There are 4 options to consider in developing a new device: An integrated device that supports the core functionality needed for your application. Advantages - no certification costs, proven performance, shortest time to market Disdavantages - higher per unit cost & limited flexibility in the functionality Examples - Typcial Deployment Range - 1 to 1000 Vendors - depends on application An end product is a standalone wireless product that can be integrated with other hardware to form an integrated device. Advantages - no certification costs, proven performance, short time to market Disdavantages - per unit cost Typcial Deployment Range - 1k to 10K Vendor - MultiTech's Socket Modem www.multitech.com An integration with a module Advantages - lower per unit cost, flexibility in form factor, reduced operator certification (assuming the module is pre-certified by the operator) Disadvantages - certification costs (PTCRB - $20K-40K), operator certification may be required (typically no cost) Typical Deplotyment Volume - >10K Vendors - Cinterion, Telit, Sierra Wireless, Ericsson, Motorola, Enfora, Simcom An integration with a chipset Advantages - lowest per unit cost & flexibility in form factor Disadvantages - certification costs (PTCRB - $60-80k, Operator - up to $500k), long time to market 12-24 months & high level of wireless expertise is required for development Typical Deployment Volume - 1 million Vendors - Infineon, Qualcomm, Marvel, MedioTek, Texas Instruments, ST Ericsson, Freescale As you can see, it really depends on where you are with your business model, but there are options to meet every need. Also, I highly recommend contacting your operator to find out their requirements.
