India s networking market which includes ethernet switch, routers, and WLAN (wireless local area network) segments witnessed a 16.4 per cent year-over-year (YoY) decline in the third quarter of this year due to the negative impact of Covid-19, industry tracker International Data Corporation (IDC) said on Thursday. The decline during the July-September period was majorly characterised by the decline in router revenues.

The WLAN market in India grew marginally by 3.1 per cent YoY.
