LTE-FES (Band Shifters)

Enabling Private LTE Networks over Private Spectrum

Doodle Labs has taken its leadership in frequency shifting Prism technology to develop a family of band shifting {Patent Pending} LTE-FES products to enable the use of state-of-the-art, high performance 2×2 MIMO LTE-A equipment to operate in proprietary bands. The LTE-FES simply acts as compact, in-line module between the LTE modem and the Antenna. The main benefit of this solution is that all the existing tools for network and traffic management continue to work without any changes. Only the RF part of the equipment works at a different frequency.

The Rise of Private LTE Networks

Many government and commercial organizations around the world have access to a swath of un-harmonized spectrum (e.g. Military, Utilities and Railways). However, due to lack of readily available LTE equipment, these spectrum assets remain under utilized. IoT is leading waves of network-led transformations. The wireless network is gaining an instrumental role in supporting the mission critical functions over a large area. The need for high-performance wireless networks that support dynamic, distributed and highly mobile environments has become obvious.

While a range of wireless technologies are available, LTE has been rapidly seizing mind share as a platform for the future. It provides the low latency and high throughput required for specialist telemetry and control applications, while also providing the extended reach that allows sensor and control systems – both static and mobile – to be easily connected over vast areas. Perhaps the most significant attribute is LTE’s traffic management and the ability to extend QoS over-the-air to devices in the field. This allows multiple traffic types with different criticalities to be brought together onto a single infrastructure without sacrificing the integrity or dependability of the overarching applications.

With lower cost Small Cell architecture, the barriers to entry for LTE networks are dropping to the point that many organisations are putting themselves on the path to owning and operating their own private LTE infrastructure, for their internal use, and in complete independence to existing Service Provider mobile networks. However, getting access to the spectrum still remains a challenge.

Available LTE-FES Models

We usually configure the LTE-FES to meet the specific project requirements and sell them in wholesale quantities. Below table lists few of the completed projects. Please take a look at the General Specifications to better understand the design block capabilities.  Please contact us to discuss your project requirements. We will be happy to work with you.
