The Nokia 810 Internet Tablet will have WiMAX support in a new version expected to come out this summer.

WiMAX is a wireless broadband standard that is being rolled out by Sprint under the Xohm brand. It is capable of 2-4 Mbps download and 1 to 3 Mbps upload speeds. This compares to 3G EV-DO speeds tested recently as having an average download speed of 1.1 Mbps and an average upload speed of 511 Kbps.

The addition of high-speed WiMAX to an Internet Tablet that already has a built-in camera might make a compelling mobile video conferencing device.

G-Talk used to have video chat function for the Nokia N 800 series but it has since been disabled. Perhaps Skype or Gizmo will give us video capability.

It’s just a rumor but Kevin Rose of Digg puts forth that the second generation iPhone will allow video chat.

Rose claims in this video clip that the new 3G iPhone will have two cameras, including one in the front specifically for video conferencing.

I wonder how much latency and jitter will be on the AT&T 3G network.

Streaming a live two-way video conversation over a cellular telephone network will be challenging. The experience will have to be great in order to meet the expectations of iPhone users.

Maybe it will be primarily for video chatting over the iPhone’s WiFi connection. I could see that as more feasible.

Handheld devices that let you video chat over WiFi or 3G networks are the ultimate in personal videoconferencing. So far we haven’t seen much in the way of these mobile videophones here in the US.

British Telecom and Sony have released a free service for the PSP gaming device that turns it into a wireless personal communicator with IM, Voice and Video Chat.

You need to buy an add-on Go!Cam which attaches to a slot in the top of the PSP and download the free Go!Messenger software.

The Sony PSP Go!Cam has a 1.3-megapixel sensor, a built-in microphone and it rotates 180° so that you can point at your face or shoot straight ahead to show your surroundings.

The Go!Cam and Go!Messenger lets you make free video calls to other similarly equipped PSPs and also to PCs with the free ”BT Softphone 2” software installed.

The Video below is a demo of a live video call from the Sony PSP Go!Messenger.
