- Savings on matches: we analyze errors in the construction of networks of telecom operators
Sometimes it’s better to learn from other people's mistakes, so we made a list of the most common ways to “shoot yourself in the foot” when deploying a network. We are talking about approaches to redundancy, monitoring and building an architecture that will work like a time bomb. All the cases described are real and based on the experience of colleagues in the workshop.
- E-SIM - evil or panacea?
The technology became mass in 2016, but not in Russia. There was no regulatory framework and related technology platforms.

- How to improve the quality of IPTV for customers
We are talking about two technologies that increase customer loyalty to the IPTV provider - Quality of Service (QoS) and Electronic Program Guide (EPG).

Two years ago, the FCC abolished net neutrality in the United States. This is a concept according to which Internet service providers cannot block access to sites and give priority to any type of content. Around the same time, large IT companies and politicians began a struggle to restore net neutrality. Recently, they won a small victory - the court allowed the states to return network neutrality on their territory. In the material we tell what will happen next and who is already introducing, introducing relevant bills.
