increases through load balancing and interference management. Andrew also provides easily
integrated element managers for the remote access and control of repeaters and TMAs. These
tools are aimed at enhancing the operators’ ability to implement optimization plans quickly and
reduce operating expenses significantly.
� Geolocation – Andrew is a market leader in wireless location services, supporting wireless
operators in their efforts to meet E911 regulatory requirements with systems that enable both
E911 and commercial location-based services (LBS). Andrew’s GeoLENs Mobile Location
Center (MLC) is a commercially available, industry-leading system used for the location of mobile
phones connected to 2G-GERAN and 3G-UTRAN networks. The GeoLENs MLC can coordinate
systems that use Location Measurement Units (LMU) to monitor air interface signals for both
macro coverage uplink measurement methods and using proximity-based location determination
in conjunction with indoor coverage solutions. The MLC supports a broad range of options for
location determination methods that can be licensed as required by both volume and coverage:
o Cell ID (CID)
o Enhanced Cell ID (E-CID) using Timing Advance (TA)
o Network Measurement Report (NMR) in the GERAN
o Round-Trip Timing (RTT) in the UTRAN
o RF Profiling
o GPS (Autonomous, Network-Assisted and Device-Assisted)
o Hybrid A-GPS combining satellite and network based measurements for optimal yield
and accuracy
The GeoLENs platform enables a wide variety of emergency, commercial and security related services.
Andrew is evolving the GeoLENs MLC to seamlessly support location services in LTE networks in
accordance with the recommendations of both the 3GPP and Open Mobile Alliance (OMA) specifications
groups. 3G operators migrating to LTE will be able to add the LTE node functionality as required to
existing GeoLENS MLC platforms already supporting their 2G and 3G networks. CDMA operators
migrating to 3GPP/LTE will be able to deploy a proven platform into their new network environment.
Andrew is at the forefront of standardization efforts both in 3GPP as well as in the OMA forums. Andrew
is actively involved in the Rel-10 standardization efforts to specify the wireless location services
architecture, technologies, and protocols and is an active contributor as OMA finalizes SUPL 2.0
definitions and initiates work on SUPL 3.0.
Andrew’s products will support current 3GPP releases and product roadmaps will continue to be
developed to ensure future compliance to 3GPP specifications.
