USB WiFi Booster for portability and simple plug-n-play solution

Bear Extender PC is a device that addresses the number one bane of wireless networking—weak or dropped signals. This device is a wireless signal booster (or extender), but unlike many wireless extenders on the market it works on the client side rather than with a Wi-Fi router.
This little device though it has limitations: it only works on the 2.4 GHz band and it drops the connection when it’s 100 feet away from the router. It works ideally at 50-100 feet away from the wireless router.
Bear Extender is an 802.11n long-range wireless adapter that works with Windows. The adapter is a small, flattened device with a clip—it resembles a miniature access point. That clip is for attaching it to a netbook to laptop. I clipped it to an iPad and the grip was quite loose. The thinner the laptop, notebook, or any other wireless client, the looser Bear Extender’s grip. It’s also not an ideal design to attach to smartphones, though I supposed someone with enough intent could manage.

Not only does Bear Extender clip onto a laptop, but it connects via USB from the mini USB port on the device to a USB port on a laptop. If clipping a device which resembles a mini access point doesn’t look odd enough, there’s an approximately 8-inch long external 2 dBi gain antenna that screws onto the adapter. The antenna is designed in such a way as to bypass interference from a laptop’s casing. The entire contraption is sure to elicit a few curious glances in public.
Users can upgrade to a 5 dBi antenna—which is the antenna I used for testing. Bear Extender PC combines two proprietary receivers with a 700mW transmitter capable of theoretical throughput speeds of up to 150 Mbps.
Windows 7 reported a strong, 5 bar wireless signal up until I got to 50 feet away from the router room. Signal strength then dropped to four bars. I was down to 4 bars of wireless strength and crawling internet at 100 feet. Beyond 100 feet, I could no longer connect to the SSID.
With Bear Extender, Windows 7 reported 5 solid signal bars up until 100 feet. At 100 feet, the signal wavered between 3 and 4 bars, but the signal persisted, albeit with a slow connection. I could still see my SSID at 150 feet, but Windows was down to 3 bars and every time I attempted to connect, my connection dropped.
Bear Extender PC can definitely help boost a wireless signal under a few specific conditions: you are only connecting at 2.4 GHz and your signal distance does not exceed 100 feet from a router. Any greater distance than that, are you may still be facing flaky connectivity.
The best use for Bear Extender are smaller spaces with wireless clients that may just need a little extra boost to get wireless to that last bedroom down the hall or into the kitchen. The device’s added bonuses are simple setup and affordability. Bear Extender PC is a worthy 3 stars as a wireless extender.

4-Output Low-Noise HDTV Distribution Amplifier

  • Splitting the signal to multiple TV’s or converter boxes will result in signal loss. The 4-Output HDTV Distribution Amplifier will boost signal strength for reliable picture quality and antenna reception.
  • Designed for both home and professional use, the distribution amplifier can also be used when 50 feet or more of coaxial cable is used from the antenna to the TV or converter box.
  • Distribution Amplifier’s counter this loss by boosting the available signal from the incoming coaxial cable.
  • Our Distribution Amplifier is commonly used in homes and businesses where the antenna will be connected to as many as four TV’s without impacting the signal.
  • Kit includes everything you need to get started
  • Low-Noise 4-Output HDTV Distribution Amplifier
  • Power Supply, 15V DC with Overload Protection
  • One 40in. Coaxial Cable
  • Assembly and Installation Instructions
  • For Indoor and Outdoor Use

  • This distribution amplifier is recommended for indoor use, but they can be used outdoors. For outdoor use, we recommend using a watertight F connector along with weather boots to protect the connections from the environment.
  • Additional tips: If installing outdoors, you will need a power inserter to allow the included power supply to share the coaxial cable connected to the designated output show on the Distribution Amplifier. You should also consider 75 Ohm F-termination caps for any unused outputs.

    WavePoint wireless-communications modules from Free Wave Technologies

    Data is increasingly important for modern society, for management of utilities, oil and gas services, government, military functions, and many other segments of life, and access to data must be reliable and often broadband. Communications now is often between machines as well as humans. To provide such access, the WavePoint wireless-communications modules from Free Wave Technologies are designed to provide machine-to-machine (M2M) wireless communications while operating within a customer’s choice of unlicensed frequency bands at 900 MHz, 2.4 GHz, and 5.0 GHz. These compact radio modules employ orthogonal-frequency-division-multiplex (OFDM) technology to achieve data rates to 200 Mbytes/sec using secure communications based on standard Ethernet and Internet protocols.

    Wave Point base modules provide a choice of frequency range based on a customer’s needs, with excellent propagation characteristics at the lowest frequencies (900 MHz), worldwide availability in the middle frequency range (2.4 GHz), and generous capacity at the highest frequencies (5 GHz).
    Wave Point building blocks include the Wave Point 10e unit, which supports multiple frequency bands and can be configured for as many as four internal Wave Point radio modules, and the single-radio, single-frequency Wave Point 20e unit, for installation at remote end points. The Wave Point 10e can also be used as a relay point in a M2M network or as a Wi-Fi hotspot for a variety of different wireless-communications applications. The Wave Point 10e integrates a pair of RS-232 ports, one RS-485 port, a micro-Universal-Serial-Bus (micro-USB) port, and four RJ-45 Ethernet ports for flexible communications interfaces. The Wave Point 20e, although it contains no micro-USB or serial ports, is equipped with an Ethernet port with power-over-Ethernet (PoE) capability.
    These radios allow the establishment of seal-healing M2M networks with interconnectivity to link to existing communications systems. They are highly secure, based on security protocols using the Advanced Encryption Standard (AES).
    Machines and devices can be wireless connectivity enabled by connecting a standalone M2M communication terminal, by integrating a wireless M2M module, or through integrating wireless chipsets at the design stage. Fully approved and certified standalone M2M communication terminals are designed to fit projects where the available integration time is short, when upgrading existing applications with wireless connectivity or when the production volume is low. Plug and play integration using only cable connectors ensure rapid integration at low cost. For higher volume and space-sensitive applications, integration of M2M modules becomes more attractive despite the longer integration time and needs for end-product certification, because the solution cost per unit is reduced. Although wireless chipset solutions and reference designs are available from several technology providers, the extensive integration and certification efforts involved require very high device production volumes to become cost effective.
    While M2M module sales in Europe have largely been driven by major utility AMM projects, the vehicle telematics market is likely to become the primary application for modules as European consumers continue to adopt aftermarket vehicle tracking and pay-as-you-drive systems in order to reduce insurance premiums. The real potential, however, can be unbleached towards the end of the decade when the eCall initiative to make automatic emergency call services standard for all new passenger cars is expected to be implemented. In North America, consumer M2M services have gained mainstream acceptance with the success of GM’s OnStar safety and security services. Other manufacturers are likely to introduce similar concepts in order to remain competitive. With growing adoption of aftermarket and OEM telematics systems on many markets outside North America and Europe as well, two out of three vehicles sold worldwide in 2011 can be equipped with a telematics system relying on M2M modules.
