Tailoring a GeoLENs solution to your environment

The flexibility inherent in the GeoLENs solution enables you to customize a location-enabling system based on your specific broadcast environment: IP, SUPL, GSM, LTE, UMTS/WCDMA, individually or in any combination. Scalable and future-proof, GeoLENs grows with your network, adapting as new locating technologies and broadband protocols.

Based on your unique broadcast environment and location needs, Andrew can design, install, and support a customized solution that maximizes your revenue and service potential while minimizing your CAPEX and OPEX levels.

Recommended GeoLENs Solution for Indoor Environments

Nearly 60% of all wireless calls originate or terminate from indoor locations such as office buildings, shopping malls, airports, hospitals, and sports arenas. For wireless operators and facility owners looking to take advantage of the demand for location-based services, that’s an opportunity and a challenge. Now CommScope provides the solution: GeoLENs Indoor.

What is it?

• GeoLENs Indoor enhances caller location reliability and accuracy when other location technologies are compromised, such as when wireless callers are inside of structures or in “urban canyons”.
• GeoLENs Indoor can locate a target mobile to within a few meters. In multi-story buildings, it can locate callers to specific floors.
• GeoLENs Indoor is an overlay location solution that integrates with existing Distributed Antenna Systems (DAS) or wireless repeater systems. It can also be deployed with its own dedicated antennas.
• GeoLENs Indoor works with any handset without modification.
• GeoLENs Indoor produces high-accuracy caller locations when GPS and other wireless location methods can’t.

GeoLENs Indoor consists of:

Indoor Location Server (ILS)

• Central control unit for systems of up to 3,000 remote Proximity Detection Units (PDU).
• High availability redundant architecture using COTS central servers and routers.
• GUI for operations and administration (OAM) and to monitor and control system performance.

Proximity Detection Units (PDUs)

• Radio signal sensors distributed across the area of interest to detect mobile transmissions.
• Support 2G and 3G networks and multiple bands (850/900, 1800/1900 and 2100 MHz).
• Two versions available:
  • Version one can locate a mobile in up to 12 location zones and is frequency agile across all cellular and PCS bands.
  • Version two can locate a mobile in up to 18 location zones [6 zones per frequency band (900/1800/2100 MHz)].
• PDUs connect to the ILS via TDM or Ethernet.

How does it work?

1. ILS (the system control unit) is requested to find a target mobile.
   • ILS can receive location requests from BSCs (over Lb), RNCs (over Iupc), or SMLCs (over Lbis).
   • Target mobile must be in an active session (i.e. non-idle) with the wireless network in order to be located.
2. ILS tasks the appropriate PDUs to detect and measure the target mobile’s signal.
   • ILS uses information received in Step 1 to determine which PDUs to task.
3. PDUs detect and measure the target mobile’s signal and send the measurements to the ILS.
   • Existing RAN backhaul is typically used to connect ILS with its PDUs.
4. ILS applies proprietary proximity detection algorithms to determine the zone in which the target mobile is located.
   • A zone is the coverage area of the antenna that feeds into a PDU port.
   • ILS provides pre-provisioned location information for the zone to the entity that initiated the location request over Lb or Iupc.
