CHOOSING THE RIGHT 11N - from Qualcomm
The good news: the 802.11n specification offers a lot of different configurations from 1- to 4-stream options, operation in either or both the 2.4 and 5 GHz bands, and a variety of optional features like spatial multiplexing and 40 MHz mode.
- What applications with what bandwidth requirements will the product support? Simple data functions like email, web browsing and downloading YouTube files or high-definition videos and playing high-resolution video games?
- Where will the product be used most often? Home? Office? On the go?
- Will interference from other devices— household products like microwaves and baby monitors— be an issue?
- How many other Wi-Fi®-enabled devices will operate in the product’s environment and compete for the available wireless spectrum?
- Will the device need to connect at long range (more than 100 feet from the router or other devices in the network) or not?
- What is the desired price range of the product?
- Good for data functions like email, browsing, data file transfers, standard definition video applications like YouTube, audio transfers, low-res gaming
- Good in environments relatively free of interfering devices such as microwave ovens and baby monitors
- Good for functions that require no/low latency such as HD video, real-time, high-resolution video gaming
- Better for environments fraught with interference from other networks and household devices
- Today’s networks and consumer electronics products increasingly employ the best of both worlds with dual-concurrent 2.4 and 5 GHz, offering 27 aggregate unduplicated wireless channels that enable network management, allocating the 2.4 GHz band for data-centric applications and 5 GHz for multimedia
