iDirect and 3G Backhauling

Richard DeasingtonBy Richard Deasington

iDirect is well known as a provider of 2G / GSM cellular backhaul solutions with over 40 networks in operation around the world – including the largest VSAT cell backhaul network that is deployed in China with around 1,200 sites.  However, most new networks deployed now are 3G HSPA networks that offer high-speed data at up to 11 MB downlink speed as well as conventional voice and SMS services – can iDirect satellite infrastructure support this traffic? 

The short answer is ‘yes’!  iDirect worked over the past year with several leading vendors of 3G infrastructure to ensure that it operates efficiently over our D-TDMA networks and also so that we have the best network settings already prepared for implementing these networks.  We have just completed a round of testing with the very latest 3G technology and you can expect to see a public announcement on this in the next month or so.  As a taster we can say that achieving 3G connectivity from native IP- connected 3G Node Bs (base stations) has proved quite straightforward and multi-megabit throughputs can be delivered.  Our combined SCPC Return and TDMA networks can now easily handle this level of traffic using the most appropriate technology depending on the throughput required and the traffic characteristics.

Panasonic looks to test new Ka-band antenna by 2Q 2012

From, By Mary Kirby

Panasonic Avionics is pressing forward with the development of a new Ka-band antenna and hybrid Ku/Ka antenna to support ultra-high-speed airborne Internet when Ka-band satellite-based connectivity becomes available, and says it is looking to begin testing in the second quarter of next year.

“Today, Panasonic is actively pursuing a Ka antenna R&D development, as well as a hybrid Ku/Ka antenna development. Panasonic is working with a key technology partner to develop our antenna in anticipation of Ka becoming available for the aviation market in the 2012/2013 time frame,” says a Panasonic spokesman.


Tampa Microwave X Band ManPack Satellite Terminal Offers Battery Saving Feature


TAMPA, Fla. – (BUSINESS WIRE) – Tampa Microwave(TM), a veteran owned small business specializing in satellite communication systems, microwave modules, satellite link simulators and carrier monitoring equipment announced the completion of verification testing of a significant battery life improvement feature that manages the power required for its Manpack family of X, Ku and Ka band ultra portable satellite terminals.

In cooperation with iDirect Government Systems, Tampa Microwave has designed its terminals to implement a Transmitter Keyline feature. A Tampa Microwave terminal using iDirect’s V2.3 modem software disables its transmitter until commanded by the iDirect e850MP modem to send a data packet. When packet transmission is complete, the Keyline returns the amplifier to standby mode to await the next transmission. Using the Keyline extends the terminal’s battery life by a factor of at least 2x up to a maximum of 3x depending on the transmitter duty cycle.
