What is 11 G Wireless LAN?

Question

Is 11 G Wireless a technology? What are the types of 11 Gs available? and how do you differentiate between them?

Answer 1

Yes, 11G (802.11g for the name of the standard) is a wireless technology rated at 54MBs and suitable for Lan use.

There's only one type of wireless "G".

However, most newer cards, laptops. and equipment which support "G" also support the more common (albeit slower) "B" cards which run at 11MB/s. There's another one rated at 54MBs that only works at a much shorter range than "B" or "G". It's called "A", and is seldom used, but I included it for completeness sake.

Any of those speeds is way more than a home DSL or cable modem connection could send in either direction and would just matter in PC-PC communication and transfers within the wireles or wired Lan range.

There is a new wireless coming out that will support a faster speed and greater distances. It will be called "N" (for the specification "802.11n") or MIMO for the technology.

The specifications for 802.11 have not been completed.
Vendors are making and selling "PRE-N", "mimo", or "turbo" routers which are similar to what they think the new standard will be.

At the moment, you should plan on only being able to use the newer speed of up to 108MB/s if all of the equipment is from the same manufacturer, and is all PRE-N or whatever. Regular old "G" or "B" will slow it down.

Interoperability between different manufacturers "pre-n" equipment has been tested and is unreliable at best.
It's usually way short of meeting the stated ranges assuming it works at all.

Unless you need the extra range, you should stick with "G" equipment for now.

In a few months "N" will be ratified, and vendors are hoping that an upgrade will allow their "Pre-n" equipment to be truly 802.11n compatible - that should take from 2 weeks to 3 months.
A year from when "n" is standardized, the price will be down to what G is going for now. And you still may not even be using the full speed of G.

On the low end, I've see G wireless routers that will support a decent number of wireless PCs (8-12) and also have a 4-port Ethernet switch for as low as $25.00 (Best Buy - a few months back).

As with most things, your mileage will vary, so plan on about getting around 74% of the rated speed of any of this.

Decide what your objectives and needs are and THEN figure out what equipment to get to meet you needs.

Answer 2

802.11 G is a wireless technology for creating or extending networks. Wireless G comes in 2 speeds 54MB and 108MB. 54 MB is the basic version and the 108 version is obviously twice the speed. It is typically called speed boosted. The other person is right about checking out wickipedia for this. They have a ton of information although it get a bit technical.

Answer 3

802.11g is a Wireless networking technology that is capable of transferring data at 54Mbps. Check out Wikipedia.

Answer 4

The Super-G PCI Wireless Adapter is capable of transferring file at 108Mbps. That’s 2x faster than normal 802.11g. Supports WPA and WEP and is backwards compatible with 802.11b and 802.11g devices.

Answer 5

specific you nonetheless ought to have a router the two a under pressure connection or purchase a instantaneous router which maximum could have 4-ports for under pressure and instantaneous additionally. in basic terms because of the fact it has a instantaneous card geared up in does no longer mean it is going to connect in basic terms everywhere you're. you need to be interior selection of a instantaneous connection. you could surf the WIFI spots yet on the domicile you will % a instantaneous router on your highspeed internet to deliver out a instantaneous sign. in case you % to surf everywhere you circulate you will ought to get a instantaneous 3G card, I relatively have one to handle journeys and it works like a cellular telephone (you need to have a cellular sign) yet i'm getting countless get entry to and its $fifty 9 in line with month,. thank you
