system) must be upgraded to a higher frequency band, so as to obtain greater bandwidth. High-frequency transmission requires a rigorous visual transmission (LOS), while the Microcell in the scheme works in a lower 2.4GHz, essentially avoiding visual transmission. and work in the 2.4GHZ Low frequency Wireless LAN terminal price is cheaper than LMDS terminal price, do not need microwave antenna to receive signals, so that fully consider the user's economic affordability. through the use of doub

6. read-only domain controller (read-only domains controllers)
If your business has branch offices or subsidiaries, the new version of the server contains a read-only dynamic directory (read-only Active directory, ROAD) feature that may be of interest to you, which ensures that all businesses are centralized.
Ideally, all domain controllers should be loc
to 108Mbps, even up to 500Mbps. Thanks to Mimo OFDM, which combines MIMO with OFDM (Orthogonal Frequency Division multiplexing) technology, this technology not only improves the quality of wireless transmission, but also greatly improves the transmission rate.
Application prospects: 802.11N will allow WLAN transmission rate of 10 times times the current rate of transmission, and can support high-quality voice, video transmission, which means that people can use Wi-Fi mobile phones in office sp
BitLocker-driven encryption is a key new security feature in Windows Server 2008 that protects servers in branch offices, as well as Windows Vista Enterprise and Windows Vista Ultimate versions, for roaming users Provides protection for client computers and mobile computers. BitLocker encrypts disk-driven content, protects people running another operating system, or runs other software tools, from file destruction and system protection or offline file

Traditionally, the firewall implements the boundary security by maintaining the static control of all connections between the connected network segments. Today, more and more customers are looking for firewalls that provide VPN services in addition to access control. With VPNs, remote users or distributed branch offices can access the enterprise network at a lower cost, while using Internet access can significantly reduce the cost of telecommunicatio
Here I only discuss the situation of single site, about multi-site next topic again discuss. The so-called single site, only the entire forest structure in a geographical location, such as in Beijing. The interior is connected by high-speed lines such as 100M. The default site name is Default-first-site-name. You can view it through the ad sites and services component.
First, why do you create multiple domains in a forest?

For some small offices, generally use a desktop to do file sharing server, but this too occupy space, and power consumption is very large, a year down the cost of electricity is estimated to thousands of dollars, it is not cost-effective, so some manufacturers designed a simple Low-power file sharing server, you can directly to the hard disk, The data on the USB storage device is shared through the internal network, and we have received a produ

Experiment Request:
1. Branch to the headquarters or other areas to use R1 as the main link, R2 become a standby link
2.IP the hierarchy of address, to be able to achieve routing summary
3. The branch of the router as a stub node, to avoid other routers to send
The telephone network is the communication network that open the telephone energy for the general User Service. The earliest form of telephone communication is only two telephones, which are connected by wires, however, when the number of telephone users in a region to increase the number of users can 22 call each other, you need to set up a telephone exchange, by the switch to complete the connection of any two users, then formed a switch as the center of a single bureau system telephone networ
management method is difficult to handle large-scale database management across the region, Therefore, the distributed database can be used to store and manage population information data. Combined with the business characteristics of Hainan Special Economic Zone, the population size is small, the municipal branch offices do not participate in population information management, so the Hainan Province population Information Data management can use the
The technology of Cisco ADSL Router is very advanced. At the same time, compared with other types of ADSL Router, its products are still very advantageous. Cisco ADSL Router combines Cisco IOS®R's technical advantages provide business-level service functions for small offices and remote office staff of the company.
It supports different levels of services, high-quality Integrated Voice/Data transmission, and business-level security features, can rapid
I believe that many users are most concerned about their performance when purchasing a Wireless Broadband Router. Here we mainly introduce the three features of the Dlink DIR Wireless Broadband Router, in the past, due to technical restrictions, 11G may not be able to achieve full wireless coverage for the family.
With the emergence of 11n, the transmission distance and the penetration of wireless signals have been significantly improved, which can fully meet the wireless coverage of current th

related design. Of course, many of the other related systems in OFBiz also apply these table structures, which means that they are suitable for general industry and system versatility, thanks to the high level of abstraction in this design. It can describe any organization, individual, their address information, the relationship between them. In particular, the design of the member "relationship" table is very similar to the model of responsibility referred to in the "Analysis mode":Therefore,
