Challenges and Considerations for Li-Fi Adoption
Although LiFi is emerging as a budding communication technology with undeniable potential, there are some challenges that might hinder its widespread adoption. These are:
- Line-of-sight communication:
LiFi relies on a direct line-of-sight connection between the light source and receiver in order to transmit data. As a consequence, physical obstacles such as walls, or furniture can obstruct the path of a LiFi signal. This feature limits the connection capabilities of LiFi networks as they are easily disrupted by obstructive objects in the environment. Overcoming this limitation involves the strategic placement of the LiFi transmitter and receptor so that their connection is not hindered due to disorganized surroundings. - Interoperability issues:
As LiFi is still an emerging technology, there is a lack of standardized protocols to govern its development. This means that new LiFi products in the market might face compatibility issues with pre-existing devices. To solve this problem, leading LiFi companies are on their way towards finalizing common manufacturing standards for LiFi devices to smoothen out their adoption in the wider market. Oledcomm has already collaborated with the Homegrid Forum Association to adopt the 802.11b standard for its products, paving the way for better interoperability in the future. - Infrastructural Challenges:
Although LiFi technology is simple to install and deploy, it still requires some small changes in infrastructure to be functional. This includes the installation of transmitters, and AP or antennas to direct signals towards receptive devices. Retrofitting existing infrastructure to establish a LiFi network may require monetary investments for initial setup. So, depending on the scale/size of the project, deployment of LiFi can demand planning, coordination, and investments.
