Dell Streak  (Source: SlashGear)
Streak is a 5-inch MID from Dell running Android 2.0

Dell is doing all it can to add new businesses to its offerings in the form of services for migrating to Windows 7 and new consumer electronic products. This is in the face of slipping from the second place spot in the global computer shippers list with Acer taking its spot.

Dell CEO Michael Dell has been talking quite a bit about the Dell smartphone that is coming early next year and rumored to be hitting AT&T. A smartphone isn't the only Android device that the computer maker has up its sleeves. Today a new MID based on Android from Dell has leaked online. The device is called the Dell Streak, has a 5-inch WVGA 800 x 480 resolution touchscreen, and runs Android 2.0.

Other features of the Streak include Wi-Fi, Bluetooth, and 3D WWAN connectivity. The device is a prototype and sports a 5-megapixel camera with dual-LED flash. A microSD card slot is available for memory expansion and the battery is a 1,300mAh unit. The front of the device has a minimalist design with only three buttons.

A front facing video camera is available for video conferencing. A docking connector is offered along the bottom edge and the label on the prototype reads US, which seemingly means versions for other countries will be offered as well. Other important details like pricing and availability are unknown at this time.

...3D WWAN connectivity...

You mean wireless don't travel in 2D?! OH LAWD.

A wavefront can be viewed as a plane, but that doesn't mean electromagnetic waves move in only two dimensions. After a signal is radiated it expands in all directions unless constricted (parabolic antenna, atmospheric conditions, etc).

Sigh... You confused the electromagnetic "field", which is omnidirectional, with electromagnetic "waves", which are Poynting vectors. The field is made up of the waves shooting in a spherical pattern, which is why I said the waves only travel in two directions.

Technically, I should be calling the "waves" by the term "radiation". EM radiation exhibits wave–particle duality, but the particle behavior was discovered later as it requires examination over shorter distances, i.e. more sensitive equipment. As a result the name "EM waves" came first and stuck, but what's key is the particle behavior.

Those particles are photons. They carry energy and radiate from a source of origin, which is represented by the Poynting vector. The two byproducts of the EM radiation are electric waves and magnetic waves, oscillating around the vector at 90 degree angles to each other.

So, each wave, electric and magnetic, actually operates in two dimensions. The first is the dimension that passes through the vector, from the origin to the photon's destination. The second is the plane of oscillation.

I think you are getting confused with the image of electromagnetic radiation that is used for explanation purposes in standard textbooks. The oscillations you speak of are fluctuations in the field - up/down and left right are just convenient 2D representations ... as another poster has mentioned, the actual waves, unless constrained, spread out in all directions.
