This site attempts to compile radios and radio accessories for 4g 802.16e WiMax at 2.5- 2.7GHz. In the U.S this is offered by Clear Wireless, LLC under different brands such as Clear, Sprint 4G, Comcast High-Speed 2go etc. To learn more about long-range wireless solutions and in particular Point-to-Point, Point-to-Multipoint or mesh wireless solutions please contact us.
These antennas PRIMARY GOAL is to improve In-door coverage when outdoor coverage is sufficient (and they do this very well!). They are NOT designed to miraculously provide coverage in areas where even the outdoor signal is extremely weak. The articles above explains how to determine if you are a good candidate for these antennas. Do contact us if you are unsure.
It is the users responsibility to ensure that any client antennas used don't cause the radiated power to exceed regulatory limits. Remember that too much directional gain is just as bad as too little. For help in RF link budget analysis please ask.

Clearwire CLEAR™ Brand Modems
CLEAR WiMax offers target download speeds of 4Mbps and upload speeds of 500 Kbps. This is the first commercial large-scale 4G network in the U.S. Note that Received Signal Strength (RSS) or more correctly received signal-to-noise ratio (SNR) and transmit power or Effective Isotropic Radiated Power (EIRP) are NOT the only cause of low datarates. Furthermore MIMO antenna spatial diversity used in WiMax to combat multipath fading and improve performance should not be ignored when adding high gain antennas. Contact us for assistance or visit our forums to discuss.
This USB modem has no external antenna ports but may access antenna connector stub on the PCB (disconnect printed antennas, connect pigtail and coaxial cable to outdoor antenna)
Includes external antenna ports to connect WiMax band antennas with appropriate pigtail.
Clear 4G+ Series S USB Modem (Sierra Wireless AirCard 250U)
Dual mode 3G EVDO RevA (800/1900 MHz) & 4G WiMax (2500-2700 MHz). Includes 180degree swivel, integrated GPS and TS9 External Antenna connector (NOTE: - Includes 2 external antenna ports for MIMO diversity. See forum discussions on implications)
Like other WiMax USB dongles this modem includes two internal antennas as well as two external antenna ports for MIMO diversity. ANT#1 internal antenna is a PIFA style (Inverted F-Antenna) and ANT#2 is a reciprocal notch. Peak isotropic gain is 2.12dBi. Note also there's no uplink/reverse-channel MIMO so for heavy upload applications less dependent on MIMO diversity gain or MIMO spatial multiplexing.
Since no MIMO in 3G NEED to use primary antenna port only. Also if only using one external antenna for 4G need to put it in primary port. See forums discussion on when you can get away with one external antenna for 4G.
New product from Ubee Interactive. Provides improved antenna performance and swivel design to allow for 0-180o swivel for convenience and improved radio performance where needed. The USB Doc accessory allows convenient placement of Modem+Dock in areas with better signal strength.
Note supports 1TX/2RX MIMO diversity (only one TX antenna at a time).

Antenna pigtail for the USBw 200 USB (Clear 4G USB Modem) modem is here or get antenna and pigtail as part of kit
CLEAR USB Modem
Motorola USBw 100 is a Wave 2 Ready triband indoor WiMax modem with capability to operate in 2.3, 2.5 and 3.5GHz bands (Clear WiMax currently deployed in 2.5GHz band)
Hint: Consider converting WiMax to WiFi using a 4G router such as Cradlepoint routers and locating the Router + WiMax USB Modem pair where you have the best received signal strength (RSS). If outdoors consider weatherized enclosures. If need the resulting WiFi to cover large areas see range-extention tecshniques.
Step3: use a low-loss (400-series recommended) coaxial cable for required length.
Step4: Select appropriate 2.5GHz WiMax antenna below (NOTE: for antennas with N-Female ports they directly connect to the cable selected in step3. For antennas with SMA-female port you need a SMA-Male to N-Female adapter.
Series M CLEAR CPE Modem
External Antenna:
Doesn't have an external antenna port but has a Murata SWD antenna connector/switch test port on the PCB that can support an external antenna.
Consider using the Gemtek WIXS-167 Outdoor CPE for improved indoor signal reception. NOTE- Verify with Clearwire if a "generic" Wave2 compliant WiMax modem may be provisioned on their network before purchase.
You could possibly attach an external antenna using a U.FL to N-Female pigtail, N-Male/N-Male low loss LMR400 coaxial cable and our Wimax antennas but this requires opening up the case, detaching the internal antennas, drilling through the case - it goes without saying that this voids the warranty.
CLEAR CPE Modem
Motorola wi4 CPE i150 is 802.16e WiMAX Forum Wave 2 certification ready.
Hint: To obtain best RSS received signal strength consider locating CPE in area with strongest RSS such as outdoors and boosting WiFi instead. Consider weatherized enclosures and range-extension techniques.
Clearwires Motorola CPE Modem has NO external antenna connector available (only 2 internal 7dBi antennas). As such you may use the coupler such as used above for the USB modem and the 2.5GHz antennas connected to appropriate cables similar to the case for the USB modem above. However Rfwel has NOT tested this setup and verified that the performance is not degraded by doing this.
To network multiple devices use standard LAN switch, router or Wireless AP.
Sprint 4G Modems
Sprint is a MVNO (Mobile Virtual Network Operator) of Clearwire and owns 51% of Clear 4G network. The coverage and network performance of Sprint 4G is thus identical to that of Clear.
The Sierra Wireless Overdrive converts 3G EVDO or 4G WiMax into WiFi enabling up to 5 WiFi connected devices and 3 concurrent users to share the same high speed data connection. FCC ID: N7N-MHS801. Key features include:
Weight: 4.51 oz
Dimensions: 3.14"x3.14"x0.61"
Battery capacity: 1830 mAH
GPS Navigation Enabled
Memory card slot and 16GB of Shared Storage
Antenna: internal PIFA (planar inverted-F antenna) with -0.5dBi gain @2.5GHz & 0dBi @1.9GHz
NOT COMPATIBLE with the Universal Coupler Antenna Kit!
U301 3G/4G USB Modem
Dual mode EVDO RevA (3G) and WiMax (4G) with support for MAC OS (Note the U300 doesnt support MAC as of 1/21/10). FCC ID: TARCMU-301 (c-motech) Key features include:
Weight:1.25 oz
Compatibility: Microsoft Windows® XP, Windows Vista® and Windows 7
Mac OS X version 10.4, 10.5 and 10.6
We DO NOT RECOMMEND use of the Universal Coupler Antenna Kit for the U301. We recommend those facing poor in-building coverage to switch to either the Sierra 250U or the PXU1900 modem or any other modem with an external antenna port.
The Franklin Wireless U300 USB Modem for Sprint lets you connect your PC machine to the Internet nationwide on the Sprint PCS network. The high-speed EVDO Rev A network delivers data downloads of up to 3.1 Mbps and upload speeds of 1.8 Mbps. And, the Franklin Wireless U300 offers an additional bonus - access to next generation WiMax connectivity. Finally, this broadband card includes built-in GPS for location-based services right on your laptop more
NOTE that since the Franklin U300 doesn't have an external antenna port the kits above rely on a universal passive coupler that is velcro'd to the USB modem. This is NOT the most optimal solution and will only provide a marginal boost due to the coupling losses. Furthermore by using this coupler one is unable to isolate the signals going to the two internal integrated antennas so you end up losing MIMO diversity & coding gain. We STRONGLY recommend those facing in-building coverage issues to switch to either the Sierra 250U or the PXU1900 modem or any other modem with an external antenna port.
