Philip Sorrells, VP of Strategy Marketing, Wireless, at Commscope, discusses how to avoid noise in LTE and how to monetise the investment in this service.

CommsMEA: What are the solutions that you are implementing to improve LTE performance?

High quality of LTE is the ability to suppress noise and interference in the network. The noise comes from a lot of different areas. The first problem comes from the set of frequency bands that an operator owns. The second problem can happen when you have neighbours who have receivers. These are frequency dependant. The third one is environmental noise.

We have several techniques that would provide a better implementation. The primary tool is the interference mitigation filter.We can design and customise interference mitigation filters that will cease this interference and can be integrated in any device.

CommsMEA: How do you think operators canbest monetize LTE?

Operators around the world are rushing to LTE and they are spending hundreds of millions of dollars on equipment and investing in the frequency. To turn this investment into revenue, the first thing you have to do is set the basic Launchpad. If they have an existing network that is 2G, they have to elevate it to a LTE network. The subscribers are willing to pay more. When the operators upgrade the network to LTE, they will be able to charge more than the 2G system. But, to get this done, the noise performance of the network has to be at least 10 times better than the 2G system or all those investment in radio technology and frequency won’t pay back.

CommsMEA: What does LTE services mean for customers in the region?

From our point of view, LTE now is different, it is not only about the voice, it is about Internet where you can download much faster. When a customer has problems downloading, these are related to the network. The operators have to look at the network completely differently. It is not about adding more sites or services, but about optimising the network and reducing the noise. They have to know how to design their network to improve it and manage it.

CommsMEA: How are regulators promoting LTE?

The operators need more help from the regulatory authorities. Unfortunately, the regulators haven’t given them the frequency to upgrade their networks to LTE. Before, they used to pay a lot of money for the licenses for 2G and 3G, but now it is not about the money. Now, we need these networks because customers are demanding them. Until now, the regulators haven’t given frequency efficiently. The regulators are not open enough, you need to have a free spectrum to work on LTE. The operators are using their existing frequencies.
