With the mobile data market set to double from 2015 to 2017 and High Throughput Satellites (HTS) creating a cost-effective alternative for delivering broadband while reducing OPEX, the cellular backhaul market is a promising one – but does not come without challenges.
A Changing Landscape
3G and 4G technologies, newer smartphones and the explosion of social networking are fueling the growth of satellite backhaul even in the traditionally difficult rural and remote areas. The enhanced user experience provided by 4G over satellite is no stranger to this shift and consequently the landscape for satellite mobile backhaul is changing significantly.
While voice required dedicated satellite capacity to guarantee Quality of Service (QoS), data needs solutions which provide statistical multiplexing and dynamic bandwidth allocation. However, voice traffic must still be preserved. The ability to guarantee its availability – even under adverse conditions – is crucial.
Adding to these challenges is the fast-paced nature of the mobile world where huge investments are at stake. Competition is fierce, with more than four mobile operators often fighting for the same markets and putting a toll on profitability. Infrastructure manufacturers have to be creative, propose financing and revenue sharing options to win business and allow mobile operators to upgrade their infrastructure. This has a direct impact on satellite backhaul – it has to be extremely efficient to save bandwidth (spectral efficiency and dynamic bandwidth features), preserve QoS and provide Quality of Experience (QoE) in order to alleviate the inherent satellite delay.
The Impact of HTS
HTS is a game changer for mobile backhaul: it provides high throughputs suitable to the greedy mobile applications but at a much lower cost. However, success in the satellite backhaul market cannot be achieved with HTS alone; it is only by combining it with other technologies such as 4G, spectral efficiency and dynamic bandwidth allocation that operators will experience its full benefits.
Overcoming Obstacles with Technology
QoS, QoE and affordability are key differentiators in many markets. The satellite backhaul response to these requirements is to provide solutions which spare bandwidth, allocate bandwidth dynamically and follow real-time traffic needs. Newtec Dialog®, for example, can leverage both SCPC and MF-TDMA technologies, depending on traffic conditions, as well as combine the benefits of both by applying our unique Mx-DMA™ technology with the highest spectral efficiency. This ensures that all traffic is accommodated at each remote mobile base station while multiplexing the bandwidth very efficiently between these remotes to decrease the backhaul operating costs. Every subscriber gets the bandwidth he needs at any moment for any application!
