Why choose a wireless intercom system? Well, how would you like to roam through production environments without being tied down by a cable? Doesn't that sound freeing?
There are many factors to consider when choosing a wireless intercom system. David Onslow in Choosing a Wireless Intercom System discusses the differences between intercom systems in the 49MHz, FM band (200KH - 270KHz), 900MHz, 2.4GHz, 5.8GHz, and in the U.S. only, the MURS (150 MHz) band, and highlights the challenges as well as benefits offered by each of those systems.
You also need to identify and consider the complexity and communication needs of your application and your budget. Clear-Com's basic systems, including the HME DX100, DX121 and DX200, are portable, affordable and suitable for simple applications. For higher connectivity, better performance and intuitive user controls, a better option may be advanced systems such as the HME DX210, HME DX300ES, and WBS670/680. Those with the most demanding criteria would select the comprehensive expert systems offering high capacity and scalability. They include the Tempest2400, Tempess900, Pro850, CellCom and FreeSpeak.
