Personal Tele-Presence 1700 MXP

With a price tag of 6L+, this product is meant for individuals or group of

individuals who spend too much on travel. 1700 MXP comes with inbuilt 20 inch

LCD screen with high definition camera mounted on top. Every action of this unit

is controlled with a remote control, making it more flexible.

To make a call, just pick up your remote, enter URI or IP address of the

other end and press Call. You can connect up to four locations at a time. The

remote has built in sensors and comes out of sleep mode instantly as you pick it

up. It supports most major standards for communication like H.323, H.281, RFC

3550, SIP, etc. Security is provided via DES and AES encryption. Downspeeding

and Intelligent packet loss recovery techniques are used as protection against

network interruption while making video calls. Using downspeeding, you can

remain connected even if 97% of bandwidth is lost.

Setting up this solution requires a public IP and power supply. Simply give a

public IP and you're ready to use this unit. To share presentations, you can

connect this unit with a computer via VGA connector. There is a dedicated button

on the remote making it possible to share presentations with a single press.

True HD experience is only possible if both ends are connected with similar

Tele-Presence solutions. Therefore, one has to pay around double the amount for

two-way HD communication and more for multi-point conferencing.

Another important point is interoperability of solutions from different

vendors. We were able to connect to Polycom's Tele-Presence solution without any

difficulty , which shows the versatility of this product. To test bandwidth

requirements, we created an isolated network with 1700 MXP at one end and

Microsoft NetMeeting on other. To emulate Internet, we used Network Knightmare

WAN emulator. Using this device, we were able to set latency and bandwidth in

the isolated network.

We started with 128 Kbps and found connection was almost impossible with a

lot of disturbance. When we moved up to 512 Kbps, video and audio quality became

good with very low latency. We further increased bandwidth to 1024 Kbps and

found video and audio quality to be excellent. One irritating issue was the

slight lag in audio, which faded away when we increased bandwidth to above

2kbps.

Bottomline: If you are ready to invest substantial amount upfront and

generate RoI through travel cuts then this solution is right for you.
