Critical Infrastructure Requires Precise & Reliable Timing
When it comes to investing, precise timing is everything. The value of microseconds in financial transactions and High Frequency Trading (HFT) is rapidly reshaping the financial world. iPosi’s iP-GPS signal integration process provides secure jam-resistant, sub-microsecond time synchronization with globally standardized, traceable GPS/GNSS precision and accuracy.
Most public power systems rely on combining generators from across a region or entire country. To achieve highest efficiency, bring up peak generation capacity quickly and maintain highest quality service, utilities manage their and neighboring providers’ generators to within a few microseconds time that translates to phase.
iPosi iP-GPS provides in and outdoor timing solutions to combat potential jamming and provide GNSS signal diversity to the power industry.
When it comes to interconnected systems that monitor, control, produce, track, or transact, GPS timing is vital. Whether it’s aviation, homeland security, emergency services, communications networks, or other government functionality, critical infrastructure relies on essential GPS/GNSS time to synchronize their networks and monitor sites. Government agencies are increasingly aware of higher dependency on global positioning as the primary means of timing. Sources of robust anti-jam receiver solutions to combat outage have been an issue, whether the jammer source is determined to be intentionally interfering or not. Further, regulatory agencies are sensitive to the cost of locating and enforcing jammers with dispatch that its constituents expect.
iPosi iP-GPS provides an assisted solution to secure GPS/GNSS timing points or networks to harden infrastructure against sustained or transient jamming threats, real or potential.
Internet networks are increasingly being augmented to synchronize traffic or disseminate time across their networks through asynchronous IP based routers and switches. Various time or frequency dissemination protocols are used to develop synchronized services from the core out to remote points in the network.
iPosi iP-GPS provides an alternative solution that complements and reinforces packet synchronous protocols by delivering increased time transfer precision with less expense than imposing substantial changes to existing access and wireless backhaul network infrastructure.
Small Cell/Femto Cell
Small cell devices are rising with rising demand for wireless data, especially as users demand richer content that increases data rates significantly. 4G LTE represents the next wave of licensed femtocell technology and 802.11ac offers gigabit class unlicensed WiFi for carrier off-load. Both services require location for various reasons: public safety, spectrum management, shared spectrum access, radio resource optimization are examples. LTE requires microsecond grade time synchronization and upcoming LTE services demand 100 nanoseconds or less time precision.
iPosi iP-GPS provides a low cost embedded solution to both locate and synchronize Small and Femto- cellular products to work indoors using existing network and access point resources.
VoIP represents the fastest growing consumer and enterprise category of station based telephony service. However, VoIP technology is packet based thus designed not to be exclusively tied to a traditional telephony access line, literally one implemented using a copper wire-pair that is physically dedicated to each subscriber and terminated inside every local exchange central office. To ensure equivalent reliable E911 service, VoIP often requires manually intensive, potentially expensive or difficult to manage device location mapping ensuring customers of instant, reliable E911 service when there are “moves/adds/changes.” A segment of VoIP devices is designed to move at will which compounds E911 safety response further.
iPosi embedded iP-GPS provides a solution for VoIP E911 using its assisted GPS/GNSS link to serve VoIP customers fixed or “nomadic” devices and works indoors, including enterprise buildings and consumer homes that is standards compatible.
