VULCAN Vs MERCURY TECHNOLOGICAL DIFFERENCES AND APPLICATIONS

For connections of type:  Point to Point (radio link between two devices).  Point to Multi-Point. For connections of type:  Point to Point.  Point to Multi-Point.  Access Point (AP).  Wireless client. VULCANMERCURY

VULCANMERCURY TDMA (Time Division Multiple Access):  Data coming from multiple sessions and with a specific period of time is transmitted by the media. TDD (Time Division Duplex):  By means of the same frequency channel, transmission and reception are made in different periods of time. CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance):  This media access method is similar to the use of HUB equipment. The devices implementing this technology must “listen” the radiofrequency channel before transmitting the data required for communication.  Collision avoidance is required.

 It is not compatible with Wi-Fi products because the protocols of Data Link Layer and Physical Layer are different.  It is compatible with Wi-Fi products.  Under IEEE a/b/g standard. VULCANMERCURY

 It keeps the data rate by session at a limited faraway distance.  It works with DRS (Dynamic Rate Switching).  As the wireless client distances from the AP, the data rate adjusts to low speeds. VULCANMERCURY

 The devices can operate in the frequency bands ranging from 450 MHz to 7 GHz.  Special custom-made frequencies available under request.  The devices can operate in the 2.4 GHz ISM and 5 GHz UNII-1, UNII-2, and UNII-3 frequency bands. VULCANMERCURY

 Multiple sessions can be managed at the same time by means of the TDMA/TDD technology.  Each session is assigned a data rate.  Sessions compete for accessing the shared media.  QoS can be enabled for multimedia sessions. VULCANMERCURY

 Mobile clients can move around the cell up to 80 Km/h without losing synchronism.  Mobile clients can move (in certain cases) around the cell, but at low speeds.  It is not recommended for connecting mobile devices in motor vehicles. VULCAN MERCURY

 Almost-Non-Line-Of-Sight (ANLOS). High power VULCAN UHF Radios do not require line of sight, with the exception of very extreme conditions.  VULCAN Radios in 2.4GHz and 5GHz do require line of sight for operation.  Site Survey in the location is recommended.  Line-Of-Sight (LOS). among the devices to be linked wirelessly is required, because they work in very high frequencies.  Site Survey in the location in recommended. VULCAN MERCURY

 Average cost.  Less expensive than VULCAN devices. VULCANMERCURY

 VULCAN CPEs or client devices have an average cost.  MERCURY CPEs or client devices are very economical. VULCANMERCURY

 It integrates the FEC technique for reliable delivery of data, and allows the correction of corrupted “bits” by means of correlation algorithms with the redundant “bits”.  The FEC technique is used for error control in the data transmission over noisy an unreliable communication channels  It does not implement the FEC technique. VULCANMERCURY

 VULCAN UHF radios can be configured for 5 and 10MHz bandwidths.  VULCAN Radios operating in high frequencies con operate with bandwidth up to 40MHz.  In 2.4 GHz models, the bandwidth available is 22 MHz.  5 GHz models of radios use 20 MHz bandwidth. Except the LP-288ai in Turbo Mode which support 5/10/20/40MHz bandwidth. VULCANMERCURY

 These devices keep the data rate (Mbps) stable at faraway distances.  Because of DRS, these devices vary the data rate and adjust it depending on the quality level of the wireless signal. VULCANMERCURY

Power sources available:  12 VDC, 24 VDC, and 48 VDC.  120~240 VAC.  Integrated proprietary PoE technology. Power sources available:  24VDC and 48 VDC.  120~240 VAC.  Integrated proprietary PoE technology. VULCANMERCURY

 Full-Duplex sessions are simulated by means of TDMA/TDD.  Half-Duplex sessions only. VULCANMERCURY

 PtP and PtmP links for long distance.  Last mile services.  Backhaul.  Telemonitoring.  Multi-sessions links with QoS.  Highly mobile networks.  Links with no line-of-sight required.  Business, industrial, and military applications.  DC mobile versions.  Wi-Fi cells.  Last mile service.  Hotspot.  Internet access.  Networks of free frequency bands.  Line-of-sight required for optimal performance.  Repeating points and wireless bridges.  Applications for small, medium, and large companies.
