The biggest amount of conversations is achieved using G.723.1 with the network bandwidth of 11 Mbps for
802.11b and 54 Mbps for 802.11g standards.
A big advantage is its backward compatibility with
802.11b. This compatibility carries legacy issues that reduce the throughput when compared to 802.11 a by about 21 percent.
Pre-N is compatible with the older 802.11g and
802.11b standards and they will work at standard speeds with older equipment.
802.11g has data rates higher than
802.11b, but similar to 802.11a.
This technology is newer, tends to be more expensive and the devices and equipment are not compatible or interchangeable with the
802.11b standard.
The Workabout Pro boasts simultaneous support of WAN,
802.11b and Bluetooth connectivity, and also boasts that it delivers reliable performance, even in harsh environments, with an IP54 rating and ability to withstand drops from four feet to concrete.
For example, in a single household, the son can watch a streaming video from an 802.11a-enabled media center or personal video recorder (PVR), while the daughter uses an
802.11b PDA to instant message friends, and at the same time Mom or Dad is using an 802.11g embedded mini-PCI card in a laptop to check e-mails over the VPN.
As of today, there are four--with
802.11b having the largest company install-base.
The current standard--labeled
802.11b, to be exact--is relatively slow-acting and easy to intercept by passersby, as compared with the newly emerging standards, such as 802.11a and, farther down the road, 802.1lg.
You can go with
802.11b, which is pretty popular and widely used, or you can go with 802.11g, which is speedier and full-backward compatible with the "b" standard.
