There is a new kid in town in the Wi-Fi arena with the introduction and implementation of “Wi-Fi Direct”, the latest standard to come from the Wi-Fi Alliance. This new protocol allows certified devices to communicate with each other via wireless technology without needing the middleman device such as a router. Wi-Fi Direct uses WPA2 encryption technology and will be compatible as a one-to-one networks or a one-to-multiple network.
Before you think that this technology is years away from implementation, the Wi-Fi Alliance has already begun certifying products for this new protocol. Designed to connect devices anytime without being in vicinity of a hotspot, devices will implement push button activation. Certified devices can connect with other certified devices with existing 802.11 a/b/g/n capabilities.
Wi-Fi Direct devices will operate in the 2.4 GHz and 5 GHz frequency band , typically supporting speeds of up to 250 Mbps and have a range of up to 650 feet.
Devices can connect to either through a network or other compatible devices, and when implemented in a network setting. a single device will act as the access point. As a network administrator I instinctively think about security issues, but the Alliance has also thought of those scenarios and these devices will operate in a security domain that is totally separate from the infrastructure network.
Initially I think this technology will be more popular with the consumer market as the business world is much more cautious concerning network access points. Many administrators will be concerned with the fact that if all wireless PC’s are capable of being wireless access points the potential of security breaches increases exponentially.
It will be interesting to see where this technology takes our computing experiences? What are your thoughts?
