Compared with the 2g/3g, 4G the biggest feature is to provide more than 100Mbps peak rate, since the speed can be seconds off 20M of optical fiber fixed network, it is used for voice calls is a piece of cake? It is a pity that the problem arises here.
Since the current LTE network (4G) does not support voice services, so whether it is Td-lte (mobile 4G)

How can the three major carriers innovate their networks when they face the "4G 4G" challenge?
4G development in 2015 is about to enter the fourth quarter. At the latest "LTE Network Innovation Seminar" sponsored by the TD Industry Alliance, a group of the latest statistics published by the Secretary-General of the TD Alliance shows that, with the three major ca
Connect to the ORACLE database through TunnelsSuppose there are two servers on the Internet, one is the application server (Linux), the other is the database server (win2003), and the two servers are in the same LAN (the same network segment ), you can access each other through LAN addresses. Now, you can connect to the application server through ssh, instead of remotely logging on to the database server through mstsc to operate the database. We can use the ssh tool (putty) to configure
Each vertex has a weight of 0 at the beginning of a tree.
Two operations 1. Increase the weight of point I x 2. Calculate the maximum weight on the road from u to v.

Give A matrix A the size of N * N, B = A ^ 1 + A ^ 2 + A ^ 3 + .... whether non-zero items exist in A ^ n and B.
The question can be converted to N vertices numbered 1-N. For any vertices, the question goes through any step to reach u (u is any of all vertices ). In Discrete Mathematics, ma
port to an external address Using the method above, the mapped port can only be bound on the 127.0.0.1 interface. In other words, it can only be accessed by the local machine itself. How can I get other machines to access this port? We can bind this mapped port on the 0.0.0.0 interface by adding the parameter-B 0.0.0.0. You also need to open an option-gatewayports on the SSH server side. By default, it should be open. If it is closed, you can change gatewayports No to gatewayports Yes in/etc/ss
1,gre, the Generic Routing Encapsulation Protocol, the GRE tunnel is a ip-over-ip tunnel that establishes a virtual point-to-point connection, encapsulates the datagram of some network layer protocols through the tunnel, enabling these encapsulated datagrams to be transmitted in the Ipv4/ipv6 network, in tunnel The two ends of the datagram are encapsulated and packaged separately.To create a GRE tunnel on Linux, you need to ip_gre the kernel module, which is the driver for GRE through the IPV4 t
GF's iphone5s port version A1530 Unicom 4G is always unable to connect the problem, the root cause is that there is no 4G switch . The Hong Kong iphone only has a 3G switch. That is, when the 3G is turned on, the 4G signal is found, but only 3G and 2G are turned off. Let the phone signal stay on the 4G signal network.
