The communications sector is undergoing a fundamental and rapid evolution, with new digital companies accompanied by challenging long-standing business models, runaway technological development, convergence, disruption and significant change to the regulatory landscape. Deregulation in certain areas is going arm in arm with greater regulatory control in others, such as data breach, consumer privacy and merger.

In face of these challenges, communications businesses need to adapt, diversify into new business lines, and often to grow, whether organically or through acquisition. Additionally they need to understand and comply with the new regulatory requirements.

You need lawyers who understand your sector to tackle these challenges head-on, often on an international basis in this most international of businesses. This is where our international team of sector specialists come into play. We have over 200 experts, many with in-depth experience in the industry, across our 65 offices.

We support communications companies within all aspects of their operations, including acquisitions, data protection network sharing, pricing sales, operations, product development, regulatory compliance, licensing and distribution arrangements, and issues relating to cyber breaches and intellectual property protection.

Their geographic spread globally and in the UK is really useful and makes them quite unique.

Chambers UK, 2015

Our team frequently advises on complex or ground-breaking transactions or issues. In the past year alone, CMS has advised on M&A transactions in the sector with an aggregate value of over EUR 10bn.

Additionally, we advise mobile and fixed line operators on the complex issues around network sharing agreements, helping our clients to realise huge cost saving potential, as well as preparing their business and infrastructure for future technologies and investments.

We have advised on network sharing deals for clients in the UK, Belgium, Germany and several CEE countries, and have also advised on their feasibility in other European countries. This makes us one of the market leaders in that field.

Our dedication to achieving a commercial solution coupled with our understanding of your industry sector, means you can remain focused on your business.

Our Global Head of TMC, Chris Watson, is ranked in Band 1 in Chambers UK 2015 for Telecommunications.
