Wi-Fi trends in '05: Mimo, Broadrange
(old news - 06:09PM Monday Dec 27 2004)
tags: wireless · hardware
E-Week explores how the Mimo antenna configuration and Broadcom's Broadrange Technology could usher in a degree of "range warfare" in 2005. MIMO (multiple input/multiple output) is the antenna array at the heart of Belkin's "Pre-N" gear, which has been receiving positive reviews from our forum regulars. Broadcom's "BroadRange" chips are based on 802.11g, and use proprietary technology to extend signal range by 50%, promises the company.

Just another step...

...in the CB-ing of WiFi.

Before long you'll need a 1 KW linear just to make it to the garage.

Unlicensed stuff like this always ends up in a "range war". Just look at how many times cordless phones have been reinvented.

Re: Just another step...

Exactly, and each generation of cordless models sucking more than the last.

Now, I don't have much experience with the 5.8ghz phones, but I always remember 900mhz phones being superior to 2.4ghz phones. You can't change the fundamentals of radio science - as you increase frequency, the wavelength decreases - it just so happens that for buildings with lots of walls and obstructions, the longer wavelength of 900mhz did the trick. While it doesn't have the THEORETICAL range of newer models, the signal is more robust.

5.8ghz rocks for cordless phones. And you don't get any interferance with your 2.4ghz Wi-Fi network. I have two at home and I got them because the 2.4ghz phones sucked.

Giving customers the ability to have such range is dangerous.

Channel 6 is already overridden with people, soon everybody will come to a complete halt, as their networks battle with each other for a slot to transmit in.

Re: Just another step...

They need to add a feature that automatically sets the channel to the best one for use in your environment. But instead most opt'd to default to channel 6 and alot of users don't know better to switch it.

Heck most don't even encrypt or change their default password. I have three neighbors in my apartments that didn't switch it or secure their AP, all running with default password.

I agree. My Netstumbler database is full of entries similar to the ones you've described. At least 55% are on channel 6.

Such a feature wouldn't only be nice, it'd be necessary in an environment like the one above.

This feature is already available in Belkin Pre-N router.

I'm weary of all "Pre-N" gear, despite how convenient this feature may be.

Netgear is making one of those auto-detect best channel Access Points right now(!).

All products defaulting to channel 6 is a good thing. That way people who know what they are doing can use another channel and not have to worry about all the traffic that is caused by idiots.

So if a device has the ability to operate on channels other than 6, that makes the user an idiot if they choose so?

Well. If your in an apartment with 5 different people on channel 6. Then yes. Thats makes them an idiot. Let them have problems with there stuff, while the people that know how to change a channel and know what it means have clean clear reception.

Re: Just another step...

I live in an apartment complex, and I'm lucky to get the wireless devices in my home to go through the sheetrock walls. Most wireless products do not work as advertised. I do have to admit that the design of the building is probably what is causing the wireless problems I'm having.

i think what they need is of course something on the AP where you can select the channel on box itself and not have to enter any config pages(like the channel button on a cordless phone), or maybe even design the equipment so that when it is turned on the first time it does a scan of the area and defaults to the channel with the lowest number of other transmitters.

Broadcom "BroadRange"

I do not know very much about the organization that certifies 802.11g hardware, but wouldn't Broadcom's proprietary implementation of the standard be contrary to the goals of the group of manufacturers that finalized it? Would they support their joint research being used in a proprietary product being offered by only one of the group?

I could be wrong, however, if Broadcom intends to submit its advancements to the other chip manufacturers as part of the group's process.

Can someone enlighten me on the group that certified the 802.11g standard and possibly what Broadcom's intentions are?
