Klj 7a is liquid cooled radar that will be used in jf 17 then why it is said air cooled.

LKF601E is famously claimed to be air-cooled AESA radar... KLJ-7A is said to have the same performance specifications as that one, which are already lower than undertrial Uttam's, inspite of DRDO's typical conservative claims.

Also being so heavy, while sitting on the nose it will negatively affect the already mediocre maneuverability of the plane.

but it says something else

So jf 17 will use air cooled radar.

No, but it will use will be of same performance as air-cooled one which, even by Chinese boastings, is inferior to Uttam's (which will take a few more years to mature. A2G seems to be unsatisfactory compared to A2A mode.)

If it really detects 5m² RCS at 170km, then 0.5m² Tejas Mark1 can have Jf-17 within its Astra/Derby BVR's No Escape Zone (NEZ) even before it gets located itself... Tejas will track Jf-17 from atleast 100-120km away.

it's inter squad communication networks every small group's like composition of 3 to 10 have this set up where one with stat com act as mother node it will be mesh network in to others thus using Bluetooth as communication protocol its will be suitable for small company size networked soldiers aporch, but other things they showcased pretty much common things the bit vault secure phone also nothing new

Buying SATCOM for every squad in the Indian Army must be expensive. The communications engineer must dismount, pull out a huge pack and assemble the antenna assembly, track the satellite location and establish a connection. He can't move while transmitting and then must tear it all down and repack for the next location. To top it off you must have enough bandwith on your telcom satellites to maintain the traffic of the entire Indian Army. I don't think the US even has enough bandwidth to do that.

If it really detects 5m² RCS at 170, Tejas Mark1 can have date 17 within No Escape Zone of its BVR even before it gets located.

Weight of klj 7a is 145kg it is not suitable for light aircraft.

 

[Atcjurvin]

How can you say it is inferior?

 

[Bleh]

How can you say it is inferior?

From whatever is publicly available...

If it really detects 5m² RCS at 170km, then Tejas Mark1(0.5m²) can have Jf-17 Block3 within both its Astra & Derby BVR's No Escape Zone even before getting located itself... Uttam or ELTA radar in Tejas will be able to track Jf-17(1.5-2m²) from atleast 100-120km away.

not really actually its a just a tranreceiver just like handhelds, there was a prototype I saw in Milan international exhibition in Italy can't recollect its name,the version u said used for mostly Base or camp operation not for mobile operations

Class 1 works upto 100mtrs.

With use of repeaters, the distance could be extended further.

It's mesh network based communication system.

A private company called Sterlite technology has developed OFC based smart fence. The system an integrated approach to smart border management, which includes OFC based vibrational sensors, cameras, searchlight, automatic alarm systems, on the front end and AI based data processing and automated control systems on the back end.

A private company called VNL has developed a Mobile Integrated Network Terminal (MINT), which has been tested at various locations by the army for the last 1.5 years. It is to established broadband connectivity to the soldiers in very remote areas. The smallest versions is a manpack, which can be carried by a soldier on his back,with 4 hours battery life. Connectivity options include SATCOM, microwave and OFC. Supports data speed of upto 100 Mbps. Also can be made to run on solar power.

Wonder why MOD never consider these potential gem of an idea and equipment.
Just what are they waiting for, I don't think their are any more competitor of this, or are they waiting for any foren maal.

Those tactical radios you are speaking of don't directly talk to the satellite, they talk to a much bigger Ka SATCOM node mounted on a communications vehicle or base camp station. Their range is only LOS to the node. That is why France is using Aerostat communication nodes to extend the range of that LOS.

this moron again made one video about arjun seems like he is obsessed with us and taking out his frustration every time he wants.

Don't take what this Russian guy says too seriously. He makes video saying Leclerc is obsolete when he basis it off of 90s configuration disregarding the MLU. He is a total clown.

It doesn't matter what the node is, if the soldier can't go more than 100 meters away from it then he is tethered to it. Does every squad have SATCOM in their unit?

Problem with us is that we associate each and every product out there with Army, Navy or Airforce and think from that perspective.

An IA platoon out on patrol will primarily depend on their dedicated SATCOM for communication with base station. LF radio set comes second. But devices like these are complimented by third line of communication devices like these.

Back in early 2000 there was a project being carried out for HM. It was for satellite based communication for voice and data. Although the posts were already connected with LF based radio, but the project been implemented for secured Voice and Data transfer. The main benefit of the project was seen in data transfer. The officials when on patrolling would capture images across the IB on their Point and Shoot cam and the same images would then be transferred to HQ for further evaluation. But before implementing the project, it would have sometime taken months before HQ receives those images. After implementing the project, once the team reach their base location they could immediately transfer the images. But that too would take atleast a month time as this is generally what it takes to complete a patrol.

But now imagine a device like this in hands of those patrolling parties. They could immediately relay those images to HQ from field. Army or defence forces does have the leisure that they are provided with dedicated SATCOMM during patrol, but same is not true to other agencies. For them system like these are a boon. Not only in our borders, we have need of such systems in our interior parts like Dantewada which is not covered by mobile network. Operators operating in those regions don't carry a Satellite phone, but do have a mobile phone. So don't look at this from a single perspective.
