Cellular Networks

With the expansion of applications for smart phones and with 3G and 4G networks being deployed and planned, cellular network capacity and technology are getting a lot of attention with wireless telecommunications carriers. The demand for higher data rates (broadband) and the abundance of more capable smart phones guarantee:

  • Customers will demand more data
  • Cellular networks must have greater capacity and,
  • Wireless carriers are in a position to increase wireless revenues if they can meet the demand for features and capacity.

Vista is well positioned to support wireless carriers with new cellular network infrastructure deployments, including equipment upgrades, tower construction, and wireless backhauls.

What is a Cellular Network?

A cellular network is a radio telecommunications network that provides wireless communications infrastructure to support mobile radio transceivers (cell phones) located throughout a geographical coverage area. This geographical area consists of many smaller coverage areas called cells where the mobile cell phones are supported by a stationary or fixed-location transceiver called a base station. Base stations provide wireless communications coverage for cells that combine to make up a much larger coverage area consisting of the cellular network. This cellular network design allows for:

  • Frequency reuse that results in increased capacity and increased coverage
  • Reduced transmit power thereby simplifying cellular phone radios and simplifying battery requirements.

Cellular Network Technology Evolution

In recent years wireless communications carriers have been deploying faster cellular networks to keep up with customer demand for data and capability, with the more advanced technologies including LTE (Long Term Evolution) and Mobile WiMAX. Although faster than 3G systems they don’t meet the requirements set out by the International Telecommunications Union Radio Communications Sector (ITU-R) for 4th Generation (4G) technology. The requirements are set out in the International Mobile Telecommunications – Advanced (IMT-Advanced) specification with the requirements including all Internet Protocol (IP) access with data speeds over 1 Gigabits per second for low subscriber mobility, and data speeds over 100 Megabits per second for high subscriber mobility. Toward meeting these objectives there are two new systems under development that are evolutions of the LTE and WiMAX systems, and they are LTE-Advanced and Mobile WiMAX Release 2, both of which are backward compatible.

From the perspective of the ITU-R there currently are no truly 4G networks deployed, however, service providers have branded the LTE and Mobile WiMAX systems as “4G” since they represent networks based on new technology that is not backward compatible. With this in mind the ITU-R accepted the “4G” branding provided that the deployed systems represented forerunners to the IMT-Advanced versions of the systems and provided significant advancement in performance and capability compared to 3G technologies.
