTP), or file transfers (FTP), network protocols that include SNTP and SNMP, or even DNS and DHCP, our engineers are able to ensure that the correct protocols are programmed into your device’s embedded software to enable the connectivity that you demand.

Witekio has the connectivity solution and expertise for every IoT project

Our expert engineers consider a variety of concerns, constraints, and capacities in assessing your Embedded connectivity and IoT connectivity requirements and making their recommendations. Among the most important are the ten considerations below:

Outdoor and Indoor Coverage/Range 

IoT and embedded devices demand different connectivity coverages depending on their typical deployment and use cases. Bluetooth Low Energy Android offers a connectivity range measured in meters, while a proprietary LPWA like SigFox or Lora can see range extended to more than 15 kilometers.

Energy Efficiency

Certain connectivity options draw more power and are less energy-efficient than others. Mesh-connected devices running ZigBee 3.0 or similar are far less energy efficient than LoRa, and 2G cellular connections are far more energy-efficient than competing 3G, 4G, and 5G cellular options.

Uplink Data Rate

The speed and capacity of a data connection can be essential to the success of an IoT or embedded project, but the demands of that project can vary. Sometimes an NB-IoT connection with a data uplink rate of just 20kbps is sufficient, while other projects may demand bandwidth in the range of 5G IoT connections of up to 2 Gbps.


Most connectivity options allow for bidirectional communication, however, there are some limitations with regards to SigFox, where the downlink can be limited, and LoRa, where bidirectionality is only offered in Class A.


Some connectivity options are better suited to deployment in a mobile device. Where mobility is an advantage or where it is essential, options such as traditional cellular (2G, 3G, 4G) or LTE-M can be good choices. Where it is less important, though, Bluetooth Low Energy is often a preferred choice.


Localization Options

Where devices demand localization services – for example, relying on GPS or GLONASS coordinates – certain connectivity options offer better functionality. Cellular technologies (2G to 5G) are strong here, as are short-range connectivity options such as Wi-Fi Low Power, or Bluetooth Low Energy.

Quality of Service

The reliability and quality of service can vary significantly, and the quantity and type of data being transferred from the device to the cloud can and will impact the connectivity choice. Cellular networks are typically superior to short-range connectivity options (Bluetooth IoT, Wifi IoT Relay), which in turn are superior to some proprietary LPWAN options, depending on the device and the use case, of course.


While security is always an important concern, greater connectivity security usually also comes with a demand for more processing power and energy use. It’s a trade-off, and it’s why some connectivity options, including LPWAN options, offer only basic security while IoT devices connected to Wi-Fi can employ more advanced encryption.

Connectivity-Related OPEX

Besides the cost of the connectivity hardware (CAPEX) the ongoing costs of connectivity (OPEX) are an important consideration. As cellular technologies expand in capacity their cost increases (3G is significantly less expensive than 5G, for example) while SigFox or LoRacosts are low in comparison.



Traditional cellular and proprietary LPWAN connectivity options lend themselves to scaling and platforming. Short-range connectivity options, on the other hand, when deployed alone offer far fewer options to scale as an ecosystem.
