VoLTE – Now We’re Talking

Posted by Erik Lilieholm on April 18, 2017
At the time when cellular was synonymous with voice calling, both handsets and networks were built and optimized for the purpose of talking and listening. While great strides have been taken in technology and network deployment to satiate our appetite for mobile data, voice has received relatively less attention. By migrating voice service to LTE, additional spectrum can be carved from 2G/3G and these older technologies eventually retired. Erik Lilieholm explains more in this blog post and the updated “LTE Best Practices” eBook.

CommScope Definitions: What Is Network Densification?

Posted by Erik Lilieholm on December 11, 2015
Network densification is a way for wireless operators to add more capacity to their networks by adding more cell sites. Increasing density in the data center and enterprise industries is about increasing the available resources without having to acquire more rack space. In today’s CommScope Definitions blog post, Erik Lilieholm further explains the term “network densification."

The Cost of Noise and the Value of Silence

Hiding in Plain Sight: The Secret about Interference Mitigation Filters

Posted by Erik Lilieholm on March 23, 2015
Did you know that an interference mitigation filter (IMF) is pretty good at hiding in plain sight? Thanks to the powerful modeling software available today, an experienced designer can create almost any desired filter function that can be realized. A multitude of RF conditioning products can incorporate filters with different functions without you even realizing it. Erik Lilieholm explains more in today’s blog post.

Buyer’s Remorse

Posted by Erik Lilieholm on November 27, 2013
With the holiday shopping season upon us, Erik Lilieholm writes about how CommScope can help you avoid buyer’s remorse – at least in terms of purchasing RF diplexers. The new line of UltraBand diplexers covers an ultra wide range of frequencies, supporting spectrum used now and possibly in the future. This wide range should help customers adapt to future spectrum needs more easily…and hopefully avoid buyer’s remorse today.

You Say Tomato...
