1. A method of providing positioning system information, comprising:
- generating, at a transmitter, a range block including a ranging signal;
sending, from the transmitter, the range block, wherein the range block is sent in a predefined slot of a plurality of predefined slots comprising a first transmit frame;
generating, at the transmitter, a hybrid block including a positioning signal including positioning data;
sending, from the transmitter, the hybrid block, wherein the hybrid block is sent in the predefined slot in a second transmit frame disjoint from the first transmit frame;
generating, at a second transmitter, a range block including a ranging signal; and
sending, from the second transmitter, the range block, wherein the range block is sent from the second transmitter in a second predefined slot of the plurality of predefined slots.

Abstract
Devices, systems, and methods for sending positional information from transmitters/beacons are disclosed. In one implementation a transmitter generates a range block including a ranging signal and a hybrid block including positioning data, and sends the range block and hybrid block in predefined slots in a transmit frame. A receiver in a user device receives signals from a plurality of transmitters and generates position/location information using trilateration and measured altitude information in comparison with transmitter altitude information.
