Compression IP is used to put more data into a given fiber or microwave “link” in wireless systems. Using Compression a higher data rate can be transmitted on lower speed links which are generally cheaper. This is a goal across the industry but few have achieved. When compressing data, some signal quality is lost. Based on its patented technology, IDT has proven that it can do compression with very little loss of signal quality.
IDT IQ Compression IP for Wireless Systems offers the industry's highest performance for 3G and 4G Systems
Compression is used to compress data in wireless systems on the link between the Remote Radio Unit (RRU) and the Baseband Card (wired over CPRI or CPRI over wireless front haul). IDT is the first company to offer commercial IP that supports GSM, WCDMA, and LTE signals at full CPRI data rates, keeping high signal quality at compression rates up to 3:1.
Compression IP makes wireless C-RAN architectures more viable by allowing RRUs to be placed remote from Baseband Pools connected with low cost fiber, saving large amounts of money at the system level. IDT Compression dramatically changes the overall cost of system deployment.

Green Network Deployment?
- Allows deployment of C-RAN and other network topologies at low cost and low network level power with twice the compression performance of others in the industry?
- Compression technology applicable to IQ Samples over various protocols (e.g., Wireless Front-haul, CPRI Link) in BTS designs, allowing higher data rates to be transmitted over existing low cost infrastructure. Existing compression solutions cannot meet these performance requirements at low EVM?
- Reduces the number of fiber optic links required between the Baseband processing resources and the RRH, saving both fiber optic transceiver cost and fiber optic cost
- Enables ?reduction in the cost of the "Remote Radio Head" (RRH)
- Reduces the number and link rate of the SerDes required for a given bandwidth thus enabling lower cost FPGA implementations between the Baseband processing block and the Radio Card
- Reduces Operating Expense (OPEX) of using DWDM infrastructure to connect LTE units to centralized baseband units by reducing the number of links required to carry the same bandwidth.
