RAN testing suite configured to support simulation of devices on the – accelerating the speed of IoT deployments

Prisma Telecom Testing (Milan, Italy), provider of test and measurement technology for the wireless industry, has added 3GPP IoT devices emulation to its Radio Access Network (RAN) testing suite, enabling both network manufacturers and service providers to accelerate the deployment time of IoT devices.

Prisma RAN test systems are already being used by the major network manufacturers to validate 2G, 3G and LTE use cases. By extending this technology to include IoT emulation, equipment vendors, operators and IoT network providers will be able to verify support for all types of connected devices, vehicles and machines well before their actual deployment. This will encompass the complete range of industrial, smart city and smart home technology, in addition to enterprise applications expected to use the latest 3GPP protocols.

IoT and M2M network design is fundamentally different to traditional network structure, as although the majority of IoT devices will require relatively low power and throughput, the sheer number of connected devices will place an unprecedented set of demands on cellular infrastructure. To ensure the success of IoT applications, all elements must be tested against specific standards being introduced by the 3GPP in its Release 12 and 13, including the LTE-M narrowband frequency configured specifically for M2M communication.

Prisma Telecom Testing’s RAN test platform supports the simulation of these Cat-0 and LTE-M devices, enabling the validation of network equipment to support IoT implementations well ahead of chipsets production and commercial device release.

LTE-M Rel. 12 Cat 0

Release 12 introduces a new LTE device category (Cat-0) with the target of lowering the complexity and cost of devices with some simplifications:

·         Half duplex FDD operation, to avoid for the duplexer filter

·         Reduced receive bandwidth to 1.4 MHz within the LTE system bandwidth up to 20 MHz

·         Single receive chain – no MIMO

·         Lower data rate

LTE-M Rel. 13 Cat M

Release 13 introduces a new simplified device
