C) 802. 11H to make 802. 11A Radio transmitting power and channel selection are better controlled.
D) 802. 11I focus on 802 increase. 11 system security and confidentiality issues.
Like the MBS in GHz, the problem with wireless LAN access is that each access point or base station can reach a very small distance, about M, the outdoor environment is good in the case of only hundreds of meters. This means that wireless
Multiple Access
Frequency division, sometimes referred to as the channel, is to divide the entire distribution of the spectrum into a number of single radio channels (transmit and receive carrier pairs), each channel can transmit a voice or control information. Under the control of the system, any user can access any one of these channels. Analog cellular system is a typical example of FDMA structure, digital ce

Iv. typical application fields of LMDS system
(1) Application of LMDS in data communication network
As the access part of the data communication network, the LMDS system plays the role of connecting the Service node interface and the user network interface. This application is the traditional telecom operators on the basis of existing networks, as a complementary means of optical fiber access, in the short term to meet user demand for broadband serv
If your company is in the Tempe City of Arizona, State, you now face the choice of spending money on large area Wi-Fi or cellular digital services like 1X ev-do.
Wireless network problems As with most other things, finding the answer is not easy. Maybe you need to pay for both of these, depending on your end-user needs and the applications they use.
Currently, Wi-Fi providers are already using low monthly rents and high bandwidth to woo customers, a
HSDPA (High speed downlink packet access) is used to realize high speed downlink data service of WCDMA network, which can make the downlink data rate reach 8~10mbps, which is regarded as the main solution of the 3G era. The data rate can reach 20Mbps in the HSDPA system with multiple and multiple out (MIMO) technology. The emergence of HSDPA has aroused great concern of the industry. As the following evolution technology of WCDMA system, many key technologies in HSDPA are similar to CDMA20001XEV
reached 108, WCDMA style has been a relatively many improvements. At present, the commercial system, from the WCDMA angle is mainly based on F4, cellular mobile camp including broadband access, different camps competition between the comparison, but also to promote the 3G technology and standards continue to develop. CDMA2000 's camp is in the position of comparative advantage, as 1X itself can provide a user rate of up to 80K. WCDMA itself and the E

When talking about Unified Communication, many friends first think of mobile communication. Indeed, in the concept of Unified Communication, mobile communication technology is indeed included. But not all of them. We will introduce this knowledge in detail through this article for mobile Unified Communication.
Mobile Unified Communication Elements
With the wide recognition of the benefits of mobility, there are a wide variety of mobile communication solutions available. The mobile Unified Commun
Access Network Technology-Wireless Access
Wireless access can be divided into mobile access and fixed access. Mobile access can be divided into two types: high speed and low speed. High-speed mobile access is generally available in cellular systems, satellite mobile communication systems, and cluster systems. Low-speed access systems can use PGN micro-cells and micro-cells, such as cdma will, PACS, and PHS.
Fixed access refers to wireless access from
