The traditional LTE solution requires a huge centralized EPC, which dramatically increases the initial investment for fixed wireless business. And old fashioned eNB is also large and heavy, with a bigger footprint and costly installation.
Traditional LTE solution is very complex due to the requirements from mobile business, which is not necessary for fixed wireless scenarios and brings an additional challenge to maintenance teams of wireless ISPs.
High cost of backhaul
The standard architecture of LTE is with a centralized EPC, which needs to route all the traffic to a centralized node and then to the Internet. However, the backhauling cost is high for such architecture, since it requires good bandwidth and quality of transmission
Hybrid Solar Power system
Lack of value added services in traditional LTE To remain competitive in the market and seize high value enterprise customers, the best solution is to be able to seamlessly migrate these customers while supporting the network’s L2 and L3 modes of intranet operations. However, layer 2 VPN functions cannot be supported solely by the LTE standard and this will pose a great challenge for wireless broadband operators to sign up enterprise customers.
