 signage, power meters, and health monitoring devices. It is also perfectly suited for integration into surface-mountable modules. CHAPTER 3 DEPLOYMENT CHALLENGES IN EVOLVING 4G Some of the technologies that have been discussed in this chapter are concerned with power consumption, and having a small footprint for the device can be seen in some excerpted product highlights such as: Throughput up to 50Mbps DL/25 Mbps UL 40 nm CMOS technology 4G-EZ ultra-low power technology High-performance LTE RFIC supplied by Fujitsu Semiconductor Dual RF ports The Fujitsu MB86L13A, which the Firefly solution uses, is itself marketed as an IoT ready LTE-optimized transceiver, and though it is primarily targeted for LTE mobile handsets, the vendor does claim support for additional devices. These devices, with the key use being a mobile Internet device, include dual RF ports, mobile phones, cards, and embedded modules. It is to be noted here as elsewhere that LTE as a standard has evolved to better cater to trends like the IoT for better interworking and optimization, much of which is part of LTE-Advanced specifications (Rel 10 and above), which is beyond the focus of this book. Also, it can be expected that there will be plenty of innovation in integration of IoT with LTE networks. The following section gives some pointers to aspects of the LTE RAN, which could be tuned in anticipation of devices that participate in IoT: Data usage and frequency: IoT devices that connect to the Internet directly could work on the following two modes: The devices could be more like sensors that need to send small chunks of data in real time in periodic intervals: Traffic profiles: In such scenarios, the traffic and the bearers in uplink alone could be modeled after VoLTE bearers that also have similar characteristics. Data dimensioning needs to be done for the size of the packets and the rates of the bearers assigned to ensure QoS is satisfied. Latency requirements need to be checked from the point of view of the application, and this may also dete
