TD-LTE (Time Division-LTE) can play a key role in helping operators to address explosive demand for mobile broadband even when there are limited resources. Operators starting out on TD-LTE today require a mobile broadband network that can be initiated with the minimum possible CAPEX, site cost and OPEX. Going forward, the TD-LTE network should also be scalable – up to a very high capacity – according to the operator’s subscriber penetration. To address this need for a flexible and cost-efficient approach, our engineers have come up with an ingenious offering – our new TD-LTE 8 pipes remote radio head that provides the best in terms of quality, reliability and availability to the operator community.
The remote radio head is the radio component of a base station that resides with the antenna. Part of our new Liquid Net architecture , the 8 pipes product promises significantly higher coverage and capacity at up to a quarter of the cost of conventional remote radio heads when rolling out TD-LTE networks. The new 8 pipes remote radio head enables an operator to deploy a base station as a 2×2 single-sector site and add up to four sectors to meet growing demand, simply using the same 8 pipes radio frequency (RF) module. The site can be further scaled up to 4×4 or 8×8 configuration.
Uniquely supporting four sectors in a single radio head, the new product eliminates the cost and delay of having to add conventional single sector remote radio heads to scale up capacity.
With the 8 pipes radio head, operators need fewer high capacity sites and can enjoy unprecedented flexibility to scale their networks at lower costs, in line with capacity demand.
The new remote radio head supports 40 MHz of channel bandwidth, scales up to 96 watts of transmit power and allows advanced beamforming to deliver exceptionally high downlink capacity. In addition, the baseband module features integrated backhaul to cut the costs of separate transport, to improve latency and support security features such as IPsec in the LTE base station itself.
And what I found even more exciting, the new 8 pipes radio head also has a zero footprint, needs no air conditioning and can be pole-mounted or placed near the tower base for a compact and cost-effective site. The product also features software-defined radio technology, enabling another carrier to be added via a simple software upgrade to LTE-Advanced.
The 8 pipes radio head enables operators to deploy TD-LTE networks with the lowest costs, safe in the knowledge that their investment is protected by a future-proof installation.
