Frequency refarming supports effective spectrum re-use of mobile broadband
In refarming, existing spectrum is re-used to deploy new radio access technologies. Operators improve customer experience and gain extra revenue by offering mobile broadband on existing frequencies. These frequencies are usually employed for GSM, CDMA, 3G or other technologies.
The Nokia Refarming solution increases radio network efficiency in several ways. It improves indoor coverage, enhances customer experience in urban areas and brings mobile broadband to new users in rural areas.
What drives refarming?
Refarming provides better customer experience and lower Total Cost of Ownership (TCO) for operators. The main driver is the demand for more mobile broadband capacity as traffic doubles annually.
Network refarming is supported by a large device ecosystem covering different refarming options.
Why Nokia Networks?
Nokia Networks has years of refarming experience under its belt, with more WCDMA/HSPA 850/900 networks and larger LTE 1800 networks than any other vendor. It also has an in-depth knowledge of refarming services:
- World's first commercial WCDMA 900 network (for Elisa, Finland in Nov 2007)
- World’s first commercial re-farmed Dual Cell HSPA+ 900 network (for Vodafone, New Zealand in 2012)
- Superior technical solution for radio frequency (RF) sharing
- Unique GSM software – Liquid Radio GSM Software Suite – supports refarming with extremely narrow frequency bandwidth with same GSM performance. It frees up 55% of spectrum capacity for refarming WCDMA and LTE
- Flexible selection of bandwidth allocated to WCDMA carrier depending on the operator’s spectrum: from 4.2 MHz down to as narrow a spectrum as 3.8 MHz
- Dual Cell HSPA+ refarming solution to offer 3G mobile broadband at 42 Mbps peak data rate. Combined with configurable carrier bandwidth, it also allows operators to deploy Dual Cell HSPA+ refarming services in 7.6 MHz (2 × 3.8 MHz) of bandwidth. This is substantially less than the 10 MHz conventionally needed for two carrier solutions
- Narrower carrier-to-carrier spacing achieved with reduced LTE uplink bandwidth: this supports GSM-LTE-WCDMA refarming and coexistence cases and allows an operator to deploy more GSM carriers
- Offers planning and implementation services for HSPA and LTE refarming to help operators increase network performance and capacity
