Top 10: Women in Telecommunications

While much progress has been made with diversity, equality and inclusion (DE&I) initiatives in the industry, telecommunications companies can always do more.
Improvements can be made when it comes to getting women into telco and networking sectors, particularly in leadership and executive-level positions. According to techUK, 19% of the UK telecoms workforce was female in 2020, compared to 37% of the global telecoms workforce in 2022.
Mobile Magazine showcases some of the leading women currently working across the industry to not only spearhead the next generation of connectivity, but who are also championing equality programmes for the future of their business.
