Why 802.11n Should be on your Shopping List in 2010
While our industry has not announced yet any 802.11n products in the form of handheld computers here are the compelling reasons why this upgrade makes sense.
1) Faster. 802.11n will transmit at speeds up to 160M bps and offers better methods of encoding, support for QOS (quality of service) and support for MIMO (multiple input and multiple output) which improves reception for wireless devices equipped with multiple antennae.
2) Support for 802.11a, b, g. Now you can have ONE network supporting both 5 GHz and 2.45 GHz. This standard also supports QOS tagging meaning packets requiring priority such as voice or audio will work a lot better under this new standard. Think of high definition TV signals now being sent over the WiFi reliably and creating lots of opportunities for in store promotions and other applications requiring compelling picture quality.
3) Capacity. It’s all about bandwidth. Now you move voice, data, and video onto the same network without worrying so much about robbing Peter to pay Paul when it comes to adding more applications and users onto the wireless network.
4) Coverage. Superior signal propagation means 802.11n exceeds the coverage of 802.11g; so don’t do a simple swap out. This means an RF Site Survey is needed but also fewer access points means less cost in the long run and easier maintenance. Also the additional coverage allows you to consider making wireless a whole range applications from door controls, temperature sensor controls, to security systems.
802.11n superior features will also spawn faster adoption of WiFi into these technologies: bar coding and data collection (my stuff), RFID, VOIP, data video, and cell phone features that ONLY work with WiFi. So if you’re looking to better track assets, provide better service to your customers or just reduce costs of providing new services then 802.11n deserves serious consideration.
Seasons Greetings, Happy Shopping in 2010, and Scanners On.
See you in the New Year!
