If your staff, guests or warehouse team are on EE or Vodafone and their phones show Band 7 at 2600MHz, the L2000 is the box that rebuilds that signal across a full 2000m2 floor plate for 200 simultaneous users. It grabs the weak outdoor signal with a 7dBi omni antenna, amplifies it with 70dB uplink and 75dB downlink gain, and rebroadcasts it indoors through a 7dBi panel antenna at up to 27dBm output power.

This guide explains exactly why EE and Vodafone rely on Band 7 in cities, what the capacity advantage of 2600MHz really means, how the L2000 solves the building penetration problem, what VoLTE HD audio adds, how the 7dBi omni and 7dBi panel antennas work together, how to cable and install the unit in 20 to 25 minutes, what the annual electricity bill looks like, how the L2000 compares with the L1000 at GBP535.00 and the C2000 at the same GBP835.00, and what rural EE customers should do when Band 7 barely reaches their roof.

EE and Vodafone concentrate their highest-capacity 4G on Band 7 at 2600MHz because it carries 20MHz wide channels. In spectrum terms, 20MHz is the widest single block either operator can deploy on one band, and wider channels mean more simultaneous data throughput per cell. This is the band that delivers 30 to 80Mbps in dense urban cells, which is why your phone camps on 2600MHz the moment you walk into a city centre.

The downside is that 2600MHz is a high frequency. High-frequency waves are short, directional and easily blocked by concrete, steel, low-E glass and insulated cladding. The exact same band that flies through open air dies inside a modern office building. This is the core problem the L2000 exists to solve.

Band 7 offers more throughput per cell than Band 20 or Band 3, which is why EE and Vodafone load it with data-heavy smartphone traffic. When 200 guests in a hotel all open their phones at breakfast, Band 7 can carry that traffic without the cell collapsing. On Band 20, the same 200 users would see speeds crawl to 2 to 5Mbps because the channel is only 10MHz wide.

The tradeoff of 2600MHz is penetration. 2600MHz loses 15 to 25dB through a concrete slab and reflects off low-E glass almost as strongly as it reflects heat. The L2000 solves this by not trying to push the signal through the building at all. Instead, it grabs the outdoor signal with a 7dBi omni antenna mounted on the roof or exterior wall, amplifies it with 75dB downlink gain, and rebroadcasts it indoors through a 7dBi panel antenna at 27dBm. The building's walls are bypassed, not defeated.

Pros of this approach: works through concrete, steel and insulated cladding; no modification to the building fabric; every EE and Vodafone phone connects automatically.

Cons: needs a usable outdoor Band 7 signal at the omni; cannot manufacture signal that does not exist outdoors; requires the 10-metre antenna separation rule.

Yes. Band 7 at 2600MHz is shared spectrum used by both EE and Vodafone. The L2000 amplifies the entire Band 7 carrier regardless of which operator SIM is in the phone. Staff on EE and guests on Vodafone both connect to the boosted signal automatically with no app or login. This is the single biggest advantage over a carrier-specific femtocell like the old EE Sure Signal, which only served EE accounts tied to one broadband line.

VoLTE stands for Voice over LTE. It delivers wideband HD audio that sounds noticeably clearer than legacy 2G voice, sets up calls in under two seconds, and lets you browse data while on a call. Because voice now rides on the same Band 7 carrier as data, boosting the L2000 improves both at once. A weak Band 7 signal causes dropped calls, frozen video meetings and slow web browsing simultaneously. The L2000 fixes all three because they share one radio path.

The L2000 does not need a separate voice booster. It does not amplify legacy 2G or 3G on 900MHz, but no modern EE or Vodafone phone uses those for voice anymore. Every handset from the last six years makes calls over VoLTE on Band 7.

All of these MVNOs ride on either EE or Vodafone infrastructure. As long as your phone camps on Band 7 at 2600MHz, the L2000 boosts your signal regardless of which MVNO SIM you use. No special configuration is needed; the amplifier works at the radio layer and does not care which operator name is on the SIM.

O2 uses Band 20 at 800MHz for its low-band 4G, and Three uses Band 3 at 1800MHz and Band 1 in many urban areas. The L2000 is a single-band amplifier tuned only to Band 7 at 2600MHz. It cannot amplify other frequencies. If your staff are on O2 and your phone shows Band 20, the L2000 will light up green and do nothing for you. The correct box is the C2000 at the same GBP835.00, which is tuned to Band 20 800MHz with up to 85dB gain across 2000m2.

Pros of knowing your band before buying: you avoid a GBP835 mistake; you can mix L2000 and C2000 in the same building for mixed networks; you future-proof your IT budget.

Cons: you must install a network info app on a staff phone to read the serving band; mixed buildings need two amplifier units and careful antenna isolation.

75dB downlink gain rebuilds the signal coming from the mast to your phones. 70dB uplink gain lets your phones reach the mast in return. Both directions matter: a booster with strong downlink but weak uplink will show full bars but fail when you try to make a call or upload a photo. The L2000 delivers at least 70dB uplink and at least 75dB downlink, which is the same gain chain as the L1000 but paired with a higher 27dBm output power to cover a larger area.

Output power is what separates the L2000 from the L1000. At 27dBm, the L2000 rebroadcasts the signal 7dB stronger than the L1000 at 20dBm. That 7dB is roughly double the effective coverage area, which is why the L2000 covers 2000m2 while the L1000 covers 1000m2.

Noise figure measures how much hiss the amplifier adds to the signal. A high noise figure (6 to 8dB) turns a clean boosted signal into a distorted one that the phone cannot decode, causing dropped VoLTE calls and slow data even when the bars look full. The L2000 keeps noise figure at or below 4dB, which means the amplifier amplifies the signal without adding noticeable hiss. This is the technical reason VoLTE calls stay clear rather than hissy when 200 users are connected at once.

The L2000 ships with a 7dBi omni-directional outdoor antenna. An omni receives signal from every direction, which is ideal in a town or city where the nearest EE or Vodafone mast could be in any direction. In a dense urban environment with multiple cells on the same band, the omni locks onto the strongest one automatically. A Yagi directional antenna gives higher gain (10 to 15dBi) but only when you know exactly which mast you want and you are far away from it.

Pros of the 7dBi omni: no need to survey mast direction; works in dense urban areas with multiple cells; simpler installation; weather-resistant UV-stable housing; already matched to the 75dB gain chain.

Cons: lower peak gain than a Yagi; in a deep rural valley with one distant mast, a 12dBi Yagi would capture more signal; cannot null out interference from a neighbouring cell.

The indoor panel antenna radiates in a 120-degree fan. A single panel mounted on a central wall at 2.5 to 3 metres height covers roughly 1000 to 1200m2. To reach the full 2000m2 rating, use a low-loss 2-way splitter to feed two panel antennas, one at each end of the space, accepting about 3dB of loss per split. Keep each panel clear of metal ductwork, server racks and fridge units, which shadow the signal.

Critical rule: keep the outdoor omni and the indoor panel at least 10 metres apart vertically (or horizontally with a solid wall between them). If they are too close, the indoor panel feeds the outdoor antenna's own output back into the amplifier, causing oscillation and a triggered AGC shutdown.

The standard L2000 kit includes 10 metres of outdoor-rated 5D-FB coax and 5 metres of indoor cable. 5D-FB loses roughly 6dB per 100 metres at 2600MHz, so a 10-metre run loses only 0.6dB. That is negligible. If your roof-mounted omni needs to feed down three floors to a basement comms cabinet, upgrade the outdoor cable to 20, 30, 40 or 50 metres at point of order.

The L2000 ships with an AC 100-240V UK plug adapter that outputs DC 5V. The box includes the amplifier unit, a 7dBi omni outdoor antenna, a 7dBi panel indoor antenna, 10 metres of outdoor 5D-FB coax, 5 metres of indoor cable, the UK mains adapter, wall brackets and fixings. Optional upgrades at point of order are 20/30/40/50m outdoor cable and an 18kA lightning surge protector for roof-mounted installs.

The L2000 draws at most 12W from the mains. At UK business electricity rates of roughly 34p per kWh, continuous running uses about 10.5 kWh per year. That works out to between GBP12 and GBP18 per year depending on your tariff. Over five years the electricity bill is around GBP60 to GBP90, which is negligible against the GBP835.00 upfront cost and the value of a fixed 4G signal across 2000m2.

Step one: fix the 7dBi omni outdoor antenna to the roof or the highest external wall, pointing vertically. Step two: run the 10m 5D-FB coax through the eave or a drilled wall entry point into the building. Step three: mount the 7dBi indoor panel on a central wall at 2.5 to 3 metres height, facing the work area. Step four: connect both coax cables to the amplifier unit. Step five: plug in the UK adapter and wait for the green LED. Keep the outdoor and indoor antennas at least 10 metres apart vertically. The whole process takes 20 to 25 minutes for a facilities team.

The amplifier is 180 by 120 by 28mm and weighs very little. Mount it on a wall bracket or place it on a shelf in a comms cupboard, reception cabinet or plant room within 5 metres of where the indoor panel cable ends. Keep it ventilated, away from heat sources such as boiler flues, and within reach of a UK mains socket. The unit has an LED that glows green when the system is locked and amber or red if oscillation is detected.

Hotel (60 rooms, 2000m2): The 200-user rating handles breakfast check-in rush. Mount one panel per floor. Guests on EE and Vodafone connect automatically.

Warehouse (steel frame): Mount the omni as high as possible on the external wall, not under the roof canopy. Expect 15 to 30Mbps on the warehouse floor for scanners and PDAs.

Production floor: MES tablets and IoT sensors need a steady floor. The 27dBm output punches through machine guarding. Mount panels away from CNC machines and stainless steel cabinets.

Enterprise office (80 staff): Mount the omni on the roof. Run coax to a comms cupboard. Mount the panel on a central column. Expect 25 to 45Mbps at every desk.

Garage or underground car park: Run the coax up to the roof for the omni and bring the panel down. Order the 20m or 30m cable upgrade.

Metal building: Corrugated cladding is the worst case. Mount the omni on a pole extension above the roofline. Expect 15 to 25Mbps inside.

Retail complex: Card terminals and customer mobiles need a steady floor. The 200-user rating handles Saturday browsing crowds.

Oversized detached home: Over-specified for a normal house but right for a 20-staff home office or a 10-bedroom holiday let.

The 200-user rating is the number of active cellular connections the amplifier can serve at peak, not 200 people on calls at once. It covers staff phones, guest phones, payment terminals, scanners, security cameras, smart locks and environmental sensors. A 2000m2 hotel with 60 rooms and 40 staff easily hits 150 to 180 active connections at breakfast.

In enterprise test sites, the L2000 lifted measured download from 1 to 5Mbps deep inside the building to 15 to 50+Mbps at the desk. Upload rose from 0.5 to 2Mbps to 8 to 25Mbps. Reception desks see 35 to 55Mbps, open-plan offices 25 to 45Mbps, warehouse floors 15 to 30Mbps, and boardrooms 15 to 25Mbps. The exact number depends on the outdoor signal level at the omni.

The L2000 is Ofcom licence-exempt and carries UKCA and CE certification. Its built-in automatic gain control keeps the uplink within legal limits, so you do not need to apply for a licence or notify the nearest cell site. This is a significant advantage over a carrier-installed small cell, which requires months of approval and a formal site agreement.

Automatic gain control monitors the uplink in real time. If the indoor panel feeds the outdoor antenna's own output back into the amplifier, the AGC detects the loop and reduces gain to protect the mast from interference. This is why the L2000 is legal to use in the UK without a licence. However, AGC is a safety net, not a substitute for the 10-metre antenna separation rule. If the antennas are too close, the AGC will throttle the gain and you will lose coverage.

If you mount the omni on the roof or on a tall external pole, the 18kA inline lightning surge protector is strongly recommended. A roof antenna in an exposed location is a natural strike target, and a nearby strike can induce a voltage spike that travels down the coax and destroys the amplifier. The surge protector is a small fraction of the GBP835.00 cost of the amplifier. If the omni is mounted on a low external wall below the roofline and sheltered by taller neighbouring buildings, the surge protector is optional but still cheap insurance.

The L1000 at GBP535.00 is the smaller brother. Both share Band 7 2600MHz, the same 70/75dB gain, the same 7dBi antenna philosophy, the same UK plug and the same 180 by 120 by 28mm chassis. The differences are output power, coverage and user count.

Pros of L2000: 7dBm more output; double coverage; double users; one box for a 2000m2 floor plate.

Cons of L2000: GBP300 more; over-specified for a 1000m2 space.

The C2000 at the same GBP835.00 is the Band 20 800MHz twin. Same price, same 2000m2, same 200-user rating. The only difference is the frequency. The C2000 delivers up to 85dB gain on the lower frequency, which penetrates stone and rural terrain better but yields lower peak data speeds (10 to 25Mbps vs 15 to 50+Mbps).

If your phones show Band 7 at 2600MHz, buy the L2000. If they show Band 20 at 800MHz on O2, buy the C2000. When in doubt, install a network info app on a staff phone and read the serving band before ordering.

Yes. Running one L2000 on Band 7 and one C2000 on Band 20 side by side gives dual-band coverage for mixed EE/Vodafone and O2 users. They must be on separate antennas with at least 10 metres isolation between each pair to avoid oscillation. This is a common setup in hotels and mixed-use enterprise buildings where guests bring SIMs on all four UK networks.

EE discontinued Sure Signal, the consumer femtocell, and no longer supports new business installations. The L2000 is the open-market alternative. Unlike Sure Signal, which was tied to one EE account and one broadband line, the L2000 boosts the actual Band 7 signal for every EE and Vodafone phone automatically. It does not require a fibre connection, does not tie to a contract, and covers 2000m2 rather than a single room.

If you are deep in the countryside where Band 7 at 2600MHz barely reaches the outdoor antenna, the C2000 on Band 20 800MHz is the safer purchase. Band 20 travels further and penetrates rural terrain and listed stone buildings better. The L2000 is the right choice when you have a usable (even weak) Band 7 signal outdoors but the building itself kills it. If your roof omni captures less than -110dBm on Band 7, the L2000 will help less than the C2000 would on Band 20.

For EE and Vodafone users in a 2000m2 UK enterprise building in 2026, the L2000 at GBP835.00 is the best Band 7 2600MHz 4G LTE and VoLTE booster you can buy. It delivers 70/75dB gain, 27dBm output, 200 simultaneous users and VoLTE HD voice, lifting measured 4G from 1 to 5Mbps to 15 to 50+Mbps across the whole floor plate. It is Ofcom licence-exempt, UKCA/CE certified, draws under 12W and installs in 20 to 25 minutes.

Choose the L2000 at GBP835.00 for a 1800-2200m2 hotel, warehouse, production floor or enterprise office on EE or Vodafone. Choose the L1000 at GBP535.00 only if your floor plate is under 1200m2. Choose the C2000 at the same GBP835.00 only for O2 Band 20 or rural Band 7 dead zones. Choose the D2000 at GBP545.16 only for EE Band 3.
