Indoor positioning is hard. In this white paper, our R&D team takes you on a journey through the process of prototyping a dynamic indoor positioning solution. From simple nearest-RSSI to multilateration algorithms to our full-blown particle-filter-based RTLS Location Engine, our team illustrates how a robust and scalable indoor positioning solution works.Read Now
The CBRS Alliance is looking more and more powerful every day. The group, which advocates for LTE services in the 3.5 GHz Citizens Broadband Radio Service (CBRS) spectrum, now boasts all four major US cellular carriers (AT&T, Verizon, T-Mobile, and Sprint), cable giants Comcast and Charter, as well as Google, Intel, Nokia, and Qualcomm. It’s easy to see why the cellular carriers would be interested inRead Now
By now, you’ve probably read through Mary Meeker’s 2017 Internet Trends report and conﬁrmed that mobile is still eating the world. Mobile internet usage is growing steadily with average US adults spending 3 hours per day on the internet via mobile devices. As demands for data traffic continues to grow, wireless providers have responded by making adjustments to their LTE technology. If you own one of the newer phones equipped with Qualcomm’s X16 LTE modem (e.g. Galaxy S7/S7 Edge, LG V20, Pixel), your phone may soon run on a new technology called LTE-U or LTE Unlicensed. With T-Mobile already launching LTE-U service in select areas and Verizon not far behind, it’s time to under-stand what the hype and the technology is all about.Read Now
There has been much discussion in the Low Power, Wide Area Network (LPWAN) community about the use of other RF frequency bands for data transmission outside of the typical 868 MHz/915 MHz (LoRa Europe/North America) and 2.4 GHz (Ingenu RPMA) ISM bands. This white paper provides a brief discussion of the pros and cons of using the lower 433 MHz band for LPWAN applications and provides implications for certain use cases.Read Now
This document serves as an introduction to LoRa and LoRaWAN for those considering Internet of Things (IoT) deployments. The primer provides a basic overview of the technology as well as its variants such as Link Labs’s Symphony Link. If you are looking for a more general overview of low-power, wide-area networks (LPWAN), please consider reading Leverege’s LPWAN White Paper.Read Now
Internet of Things (IoT) has demonstrated a clear market need for low-power, wide-area networks (LPWAN). For many business use cases, sensors must have battery-efficient connectivity to unlock the true potential of IoT. Unfortunately, industry wide fragmentation and lack of standards have caused massive confusion over different implementations of LPWAN. The purpose of this White Paper is to clarify key concepts of LPWAN, compare and contrast the different technologies, and provide resources for further exploration.Read Now
In June 2016, the 3rd Generation Partnership Project (3GPP ) -- a consortium of telecommunications standards organizations -- finalized the specification for Narrow Band IoT (NB-IoT). NB-IoT completes the trilogy of major cellular IoT network releases (LTE-Cat M and EC-GSM being the other two) while we await the development and deployment of 5G networks. These three standards are muscling their way into an already crowded and fragmented LPWAN market; positioning themselves as strong contenders to SigFox, LoRa, RPMA, and Weightless.Read Now
