Wireless router / repeaters Meraki for the Internet Township

Introduction 

The development of wireless network technology is not the first time raises questions about the prospects - global coverage of public network and the ability to connect to the Internet anywhere and anytime. At a time when powerful corporations are experimenting with long-range Wi-Max and similar technologies, young and ambitious company Meraki Networks has made a bet on a different approach. Rightly judging that is used in most cases, unlimited access to the web (even in Moscow, almost all connections is unlimited, what about Europe or, especially, the U.S.) you can share bandwidth with others, Meraki Networks is building its network on the basis of a successful file-sharing projects. By the way, despite the peculiar name, is an American company and its operating time is a road in the U.S., where broadband access is widespread. A complex network of Meraki Mech is composed of very simple and user-friendly, unpretentious and inexpensive router / repeaters for traditional networks Wi-Fi 802.11 b / g with data rates up to 54 Mbps. Many private networks of continuous coverage area impressive, and there are options not only for the premises, but also for installation in open areas. A pair of Meraki devices, today we'll talk, especially since one of them belongs to the all-weather, and the second - a typical room temperature. 
Meraki Mini Outdoor 

As the name implies, this device requires the use of the street. Housing is safely protected from the weather and the sun's rays to ultraviolet radiation. Scope of delivery rather modest, all placed in a compact high box. 

 The picture shows the device is already attached to the antenna, except the twisted pair to the Meraki Mini Outdoor not connect any cables - power is supplied network cable, using the technology POE. 

 To get started, just need to connect the BP and twisted pair to a small POE-injector, connected to the same network and Ethernet, if it is used in conjunction with the router. 

 In principle, Meraki Mini Outdoor repeater can serve as existing Wi-Fi networks, in this case the Ethernet connection is not required. If you do connect a LAN or ADSL-modem with the corresponding output, the configuration implemented automatically. One of the strengths of all Wi-Fi devices Meraki Networks is their ability to self-autonomous configuration. That is why there is no set of instructions of the device serial number and MAC-address, as well as IP-address which is a web server system configuration. 


Turning to this address (6.1.83.64), the user will see modest page layout settings. To get access to all functions of the device, enter the administrator password. Login corresponds admin password in the form of serial number. To start connecting to the wireless network Meraki and type IP-address. 

If the connection is successful, and the address typed correctly, you'll see the following page: 

While simple, ie with the automatic settings, the user does not need to change anything, do not have any knowledge or information, in fact, go to the web server router is just out of curiosity. What is remarkable - when used in automatic mode as the network, and with a modem connected via Ethernet, all set up and earned without any problems. It also offers a system to register an account on the Meraki project and gain access to additional functionality, up to the cancellation of the "guests" of the network card for traffic. 

Switch gears in the Advanced setup mode and have the opportunity to manually set the number of parameters.

Among the available options there are, of course, the parameters for the Ethernet-connected. 

In a separate group identified available wireless network, you can choose to which of them will be used repeater. The signal is very clearly shown as a line, using Meraki Mini Outdoor possible to significantly increase the radius of coverage of lice home network Wi-Fi. 

In principle, all this should be the case if you require a network outside the home, to put a more simple solution.

Wireless Access Point LevelOne WAP-3100 powered by POE


Introduction 

We have already got used to that large amounts of information quickly and securely transmit without wires. Technologies such as GPRS and Wi-Fi, which seemed almost a fantasy, have become so natural and commonplace, that resident metropolis, not finding any network within range of your device, it would be very surprised. For advanced urban dweller is quite natural to equip the apartment's own access point, even if all sides surrounded by tempting citywide Internet provider network - traffic they still cost quite expensive, reliability of communication with home access point is much higher, and the freedom to configure sometimes very useful. For those home users a very interesting option offers LevelOne. In a series of FREECON from this manufacturer generally quite a lot of successful models of Wi-Fi devices and new Wireless Access Point LevelOne WAP-3100 has the entire series apart from inherent simplicity and reliability of an interesting extension of the functional. More on this later, let's start by tradition with the appearance and configuration. 
Scope of delivery, appearance and features 

As befits a solid company, and LevelOne, of course, notable player in the market of network equipment and data transmission technologies, packaging materials shall be in accordance with corporate style. Design boxes LevelOne WAP-3100 is recognizable and moderately bright. 

 

Depicted on the box apparatus looks unusual, that in itself draws attention. Listing the main features and supported technologies makes the already seriously thinking about buying such an access point, though I must admit that the main parameters of the LevelOne WAP-3100 is quite typical characteristic of many such devices. Scope of delivery is also unlikely to something to surprise, as well as the disappoint in addition to the access point in a box contain: 
User Guide (Multilingual) 
CD-ROM with drivers and software 
standard compact antenna Wi-Fi 
PSU 

The most interesting, of course, the very point of access, with accessories all clear. 

 

Housing LevelOne WAP-3100 is designed in a futuristic-tech style, combining dark gray and silver metallic plastic, has small dimensions and weight at a fairly high strength. The front panel is located only three LEDs glow green: the availability of power indicator, the indicator available wireless connections, as well as the LED turns on when you have a cable to connect the access point to the network. 

 

The back side is also not rich in all sorts of connectors or buttons, there is an antenna jack (RJ45) to connect the network connection for both power and deep recessed Reset button to force reset to default values. 

 

From the bottom of the hull located vents, legs, thanks to which is being ventilated with horizontal installation access point. Envisaged couple of holes for screws to the case where the access point is hung on the wall. 

 

 

Regarding internal filling, apart from the chip from Realtek, and the overall quality factor soldering and assembly point is practically nothing. 

Features Access Point LevelOne WAP-3100 are as follows: 
Compliance with standards 802.11b / g, the data transfer rate up to 54 Mbit / s 
Supports 802.3af PoE - power over Ethernet devices 
1-port Fast Ethernet to connect to the LAN 
Detachable dipole antenna 2dBm 
Broad coverage 
Supports WPA, WPA2, 64/128-bit WEP encryption for the protection of wireless 
Support for different operating modes: Access Point, Wireless Bridge, multipoint wireless bridge, repeater and WDS Bridge 
A comprehensive display on the front panel of the device, the status of the device and found errors in the operation 
Compact design for convenient desktop or wall-mounted location unit 
Simple installation and configuration process 
Web-based interface configuration 

Perhaps it is worth noting three important points: support for technology PoE - Power over Ethernet, ie powered by a network interface, the ability to work as an access point, repeater, or bridge, as well as ease of configuration. Other characteristics are typical of the access points and do not require focusing. We will understand with the above three points. With all modes clear or LevelOne WAP-3100 is simply an access point, or retransmits the signal as is or convert it at work in bridge mode. Intriguing PoE technology allows us not to use the attached to the device power supply and receive power over twisted pair, along with the data. The technology is not very common and unusual, although the standard PoE is already about 5 years. Order to point LevelOne WAP-3100 has earned, eating from the Ethernet, you must use PoE-compliant switch or hub. As part of the standard devices are divided into two groups, PSE (Power Source Equipment - equipment-power source) and the PD (Powered Device, a device receiving food). For access points, plays the role of recipients, ie PD - this is valid not only for the specific model LevelOne WAP-3100, this general rule. Finally, a convenient and simple interface - this is discussed in the next chapter

Multi-3G-router LevelOne WBR-3800

Introduction 

Wireless network technology came into use, so firmly that no longer surprised by the presence of WiFi in cafes, and absence. The capital is almost entirely covered with the largest providers of wireless networks, and in apartment buildings, if you include search networks WiFi, then there is 5.6 units of access points, and it is only visible from the network, and a short distance, as the walls and ceilings are strongly attenuated signal. Of course, conveniently, when the network is always somewhere nearby, accessible by pressing a few buttons, and provides good speed. But do not forget that the capital's metropolitan regions are most attractive to providers and coverage are the best, and prices for the most lucrative traffic. Even the closest urban situation can be quite the opposite: you either wireless or cable, and if there is an opportunity for the ADSL-connection, the MB of data is so much like him to tell the pigeons. 

Fortunately, it no longer seems utopian or wasteful exercise using cellular network operators to connect to the Internet, all leading companies have special rate plans, there is in selling their equipment - modems, and once in the open field with a laptop is quite possible to check email, look for that on the network or even call through Internet channels on another continent, today's rate can even watch videos. Use a modem as the main channel still expensive, and using the home or small office with multiple computers is a problem of sharing the channel. Make a cellular modem, and fallback to work with him for several PC allows such an interesting device as a multi-3G-router LevelOne WBR-3800, and this device has a name MobilSpot, reflecting its essence. With capabilities and features of this router, we now take a look in more detail, traditionally begin with a set of delivery and performance. 
Scope of delivery, appearance and features of the router LevelOne WBR-3800 

Packaging LevelOne WBR-3800 is decorated in the traditional style LevelOne, compact size and with logos wireless technologies and a list of core functions to inform about the possibilities of your device. 

 

Inside the box are the following items: 
Sam router LevelOne WBR-3800 
Antenna 
Stand for vertical installation of the device 
Mains power adapter, 
Ethernet cable to connect to a computer, network hub or modem, 
Quick Installation Guide, 
CD-ROM with a complete user manual and software. 

Equipment can not be called outstanding, all components are necessary and are supplied with routers and access points, noting that unless you can stand, through which a square flat box LevelOne WBR-3800 can be installed on the end and save desk space. 

 

With this installation option, the device is flat black with a stylish orange trim not only takes up less space, but also allows you to direct the antenna in any direction, but hardly any difference in connection quality will be noticeably depend on the angle of the antenna. 

Much more interesting in this case, the location of slots. Yes, a wireless router LevelOne WBR-3800 is equipped with a slot in the router you can install the modem, made in a notebook format Card Bus. These modems operating over cellular networks, usually have their own antennas and their position in space as time is important, so that setting up a router slot has the additional advantage. 

 

Ability to use a 3G modem and provide for multiple users work through this connection - in fact, the unique ability LevelOne WBR-3800, it would be unfair if it could use only the owners of modems in a form factor Card Bus. If your modem uses a USB-connected to the computer, do not worry - with this router and it will work. 

 

At the rear of the chassis are all the connectors, including USB to connect 3G-modem and two network ports: one to connect the router to the DSL modem, the other - for the cable connecting a PC, in case the WiFi for one reason or another can not be used . 

The front side is not equipped with any ports or buttons, it is distinguished only 4 lights in the right half, they show a connection 3G, LAN, WAN and WLAN. 

Short list of possibilities LevelOne WBR-3800 (MobilSpot)

8-port GSM-gateway ALLVoIP AV3803

Anyone who is used to monitor spending and generally know how to count money, he knows that mobile communication is used in an uncontrolled, on occasion, and without, can become a very significant expenditure, especially in a company-wide. When it comes to corporate use of mobile communication, it is considered that its cost should worry about the company itself, choosing the operator, the most appropriate charging scheme, and instructing employees on conditions of use of telephone for personal purposes. Of course, it gives some results, but by no means suggests that communication costs are optimized and can not be radically reduced. Probably every occasion to use the services of "alternative" long-distance and international communication. By purchasing a card and call the number listed on it is possible to talk of, say, from Moscow to Vladivostok on the local rate plus rate of the company, issued the card (using IP-telephony to transfer your call), which ultimately turns out to be cheaper than the tariff fixed-line operator, or the more mobile.

The benefit is obvious, that's just not very convenient to use - and the process of dialing, and the need to purchase the card, again the choice of the company providing such services (IP-telephony operators in recent years far more than the companies that provide wireline or wireless connection). In general, we need to perform a set of actions, and there is quite a logical idea, why for IP-telephony have to pay significantly more than the cost traffic, unless you arrange their own voice? Without specialized solutions do this, perhaps we could, but it is very difficult and unprofitable, and therefore can hardly be neglected proposed equipment, the more that it is available, easy to deploy and use, simply integrated into the corporate infrastructure. It says everything about the GSM-gateway ALLVoIP AV3803, the further the story will follow this decision.
Scope of delivery, the main characteristics and features

Appearance ALLVoIP AV3803 immediately gives a professional designation device. Designer delights can be considered unless the choice of colors for painting the metal case. Small in size, it is almost completely painted a pleasant shade of aquamarine, only the front panel and back side of the light, almost white. The front panel contains eight slots for SIM-cards, they are placed in four groups of two slots and are equipped with LED indication of the link. Another indicator in the lower right corner of the panel indicates the presence or absence of food.

I must say that in a quiet room on the availability of food excellent report and the noise of the fans, two of them and both are located on the back of the chassis. Between the fans are connectors for external antennas, they are two, despite the fact that the device is set up to 8 SIM-cards. Thanks to the built-adder, two antennas is more than enough to serve 8 transmitters.

On the left, in the well is located connector for power supply and port network interface through which the gateway ALLVoIP AV3803 is connected to the corporate network and the Internet.

Complete set of the device to expectations: no nonsense, a kind of necessary and sufficient equipment. In a modest gray box contains the following components:
Sam gateway ALLVoIP AV3803,
Power supply
Power cable,
Network cable with RJ-45,
Two small antennas GSM.

It is noteworthy that in a set of 2 antennas, the number of inputs for connection, although the channels at the gateway 8. I must say, ALLVoIP AV3803 quite effectively uses these small antennas and provides reception quality is much better than conventional mobile phones. Where the mobile phone shows the 1.2 "sticks" to the signal strength indicator, GSM-gateway works confidently and evaluates the signal as a good and stable. Antennas may seem fragile, because they have a small footprint, but everything is simple - they are magnetic and can be safely installed on the body lock or any more stable steel facility.

To start with ALLVoIP AV3803, you must install the SIM-card (or cards, up to 8, which side of their set - shown in the picture-prompt for each pair of slots), connect the network interface to the LAN or to configure, directly to your computer, connect the antenna and connect to ALLVoIP AV3803 power adapter. Fans will begin to rotate, creating a rather loud but not annoying hum, in principle, if the gateway does not put in the server, and a working office, interfere with the work he will not, though, the room more comfortable will do. LEDs on the channels of the link will flash on when a communication (calls to any gateway of the rooms) to include an indicator of the channel. You are ready to set up for later use, how to do it - we now detail closer look.

Software for IP telephony IP PBX from Mototelecom

Introduction 

There will be told trivial thing, but no such entry is necessary. So, this is familiar to all true that possessing information - possess situation. Information in our day - a dime a dozen, and one of the criteria of its quality is the speed and accessibility. What these arguments? Moreover, without reliable running, high-quality and manageable communications business rivals, who have been established as befits us. Today we talk about telephony, because it remains the most important channel of communication. If the quality and reliability traditionally paid attention to - select a proven provider of reliable, good lines, including the spare, then on the controllability remember when to change something already too late. In fact, this issue can be closed by selecting the optimal PBX, but what they are and what can be demanded of them - is quite a big issue. Today we'll talk about IP PBX Mototelecom, as one of the most functional solutions and bright representative class of software PBX. 
Iron against software 

Before turning to the specific software PBX, remember what kinds of PBX office in general are. First, of course, traditional hardware PBX. They are quite expensive, but the most traditional solution. A wide range of opportunities "iron" ATE is very expensive. 

Software solutions can have the same set of functions, but their price is much lower. In addition, the ATS program has many advantages. First, the ATS program management is carried out through the web-interface, which can run any employee who has basic computer skills. In addition, it allows you to configure and work with the PBX software remotely. 

Second, software solutions can work without telephone lines, on the infrastructure of computer networks, using IP-telephony. If necessary, using VOIP-gateway or CTI-PBX, such fees can easily interfaces with the usual lines, but the redirection of traffic to the IP-TV allows you to save in the operation of the exchange. In the workplace, you can use hardware SIP phones, with the choice of the manufacturer and model no restrictions, you can use a computer with appropriate software and a headset. 

Thirdly, they provide a very flexible call management, call processing, and these types of voice communication, such as conferences. 

Fourth, the PBX software is cheaper and does not require the introduction of any special work, it is sufficient availability of computer network. 

In order not to seem that the shortcomings of such solutions is not entirely necessary to mention the weaknesses: in particular, the dependence on the server. However, the risk can be minimized through regular backups and the acquisition of additional equipment in the event of failure of the primary server. 
IP-PBX Mototelecom: Overview 

Let's start with what is traditionally the most important for PBX - with call processing, inbound and outbound. 
The absence of any restrictions on the number and type of incoming lines, and this means that there is no need to purchase any additional licenses. At the same time to establish communication as easy as to make ordinary phone calls. 
Service outside numbers to define the system for incoming calls to external numbers - the system is very flexible and allows you to customize the processing optimally. 
Handlers "non-response," busy "and" not online "- you can define actions on almost all occasions. 

 
Ability to play when a call comes in music instead of beeps - the familiar function and no apparent utility, but without it they can. 

 
Three types of virtual rooms: a chain of calls, group calls and random chain 

 
Ability to intercept the call and create an unlimited number of groups of interception. 
Two ways to transfer calls to another subscriber: "blind" transfer and "deferred". 
Connect additional external communication channels - through VOIP-gateway or the CTI-boards can connect traditional telephone channels. 
Routing outgoing calls and the priority communication channels - it is necessary to optimize the traffic in terms of cost, as well as the network load 

 
Ability to set rules for outgoing calls 
Ability to choose the desired channel for outgoing calls - in the case when you need to make a call using a specific channel, a software IP PBX Mototelecom can do it. 
Ability to set an outgoing call number, which will be defined as the number of the caller - this feature is useful when outgoing calls are sent over one channel, and receive incoming preferably on another without creating a subscriber on the other side of confusion with two rooms - it will use and see only one. 

Perhaps the highlight and a separate talk is about the interactive voice response, IP PBX software Mototelecom provides very good opportunities for the management of such messages. 
No restrictions on the number of scenarios and algorithms for the menu, it means that you can create an entire message structure, reproducing, depending on the performance of certain conditions (date, time line, number, etc.) 

 
Call forwarding in the case of non-response or if the line is busy - you can configure call forwarding in the various contexts. 
Ability to obtain information from databases for automatic responses to customer inquiries. 
Ability to set to music or voice messages in Hold mode, and switching the call. 
The ability to create queues on the subscriber number. 
Ability to establish periodic IVR. 
Ability to set filters on the IVR-time parameters 

As we see, manage voice messages / responses can be so flexible that you can provide any situation. 
For today's business is characterized by numerous meetings, including telephone and IP PBX Mototelecom provides a conference connection, ever more in demand: 

 
No restrictions on the number of concurrent conferences and parties 
Cascading - You can create as many conferences as necessary, to ensure the privacy of communication - is enough to set a password for access. 
Planner conferences with the function of informing the participants - a very handy feature that allows you to better plan the working time and just do not forget about the conference. 
Templates conferences. 
Ability to connect to external audio-subscribers 
Recording conferences and monitoring. 

With IP PBX Mototelecom available and voice mail, so loved by mobile operators. Using IP PBX Mototelecom can leave a message if no answer or its busy.

Office IP PBX AllVoIP AV80404-IPPBX - review and testing

Introduction

Four conventional PBX pass with frightful rapidity. In order to make such a conclusion, it suffices to find a brief list of possible IP-PBX: digital technologies and the development of network infrastructure allows them to push the traditional devices on all fronts. Not only is a cheap and reliable communication, based on the protocol IP, can reduce the use of traditional telephony, if not totally abandon it. Now become habitual and, therefore, needed, and additional features that were previously and did not exist. It may also simplify the cabling infrastructure office, which is also important. In general, the reasons for which we propose to draw attention to the PBX AllVoIP AV80404 - abound. Let's see whether they are real.
The appearance, specifications and equipment

Packaging equipment and PBX AllVoIP AV80404 - rather modest, in a small brown box are:
Itself ATS AllVoIP AV80404
Power supply from 220V
CD-ROM with User Manual

This PBX can register up to 30 users, each of whom will have access to all the functions necessary for communications in the modern office. AllVoIP AV80404 allows you to control the VoIP traffic control connections are connected SIP-devices (gateways, IP-phones, including software , SIP-adapters), to realize the conference and IVR, as well as to integrate into the system up to 4 urban lines through the ports of FXO.

What is noteworthy - this is an opportunity to unite into a single geographically separated offices, communication between staff members located in different parts of the country is carried out as easily as if they were sitting in adjacent rooms, and remote users can receive and access to urban lines of the head office .

Perhaps, the wealth of opportunities and benefits AllVoIP AV80404 not cause the slightest doubt, it remains to understand how realistic all this arsenal to use: an inexperienced user such a system may seem complicated, but in reality, all management is carried out through a convenient and intuitive Web interface, which will describe in detail.
Configuration, management and use AllVoIP AV80404

For a start, to gain access to management, you need to connect IP-PBX AllVoIP AV80404 to the local network. Note that by default, this device is assigned IP-address 192.168.1.100 (port WAN), so that it is desirable that at the time of the first connection of the address was available. In passing on it in the browser the user sees the login prompt in the system. Enter your login and password, the default (specified in the user manual), we see the main menu IPPBX AllVoIP AV80404:



The ideology of the menu is simple and visual, in the left column - paragraphs and subparagraphs of the menu system AllVoIP AV80404, a wide central column - the content selected at this time point in the right column - help for the moment.

In the section "Numbers" can be set or edit the list of internal numbers, to indicate what the user what number belongs to, set a password for access to the most number (you can change jobs, but keep the same number), and voice mail, set the dialing rules and relevant the user analog phone line, if any. It also indicates which services and protocols should be available number.

On the next page, the corresponding item "Channels" can be done setting the parameters of external connections, PSTN or VoIP, to the appropriate service provider providing services to office.
