Israeli firm takes silicon route to backhaul problem

Mobile operators facing demand for more capacity and access part – reflecting back onto the backhaul, and this demand keeps exploding. But an Israeli company called Siklu claims to have an answer to the problem.

There are alternatives to providing backhaul, using either wireless or wireline, but wireline takes lots of capacity while fibre costs a lot.

Operators are looking to another way to provide for the demand. Siklu thinks this is 81-86 GHz frequency band, the e-band. there’s quite a big chunk of this allocated already. Siklu thinks it has the potential to provide high capacities, in urban deployments.

It claims that it is able to provide high capacity, high performance wireless links, with  a cost structure that is far cheaper than those that exist now.

Siklu thinks the mobile backhaul market is big enough  to justify designing backhaul  from scratch. It says that it’s designed the whole supply chain, and controls it all. It has designed its own antennae and to lower the price it’s done some integration and uses silicon design. The market is big enough, it thinks, to justify going to silicon.

It has put the whole radio into a single RF IC and also has its own baseband modem chip. which works together with the RF. A third party network processor does all the switching,

Siklu says it’s a high performance, low cost network processor, currently offering layer 2 switching – which can be upgraded later on , if you need MPLS or other capabilities.

The company released its product in the second half of 2010 and beta trials have ended – in Q4 it began shipping products.

Siklu executives told TechEye: “We’re all data consumers, – it is not only here to stay but it is here to  continue and grow. and backhaul is one of the key challenges. It is  n attractive offering to help mobile operators cope with the [challenges]  – and that’s before LTE and 4G.”
